Abstract
Abstract An apparatus for sealing a detachable implantable lead (30) to the housing of an implantable pulse generator (10). The pulse generator (10) has a molded in-line electrical connector (20) structured to create one or more electrical connections to the implantable lead. Sealing is accomplished by the use of grommets having pliant sealing rings located within the lumen. The grommets are placed within the lumen of the molded connector (20) at the external opening of the connector and between each of the individual in-line connector points (32, 36). The grommets are individually molded from silastic or other suitably pliant and body compatible material. The completed grommets are fitted into the molded connector into apertures which cause each grommet to be properly aligned with the lumen of the molded connector. The implantable lead has one or more in-line connector surfaces (32, 36) separated by suitable insulation (34). Upon insertion of the implantable lead into the molded connector each of the connector surfaces (32, 36) of the implantable lead is frictionally and electrically engaged with a corresponding electrical connection surface within the molded connector (20). Each of the insulating surfaces (34) between electrical connector surfaces of the implantable lead is frictionally engaged by one of the grommets.
