INTRALUMINAL IMPLANTATION DEVICE

摘要

The implantation device for treating damaged or diseased tissue within the region of the walls of hollow organs comprises a catheter and at least one securing means detachably received in a receptacle of the catheter. After the catheter has been placed in its appropriate position in the hollow organ, said securing means is implantable in the wall of the hollow organ with a. least one implantation segment of said means. The catheter may be provided with means for receiving a protective cover for covering larger diseased areas of the tissue, as well as with means for tensioning the hollow organ prior to and in the course of the implantation process. The securing means are nails, staples, screws or spirals having a length adapted to the thickness of the wall of the hollow organ to be treated. Such securing means are implanted in the vascular wall with the help of an element of the catheter, for example a pusher axially movably received in the catheter.
