venous segments retracting equipment for use during e.g. phlebectomy, has projections acting as stops integrated to carrier element and ensuring invagination function, where one of stop stops sliding of venous segment on equipment

摘要

The equipment has a pair of projections (a, b) acting as stops integrated to a carrier element and ensuring an invagination function, where the equipment is constituted of catheter or rod whose length is sufficient for permitting catheterization of vessel to be extracted. One of the stops is placed against a projection (c) placed at the end of the equipment for rigidifying the carrier element. Another stop stops the sliding of the venous segment on the equipment.
