Catheter for percutaneous surgery of blood vessels and organs using radiant energy.

摘要: A cardiac catheter useful for performing percutaneous valvotomy using a laser beam contains positioning mechanism with at least one pair of wires disposed essentially in the longitudinal direction catheter. In region distal end catheter, (2, 3) can be resiliently flexed from basic position which they adhere closely to surface form two intersecting, axially offset, convex wire arcs projecting radially above intersection, an indent (25) positive anchorage on heart valve. fibre optic transmission is connected 3). The therefore positioned beating without interrupting blood flow such way that accurately focused site action
