Abstract
The present invention is a method and device for harvesting a vessel. The vessel harvester comprises an internal stenting catheter with proximal and distal ends, a sheath catheter with proximal and distal ends, and a cylindrical cutting tube that is attachable to the distal end of the sheath catheter. The vessel harvester is used to harvest vesseal such as the greater and lesser saphenous veins, the basilic vein, the cephalic vein, and the radial artery.
Claims7
A vessel harvesting device comprising a stenting catheter, a sheath catheter with proximal and distal ends, and a cutting tube that is fixedly connected to the distal end of the sheath catheter, wherein the sheath catheter is inside of the cutting tube and the cutting tube has a cutting edge facing in a proximal direction relative to the distal end of the sheath catheter, wherein the sheath catheter further comprises a peel-away catheter.
A vessel harvesting device comprising a stenting catheter, a sheath catheter with proximal and distal ends, and a cutting tube that is fixedly connected to the distal end of the sheath catheter, wherein the sheath catheter is inside of the cutting tube wherein the cuffing tube has a bevelled cutting edge that is bevelled radially outward and that faces in a proximal direction relative to the distal end of the sheath catheter.
A vessel harvesting device comprising a stenting catheter, a sheath catheter with proximal and distal ends, and a cutting tube that is connectable to the distal end of the sheath catheter, wherein the sheath catheter has connecting prongs at its distal end and the cutting tube has corresponding connecting ports at its distal end for connecting the cutting tube to the sheath catheter.
A vessel harvesting device comprising a stenting catheter, a sheath catheter with proximal and distal ends, and a cutting tube that is connectable to the distal end of the sheath catheter, further comprising a plurality of guide wires for guiding the cutting tube during vessel harvesting.
