System for anchoring mid-lead electrode on an endocardial catheter lead
First Claim
1. An endocardial catheter lead comprising:
- an elongated insulative body member;
at least two conductors disposed within the insulative body member, including;
a first conductor connected at a distal end of the lead body member to a distal end electrode and at a proximal end of the body member to a first connector; and
a second conductor connected at a mid-lead portion of the body member to a mid-lead electrode and at the proximal end of the body member to a second connector; and
a plurality of fibrosis-anchoring openings defined in an exterior surface of the insulative body member and positioned along the insulative body member proximate the mid-lead electrode, including at least a first opening positioned proximal to the mid-lead electrode and a second opening positioned distal to the mid-lead electrode.

Abstract
A system for passively anchoring mid-lead electrodes on an endocardial catheter lead includes at least one fibrosis-anchoring opening positioned along the exterior surface of the catheter lead body proximal or distal to the mid-lead electrodes for passively securing the catheter lead against the interior wall of the heart. Within the fibrosis-anchoring openings a suitable material is provided for anchoring the catheter lead body to the heart wall by fibrosis. Preferably, the fibrosis-anchoring openings comprise at least a pair of openings positioned only partially around the exterior of the catheter lead body at locations both proximal and distal to the mid-lead electrodes, with the catheter lead body between the fibrosis-anchoring openings being preformed to bias the mid-lead electrodes against the heart wall.

11. A method of forming an endocardial catheter lead comprising the steps of:
-
(a) providing an elongated insulative body member; (b) inserting a conductor into the insulative body member and connecting the conductor to a mid-lead electrode at a mid-lead portion of the catheter body and to a connector at the proximal end of the catheter body; (c) creating a plurality of fibrosis-anchoring opening defined in an exterior surface of the insulative body member and positioned along the insulative body member proximate the mid-lead electrode and at least 2 cm from a distal end of the catheter body; and (d) disposing an anchoring material in each of the openings for securing the catheter lead against the interior wall of the heart by fibrosis. - View Dependent Claims (12)
