Publication number: 20230165698Abstract: A handle assembly for a prosthesis delivery device is disclosed. The handle assembly comprises a stationary main handle having a proximal end and a distal end and an outer surface extending therebetween. A first helical groove is formed in at least a portion of the outer surface of the main handle and a first trigger wire actuation mechanism disposed about the main handle and rotatably moveable relative to the main handle. A first trigger wire is operatively connected to the first trigger wire actuation mechanism, the first trigger wire having a prosthesis capture condition and a prosthesis release condition. Movement of the first trigger wire actuation mechanism causes movement of the first trigger wire thereby moving the first trigger wire from the prosthesis capture condition to the prosthesis release condition. Additional trigger wire actuation mechanisms operatively connected to one or more additional trigger wires may also be disposed about the main handle.Type: ApplicationFiled: December 1, 2022Publication date: June 1, 2023Applicant: Cook Medical Technologies LLCInventors: Ryan C.

Patent number: 11446168Abstract: Prostheses and methods of making the same are provided. The prosthesis has an internal branch configuration. A trough or branch opening is at least partially defined by a trough wall extending into a main lumen from a sidewall of the prosthesis. The internal branch extends from the trough within the main lumen towards one of the outflow end of the graft body in a helical, retrograde arrangement. Other arrangements are described. The prosthesis may include a scalloped fenestration having a width larger than the trough. The trough may be positioned along a tapered region of the prosthesis. The trough and internal branch may be made from the same graft material. The trough and internal branch, in addition to the main graft body, may be made from the same graft material.Type: GrantFiled: April 23, 2018Date of Patent: September 20, 2022Assignee: Cook Medical Technologies LLCInventors: Blayne A Roeder, Jarin A Kratzberg, Charles L Baxter, Chantelle King, Stephan Haulon
