Patent attributes
Devices, systems, and methods use a catheter device sized and configured for introduction to a targeted site in a hollow body organ or blood vessel. The catheter device includes a first release mechanisms coupled to the prosthesis to secure at least one region of the prosthesis to the catheter shaft, and a second release mechanism coupled to the prosthesis in cooperation with the first release mechanism to prevent full release of the at least one region of the at least one region of the prosthesis from the catheter shaft after actuation of the first release mechanism. A fastening device sized and configured for introduction to the targeted site in the hollow body organ or blood vessel occupied by the catheter device, includes an actuator to deploy a fastener in the at least one region of the prosthesis after actuation of the first release mechanism and before actuation of the second release mechanism.
