Abstract
Abstract The pacing lead assembly includes a multiconductor pacing lead including a plurality of wire conductors within a sheath of insulating material. A connector assembly surrounds the proximal end of the pacing lead and includes spaced apart metal bands on the sheath with each one of the wire conductors electrically connected to one of the metal bands. The connector assembly also includes insulating segments between the metal bands and a resilient conductive ring on each metal band adapted to make electrical connection with a metal ring in a socket in a pulse generator into which the connector assembly is inserted. The metal bands are spool-shaped with end flanges that provide means for retaining each resilient conductive ring in place on the metal band.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
151 words
A pacing lead assembly comprising a multiconductor pacing lead and a connector assembly surrounding the proximal end of said multiconductor pacing lead, said multiconductor pacing lead having said proximal end and a distal end and including at least two wire conductors within a sheath of insulating material, and said connector assembly including at least one metal band, means for electrically connecting one wire conductor to said one metal band, insulating means on either side of said metal band, a resilient conductive ring resiliently received on said band for electrically connecting said metal band to a metal ring in a socket in a pulse generator into which said connector assembly is inserted, and said band comprising means for retaining said resilient conductive ring in place on said metal band and for preventing said ring from being moved axially off of said metal band on relative movement between said connector and the socket.
Claim 2
Dependent Claim
151 words
A pacing lead assembly comprising a multiconductor pacing lead and a connector assembly surrounding the proximal end of said multiconductor pacing lead, said multiconductor pacing lead having said proximal end and a distal end and including at least two wire conductors within a sheath of insulating material, and said connector assembly including at least one metal band, means for electrically connecting one wire conductor to said one metal band, insulating means on either side of said metal band, a resilient conductive ring resiliently received on said band for electrically connecting said metal band to a metal ring in a socket in a pulse generator into which said connector assembly is inserted, and said band comprising means for retaining said resilient conductive ring in place on said metal band and for preventing said ring from being moved axially off of said metal band on relative movement between said connector and the socket.
Claim 3
Dependent Claim
43 words
The connector assembly of claim 1 wherein said insulating means include at least one insulator segment having at least one radially extending resilient flange which is adapted to be flexed when said connector assembly is inserted into the socket of the pulse generator.
Claim 4
Dependent Claim
16 words
The connector assembly of claim 1 wherein said conductive ring is made of conductive silicone elastomer.
Claim 5
Dependent Claim
17 words
The connector assembly of claim 1 wherein said conductive ring is made of a coiled garter spring.
Claim 6
Dependent Claim
35 words
The connector assembly of claim 1 wherein said conductive ring is made of woven metal fabric which is coiled into a cylinder and the cylinder is then welded at the ends to form a toroid.
Claim 7
Dependent Claim
34 words
The connector assembly of claim 1 wherein an insulator segment is provided at the proximal end of said connector assembly and has an axial passageway therethrough communicating with the interior of said pacing lead.
Claim 8
Dependent Claim
28 words
The connector assembly of claim 1 wherein each of said metal bands is spool-shaped and has a central cylindrical portion and end flanges which define said retaining means.
Claim 9
Dependent Claim
42 words
The connector assembly of claim 7 wherein each spool-shaped metal band has a radially extending slot therein for frictionally receiving the bare end of one of said wire conductors which extends through an opening in the sheath into said radially extending slot.
Claim 10
Dependent Claim
47 words
The connector assembly of claim 1 including two additional bands and two additional resilient conductive rings, each positioned on one of said additional metal bands, and wherein all of said bands are spaced from each other, and said insulating means insulate said metal bands from each other.
