摘要:
A system for implanting a heart valve prosthesis in a patient's heart includes a balloon expandable, tissue, stented heart valve and a transfemoral valve delivery device for delivering the stented heart valve to a target site in the patient's heart. The delivery device includes an inflation balloon module for expanding the stented heart valve prosthesis, markers on to assist in location of the delivery device at an appropriate location; and a streamlined cap.

摘要:
A device for implanting an expandable heart valve prosthesis at a valve annulus in a patient's heart includes an implantation device configured to extend from a first opening in the patient's body, through the patient's aorta, through a valve annulus, through an opening in a ventricle, and to exit through the patient's thoracic region. The device further includes a port having a hemostasis valve for providing access through the patient's thoracic region and into the ventricle and at least two interchangeable modules configured for delivery using the implantation device.
摘要:
A prosthetic heart valve includes at least one sealing member. The sealing member is adapted to conform to any surface irregularities found on the inner surface of the valve annulus, including any calcium deposits formed on the valve leaflets. The sealing member can be self-expanding or non-expanding. When deployed, the sealing member is adapted to create a blood tight seal between the prosthetic heart valve and the inner surface of the valve annulus thereby minimizing and/or eliminating perivalvular leakage at the implantation site.

An instrument for deploying a cardiac valve prosthesis, including a plurality of radially expandable portions, at an implantation site, includes a plurality of deployment elements each independently operable to obtain the radial expansion of a radially expandable portion of the valve prosthesis. The instrument includes a microprocessor configured to processes signals from one or more sensors and to optimize deployment of the valve prosthesis.

摘要:
A tool for facilitating access to the inside of a vessel and/or surgery on a vessel or an organ connected to the vessel. The vessel has a proximal end and a distal end, while the tool has a substantially cylindrical band and an arm. The band has a deployed configuration capable of opening the proximal portion of the vessel. The arm is connected to the band and has a deployed configuration capable of at least partially flattening the distal end of the vessel to improve the view inside the vessel. When deployed in a vessel, the tool holds the vessel in an open configuration and provides the physician with a surgical operating field, and the ability to pass a prosthesis through said tool and in a desired location within an organ.
摘要:
An instrument for positioning a cardiac valve prosthesis in a vessel includes a wire element to slidingly guide the valve prosthesis towards an implantation site and an expandable element coupled to the wire element. The expandable element is expandable in the vessel to position the wire element in association with the implantation site. A method for positioning a cardiac valve prosthesis includes securing a delivery instrument at an appropriate location at the implantation site and delivering the valve prosthesis to the implantation site using the delivery instrument.
