Abstract
Devices and methods are disclosed for the percutaneous administration of a composition to a desired in vivo location. The composition comprises a biologically active substance and a pharmaceutically acceptable carrier. The pharmaceutically acceptable carrier is preferably non-solid and a polymer, which is preferably capable of being transformed into a gel, thus allowing timed-released delivery of the substance. A preferred use for this invention is to provide local delivery of biologically active substances for the prevention of restenosis following angioplasty or other blood vessel injury.
