Artificial medical graft with a releasable retainer
First Claim
Patent Images
1. A graft system comprising:
- a tubular graft comprising a tubular connection portion which is initially radially relatively small and which is selectively radially enlargeable, the connection portion being configured to selectively resiliently radially enlarge from being radially relatively small; and
a releasable retainer configured to retain the connection portion radially relatively small until the retainer releases the connection portion, the retainer comprising a removable structure disposed at least part way around the connector portion, the removable structure comprising a C-shaped clip structure.

Abstract
A tubular artificial graft for attachment to a patient'"'"'s tubular body tissue has an initially radially relatively small connector structure adjacent each of its ends. The initial relatively small size of each connector structure facilitates insertion of that portion of the graft into the body tissue to which that connector structure is to make a connection. After a connector structure is properly positioned relative to the body tissue, the connector structure is radially enlarged to connect the graft to the body tissue. The connection is preferably both a mechanical and a fluid-tight connection.

8. A graft system comprising:
-
a tubular graft comprising a tubular connection portion which is initially radially relatively small and which is selectively radially enlargeable; a selectively radially enlargeable structure for selectively radially enlarging the connection portion, wherein the radially enlargeable structure is controlled via a control structure which passes through an aperture in a tubular side wall of the graft, and the radially enlargeable structure and the control structure are configured to be withdrawn via the aperture; and a structure configured to selectively close the aperture.
