Patent number: 10292708Abstract: A device for creating a fistula between blood vessels operates in conjunction with a guidewire to locate and position itself so that it straddles both vessels and is able to draw them together. A fixing agent is released either from within the device or from an external needle, or both, into the procedural site. The fixing agent functions to hold the relative position of the two vessels, to seal the surrounding tissue so that any leaks that do occur don't spread into the tissue to create a hematoma, and to limit expansion of the fistula. After the vessels are in close proximity to each other and the fixing agent is applied, the device of the invention employs a cutting mechanism which opens a portal between the two vessels.Type: GrantFiled: February 13, 2015Date of Patent: May 21, 2019Assignee: AVENU MEDICAL, INC.Inventors: Seth Arnold Foerster, Brad Mathew Kellerman, Mark Andrew Ritchart, Justin Kellogg Mann

Patent number: 9788947Abstract: An embodiment of the invention includes a sewing cuff for aortic heart valves that better approximates native anatomy by better mating with the crown-like anatomical annulus. Limiting distortion of the crown-like annulus provides better blood flow and overall valve function and provides a physician greater ease of implantation since native anatomy is not flattened. Thus, the surgeon may attach sutures to the fibrous tissue of the crown-like anatomical annulus without distorting the shape of the native anatomy. An embodiment includes a scalloped sewing cuff assembly (with semilunar arches) that tracks the crown-like annulus. Another embodiment provides a sewing cuff positioned over the majority of the valve's length, thus allowing the surgeon greater flexibility as to where he or she can attach sutures to the surgical annulus. Conventional valves, which are primarily “low-profile” devices, do not offer such ability. Other embodiments are described herein.Type: GrantFiled: April 18, 2016Date of Patent: October 17, 2017Assignee: On-X Life Technologies, Inc.Inventors: Francisco Javier Ruyra-Baliarda, Josep Gatell Ferre, Fletcher D.

A device for a vascular anastomosis includes tissue engaging portions that can move between at least two configurations. In some embodiments, the tissue engaging portions move without the aid of moving parts, while in other embodiments the tissue engaging portions extend from one or more movable wings. The tissue engaging portions may be separated by a first distance when in a pre-deployment configuration and by a second distance when in a deployed configuration. A method includes engaging a plurality of tissue engaging members of a coupling device against first end tissue. After selectively engaging the tissue engaging members and first end tissue, the first end tissue is stretched by at least moving the tissue engaging members. The stretched first end tissue is coupled to the second end tissue by mating the coupling device to a mating anastomosis device.Type: GrantFiled: April 15, 2011Date of Patent: May 9, 2017Assignee: The University of Utah Research FoundationInventors: Jayant P. Agarwal, Bruce K. Gale, Lam Nguyen, Cory Shorr, Brian Stauffer, Cody Lee Gehrke

Patent number: 9597082Abstract: A cuff is used to provide a form for curing fluid about the exterior of an end-to-end anastomosis site. The cuff includes a port through which fluid may be injected to reach an interior space defined between the exterior of tissue at the anastomosis site and the inner surface of the cuff. A circular stapler may be used as a mandrel for the cuff and fluid. Alternatively, inflatable balloons may be used as a mandrel. The curing fluid may comprise a mixture of fibrin and thrombin.Type: GrantFiled: March 14, 2013Date of Patent: March 21, 2017Assignee: Ethicon Endo-Surgery, LLCInventors: Michael J. Stokes, Edward G. Chekan, Charles J. Scheib, Andrew C. Yoo
