Patent ID: 7608086

Claim:
An anastomotic device comprising a slidingly woven tube, the woven tube defining a longitudinal axis and having each longitudinal end terminate in slidably engaging circumferential petals, the woven tube having an unactuated position of a generally cylindrical shape and an actuated position of a hollow rivet shape respectively for insertion through and for forming an anastomotic attachment defining a hollow opening between two proximate tissue walls at an anastomotic surgical site, wherein each petal comprises a petal tip flaring directionally outward away from the tissue walls when the anastomotic device is in the actuated position, and as said anastomotic device moves from the unactuated to the actuated position, the direction of the flare reduces sliding friction between moving petals, and when the anastomotic device is in the actuated position, the direction of the flare away from the tissue walls reduces pressure on tissue captured between the tip of each petal, wherein the woven tube comprises two strands, each strand of the two strands having unattached ends, wherein the unattached ends are flared in the same direction as the petal tips, wherein the petal tips are formed by bent portions of the wire strands such that each wire strand extends away from a respective first petal tip to form respective second and third petal tips after bending to form the respective first petal tip, wherein the unattached ends each terminate in a respective loop, wherein the loops are configured to position the unattached ends away from tissue contact when the anastomotic device is in the deployed position.
