Revision and supplementation transplantation piece and aneurysm restoration manner

摘要

(57) Abstract This invention the distal end of the transplantation piece includes the revision and supplementation transplantation piece which possesses the means which draw with respect to portion of the open-ended mooring component, manner and the transplantation one system for aneurysm restoration are offered. Before the layout, the transplantation piece or the mooring component are not to be piled up in order to make the major diameter of the delivery system small. It draws to ideal, and means include the pulling strand which is jointed to the distal end of the transplantation piece, the distal end of the transplantation piece, has reached the point where it can be pulled the upper part of the proximal section of the mooring component. Continuing, expansion of the mooring component which happens, makes the transplantation piece which is piled up the nerve tube wall fit, designates the deviation blood current as minimum, installs the transplantation piece stably on the nerve inside of pipe. Stable installation means, touching to the mooring component, in order the transplantation piece furthermore to install stably in the mooring component, can be advanced alongside each pulling strand. In addition as for the transplantation piece, it can include the means in order to guide the 2nd open-ended mooring component to the proximal edge of the transplantation piece. Ideally, as for guide means the guide strand which is jointed to the proximal edge of the transplantation piece is included. The mooring component after that, until the transplantation piece is piled up with the 2nd mooring component, can be advanced alongside the guide strand. Expansion of the 2nd mooring component installs the proximal edge of the transplantation piece stably.
