A VENOUS VALVE CUTTER FOR THE INCISION OF VALVE LEAFLETS IN SITU

摘要

a blade (7) is driven by a shaft (6) is fixed to the center of the cutting edge (9) so that a portion of the blade extends on each side of the stem.a device (1) is increased to balance the blade (7) and a protective housing (10) so as to prevent the penetration of the device into the side of the connection.a catheter (14) follows the knife so as to bring the valve fluid into the vein to cause the closing of valves in front of the cutting device.the assembly is driven through a vein by a rod (5) with a rigidity sufficient to control the torsional direction of the blade, and obtain a commitment and a cupefficient valve leaflets.
