Vein valve cutting method |
摘要 |
A cutter for the in-situ cutting of valves within a vein. The cutter comprises a catheter having cutter fingers extending from its open distal end in an annular pattern. A sheath is selectively extensible over the fingers to shield them from inadvertent contact with the vein being treated. A fiberoptic viewer extends through the catheter to view through its open distal end.
