Abstract
A catheter suitable for percutaneous transluminal coronary angioplasty procedures and the like is provided. The catheter includes an annular balloon having an exterior wall, an interior wall and an inner longitudinal passageway defined by the interior wall. An elongated flexible tube extends into an interior compartment formed between the exterior and interior walls to pass fluid therebetween and inflate and deflate the balloon between a collapsed condition and an expanded condition. When in its expanded condition, the balloon engages a body vessel wall for dilating the body vessel, while simultaneously permitting perfusion of blood through the longitudinal passageway without need for an additional mechanism for pumping or channeling the blood.
