Abstract
Implementations described and claimed herein provide an implantable lead optimized for an implant environment and methods of manufacturing such implantable leads. The implantable lead includes an insulation layer having one or more transitions along a length of the insulation layer from a proximal end to a distal end. Each of the transitions is a seamless change from a section of the insulation layer having a set of performance characteristics to another section of the insulation layer having a different set of performance characteristics.
Claims35
An implantable lead optimized for an implant environment, the implantable lead comprising:
- an insulation layer having one or more transitions along a length of the insulation layer from a proximal end to a distal end, each of the transitions being a seamless change from a section of the insulation layer having a set of performance characteristics to another section of the insulation layer having a different set of performance characteristics;
- wherein a first section of the insulation layer is disposed at a distal portion of the insulation layer and a second section of the insulation layer is disposed proximal to the first section of the insulation layer, wherein the first section of the insulation layer has a first set of performance characteristics including a first wall thickness and the second section of the insulation layer has a second set of performance characteristics including a second wall thickness, and wherein the second wall thickness is greater than the first wall thickness.

An implantable lead insulation layer comprising:
- a first section having a first set of performance characteristics;
- a second section having a second set of performance characteristics that is different from the first set of performance characteristics;
- and
- a first transition between the first section and the second section, the first transition preventing the first set of performance characteristics from compromising the second set of set of performance characteristics.
A method for manufacturing an implantable lead optimized for an implant environment, the method comprising:
- obtaining a plurality of insulation layer sections, each insulation layer section having a set of performance characteristics based on a local environment in which the insulation layer section is to be implanted;
- positioning the plurality of insulation layer sections relative to each other;
- and
- fusing the plurality of insulation layer sections together such that one or more transitions are formed along a length of a composite insulation layer.
The method of 26, wherein the plurality of insulation layer sections each include a thermoset material that is not capable of melt-reflow.
