Medical Laser Wire Stripping

The Medical market has a high level of need for the capabilities of laser wire stripping solutions due to the combination of requirements for very high quality coupled with ever more complex and delicate wiring systems.

The following is a non-exhaustive list of common applicationsMedical_multiconductor


General Wiring

General purpose equipment cabling within a unit and between devices. Typically made up of shielded cables or as the example here, multiple layers of shieldedcables. See General Wire Types and Mercury wire strippers for the best solutions for stripping these polymer insulations

Catheter wiringpolyimide_windows

Catheters are used to guide a medical probe or device to the required tissue. The highest demands are placed on reducing wiring size to improve manouvrability and increase functionality. Typical applications include RF ablation where the catheter carries multiple conductors including a number of thermocouples as well as the RF ablation signal.

This fine wiring tends to be manufactured using either enamel (e.g. polyimide) coatings or bio-compatible fluoropolymers.

Pacemaker Electrodes

coilsThese flexible, spring-like, electrodes pose special challenges to laser ablation due to their fluro-polymer coatings and sensitivity to heat during processing. For more detail see our pacemaker electrode solution discussion and our Pioneer wire stripper.

Small_enamel_coilHigh performance motor windings

Medical power tools, such as drills used in brain surgery must have the highest levels of quality. Traditional mechanical brushing and abrading of enamelled motor windings can introduce dangerous particulates. Our Odyssey range of wire strippers give a perfect solution for this application. See our magnet wire stripping solution for more information.

Hypodermic Tubing coatingsHypo_Tube

The hypotube is a long metal tube with micro-engineered features along its length. It is a critical component of minimally-invasive catheters, used in conjunction with balloons and stents to open up clogged arteries. The balloon portion of the catheter is attached to the head of the hypotube. In manufacturing such devices it is necessary to remove part of the extruded coating (such as PTFE, ETFE or nylon based compounds). Laser removal is proving popular over more traditional blade based methods primarily due to the ability to automate the process. See the Medical Coatings solution for more information.

Fine wire applications

48_AWG_hearing_aid_wireSmall gage single conductors are very common in medical devices, whether found in a catheter delivered device or in a cochlear impant or hearing aid.

We specialise in solutions to remove insulations from wires down to and beyond 50 AWG without damage to the conductor. Depending on the insulations used a particular laser solution is required. See our Fine Wire solutions for more information

Micro-coax ribbonsMicrocoax_magnified

Shielded coax are found in a great number of medical device interconnects. A classic example is that of the ultra-sound cable. High density, high frequency signals have to be transmitted with the most flexible cabling possible - dictating very small conductor sizes in high density micro-coax ribbons.

See our discussion on micro-coax ribbon stripping in our solutions section.
