Philippe Pouletty, M.D., CEO of Truffle Capital and Founder of Carvolix, describes the evolution of heart valve replacement and the significance of AI-guided robotics in expanding access to transcatheter procedures. The company's biomimetic mitral valve and AI software that guides valve placement using a mini robot are making these procedures safer and easier for less experienced cardiologists to perform.  The technology is also being adapted to treat brain strokes by enabling a larger pool of cardiologists to quickly perform necessary interventions. Philippe explains, "At Truffle Capital, are what we like to call ourselves Business Builders, which is to say we're not just going to start small companies, we are going to try and build world leaders to revolutionize medicine. For Carvolix, this means interventional cardiology as well as the treatment of brain strokes. As you know, replacing heart valves is a major medical need. We have four heart valves that open and close 50 to 100 times per minute, which can get calcified and dysfunctional with time and need replacement. So 40 years ago, you would go to a skilled surgeon who would say, "Okay, I'm going to open your chest. I'm going to stop your heart, and I'm going to sew a new valve."   "But recently we decided to lead the new revolution, which is a small robot based on artificial intelligence, that could autonomously, under the clinical supervision of a cardiologist, replace a valve. We think that this new revolution is going to allow many more patients to benefit from aortic, mitral, and tricuspid valve replacement, even in smaller cardiac centers and among younger cardiologists. A similar revolution happened in the cockpit of Boeing and Airbus planes when the autopilot, the GPS systems, and satellite systems brought autonomy to planes." #Carvolix #CardiacNews #PatientCare #HealthTech #Cardio #AIinHealthcare #InterventionalCardiology #StrokeCare #MedTechInnovation #RoboticsInMedicine #TAVI #Thrombectomy #DigitalHealth Carvolix.eu Download the transcript here

In this short podcast from the Bry-X stage of the 7th Annual HVACR Training Symposium, Matthew Taylor from Kalos Services introduces refrigeration pulse valves, which started as a solution for CO2 refrigeration systems and are now common in commercial refrigeration as a whole. He briefly explains how they work and describes their role in the refrigeration systems (and possibly commercial HVAC systems in the future!). Refrigeration systems have moved away from electronic expansion valves (EEVs), which have been adopted by residential HVAC systems only recently, and have been using pulse valves instead. Pulse valves are also electronic expansion devices with fewer parts than EEVs (which often have stepper motors and complex electronics) and lower failure rates as a result. Pulse valves have a pressure transducer and a temperature sensor that go on the suction line to calculate the superheat; these report to a controller that takes the data from those parts, calculates the superheat based on the refrigerant and programming, and controls the valve like an EEV. However, there are only two wires, and the controller turns the valve on or off (like a solenoid) instead of sending pulses out. Solenoids just open or close completely, but pulse valves have a port (oversized fixed orifice) through which liquid refrigerant passes; when the load changes, the controller merely sends power to open the valve when the load goes up and stops sending power to close the valve when the load goes down. The valve is open for a certain percentage, and the on/off function is open for that amount of time in a six-second duty cycle (and off for the remaining time); this is pulse-width modulation. They also work well with refrigerants that have glide. However, pulse valves have some challenges. They may have issues in cases where we have very long evaporators, as there are delays between what happens between the inlet and outlet. Having multiple, shorter evaporators is a common solution to this problem, and these designs are more efficient in general (especially when they can be used with efficient refrigerants that move slowly through the evaporator). Pulse valves also require a computer (though EEV ones are similar), and are less serviceable than other valves; some may require technicians to take the valve apart to take the screen out, which requires replacement O-rings and gaskets. They are also noisy enough for customers to hear them.   Have a question that you want us to answer on the podcast? Submit your questions at https://www.speakpipe.com/hvacschool.

**Boys and Girls, We're Back! Tyler from MORRFlate Returns – Tire Inflation Wars, Copycats, Patents & Off-Road Innovation** We're back with another awesome episode of the Jeep Talk Show! Tyler from MORRFlate joins us again for a raw, honest conversation about building a business in the off-road world, dealing with big-time copycats, patent battles, and why competition (the right kind) actually drives innovation. Tyler has been wheeling Toyotas all over California since he was a kid, lives close to the Rubicon Trail, runs NorCal 4x4 Rescue, co-hosts the Snail Trail 4x4 Podcast, and has poured serious support into trail advocacy. In this return visit (first one was back in September 2025), he opens up about getting threatened by a major player, the reality of enforcing patents, and how a $3M company competes against $45M giants with deep marketing pockets. We dive deep into: - How MORRFlate's 4-tire inflation/deflation system works (connects all four tires as one big air tank, equalizes pressure automatically, saves massive time on the trail) - The frustration of direct copies (even stealing the signature neon green color) - Why patents aren't the silver bullet everyone thinks - Airflow limitations of Schrader valves and future ideas to fix the bottleneck - Building a company from a garage condo to a team of 8+ with a warehouse in Sacramento - Lifetime warranties, obsessive quality control, and hiring fellow off-roaders - AI chatbots on the website, robots in manufacturing, and how AI is changing marketing and product design Tyler also shares his 30-second elevator pitch: MORRFlate makes airing up and down your tires super convenient so you can actually enjoy the trail instead of babysitting a compressor. If you've ever deflated for traction, fought with individual tire hoses, or dreamed of faster air-ups on your Jeep, Toyota, or any rig — this one's for you. **Timestamps:** 00:00:00 Show Opening 00:00:10 Misnaming Moore Flat 00:00:31 Tyler's Background & Sales 00:01:19 Previous Interview & Threats 00:02:06 Acquisition Threat & Patent Journey 00:03:08 Patent Approval & Copycats 00:04:01 Company Name Confidential 00:04:33 Patent Enforcement Costs 00:05:21 Competition and Innovation 00:06:35 Amazon Listings & Pricing 00:08:03 RealTruck Ownership Impact 00:09:12 Podcast Monetization Issues 00:09:41 Morfleet Product Overview 00:11:07 Tire Deflation Benefits 00:12:59 Airflow Limits of Valves 00:13:28 Air Tank Volume Calculations 00:14:43 Limited Tank Capacity Demo 00:15:46 Compressor Performance Insights 00:16:24 Personal Projects & Ideas 00:17:40 Upcoming Valve Projects 00:19:07 Valve Interior Flow Restriction 00:21:41 Heavy Equipment Valve Solutions 00:23:48 Apex Rapid Valve Review 00:24:15 Challenges with Large Tires 00:24:59 Passion for Problem Solving 00:29:04 Warehouse & Quality Control 00:34:48 Lifetime Warranty Strategy 00:37:02 Customer Focus Assurance 00:38:22 Employee Attitude Culture 00:39:50 Testing Competitor Gear 00:40:51 People-Centric Philosophy 00:43:28 Corporate vs Small Business 00:44:07 Politics and Truth 00:45:47 Vendor Conflict Over Copying 00:49:05 AI Chatbot Deployment 00:50:30 AI, Quality Control & Robotics 00:53:25 AI in Product Design 00:54:51 AI Impact on Jobs 00:57:45 Minimum Wage Debate 00:58:49 Digital Media & AI 01:02:40 Show Recap & Future 01:04:25 Closing Thanks 01:06:38 Final Thanks & Friendship 01:09:02 Interview Conclusion **Links:** - MORRFlate Official Site: https://morrflate.com/ (Check out the Quad hose kits, Air Hub, and play with their AI chatbot!) - Tyler on Instagram/X: @4x4ToyotaTyler - MORRFlate on Social: @morrflate - Snail Trail 4x4 Podcast: Search "Snail Trail 4x4" on your favorite platform (830+ episodes!)

Most engineers don't start their careers thinking, “I can't wait to manage people.”They want to build things. Tinker. Solve hard problems. See hardware fly.In this episode, Brian Ippolito from Marotta Controls talks about what it's been like to grow inside a third-generation aerospace company that grew from about 130 people to nearly 1,000 during his career.We talk about the moment you stop being someone's peer and become their manager, and how uncomfortable that shift can be. Brian shares what actually changes when you move from leading a team to leading leaders, and why simple advice like “hit the forward button more” is harder to put into practice than it sounds.He also explains the very real “Bob from Valves” problem in manufacturing. When critical knowledge lives in one person's head, it feels efficient until it becomes a risk. That's part of the reason they built “Valve Camp,” an onboarding program that brings engineers, technicians, and even HR closer to the product so everyone understands the mission.Throughout the conversation, Brian reflects on how Marotta has kept its family-company culture while competing in aerospace and defense for more than 80 years, building hardware that has flown from the Apollo era to today's heavy-lift rockets.If you are an engineer moving into management, leading technical teams, or trying to scale without losing what makes your company special, this episode is for you.Marotta Controls continues to grow across engineering, manufacturing, and support roles.

Minimally invasive cardiac surgery (MICS) is one of the techniques used by cardiac surgeons to repair or replace valves, including the mitral valve. While the procedure has a shorter recovery time than the traditional sternotomy, it is still an open heart operation, and not the same as the minimally invasive techniques used by interventional cardiologists. SMH Chief of Cardiovascular Surgery Jonathan Hoffberger, DO, explains the different options, and how the heart team approach helps to pair the right patient with the right procedure.

In this episode of BackTable, host Dr. Sabeen Dhand sits down with Dr. Kumar Madassery for a detailed discussion of procedural strategy, technical decision-making, and real-world troubleshooting in DVA. --- SYNPOSIS Dr. Madassery walks through his approach from pre-procedure planning to final scaffolding. The conversation begins with imaging review, patient selection, and anesthesia considerations, emphasizing how preparation influences technical success. They then examine venous mapping and access strategy, with specific attention to femoral and tibial disease patterns and how these anatomic variables shape crossing techniques.This episode also covers wire and catheter selection, techniques for creating the arteriovenous anastomosis, balloon sizing, valve management, and stent scaffolding. Throughout, Dr. Madassery shares practical solutions to common access challenges and highlights decision points that can determine procedural durability. The discussion closes with reflections on clinical management, operator fatigue, and the value of professional networks when navigating complex limb salvage cases. --- TIMESTAMPS 00:00 - Introduction03:08 - Pre-Procedure Imaging and Setup05:01 - Venous Access and Mapping07:27 - Anesthesia and Patient Preparation12:29 - Femoral and Tibial Disease Considerations23:17 - Crossing Techniques and Tools27:16 - Venous Access Challenges and Solutions35:54 - Creating the Anastomosis37:03 - Balloon Sizing and Scaffolding Techniques38:26 - Navigating Venous Access Challenges39:56 - Wire and Catheter Strategies42:08 - Dealing with Valves and Anastomosis44:16 - Proximal vs. Distal DVA Approaches47:01 - Scaffolding and Stent Techniques50:06 - Clinical Management and Case Fatigue01:01:10 - Networking and Seeking Advice01:05:41 - Concluding Thoughts and Future Directions

Vacuum tubes are supposed to be extinct yet here we are in 2026 still arguing swapping and occasionally getting electrocuted. In this episode Mitch Anderson, Eric Pye, and Jeremy Sikora strip the romance out of valves and talk about why they still matter without leaning on lazy audiophile clichés. The discussion cuts through tube rolling reality versus placebo and the ongoing new production versus NOS debate. It also looks at why Ray Tubes are suddenly on everyone's radar and what Jeremy's amp building class at the American Wireless Communication Museum teaches you that spec sheets never will.Along the way, we connect the dots between Talk Talk's obsessive studio craft, Miles Davis with Jimmy Cobb's unshakable timing, and the Tron soundtrack, while getting very real about tube amp safety; from blown parts to painful zaps, because high voltage does not care how experienced you think you are.Thank you to SVS and Shure for their support of our programming!https://www.svsound.comhttps://www.shure.comCredits:• Original intro music by The Arc of All. https://sourceoflightandpower.bandcamp.com• Voice Over Provided by Todd Harrell of SSP Unlimited. https://sspunlimited.com• Production by Mitch Anderson, Black Circle Studios. https://blackcircleradio.comDon't forget to check our website for daily updates on the latest electronics, news, recommendations, and deals on high-end audio, loudspeakers, earphones, TVs, and more.https://www.ecoustics.com#raytubes #vacuumtubes #audiovalves #vinylcommunity #audioloveyyc #budgetaudiophiler #blackcircleradio #ecoustics #hifi #audiophile #hometheater #listeningroom #musicindustry #analogaudio

We started by talking about our musical instruments, which we loved deeply in theory and stored carelessly in reality, proving that passion and maintenance are not the same skill set. In high school we somehow managed to be both band kids and athletes, demonstrating that blowing into brass and colliding with linebackers can coexist as long as no one asks too many questions. We treated our instruments like priceless treasures while also leaving them in car trunks during temperature swings that would alarm a meteorologist. Naturally this led us to celebrity culture, where authenticity is expected to be spontaneous but professionally managed at all times. We used Kid Rock as an example, mostly because nothing says “quiet spiritual reflection” like stadium lighting and pyrotechnics. We discussed how celebrities are supposed to represent their faith publicly, but only in ways that don’t inconvenience their brand managers. We wrestled with the idea that when a famous person talks about Christianity, we immediately suspect a marketing strategy, yet when they don’t talk about it, we suspect cowardice, which is a terrific system. Wealth came up, because apparently following Jesus is simple until your house has more square footage than the New Testament. We examined how fame turns every belief into a press release and every doubt into a headline. Hollywood, of course, typecasts everyone, including people who are just trying to have a thought, which makes it difficult to be a nuanced human when you’ve already been labeled “The Faith Guy.” We reflected on interviews, where the goal is often to sound natural while answering pre-approved questions in a room full of lighting equipment. In the end we concluded that genuine conversation is surprisingly rare, mostly because it involves two people talking without a script, which in modern media qualifies as reckless behavior.

How did transplanted heart valves grow in comparison to standard homografts and how did the valvular function differ with time? Is there a minimum dose of immunosuppresion that can protect these valves and can this dose be lower than full heart transplantation immunosuppresion therapy? Is partial heart transplantation considered a potential life-long approach to valve replacement or mostly something used to allow for growth of valves during childhood? What do we know about the world's limited experience in humans of this approach? Dr. Rajab shares the answers this week in an exciting 'sci-fi' episode.

Valves are sticking all over as the hosts give advice on how to avoid pulling cylinders. Send your questions to podcasts@aopa.org for a chance to be on the show. Join the world's largest aviation community at aopa.org/join Full notes below: Rick has a 182 with a new Pponk engine and he's burning lots of exhaust valves. He's wondering what he should change operationally. Paul said to borescope more frequently to find the asymmetric burn patterns before they need to be replaced, and if they start to have asymmetric patterns to lap them immediately. He recommends borescoping every 100 hours. Mike gives some initial results of Savvy Aviation's borescope initiative, which after 100,000 images found that 7 or 8 percent of valves showed signs of heat distress. Twenty five percent of the engines had at least one valve that was heat distressed. About 85 percent of those valves were in the early stage of distress and could be lapped. Only about 15 percent were considered late stage.   Brad has an SR22 with an IO-550 that had high oil usage. They pulled a cylinder, rehoned it and put on new rings. Later he started asking questions about torquing the through bolts, and the shop told him they held a wrench on the other side, but didn't torque both sides. He's wondering if he should go back and retorque the bolts. Mike and Paul think he's probably ok.   Bruce is sick of sniffing gas fumes. They installed new fuel senders and a digital fuel gauge in their 172. They followed the procedure to calibrate the fuel senders, but he's having trouble getting it correct. He's as much as two gallons off from what it should be. Paul starts by asking what bucket Bruce is using because the utility buckets from the home stores are unreliable as calibrated containers, he said. The other issue is the wet wing construction, which can lead to dams that make it difficult to fully defuel or refuel. Bruce has even accounted for temperature. He's within half a gallon on one side, which Paul said is usually as close as you can get it. Ed is stirring the pot. He read that in an article in the American Bonanza Society publication that operating lean of peak is bad for engines. Obviously the hosts disagree, and a discussion of the merits of rich of peak and lean of peak ensues.
