Teflon wrap underneath Braid helps with stripping and prevents abrasion of inner wires from braid during cable flexing.
Braided tinned copper shield, reduces cable flexibility but increases resistance to mechanical failure, and provides signal shielding for the data wires within the cable.
TPE Jacket selected for good biocompatibility properties and durability to survive repeated use.
Sub bundles individually foil shielded for signal integrity.
Wires split into sub bundles for signal isolation purposes. Wrapped together in teflon to keep sub bundles together and protect individual shields from abrading on outer shield, and keeps outer and inner shields independent.
Crimp style contacts applied for insertion into molex or similar housing.
Some splices added to create jumpers for common grounds. This reduces the number of wires in the cable and helps reduce cable size.
Pins crimped on prior to insertion into custom connector housing.
More jumpers.
Pins inserted into custom connector
Back end filled with potting material to immersion proof and help prevent damage during overmold process.
Materials selected to ensure adherence of overmold to connector.
Material selected to ensure bonding of overmold and cable jacket.
These selections along with a water proof connector allow the cable assembly to survive the cleaning process without risk of trapping cleaning fluid or shorted contacts.

Minnesota Wire utilizes a variety of advanced manufacturing methods to produce custom cable assemblies, medical cables, and medical wire.
Patient Monitoring Systems
Patient-to-Monitor Cable Assembly
Custom EMG patient cable for measuring the amount of trauma a patient has incurred to muscles. The signals are so small that any noise in the cable will interfere with the monitoring. Special low-noise materials are used in the cable and terminations to reduce noise.
Minnesota Wire offers a broad range of customizable cable harnesses and medical cable assemblies for patient monitoring systems. We provide complete assistance throughout your entire project—from cable design through product validation. Our custom cable-to-monitor connectors and cable harness systems provide patient comfort, excellent body ergonomics, and safety in high-risk environments. All of our cable assemblies for patient monitoring systems comply with RoHS standards. We provide custom solutions to match your specifications—whether your project is simple or complex.
Custom Patient Cables and Cable Harness Systems
Our design engineers will work with you to develop the perfect medical cable harness systems and cable-to-monitor connectors for your patient monitoring systems. Technology has allowed for many monitoring devices to be taken home for extended patient monitoring. Cable assemblies that are worn by patients for extended periods of time at home have unique requirements. They must be soft, flexible, and rugged. Minnesota Wire can choose the correct materials for effective at-home patient monitoring and patient comfort.
Advancements in the technology of monitoring patients can require unique approaches to connecting to patients. We work with our customers’ engineers to provide concepts, prototypes, and test data to develop the correct custom cable design for each application.
Connector Assemblies
Custom and Overmolded AED Connectors, PCBAs, and Simulator Pads
Even the most advanced manufacturing processes and custom-engineered designs are not enough to create the kind of high-quality products customers have come to expect from Minnesota Wire. To produce custom wire, custom cables, and custom cable assemblies that meet our customers’ high expectations, we use only the highest-quality materials.
Minnesota Wire manufactures a wide array of custom coil cords and coil cord assemblies. The conductor, shielding, insulation, and jacketing material all play a critical role in how the coil cord will perform. From soft (easy to extend) coil cords to rugged (must always retract) coil cords, we know the proper material choices.
PCBAs
Improvements in technology allow for more of the functionality of a device to be incorporated into the cable assemblies. Terminating, sealing, and overmolding PCBAs is challenging and requires unique materials, tool design, and processing. Minnesota Wire has the experience and capability to overmold PCBAs effectively.
We work with a wide range of materials, and will work with you to determine the best material choices for your product’s performance requirements. Numerous material options are available for every component of your custom product.
Drug Delivery Systems
Medical Cable Harness Systems and Wire for Drug Delivery and Patient Monitoring
Minnesota Wire offers a complete range of medical wire and medical cable harness system options for drug delivery systems and pain management applications. Our cable assemblies are widely used in medical dispensing systems, electro-stimulation machines, body-worn patient monitoring devices, and a variety of other medical products. Our products are USP/ISO 10993 Compliant.
If your project requires custom medical wires or a custom medical cable harness system for a drug delivery device, we have the knowledge and experience to provide the solution you need. For 50 years, we have specialized in cable and harness assemblies for the medical industry.

Automated External Defibrillator (AED)
Custom-Designed Automated External Defibrillator Connector
Minnesota Wire specializes in producing custom connectors and medical cables for use with Automated External Defibrillators (AEDs). We will custom engineer your medical connectors to match the unique specifications of your device.
Minnesota Wire’s custom connectors are specifically engineered for AEDs. Our connectors can be manufactured with either tinned copper or carbon-fiber conductors.
Minnesota Wire specializes in extruding carbon fiber. We are adept at designing, fabricating, and manufacturing custom connectors for AEDs. Whether you have a complete CAD blueprint for the medical connectors or cable that your project requires or just a basic concept, our engineering team will help you develop custom defibrillator leads that meet your exact requirements.
Custom Designed Defibrillator Leads
Carbon fiber is barely visible on x-ray and other imaging equipment. This eliminates the need to remove the electrode wires from the patient before imaging—providing an invaluable safeguard to the patient without negatively impacting results.
A typical Minnesota Wire AED cable contains 12,000 strands of conductive carbon fiber, yet weighs less than a conventional copper-conductor wire. Our carbon-fiber medical cables are flexible, lightweight, and offer small bend radii together with good low-signal transmission capabilities.
From the simplest designs to the most complex custom connectors, we have the production capabilities to deliver high-performance leads that meet defibrillator manufacturers’ requirements.
