1. A method comprising:
- forming a lead assembly including coating an external portion of at least one electrode coil with a coating of fibrosis limiting material, wherein the electrode coil includes a first end, an opposite second end, and a length therebetween, and the coating of fibrosis limiting material extends past one or more of the first end portion and the second end portion without extending between contacting portions of adjacent windings of the electrode coil;
disposing the electrode coil over an electrode coil fitting and anchoring the fibrosis limiting material between the electrode coil and the electrode coil fitting;
coupling the at least one electrode coil with at least one conductor; and
disposing an insulative lead body over at least a portion of the at least one conductor and adjacent to the electrode coil and coating.

Abstract
Defibrillator lead designs and methods for manufacturing a lead having attachment between a fibrosis-limiting material covering, a shocking coil electrode, and an implantable lead body are disclosed herein. An electrode coil fitting is disposed within the shocking coil electrode. In an option, the fibrosis limiting material extends past the ends of the electrode coil, and is wrapped between the coil electrode and the electrode coil member.

12. A method comprising:
-
forming a coated electrode coil by applying a coating of fibrosis limiting material to an electrode coil, wherein the electrode coil includes a first end, an opposite second end, and a length therebetween, and wherein the coating of fibrosis limiting material includes a first end portion having a first end, and a second end portion having a second end opposite the first end portion, and wherein applying the coating of fibrosis limiting material to the electrode coil includes; disposing the fibrosis limiting material over an external surface of the electrode coil without extending between contacting portions of adjacent windings of the electrode coil, and wrapping the first end portion of the coating of fibrosis limiting material over the first end of the electrode coil so that the first end of the coating of fibrosis limiting material is disposed adjacent an inner surface of the electrode coil, and disposing the first end of the coated electrode coil over a first electrode coil fitting and anchoring the first end of the coating of fibrosis limiting material between the inner surface of the electrode coil and the first electrode coil fitting; coupling the at least one electrode coil with at least one conductor; and disposing an insulative lead body over at least a portion of the at least one conductor and adjacent to the electrode coil and the coating of fibrosis limiting material. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
