The invention relates to a catheter for the transvascular implantation of prosthetic heart valves, in particular including self-expanding anchorage supports (10), which allow a minimally invasive implantation of prosthetic heart valves. The aim of the invention is to reduce the risk to the patient during the implantation. To achieve this, according to the invention a prosthetic heart valve with anchorage supports is temporarily housed in a folded form in a cartridge-type unit (4) during the implantation. The cartridge-type unit can be fixed on the proximal end of a guide system (1), which includes a flexible region (9) that can be guided through the aorta. Actuating elements (2, 3) run through the interior of the hollow guide system, said elements permitting sections of the cartridge-type unit to be displaced radially about their longitudinal axis and/or laterally in a proximal direction, thus allowing individual sections of the anchorage support and the associated prosthetic heart valve to be sequentially released.

Catheter system for implantation of prosthetic heart valves

A medical device for treating a heart valve insufficiency, with an endoprosthesis which can be introduced into a patient's body and expanded to secure a heart valve prosthesis in the patient's aorta. In an embodiment, the endoprosthesis has a plurality of positioning arches configured to be positioned with respect to a patient's aorta and a plurality of retaining arches to support a heart valve prosthesis. The endoprosthesis includes a first collapsed mode during the process of introducing it into the patient's body and a second expanded mode when it is implanted.

Medical device for treating a heart valve insufficiency

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

Device for the implantation and fixation of prosthetic valves

A catheter is described for the transvascular implantation of prosthetic heart valves, e.g., including self-expanding anchorage supports, to reduce the risk to the patient during the implantation. Accordingly, a prosthetic heart valve with anchorage supports is temporarily housed in a folded form in a cartridge-type unit during the implantation. The cartridge-type unit can be fixed on the proximal end of a guide system, which includes a flexible region that can be guided through the aorta. Actuating elements run through the interior of the hollow guide system, permitting sections of the cartridge-type unit to be displaced radially about their longitudinal axis and/or laterally in a proximal direction, thus allowing individual sections of the anchorage support and the associated prosthetic heart valve to be sequentially released.

Medical device for treating a heart valve insufficency

The invention relates to a catheter for the transvasculur implantation of prosthetic heart valves, in particular comprising self-expanding anchorage supports (), which allow a minimally invasive implantation of prosthetic heart valves. The aim of the invention is to reduce the risk to the patient during the implantation. To achieve this, according to the invention a prosthetic heart valve comprising anchorage supports is temporarily housed in a folded form in a cartridge-type unit () riming the implantation. The cartridge-type unit can be fixed on the proximal end of a guide system (), which comprises a flexible region () that can be guided through the aorta. Actuating elements () run through the interior of the hollow guide system, said elements permitting sections of the cartridge-type unit to be displaced radially about their longitudinal axis and/or laterally in a proximal direction, thus allowing individual sections of the anchorage support and the associated prosthetic heart valve to be sequentially released.
