Abstract

An implantable medical electrical lead having a lead body including a stranded or cabled conductor extending therein and an electrical connector mounted to a proximal end of the lead body and coupled to the stranded or cabled conductor and having a fabric tube molded into a proximal portion of the lead body adjacent the electrical connector. The fabric may be a polyester mesh formed or rolled into a tube and is preferably molded into the proximal portion of said lead body adjacent its exterior surface. The proximal portion of the lead body may be fabricated of silicone rubber or polyurethane.

Claims

1. An implantable medical electrical lead comprising:

an elongated insulative lead body;

a stranded or cabled conductor extending within said lead body;

an electrical connector mounted to a proximal end of said lead body and coupled to said conductor; and

a fabric tube molded into a proximal portion of said lead body adjacent said electrical connector.

2. A lead according to claim 1 wherein said fabric comprises a polyester mesh.

3. A lead according to claim 1 wherein said tube of fabric is a sheet of polyester mesh rolled into a tube.

4. A lead according to claim 1 or claim 2 wherein said tube is molded into said proximal portion of said lead body adjacent an exterior surface of said portion.

5. A lead according to claim 1 or claim 2 wherein said tube is molded into said proximal portion of said lead body at an exterior surface of said portion.

6. A lead according to claim 1 or claim 2 wherein said tube of fabric is a sheet of said fabric rolled into a tube.

7. A lead according to claim 1 or claim 2 wherein said proximal portion of said lead body is fabricated of silicone rubber or polyurethane.
