Abstract: Catheter assembly for passing an occlusion in a vessel, having a catheter hub; a hollow flexible shaft extending between the catheter hub and an open distal end; and a cutting wire provided inside the shaft, the cutting wire extending from the catheter hub to the distal end. The shaft has a cannula lumen with a cannula opening at the distal end, the cannula lumen being configured to guide a cannula. The catheter hub has a handle, which is configured to operate selectively in a cutting wire mode and in a cannula mode, and a blocking mechanism, configured to block the cannula from extending from the cannula opening while the cutting wire sticks out from the distal end.

Abstract: 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.

Abstract: Catheter assembly in which the catheter sleeve is provided with a flexible tip at its distal end for carrying out medical procedures. In order to be able to vary the position of the free end of said flexible tip, control means are present consisting of an actuating wire. According to the invention, said actuating wire is attached to the free end of the flexible tip and extends externally with respect to said flexible tip, in the direction of the catheter, and then passes through an opening into the inside of the catheter to the proximal end thereof.
