Abstract
Abstract A connector device for use in connecting to a electrode pacing electrode, paticularly for connecting a pacer to an electrode where such pacer and electrode are from different manufacturers and are normally not adapted for connection one to another. The connector has a coil which is dimensioned to tightly receive a pronged end of the electrode, the receiving end being further formed in a mating way to receive the electrode so as to prevent current leakage at the situs of connection. The connector is adapted to permit connection or disconnection only as the connector is rotated in one given direction relative to the electrode. In one of the embodiments, the connector is housed in the pacer.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
212 words
A connector adapted for connecting a pacer to an electrode, where said electrode has a proximal end with a conductor prong of predetermined diameter and a casing of predetermined geometry, said connector being adapted at its distal end to connect to said proximal electrode end and at its proximal end to a pacer terminal, said connector comprising: a. an inner coil extending through the length of said connector, said coil having at a distal portion an inside diameter just smaller than said conductor prong predetermined diameter, said coil further having several end turns of slightly larger diameter at said distal end, whereby entry of said electrode prong into said coil is facilitated; b. an inner casing surrounding said coil, said casing extending substantially the length of said connector; c. an outer casing around said inner casing at said connector distal end, said outer casing having a portion extending axially distal of the end of said coil, said extending portion having an opening with geometry substantially matching said predetermined electrode casing geometry; d. proximal end means at the proximal end of said connector for providing mechanical and electrical connection of said coil to a pacer terminal; and e. means for allowing rotation of said connector relative to said electrode in only one direction.
Claim 2
Dependent Claim
212 words
A connector adapted for connecting a pacer to an electrode, where said electrode has a proximal end with a conductor prong of predetermined diameter and a casing of predetermined geometry, said connector being adapted at its distal end to connect to said proximal electrode end and at its proximal end to a pacer terminal, said connector comprising: a. an inner coil extending through the length of said connector, said coil having at a distal portion an inside diameter just smaller than said conductor prong predetermined diameter, said coil further having several end turns of slightly larger diameter at said distal end, whereby entry of said electrode prong into said coil is facilitated; b. an inner casing surrounding said coil, said casing extending substantially the length of said connector; c. an outer casing around said inner casing at said connector distal end, said outer casing having a portion extending axially distal of the end of said coil, said extending portion having an opening with geometry substantially matching said predetermined electrode casing geometry; d. proximal end means at the proximal end of said connector for providing mechanical and electrical connection of said coil to a pacer terminal; and e. means for allowing rotation of said connector relative to said electrode in only one direction.
Claim 3
Dependent Claim
26 words
The connector as described in claim 1, wherein said inner casing has imprinted on the outside thereof rotation indicia, and said outer casing is substantially transparent.
Claim 4
Dependent Claim
128 words
A connector adapted for connecting a pacer to an electrode, where said electrode has a proximal end with a conductor prong of predetermined diameter and a casing of predetermined geometry, said connector being adapted at a first end to connect to said electrode proximal end and at its other end to a pacer terminal, comprising: a. conducting means for providing an electrical conduction path from said first connector end to said other connector end; b. mating means located at said first connector end for mating with said electrode proximal end; and c. said conducting means having an end portion at said first end adapted for electrical and mechanical engagement and disengagement of said conductor prong therewith only as said connector is rotated in direction relative to said electrode.
Claim 5
Dependent Claim
128 words
A connector adapted for connecting a pacer to an electrode, where said electrode has a proximal end with a conductor prong of predetermined diameter and a casing of predetermined geometry, said connector being adapted at a first end to connect to said electrode proximal end and at its other end to a pacer terminal, comprising: a. conducting means for providing an electrical conduction path from said first connector end to said other connector end; b. mating means located at said first connector end for mating with said electrode proximal end; and c. said conducting means having an end portion at said first end adapted for electrical and mechanical engagement and disengagement of said conductor prong therewith only as said connector is rotated in direction relative to said electrode.
Claim 6
Dependent Claim
51 words
The connector as described in claim 3, wherein said conducting means comprises an inner axially hollow conductor, and said conductor has an inside diameter at its distal end just smaller than said conductor prong diameter and several turns at the distal end thereof of slightly larger diameter than the other turns.
Claim 7
Dependent Claim
29 words
The connector as described in claim 4, wherein said connector is of a predetermined length, whereby when connected to said electrode it effectively adds said length to said electrode.
Claim 8
Dependent Claim
44 words
The connector as described in claim 3, and further in combination with a pacer for generating stimulus signals, said connector other end being housed in said pacer and said conducting means being connected at said connector other end to the output of said pacer.
