MEDICAL ELECTRICAL LEAD WITH PROXIMAL ARMORING
First Claim
1. A medical electrical lead configured to be coupled to a pulse generator in a cardiac rhythm management system, the lead comprising:
- a proximal connector configured to mechanically and electrically couple the lead to the pulse generator;
a flexible body extending distally from the connector, the body defining a proximal region, an intermediate region, and a distal region terminating in a distal tip;
an armoring layer disposed over the proximal region of the lead body and not over the distal region of the lead body, the armoring layer including a polymeric material having a lubricious outer surface configured to resist abrasion, and a reinforcing material disposed within the armoring layer;
at least one electrode coupled to the lead body in the distal region; and
at least one electrical conductor extending from the at least one electrode to the connector for electrically coupling the at least one electrode thereto.

Abstract
A medical electrical lead includes a flexible, insulative body defining a proximal region, an intermediate region, and a distal region. The proximal region is configured to be implanted at a subcutaneous implantation site, and is dimensioned to extend from an implantation location of the pulse generator to a location distal to a cardiovascular system entry site. The intermediate region is configured to extend distally from the proximal region to a location distal to a superior vena cava of a patient'"'"'s heart, and the distal region is configured to extend distally from the intermediate region within the patient'"'"'s heart. The lead further includes an armoring layer disposed on the lead body covering at least the proximal region.

20. A medical electrical lead configured to be coupled to a pulse generator in a cardiac rhythm management system, the lead comprising:
-
a proximal connector configured to mechanically and electrically couple the lead to the pulse generator; a flexible body extending distally from the connector, the body defining; a proximal region configured to be implanted substantially subcutaneously, and is dimensioned to extend from an implantation location of the pulse generator to a location distal to a cardiovascular system entry site; an intermediate region configured to extend distally from the proximal region to a location distal to a superior vena cava of a patient'"'"'s heart; and a distal region terminating in a distal tip, the distal region being configured to extend distally from the intermediate region within the patient'"'"'s heart; an armoring layer disposed over only the proximal and intermediate regions of the lead body, the armoring layer including a lubricious polymeric material and a reinforcing material embedded in the polymeric material, the armoring layer extending distally from the connector and terminating proximal to the intermediate region of the lead body; at least one electrode coupled to the lead body in the distal region; and at least one electrical conductor extending from the at least one electrode to the connector for electrically coupling the at least one electrode thereto.
