Plated Pull Rings in Structural Heart Delivery Systems

💡 The push for lower-profile transcatheter delivery systems in structural heart interventions is running into a physical roadblock: traditional mechanical marker bands. While crimped bands provide the fluoroscopic visibility needed to track TAVR or LAA closure systems, they add bulk, create rigid kink points, and introduce a risk of dislodgement when navigating complex cardiac anatomy. To overcome these limitations, medical device engineers are shifting from mechanical bands to #selectiveplatinum or gold #electroplating. By depositing an atomic layer of platinum or gold directly onto specific sections of guidewires or catheter braids, developers achieve high-contrast radiopacity with zero profile growth and smooth mechanical transitions. Partnering with an ISO 13485:2016 certified plating specialist ensures excellent adhesion, tight tolerances, and predictable performance under real-time imaging. 🚀 How is your #engineering team tackling the balance between device visibility and miniaturization? Let's discuss in the comments. 👇🏻 #MedTech #MedicalDevices #StructuralHeart #CatheterDesign #Electroplating #ProPlate #ISO13485

As structural heart devices continue to move toward lower-profile, more complex delivery systems, radiopacity can no longer be an afterthought. Selective platinum and gold electroplating offer an elegant alternative to traditional marker bands by providing exceptional fluoroscopic visibility without increasing device profile or compromising flexibility. The result is improved tracking, more precise deployment, and the potential for safer, more efficient procedures. Proud of the work our engineering team is doing to help MedTech innovators solve these challenges.

Spiral torsion springs give medical devices rotational force from a flat, space-saving profile, which is why they appear in drug delivery devices, dose dials, and surgical instruments. This week Inside the Device looks at the spring that turns. Most springs push or pull in a straight line. A spiral torsion spring rotates. Flat strip material, wound into a spiral, delivering torque as it winds and a controlled return as it releases. Why device engineers reach for it: 🔹 Rotational return in tight axial space. 🔹 Smooth, predictable torque through the range of motion. 🔹 Consistent performance across thousands of cycles in reusable platforms, or reliable single actuation in disposables. Where you will find one working: the dose dial on a pen injector. The cap return on an autoinjector. The controlled ratchet of a hinged surgical instrument. One question worth asking any spring supplier for a device program: are they ISO 13485:2016 certified, and can they support your design from prototype through production? WE CAN! The best spring in a device is the one you never think about. #MedicalDevice #InsideTheDevice #DrugDelivery #SpringDesign #MedTech

Integrating electrodes onto a balloon catheter introduces a completely different set of engineering challenges than building the balloon itself. The balloon still needs to inflate predictably, maintain its intended geometry, and navigate complex anatomy. At the same time, conductive elements must remain securely integrated throughout manufacturing, catheter assembly, and repeated inflation cycles without compromising device performance. Balancing mechanical performance with electrical integration requires careful consideration of materials, bonding methods, balloon geometry, and manufacturing processes from the earliest stages of development. As minimally invasive devices continue to become more sophisticated, successful programs increasingly depend on bringing these engineering disciplines together rather than treating them as separate design problems.

The most important spring in a medical device is often the one nobody notices. Spiral torsion springs earn that invisibility in a way no other spring can: they deliver rotational force from a package that's almost completely flat. Most springs push or pull in a straight line. Spiral torsion springs rotate. A flat strip of material, wound into a spiral, produces torque that increases predictably with angular deflection. Smooth. Repeatable. And all of it packed into a thin, compact envelope that fits where a coil spring simply won't. That combination of rotation and compactness makes spiral torsion springs the preferred choice for: 🌀 Trigger and handle return in surgical instruments 🌀 Dose dials and metering mechanisms 🌀 Hinged housing and lid return 🌀 Needle shield and guard rotation 🌀 Counterbalancing rotating components In non-contact designs, the coils never touch during deflection. No intercoil friction means minimal hysteresis, so the torque curve stays clean across the working range. That matters when a clinician's tactile feedback depends on the spring behaving the same way on actuation 1 and actuation 10,000. The right conversation with a spring engineer starts early: ✔️ What torque is required at the working position? ✔️ How many degrees of rotation does the mechanism need? ✔️ What envelope is available, especially axial width? ✔️ Reusable or single-use? ✔️ What quality and regulatory requirements apply, including ISO 13485:2016? Spiral torsion springs aren't a drop-in replacement for other spring types. They're a precision solution for applications where rotational force in minimal space is the requirement, and where that requirement has engineering consequences if it isn't met. Where in your next device design does rotation live? #MedicalDevices #MedTech #MedicalDeviceDesign #SpiralTorsionSprings #SpringDesign #Engineering

Engineering Inside Medical Devices | Part 5 How do engineers know a reflector is ready for the operating room? A mirror-like finish can be misleading. In medical devices, appearance alone is never enough. Every reflector must demonstrate consistent optical performance—not only on the day it is manufactured, but throughout its service life. That means verifying more than reflectivity. Engineers also evaluate coating adhesion, resistance to temperature and humidity, and the durability of the protective lacquer. Because in medical engineering, reliability is not assumed. It is verified. Next: Why isn't the most popular coating technology always the best choice? #EngineeringInsideMedicalDevices #MedicalDevices #Engineering #Manufacturing #Optics #Quality #Reliability

In this episode of our catheter build series, we move on to removing the catheter shaft from the mandrel. It might seem like a straightforward process, but small details make a big difference. Opening the ends to eliminate the vacuum, carefully trimming away excess PTFE, securing the assembly correctly, and removing the shaft without damaging the structure all require patience, control, and experience. These are the kinds of practical manufacturing skills that are difficult to learn from a textbook but are essential for anyone developing minimally invasive medical devices. Follow along as we continue building this catheter shaft step by step, exploring the materials, processes, and engineering decisions behind what appears to be a simple tube. What manufacturing step do you think is most underestimated in catheter development? #MedTech #MedicalDevices #Catheter #CatheterDesign #Engineering #Manufacturing #ProductDevelopment #RandD #BiomedicalEngineering #MedicalEngineering #STEM
