Abstract
A drug delivery catheter assembly, including an expandable, porous outer membrane that is insertable into a blood vessel and positioned adjacent a stenotic atherosclerotic lesion on the interior wall of the blood vessel. The membrane is expanded into contact with the lesion, either mechanically or hydraulically. After the membrane is expanded, a drug-containing liquid is caused to flow into the membrane and through the pores in the membrane into contact with the lesion.
