Abstract:
A detachable connector for use with an implantable stimulator, the implantable stimulator having a case and a multiplicity of output contacts through which electrical connection with the implantable stimulator is made, the connector forming a proximal end of an implantable lead adapted to be detachably secured to the implantable stimulator, the implantable lead having a multiplicity of wire conductors embedded therein through which electrical contact with the implantable stimulator is to be made, said detachable connector comprising:an output bracket that forms part of the case of an implantable electrical stimulator, the output bracket having a cross section of a prescribed shape, wherein metal contacts are formed on each side of the cross section, and wherein each metal contact is electrically connected to electrical circuitry hermetically sealed within the case;a soft receiver made from a compliant material adapted to fit over the output bracket, the receiver having a channel therein with the same approximate cross sectional shape as that of the output bracket, the receiver including metal pins formed in side walls of the channel which are positioned to electrically contact a corresponding metal contact located in the output bracket when the receiver is fitted over the output bracket; anda U-shaped clamp adapted to fit over and compress the soft receiver against the output bracket, thereby maintaining the contact pins of the receiver in secure electrical contact with corresponding metal contacts of the output bracket, wherein the compliant walls of the receiver are deformed by the U-shaped clamp so as to provide electrical insulation and sealing between the various contact points included within the connector.
