    Abstract: The present invention relates generally to the materials and methods for improving the wettability of an implantable medical device. More specifically, the invention relates to devices and methods for coating at least a portion of a medical device to improve wettability and reduce electrical impedance. Given the challenges of maintaining consistent and predictable electrical characteristics as implantable medical devices become smaller in size, there remains a continual need to improve wettability in an effort to improve medical outcomes.

    Abstract: 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.

    Abstract: A block copolymer including a plurality of polymeric chains and a plurality of cross-linking compound residues linking together the plurality of polymeric chains. The plurality of polymeric chains forms a plurality of hard domains and a plurality of soft domains. Each polymeric chain includes a plurality of soft segments and a plurality of hard segments. The plurality of soft segments includes a polyisobutylene diol or diamine residue. The plurality of soft segments forms the plurality of soft domains. The plurality of hard segments including a diisocyanate residue. The plurality of hard segments forms the plurality of hard domains. The cross-linking compound residues link together the hard segments of the plurality of polymeric chains.

    Abstract: A method for making a polyisobutylene diol from a polyisobutylene diallyl. The method includes hydroborating the polyisobutylene diallyl to produce a polyisobutylene dialkyl borane, and oxidizing the polyisobutylene dialkyl borane to form the polyisobutylene diol. The polyisobutylene diallyl is hydroborated by combining in situ the polyisobutylene diallyl with a borane-coordinating solvent, an alkaline metal salt of borohydride, and an acid. The alkaline metal salt of borohydride is combined with the polyisobutylene diallyl before the acid is combined with the polyisobutylene diallyl.
