Abstract
Systems and methods introduce and deploy prosthesis into a blood vessel or hollow body organ by intra-vascular access. The prosthesis is secured in place by fasteners which are implanted by an applier that is also deployed by intra-vascular access. The applier is configured to permit controlled, selective release of the fastener in a step that is independent of the step of implantation.
Claims17
An assembly for applying an implantation force to a fastener sized and configured for implantation in tissue in response to the implantation force, the assembly comprising:
- a tool body;
- a driven member carried by the tool body and being operable to apply the implantation force, the driven member comprising a drive actuator to operate the driven member;
- and
- a mechanism comprising hinged gripping jaws coupled to the driven member such that rotation of the driven member rotates the hinged gripping jaws, the mechanism operable in a first condition to couple the fastener to the driven member to transfer the implantation force from the driven member to the fastener, the mechanism being operable in a second condition to release the fastener from the driven member, the mechanism comprising a second actuator operable independent of the drive actuator to place the mechanism in the second condition.
