Abstract

A thrombectomy removal kit having: (a) a catheter balloon assembly having proximal and distal ends including a first catheter carrying a remotely inflatable occlusion balloon and a second catheter carrying a mechanical device for removing a clot; (b) a balloon-collared sheath having a collar sheath with proximal and distal ends, the collar sheath having an open interior, and a sealing valve for sealing the interior of the collar sheath, and inflatable collar balloon, disposed on the exterior distal end of said collar sheath; and (c) a suction module, having a suction sheath attachable to a suction device, the suction sheath having proximal and distal ends, the suction sheath having an open interior, and sized to be inserted in a vein.

Claims

1. A thrombectomy removal kit comprising:

(a) a catheter assembly having proximal and distal ends comprising a first catheter having proximal and distal ends and carrying a remotely expandable occlusion device near said first catheter distal end and a second catheter having proximal and distal ends and carrying a remotely expandable means for mechanically moving a clot near said second catheter distal end, said first catheter slidable with respect to said second catheter;

(b) a balloon-collared sheath comprising a collar sheath having proximal and distal ends, said collar sheath having an open interior, and a sealing valve disposed in said interior of said collar sheath, and an inflatable collar balloon, disposed on the exterior of said collar sheath; and

(c) a suction module, comprising a suction sheath attachable to a suction device, said suction sheath having proximal and distal ends, said suction sheath having an open interior, and sized to be inserted in a human patient'"'"'s vessel.

2. The thrombectomy removal kit of claim 1 wherein said expandable means for mechanically moving a clot is a remotely inflatable thrombectomy balloon positioned on the exterior surface of said second catheter.

3. The thrombectomy removal kit of claim 2 wherein said thrombectomy balloon has at least one rib disposed on an exterior surface of said second balloon.

4. The thrombectomy removal kit of claim 1 wherein said second catheter has a hollow interior portion, and said first catheter and said second catheter are sized so that said first catheter distal end is slidable in the hollow interior portion of said second catheter, in a nested relationship.

5. The thrombectomy removal kit of claim 1 wherein said suction module further comprises a side channel in fluid communication with said interior of said suction sheath, and a clot fragmentation means is slidably disposed in said side channel, said clot fragmentation means movable into said suction sheath interior.

6. The thrombectomy removal kit of claim 5 wherein said clot fragmentation means comprises a brush, coil, or screw.

7. The thrombectomy removal kit of claim 1 wherein said expandable means for mechanically moving a clot comprises a cone.

8. The thrombectomy removal kit of claim 1 wherein said expandable occlusion device of said first catheter comprises an occlusion balloon.

9. The thrombectomy removal kit of claim 1 wherein said second catheter has a hollow interior portion, and said first catheter and said second catheter are sized so that said first catheter distal end is slidable in the hollow interior portion of said second catheter distal end, in a nested relationship, and said nested first and second catheters distal ends are slidable in said open interior of said balloon collar sheath.
