Abstract:
1. An implantable heart stimulator comprising: a pulse generator and an electrode lead connected thereto for delivering electrical stimulation pulses to a heart of a patient, said pulse generator having an electrically conductive housing, said housing comprising a connector header in which said electrode lead is mechanically and electrically connected; said electrode lead having a proximal portion which, after implantation of said electrode lead, is configured to extend substantially from the housing to a location situated beyond entry of the electrode lead into the venous system and before entry of the electrode lead into the superior vena cava, said proximal portion having an exterior with an electrically conductive surface; and a current source for supplying an infection control current between said housing and said electrically conductive surface of said proximal portion of said electrode lead for counteracting bacterial growth at least on an exterior of said housing, said connector header having an exterior surface that is entirely electrically conductive and is in a flow path of said infection control current.
