valve stent delivery device and valve stent graft

摘要

The present invention relates to a valve stent delivery device and a valve stent delivery device, which pertains to the medical field, more particularly a valve stent delivery device designed specifically for the combined endovascular treatment of aortic valve disease and of the ascending aorta segment, and the device allows endovascular navigability of the joint until the valve stent is specifically coupled for repair of injured ascending aorta segments and replacement of the calcified aortic valve, in addition to restoring anatomy and ensuring the consolidation of adequate blood flow in the region to be treated. The invention consists of a valve stent delivery device composed of several overlapping tubular segments, whereby by movement of the sheath tube (6) the proximal valve stent attached to the proximal region for balloon expansion (8) or self-expansion is released. a valve stent graft provided with a tubular body (100) coupled to a aortic valve (va).
