Claim:
1. A method for occluding blood flow through an incision in a coronary wall of a human heart comprising inserting into said incision a medical closure device comprising: a cylinder element; a proximal expanded element that extends circumferentially around the entire circumference of said cylinder element, wherein said proximal expanded element is configured to adopt a reduced profile configuration upon inserting said proximal expanded element into a confined space and to resiliently readopt a high profile configuration upon exit from said confined space; and a distal expanded element that extends circumferentially around the entire circumference of said cylinder element, wherein said distal expanded element is configured to adopt a reduced profile configuration upon inserting said distal expanded element into a confined space and to resiliently readopt a high profile configuration upon exit from said confined space; wherein when deployed through the incision in the coronary wall of a human heart said distal expanded element forms a seal against the inner surface of the coronary wall, said proximal expanded element forms a seal against the outer surface of the coronary wall, and said medical closure device occludes blood flow through the incision without the need for thrombus formation; and wherein said medical closure device comprises one or more lumens through said cylinder element that allow access through the incision from the exterior of the heart to the interior of the heart.
