Publication number: 20230404586Abstract: A medical device for an anastomosis is provided. The medical device distinguishes an inner tubular layer, an outer tubular layer, and a support element defining a longitudinal axis. It further distinguishes two or more independent C-rings distributed and positioned at an acute orientation angle relative to the longitudinal axis of the support element at one end of the support element. The support element and the two or more C-rings are embedded in between the inner and the outer tubular layers. The types of applications one could envision are e.g. a proximal anastomosis, distal anastomosis, or side-to-side anastomoses, in a customized pre-fabricated graft. Embodiments of the invention could also be incorporated into an anastomotic connector device design. Embodiments of the invention could further be envisioned as vascular grafts applications such as Coronary Artery Bypass Graft (CABG), dialysis access grafts and peripheral vascular applications.Type: ApplicationFiled: September 1, 2023Publication date: December 21, 2023Inventors: Yonatan Gray, Mohammed El-Kurdi

Publication number: 20210196445Abstract: Provided herein our graft devices for a patient comprising one or more layers, such as an inner layer and an outer layer. The inner layer comprises a first porous arrangement of fibers defining a first tube comprising an inner wall and an outer wall. The outer layer comprises a second porous arrangement of fibers defining a second tube comprising an inner wall and an outer wall. The second tube surrounds the first tube. A plurality of macropores extend through at least the inner and outer wall of the first tube. The inner and/or the outer layer can comprise a biofragmentable material configured to mechanically fracture into one or more fragments over time. Methods of creating graft devices are also disclosed.Type: ApplicationFiled: June 7, 2019Publication date: July 1, 2021Inventors: Mohammed El-Kurdi, Ayotte Ryan, Anh Thi Dinh, Kevin Farrell, Jon McGrath

Patent number: 9622849Abstract: A tubular tissue graft device is provided comprising a tubular member and a restrictive fiber matrix of a bioerodible polymer about a circumference of the tubular tissue. The matrix may be electrospun onto the tubular tissue. In one embodiment, the tubular tissue is from a vein, such as a saphenous vein, useful as an arterial graft, for example and without limitation, in a coronary artery bypass procedure. 5 Also provided is method of preparing a tubular graft comprising depositing a fiber matrix of a bioerodible polymer about a perimeter of a tubular tissue to produce a tubular tissue graft device. A cardiac bypass method comprising bypassing a coronary artery with a tubular tissue graft device comprising a vein and a restrictive fiber matrix of a bioerodible polymer about a circumference of the vein also is provided.Type: GrantFiled: October 28, 2010Date of Patent: April 18, 2017Assignee: University of Pittsburgh—Of the Commonwealth System of Higher EducationInventors: Mohammed El-Kurdi, J.
