Clot removal system and methods of use
A system for removing a blood clot includes a first catheter having an inner sheath, the sheath having an interior passage and a plurality of apertures for delivering a drug, and a second catheter having a hollow outer sheath sized to fit over the inner sheath, the second catheter having an agitating element to break apart or loosen the blood clot.
1 . A device for removing a blood clot, the device extending between a proximal end and a distal end, the device comprising:
a central sheath having a sidewall and defining a plurality of apertures in the sidewall;
a first balloon adjacent the distal end;
a second balloon adjacent the proximal end; and
at least two undulating wires disposed between the first balloon and the second balloon, the at least two undulating wires being coupled at one end to the central sheath, each of the at least two undulating wires having a free proximal end, and each of the at least two undulating wires having a plurality of peaks and valleys and being actuatable by manipulation of each free proximal end.
2 . The device of claim 1 , wherein each free proximal end extends through the central sheath out of the proximal end for direct manipulation by a physician.
3 . The device of claim 1 , wherein the at least two undulating wires are evenly distributed about a circumference of the central sheath.
4 . The device of claim 1 , wherein the plurality of apertures are disposed between ends of each of the at least two undulating wires.
5 . The device of claim 1 , wherein each of the at least two undulating wires is disposed to one side of the central sheath.
6 . The device of claim 1 , wherein each of the at least two undulating wires does not wrap around the central sheath.
7 . The device of claim 1 , wherein the at least two undulating wires comprise a shape memory material.
