Abstract
Abstract The present invention is a torque handle for use in inserting and positioning a pacing lead and guide wire, such as within a coronary vein. The torque handle is a handle with a lumen extending therethrough. A first clamping arrangement is located on the handle and receives the guide wire therethrough. A second clamping arrangement is also located on the handle. The second clamping arrangement sized to receive the body of the lead therethrough. In use, the physician determines whether torque is to be transmitted along the lead, the guide wire or both. Torque is transmitted by clamping or loosening the designated clamping arrangement around the lead, the guide wire or both, and then rotating the handle. As the handle is rotated, torque is transmitted along the length of the clamped lead or guide wire or both.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
87 words
A torque handle for use in positioning a lead and guide wire arrangement used with a cardiac stimulating lead, said torque handle comprising: (a) a handle member with a lumen extending therethrough; (b) a first clamping arrangement on said handle member, said first clamping arrangement sized to receive said lead therethrough and being selectively clamped onto said lead; and (c) a second clamping arrangement on said handle member, said second clamping arrangement sized to receive said guide wire therethrough and being selectively clamped onto said guide wire.
Claim 2
Dependent Claim
87 words
A torque handle for use in positioning a lead and guide wire arrangement used with a cardiac stimulating lead, said torque handle comprising: (a) a handle member with a lumen extending therethrough; (b) a first clamping arrangement on said handle member, said first clamping arrangement sized to receive said lead therethrough and being selectively clamped onto said lead; and (c) a second clamping arrangement on said handle member, said second clamping arrangement sized to receive said guide wire therethrough and being selectively clamped onto said guide wire.
Claim 3
Dependent Claim
21 words
A torque handle of claim 1 wherein said first clamping arrangement is configured to receive a terminal end of said lead.
Claim 4
Dependent Claim
17 words
A torque handle of claim 1 wherein said first clamping arrangement comprises a chuck and corresponding collet.
Claim 5
Dependent Claim
17 words
A torque handle of claim 1 wherein said second clamping arrangement comprises a chuck and corresponding collet.
Claim 6
Dependent Claim
17 words
A torque handle of claim 3 wherein said second clamping arrangement comprises a chuck and corresponding collet.
Claim 7
Dependent Claim
241 words
A torque handle used in the insertion and positioning of a cardiac stimulating lead and guide wire, said torque handle comprising: (a) a handle with a lumen extending therethrough, said handle adapted to be affixed to a proximal end of said lead and guide wire, said lumen receiving said lead and guide wire therewithin, (b) a first threaded end on said handle member; (b) a second threaded end on said handle member; (c) a first collet inserted into said lumen and extending out from said first threaded end; (d) a first chuck surrounding said first threaded end and said first collet, said first chuck having a threaded internal bore for mating with said first threaded end of said handle member whereby said first chuck may be selectively rotated between a first position compressing said first collet about said guide wire and a second position not compressing said first collet about said guide wire; (e) a second collet inserted into said lumen on said second threaded end of said handle member and extending out from said threaded end; and (d) a second chuck surrounding said second threaded end and said second collet, said second chuck having a threaded internal bore for mating with said second threaded end of said handle member whereby said second chuck may be selectively rotated to a third position compressing said second collet about said lead and a fourth position not compressing said second collet about said lead.
Claim 8
Dependent Claim
241 words
A torque handle used in the insertion and positioning of a cardiac stimulating lead and guide wire, said torque handle comprising: (a) a handle with a lumen extending therethrough, said handle adapted to be affixed to a proximal end of said lead and guide wire, said lumen receiving said lead and guide wire therewithin, (b) a first threaded end on said handle member; (b) a second threaded end on said handle member; (c) a first collet inserted into said lumen and extending out from said first threaded end; (d) a first chuck surrounding said first threaded end and said first collet, said first chuck having a threaded internal bore for mating with said first threaded end of said handle member whereby said first chuck may be selectively rotated between a first position compressing said first collet about said guide wire and a second position not compressing said first collet about said guide wire; (e) a second collet inserted into said lumen on said second threaded end of said handle member and extending out from said threaded end; and (d) a second chuck surrounding said second threaded end and said second collet, said second chuck having a threaded internal bore for mating with said second threaded end of said handle member whereby said second chuck may be selectively rotated to a third position compressing said second collet about said lead and a fourth position not compressing said second collet about said lead.
