A catheter assembly provided with a wire arranged therein to form a loop extending from near the effective end of the catheter for bypassing an occlusion in a vein/artery. This loop consists of two wire ends, one of which wire ends extends through the catheter to the control end thereof, while the other wire end is attached thereto, in close proximity to the effective end of the catheter. By varying the relative position of the loop wire end extending from the control end and the control end, the size of the loop and the pushability thereof at the effective end of the catheter can be determined. In this manner, the occlusion can be removed with precise control by the physician using two hands. In addition, the catheter is formed not only for the loop wire end extending through the catheter, but also for incorporating a guide wire and/or for contrast fluids.

Catheter assembly for passing/bypassing an occlusion in veins/arteries, comprising a hollow catheter and a loop wire end arranged therein, said loop wire end extending from the operative end of the catheter, end being arranged in such a manner that it may be being pushed further outwardly or inwardly, wherein the rigidity of the catheter and the loop wire end are such that the moveable part of the loop wire end forms a separation and push away loop, said loop forming a bypass when advanced forward in the direction of an occlusion, said loop comprising another wire end, wherein the other loop wire end of said loop supports said catheter.
Method for passing/bypassing an occlusion in a vein/artery, comprising the introduction of a catheter to said occlusion, the advancement of a loop at the operative end of said catheter, comprising a loop wire end extending to the control end of said catheter, said loop being advanced in the direction of said occlusion and the passing/bypassing past said occlusion by means of the relative movement of loop wire and catheter by pushing aside and separating tissue, wherein the other end of said loop is supported by said catheter.
