Abstract
A header adapter which is a separately molded part and which is designed to be secured to receiving portions of the header and pulse generator case of an implantable cardiac stimulation device, such as a pacemaker or implantable cardioverter-defibrillator, in order to provide a different lead connector port configuration than that provided by the header of the device. The header adapter has a plurality of adapter lead connector ports and a plurality of lead connectors affixed to a rear portion (mounting side) thereof. The lead connectors extend outwardly from the rear portion of the header adapter, and are insertable into corresponding lead connector ports of the header of the implantable cardiac stimulation device to which the header adapter is to be secured. At least one of the plurality of adapter lead connector ports is of a different size than any of the header lead connector ports of the device to which the header adapter is to be secured, and/or the number of adapter lead connector ports is different (greater or less than) the number of header lead connector ports of the device to which the header adapter is to be secured. Two or more leads inserted into the header adapter lead connector ports can be electrically connected to the same lead connector and/or one or more of the leads inserted into a header adapter lead connector port(s) can each be electrically connected to two or more of the lead connectors. Further, one or more of the lead connectors can be an electrically inactive 'dummy' lead connector. The header adapter is preferably made of a transparent or translucent polymeric or other electrically insulative, biocompatible material, such as an epoxy resin or a thermoplastic elastomer. The invention also relates to an implantable cardiac stimulation device to which the header adapter is secured.
