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. A fastener applier for securing a prosthesis comprising

a handle assembly positioned at the caudal end of the fastener applier,

a fastener applier shaft coupled to the handle assembly, the fastener applier shaft comprising a cephalad end

a fastener driver for advancing a fastener into the prosthesis and tissue,

the fastener driver coupled to the fastener applier shaft at the cephalad end of the fastener applier shaft, the fastener driver including a housing and a release latch, wherein the release latch prevents premature release of the fastener from the fastener driver, and the fastener is a helical fastener.

2. A fastener applier according to claim 1 wherein the fastener driver housing includes an internally threaded portion and a non-threaded portion, the non-threaded portion providing an area where the fastener can be rotated but not advanced out of the driver, the advancement out of the driver only taking place if the fastener has been previously engaged in tissue or the prosthesis.

3. A fastener applier according to claim 1 wherein the handle assembly further includes a motion control assembly to be used by an operator, the motion control assembly providing motion control of the fastener within the fastener driver.

4. A fastener applier according to claim 3 wherein the motion control assembly includes a forward control function and a reverse control function.

5. A fastener applier according to claim 1 wherein the handle assembly further includes an indication assembly to provide information to an operator, the indication assembly providing at least one of an audible and visual indication.

6. A fastener applier according to claim 5 wherein the information includes at least one of a fastener position or timing or status or error, or any combination.

7. A fastener applier according to claim 1 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 the 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.

8. A fastener applier according to claim 7 wherein the stop structure is offset from the diameter of the fastener body.
