| 摘要 |
<p>This invention is a balloon catheter device (10) for treating an obstructing material within a vascular conduit or other body passageway (12). The balloon catheter device (10) comprises a catheter body (20) extending between a proximal end (24), and a distal end (26). A high compliance balloon (46), and a spaced apart angioplasty balloon (50) are coaxially disposed along the distal end (26). The balloon catheter device (10) includes a plurality of longitudinal lumens (28a-28d) which extend along the catheter body (20) from the proximal end (24). At least one of the lumens has a cross section which is non circular, and is configured, in conjuction with the other lumens to provide a maximum total lumen cross-sectional area within a minimum diameter catheter body (20).</p> |
