Abstract
A method for inhibiting hyperplasia at an anastomotic junction of a vascular fistula or vascular graft comprises exposing the anastomotic junction to vibrational energy at a mechanical index and for a time sufficient to inhibit hyperplasia. Kits are described comprising the catheter or a probe suitable for performing the methods together with instructions for use setting forth the methods. The methods and kits are particularly suitable for treating anastomotic junctions formed to provide vascular access for hemodialysis, hemofiltration, and the like. The methods and kits are also suitable for treating other vascular grafts, such as those formed during cardiac bypass graft surgery, vascular repair, and the like.
