Abstract
A balloon catheter device for treating an obstructing material within a vascular conduit or other body passageway. The device comprises an elongate catheter body extending between a proximal end and a distal end. A high compliance balloon and a spaced apart angioplasty balloon are coaxially disposed along the distal end. The catheter device includes a plurality of longitudinal lumens which extend along the catheter body from the proximal end. At least one of the lumens has a cross section which is non circular and is configured, in conjunction with the other lumens to provide a maximum total lumen cross sectional area within a minimum diameter catheter body.
