ABSTRACT:
A catheter sleeve includes a radially expansible distal region having a plurality of axial blood perfusion lumens or channels formed thereon. The catheter sleeve may be introduced over a conventional angioplasty balloon catheter with the expansible region lying over the balloon. When the balloon of the angioplasty catheter is expanded, the perfusion lumens will provide a flow path for blood around the expanded balloon. Optionally, the catheter sleeve may further include drug infusion lumens over the radially expansible region. In this way, drugs can be delivered over prolonged periods while the underlying angioplasty balloon is inflated and blood flows through the lumens or channels to perfuse the distal myocardium.
