ELECTRODEPOSITION COATING FOR MEDICAL DEVICES

摘要

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.

主权项

1. A method for coating a scoring element of a balloon catheter, the method comprising:
introducing a coating solution comprising at least one polar pharmaceutical agent dissolved in a solvent into a coating apparatus, the coating apparatus comprising at least one electrically conductive scoring element functionally coupled to the coating apparatus; applying an electrical current to the coating apparatus to produce a charged scoring element that attracts the polar pharmaceutical agent to the charged scoring element, thereby depositing the polar pharmaceutical agent onto the charged scoring element.
