DEVICE FOR THE IMPLANTATION AND FIXING OF HEART VALVE PROSTHESES

摘要

The invention relates to a device for the implantation and fixing of heart valve prostheses with a heart valve prosthesis (4) fixed to a self-expanding locating support (1). The aim of the invention is to implant heart valve prostheses in a minimally-invasive manner with increased positional accuracy in a heart chamber of a patient. Said aim is achieved, whereby a self-expanding locating support is housed in a cartridge (6) which may be connected to a catheter in a folded form. Support hoops (2) are embodied on the proximal side of the locating support which may be introduced into the pockets of the heart valve of a patient. The release of the support hoops from the cartridge is achieved by means of a first given movement of the cartridge. Further elements of the locating support with the heart valve prosthesis are released to give complete expansion and location by means of at least one further movement of the cartridge and/or the catheter.
