Abstract

Devices, systems, and methods for implanting radially expandable prostheses in the body lumens rely on tacking or anchoring the prostheses with separately introduced fasteners. The prostheses may be self-expanding or balloon expandable, and may include a single lumen or more than one lumen. After initial placement, a fastener applier system is introduced within the expanded prostheses to deploy a plurality of fasteners to at least one prosthesis end. The fasteners are usually helical fasteners which are releasably restrained on the fastener driver, and are delivered by rotation of the fastener driver. The fasteners may be applied singly, typically in circumferentially spaced-apart patterns about the interior of at least one end of the prosthesis. A lumen extension or lumens may be coupled to the prosthesis to extend the reach of the prosthesis within the implantation site. Fasteners may also be applied to the lumen extensions.

Claims

1. An apparatus for storing a fastener for securing a prosthesis comprising:

a base structure, and

at least one receptacle positioned within the base structure, the receptacle sized and configured to releasably store at least one helical fastener, wherein the receptacle is sized and configured to present the fastener to a fastener applier.

2. An apparatus according to claim 1 further including a pliable material within the receptacle to position a tip of the fastener in the pliable material to releasably restrain the fastener.

3. An apparatus according to claim 1 wherein the fastener is releasably restrained within the receptacle by friction between the fastener and the receptacle wall.

4. An apparatus for storing a fastener for securing a prosthesis comprising:

a base structure, and

at least one receptacle positioned within the base structure, the receptacle sized and configured to releasably store at least one helical fastener, wherein the helical fastener includes a fastener body having a distal end for penetrating tissue in response to a force and a proximal end for releasably coupling the fastener body to a fastener applier, and

a stop structure associated with the proximal end to prevent over-penetration of the fastener body into tissue, the stop structure bisecting the diameter of the fastener body.

5. An apparatus according to claim 4 wherein the stop structure is offset from the diameter of the fastener body.

6. An apparatus for storing a fastener for securing a prosthesis comprising:

a base structure,

at least one receptacle positioned within the base structure, the receptacle sized and configured to releasably store at least one fastener; and

a post positioned within the receptacle to releasably restrain the fastener, wherein the receptacle is sized and configured to present the fastener to a fastener applier.
