DEVICES FOR TRANSCATHETER PROSTHETIC HEART VALVE IMPLANTATION AND ACCESS CLOSURE
First Claim
1. Apparatus for delivering instrumentation into a patient'"'"'s circulatory system comprising:
- a tubular member for passing through a wall of the circulatory system; and
a valve disposed inside the tubular member for substantially preventing blood from leaving the circulatory system via the tubular member, the valve being configured to allow instrumentation to pass through the tubular member and the valve to enter the circulatory system.

Abstract
Apparatus for use in conjunction with implanting a collapsible and re-expandable prosthetic heart valve in a patient by means that are less invasive than traditional open-chest, open-heart surgery. The apparatus may include a one-way valve for preventing blood from escaping from the patient'"'"'s circulatory system when that system is entered in order to get the prosthetic heart valve into that system. The apparatus may include various forms of cutters for gaining access to the patient'"'"'s circulatory system. The apparatus may include various forms of devices for quickly closing the access to the patient'"'"'s circulatory system after the prosthetic heart valve has been implanted.

10. Apparatus for closing an aperture through a wall of a patient'"'"'s circulatory system comprising:
a structure that is collapsible for delivery into the patient and part way through the aperture via a tube, the structure being at least partly resiliently biased to expand radially outwardly relative to the aperture when released from confinement by the tube, the structure including a first portion that is resiliently biased to expand radially outwardly relative to the aperture inside the circulatory system, a second portion that is resiliently biased to expand radially outwardly relative to the aperture outside the circulatory system, and a third portion that connects the first and second portions and that is configured for disposition in the aperture. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
