Of Course Medical Devices Need Wires and Cables

As the advancement of medical technology continues, it is important to note that none could have been possible without advancements in the signaling, control and power system interconnect components, including wiring and cabling. Historically, such components were often overlooked until late in the design process causing undesired results, delay in launch or a redesign of device systems. However, companies with a robust product development process include interconnect considerations early in product development.


Unlike traditional wires and cables, those used in medical devices must be flexible and able to withstand repeated flexing. They are also regulated under strict guidelines due to safety requirements and, depending on device type, the potential for patient contact of varying type and duration. These wire and cable need to function flawlessly after repeated sterilization processes including autoclave, gamma, and ethylene oxide, as well regular exposure to disinfectant wipes, liquids and aerosols.


Selection of jacket, sometimes referred to as the outer sheath, is based on the requirements of the application. For example, EKG leads will have a jacket, insulation, or tape-shield laminate that differs from those used in endoscopes or laparoscopes. While some connections may require increased flexibility, others may require a specialized material that can resist the corrosive nature of sterilization.  Further consideration is based on the method(s) of sterilization the cable will undergo and the expected number of sterilization cycles during the intended life of the cable.  Have any projects needing wire or cable solutions? Let Alpha Wire help you find the right product for your application.
