A headerless pulse generator for an implantable tissue stimulator, such as a pacemaker, defibrillator or nerve stimulator, wherein the pulse generator has a significantly reduced size. The pulse generator is provided with a feed-through that couples directly to the terminal end of a lead. A connector of the terminal end of the lead, connects several conductors of the lead to the pulse generator without the need for a header assembly. The feed-through and connector are keyed to ensure proper orientation and, together, provide a means for locking the connector to the feed-through without the need for set screws.

[ What is claimed is:] [1.] An implantable device capable of electrically coupling an electrical lead having at least one conductor and suitable for stimulating tissue of a patient, said device comprising:(a) a housing having an opening extending from an external surface of said housing into an interior cavity formed therein, said cavity having an electronic circuit and power supply contained therein said electronic circuit and power supply generates a predetermined electrical pulse for stimulating tissue of a patient;(b) a non-conductive feed-through member engaged within the opening of said housing, thereby hermetically sealing said opening, said feed-through member having a base and electrical contacts embedded in the base of said feed-through member proximate said opening, wherein electrical conductors independently couple the electronic circuit contained within the cavity of said housing to corresponding electrical contacts; and(c) a connector member attached to a terminal end of an electrical lead, wherein said connector member has a shape conforming to said feed-through member and has lead electrical contacts coupled to corresponding lead conductors, wherein the lead electrical contacts couple with corresponding electrical contacts of said feed-through member.
