Abstract
An implantable medical device includes a first component including a first material, a second component including a second material, and a fiber matrix including a plurality of fibers. The fiber matrix joins the first component to the second component. The fiber matrix includes a first a first portion connected to the first component, and a second portion connected to the second component. The first portion of the fiber matrix is interpenetrated with, and mechanically fixed to, the first material. The first portion of the fiber matrix directly contacts the first material.

A method for joining a first component and a second component of an implantable medical device, the method comprising:
- interpenetrating a first portion of a fiber matrix, including a plurality of electro-spun or electrosprayed fibers, within a first material, the first material being a silicone polymer in a liquid state;
- forming the first component by solidifying the first material, wherein the first portion of the fiber matrix is mechanically fixed within the silicone polymer of the first component and a second portion of the fiber matrix projects from the first component;
- and
- connecting the second portion of the fiber matrix to the second component to join the first component to the second component.
A method for joining a first component, including a silicone polymer, and a second component, including a polyurethane polymer, of an implantable medical device, the method comprising:
- electro-spinning a first portion of a plurality of fibers directly into a the silicone polymer, the silicone polymer being in a liquid state;
- solidifying the silicone polymer to form the first component, wherein the first portion of the plurality of fibers is mechanically fixed within the first component and a second portion of the plurality of fibers projects from the first component;
- and
- connecting the second portion of the plurality of fibers to the second component to join the first component to the second component.
