Engineering Balloon Catheters with Integrated Electrodes

💡 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.

Great callout on the limitations of traditional marker bands in lower-profile structural heart delivery systems. Another area worth highlighting: plated pull rings. In certain structural heart delivery systems, plating can add visibility and functionality without relying on loaded polymers or additional marker bands. As devices continue to get smaller and more complex, selective plating gives engineers another way to balance visibility, profile, and mechanical performance.

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

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.

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

🔬 Our customer required assistance in the development of a complex, high volume biosensor device that required tight tolerances and fast, very accurate assembly. ADDEV Parafix were heavily involved in the design and development of the biosensor components using laser, plotter and tooled development parts through our R&D Department. Optimum designs and materials were determined, resulting in the production of five components with very specific functions, including a flow cell, made with an inert diagnostic spacer tape, a flow cell lid using a hydrophilic film, a microporous mesh for air flow and barrier to liquid, a component for recognition in vision systems and a PET backing to provide stiffness and enhance aesthetics. We identified suitable materials and developed the biosensor components and assembly process, incorporating our automated assembly equipment for quick and very accurate assembly.

Pulsed Field Ablation (PFA) is changing more than cardiac care, it's changing how catheters need to be manufactured. Unlike traditional thermal ablation technologies, PFA performance depends on the precise geometry of complex multi-electrode catheter designs. That means manufacturing success is no longer just about controlling individual processes- it's about controlling the entire system. As device complexity increases, manufacturers are moving beyond standalone workstations toward integrated automation that combines precision assembly, inline metrology, vision inspection, and closed-loop process control. In our latest article, we explore why PFA is raising the bar for catheter manufacturing and what it means for the future of medical device automation.
