SYSTEM FOR INSERTION AND RELEASE OF A SELF-EXPANDING STENT AND METHOD FOR SAME

摘要

System for insertion of a compressed, self-expansible stent into in particular a blood vessel and for release of the stent in particular in the blood vessel, comprising a catheter with an inner tube, a middle tube and an outer tube, wherein the middle tube extends through the outer tube, and the inner tube extends through the middle tube, wherein the compressed stent, in a distal end portion of the catheter, is arranged radially compressed between the inner tube and the outer tube, running radially around the inner tube, and the middle tube ends distally at the proximal end of the stent, wherein, in order to release the stent, the outer tube is displaceable in the proximal direction and the middle tube in the distal direction, in such a way that the distal end of the stent maintains its intended position during the release.
