More Information
Summary:A medical electrical lead includes an insulative lead body extending from a distal region to a proximal region, a conductor disposed within the insulative lead body and extending from the proximal region to the distal region, an electrode disposed on the insulative lead body and in electrical contact with the conductor, and a fibrous matrix disposed on at least part of the electrode. The fibrous matrix includes fibers. The fibers include a polyvinylidene fluoride-based (PVDF-based) polymer and a crystal-modifying additive. The PVDF-based polymer includes an amorphous PVDF phase and a crystalline PVDF phase. The crystalline PVDF phase includes a beta form crystalline structure in an amount exceeding any other crystalline structure form in the crystalline PVDF phase.
