Device for the implantation and fixation of prosthetic valves
First Claim
1. A device for the transvascular implantation and fixation of prosthetic heart valves having a self-expanding heart valve stent introducible through a blood vessel of a patient which exhibits a prosthetic heart valve at its proximal end, wherein the device furthermore comprises a self-expanding positioning stent introducible into the pockets of a patient'"'"'s diseased heart valve which is configured separately from the heart valve stent, and the positioning stent and the heart valve stent are configured so as to respectively interact in their expanded states such that the heart valve stent is held by the positioning stent in a position within the ventricular outflow tract and the arteries close to the patient'"'"'s heart predefinable by the positioning stent relative the heart valve.

Abstract
A device for the transvascular implantation and fixation of prosthetic heart valves having a self-expanding heart valve stent (10) with a prosthetic heart valve (11) at its proximal end is introducible into a patient'"'"'s main artery. With the objective of optimizing such a device to the extent that the prosthetic heart valve (11) can be implanted into a patient in a minimally-invasive procedure, to ensure optimal positioning accuracy of the prosthesis (11) in the patient'"'"'s ventricle, the device includes a self-expanding positioning stent (20) introducible into an aortic valve positioned within a patient. The positioning stent is configured separately from the heart valve stent (10) so that the two stents respectively interact in their expanded states such that the heart valve stent (10) is held by the positioning stent (20) in a position in the patient'"'"'s aorta relative the heart valve predefinable by the positioning stent (20).
