The present invention is directed towards an electrodepositable coating composition comprising a polyfarnesene polymer and an ionic salt group-containing film-forming polymer. Also disclosed are methods of coating a substrate using the electrodepositable coating composition, coatings derived from the electrodepositable coating composition, and substrates coated with the coatings derived from the electrodepositable coating composition.

The present disclosure relates generally to coating medical devices. In particular, the present disclosure provides materials and methods for coating a portion of a balloon catheter with a pharmaceutical agent using electrodeposition techniques. Although angioplasty and stenting can be effective methods for treating vascular occlusions, restenosis remains a pervasiveness problem. Therefore, coating portions of a balloon catheter with a pharmaceutical agent that inhibits restenosis can reduce the likelihood of restenosis.
