Fischer finds success in medical applications

9 June 2010 Interconnection

Fischer Connectors recently achieved design wins in two innovative medical products.

Its secure, durable, lightweight connectors have been used in what is said to be the smallest heart-lung assist device, Maquet’s CardioHelp, while watertight, rugged, miniature connectors were selected for use in Ohio Willow Wood’s LimbLogic prosthesis.

CardioHelp provides an extracorporeal support for a patient’s circulation and respiration, and guarantees adequate gas exchange to prevent heart and/or lung failure. When designing this system, Maquet’s engineering team required products that facilitated the creation of a heart-lung assist system that is so light in weight and small that it can be carried by one person and compact enough to be used in a helicopter or vehicle. Fischer Connectors helped the company achieve the goal of simple and quick connecting of disposables.

With the requirement that the LimbLogic VS controller had to be sealed, watertight and leak proof, Fischer Connectors was selected to provide the connector and cable assembly technology for the product. When working to design LimbLogic VS, product engineers also wanted to eradicate the discomforts of past prosthetics. To achieve this, it was necessary to have a reliable and controllable vacuum suspension device. Product engineers wanted to eliminate both external tubing to the socket and bulky mounting. Key features they wanted to incorporate included easy inline mounting in a prosthesis, ‘set and forget’ intelligent monitoring of pressure, remote control operation, a waterproof controller and quiet operation.
