In today’s medical market, front-end decisions that designers make can have a lasting impact on manufacturability, patient and practitioner satisfaction, and time to market.

Designing for manufacturability of interventional devices

Selecting the right process aids while designing for manufacturability (DFM) of interventional devices such as stents can have a significant impact on manufacturing time and costs. Use of traditional FEP medical tubing process aids may cause difficulties and inefficiencies that are easily avoided with strategic design and concurrent engineering. The use of flexible polyolefin-based solutions, such as TE Connectivity’s MT-LWA medical tubing, can realise processing efficiencies with an easy-to-peel (without the use of blades), no-need-to-skive design, or eliminating adhesives and mastics in joining operations.

MT-LWA is perfect for reflow applications where FEP shrink ratios are not suitable, has excellent tear propagation, and its optical clarity and optional controlled shrink force make it an exceptional process aid for hot jaw bonding and laser-weld applications such as balloon bonding.

The right medical electrical connectors for signal and power transmission

Choosing the right medical connector for patient monitoring and diagnostic equipment often requires easy, ergonomic electrical connections over many mating cycles. Additionally, requirements for a ‘break-away’ function for emergency release can also be essential in critical situations.

Medical connectors such as the ODU MEDI-SNAP Break-Away connector provide effortless, ergonomic connection, while also featuring ‘snap locks’ that can unmate the connector with one pull of a specified force on the cable. An over-moulded plastic, plugand- play design shortens development time, and reduces cost and weight.

Fit-for-purpose wire and cable

As medical equipment technology becomes ever more capable, intelligent and complex, the need for space-saving solutions to wire routing and harnessing challenges becomes more pronounced. The AlphaWire ECOGEN and MicroCoax series of medical-equipment-focused wire and cable are ready to meet the miniaturisation, space-efficiency and weight-savings demands of the industry, while providing the requisite signal integrity and physical robustness that has always been essential.

AlphaWire EcoCable and EcoFlex control cables in flexible and shielded/unshielded configurations are up to 47% smaller and 65% lighter than traditional PVC jacketed cable, while EcoWire hook-up wire provides similar benefits for internal wiring of equipment.

The AlphaWire Micro Coax series of coaxial cables are available down to a smaller 50 AWG size with outstanding dielectric properties for the low capacitance and consistent impedance required for coaxial applications, such as medical probes, endoscopy, oximetry systems and more.

Finding the right partnerships

Successful medical device and equipment design goes beyond achieving design targets and selecting the right componentry. The right partnerships can go a long way in ensuring that a successful design translates into equal success for patients, practitioners, regulatory processes, organisational goals and business financial goals.
