Endovascular prosthesis with suture holder
An endovascular prosthesis has a prosthesis body that is sized and configured for introduction into a blood vessel lumen. The prosthesis body has a wall that defines an interior passage for blood. One or more connectors are distributed about the wall. A fastener is carried by at least one of the connectors. The fastener is sized and configured for advancement through the connector into tissue in the blood vessel lumen.
1. An endovascular prosthesis system comprising
a prosthesis body sized and configured for introduction into a blood vessel lumen and including a wall defining an interior passage for blood,
means for radially expanding the wall of the prosthetic body into contact with the blood vessel lumen,
a plurality of connectors attached to the wall in a circumferentially spaced distribution, and
a tissue piercing spiral suture carried by each of the connectors, each tissue piercing spiral suture including a sharpened penetrating end that pierces tissue in response to rotation of the tissue piercing spiral suture,
a plurality of semi-flexible cables, each semi-flexible cable including a distal end releasably connected to one of the tissue piercing spiral sutures carried by one of the connectors and a proximal end that extends to a remote location outside the blood vessel lumen, and
an external rotary driver sized and configured to be coupled to the proximal end of each semi-flexible cable to rotate the semi-flexible cable and thereby rotate the tissue piercing spiral suture carried by the respective connector to pierce tissue and advance through the connector into tissue in the blood vessel lumen,
each connector further including a base comprising a tissue penetration stop for the tissue piercing spiral suture.
2. A prosthesis system according to claim 1
wherein the means for radially expanding the wall of the prosthesis body into contact with tissue in the blood vessel lumen includes thermal expansion.
3. A prosthesis system according to claim 1
wherein the means for radially expanding the wall of the prosthesis body into contact with tissue in the blood vessel lumen includes an expandable body expandable within the prosthesis body.
