Medical Device Measurement Selector for Catheter Engineers

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

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.

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  

What happens when a manual finishing process becomes a production bottleneck? For a medical device manufacturer in the St. Louis region, our engineering team developed an automated finishing process for titanium medical components, replacing a labor-intensive hand blasting operation while producing a uniform matte surface finish. It's another example of how process development can help manufacturers improve consistency while reducing manual labor.

Biomedical Equipment Mastery Series ⚕️ ECG Machine Calibration, Preventive Maintenance & Troubleshooting An ECG machine must deliver accurate and reliable recordings to support clinical decision-making. Regular calibration, preventive maintenance, and systematic troubleshooting are essential to ensure optimal performance and patient safety. ⚙️ Calibration • Verify the standard calibration signal (1 mV = 10 mm). • Check paper speed settings (typically 25 mm/s and 50 mm/s). • Confirm waveform accuracy using an ECG simulator. • Ensure all leads produce consistent and accurate signals. 🛠️ Preventive Maintenance • Clean the electrodes, lead wires, and patient cables after use. • Inspect cables and connectors for wear, damage, or loose connections. • Check the thermal printer, paper quality, and battery condition (portable ECGs). • Verify display, buttons, alarms, and accessories are functioning properly. • Perform periodic performance verification as recommended by the manufacturer. 🔍 Common Problems & Troubleshooting Problem: No ECG waveform Possible Cause: Loose/disconnected leads or poor electrode contact. Solution: Reconnect leads and replace or reposition electrodes. Problem: Noisy or distorted waveform Possible Cause: Patient movement, dried electrodes, or electrical interference. Solution: Minimize movement, replace electrodes, and reduce nearby electrical noise. Problem: Baseline drift Possible Cause: Poor skin preparation or loose electrodes. Solution: Prepare the skin properly and ensure secure electrode placement. Problem: Paper not printing Possible Cause: Empty paper roll or printer malfunction. Solution: Reload thermal paper and inspect the printer mechanism. #BiomedicalEngineering #MedicalDevices #ECG #MedicalEquipment #ClinicalEngineering #PreventiveMaintenance #Calibration #Troubleshooting #BiomedicalEquipmentMastery #MedicalEquipment
