Tissue contact for satellite cardiac pacemaker
First Claim
1. An implantable cardiac system comprising:
- a master pacing unit operative to generate pacing pulses to be delivered to a portion of a patient'"'"'s heart;
at least one lead connected to the master pacing unit and configured for placement in electrical communication with a heart chamber; and
a satellite pacing unit remote from the master pacing unit and operative to apply pacing pulses to a different portion of the patient'"'"'s heart, said satellite pacing unit comprising;
a housing having a base portion;
an elongated member extending outwardly from said base portion for insertion into the patient'"'"'s heart tissue, wherein the elongated member comprises an electrode for carrying electrical current from the pacing unit to the patient'"'"'s heart; and
a gel-like material affixed to said base portion for placement into contact with the patient'"'"'s heart tissue, wherein said gel-like material is composed of an electrically conductive material to provide a complete electrical path for current generated from said elongated member.

Abstract
An implantable cardiac system has a master pacing unit and a remote satellite pacing unit. The master pacing unit is electrically coupled to a right side of a patient'"'"'s heart via a lead assembly. The satellite pacing unit is a leadless device mounted on the left side of the patient'"'"'s heart and is wirelessly controlled by the master pacing unit. The satellite pacing unit is affixed to the heart by one or more mounting members. The base of the satellite unit case has a gel-like material which facilitates adhesion of the pacing unit to the heart tissue. The gel-like material promotes tissue growth to hold the pacing unit in place on the heart. The gel-like material may be composed of polyvinlpyrrolidone and may contain a steroid, such as dimethyl sulfoxide (DMSO), or dexamethazone sodium phosphate.
