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.

A tool for applying an implantation force to a fastener sized and configured for implantation in tissue in response to an implantation force applied according to prescribed conditions, the tool comprising:
- a tool body;
- a driven member carried by the tool body and being operable to apply the implantation force;
- a mechanism on the driven member to couple the fastener to the driven member to transfer the implantation force from the driven member to the fastener;
- and
- a controller coupled to the driven member, the controller including:
- an initial phase operating the driven member to apply the implantation force under conditions than are short of the prescribed conditions;
- a lull phase commencing at the end of the initial phase interrupting operation of the driven member;
- a final phase operating the driven member under conditions that supplement the conditions of the initial phase to achieve the prescribed conditions,
- the controller requiring, after the initial phase, a prescribed command to advance from the lull phase to the final phase.
An assembly for applying an implantation force to a fastener sized and configured for implantation in tissue in response to an 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 on the driven member 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.
