Implantable lead and method of making the same
First Claim
1. A method of manufacturing an implantable lead, the method comprising:
- providing a core including at least one longitudinal lumen;
providing a first coil having a first filarity about an outer circumferential surface of a first portion of the core;
providing a second coil having a second filarity different from the first filarity, about an outer circumferential surface of a second portion of the core longitudinally spaced from the first portion of the core;
providing a jacket about an outer circumferential surface of the first and second coils, wherein the jacket is formed of a reflowable material;
causing the material of the jacket to reflow through the first and second coils and bond to the core; and
causing the outer circumferential surface of at least one of the first and second coils to be exposed through the jacket.

Abstract
A method of manufacturing an implantable lead includes providing a core including at least one longitudinal lumen; providing a jacket comprising a reflowable material; positioning the core at least partially within the jacket; and, after positioning, applying heat to cause the material of the jacket to reflow and bond to the core. An implantable lead includes a core including at least one longitudinal lumen; and a jacket comprising a reflowable material. The core may be at least partially disposed within the jacket with the material of the jacket reflow-bonded to the core. The implantable lead may further include at least one lead component associated with at least one of the core and the jacket.

18. An implantable lead comprising:
-
a core having at least one lumen extending there through; a first coil having a first filarity extending about an outer circumferential surface of the core; a second coil having a second filarity different from the first filarity, extending about an outer circumferential surface of a second portion of the core longitudinally spaced from the first portion of the core; and a jacket reflowed about the outer circumferential surface of the core and about an outer circumferential surface of the first and second coils and impregnating the first coil and the second coil, wherein the outer circumferential surface of at least one of the first and second coils is exposed through the jacket and jacket material exists between individual filars of the coil. - View Dependent Claims (19, 20, 21, 22, 23, 24)
