| 摘要 |
There is provided a catheter for providing a delivery substance to a bifurcated vessel, and isolating a treatment zone within the bifurcation. The catheter includes a proximal shaft and a first and second distal shaft positioned within the proximal shaft. The proximal shaft has a proximal occlusion element at a distal end thereof, the first distal shaft has a first distal occlusion element at a distal end thereof, and the second distal shaft has a second distal occlusion element at a distal end thereof. When the proximal occlusion element, and the first and second distal occlusion elements are deployed, a treatment zone is defined, and a delivery substance may be introduced into the treatment zone via the proximal shaft. |

1. A catheter for delivery of agents to a bifurcated vessel, the catheter comprising:
a proximal shaft having
a proximal shaft proximal end,a proximal shaft distal end,a proximal shaft outer wall extending from said proximal shaft proximal end to said proximal shaft distal end, said proximal shaft outer wall defining a proximal shaft lumen, anda proximal occlusion element positioned at said proximal shaft distal end; a first distal shaft positioned within said proximal shaft lumen, said first distal shaft having
a first distal shaft proximal end,a first distal shaft distal end,a first distal shaft outer wall extending from said first distal shaft proximal end to said first distal shaft distal end, anda first distal occlusion element positioned at said first distal shaft distal end; and a second distal shaft positioned within said proximal shaft lumen alongside said first distal shaft, said second distal shaft having
a second distal shaft proximal end,a second distal shaft distal end,a second distal shaft outer wall extending from said second distal shaft proximal end to said second distal shaft distal end, anda second distal occlusion element positioned at said second distal shaft distal end. |
