Publication number: 20210068836Abstract: An end-to-end anastomotic connector is provided. The anastomotic connector includes solely an arterial connector and a venous connector. The inner diameter of the proximal end of the arterial connector is sized to directly receive the proximal end of the venous connector in an interference fit without the need for a graft material therebetween. The arterial connector and the venous connector are implanted in an artery and vein, respectively, to form a co-axial relationship with the respective vessel.Type: ApplicationFiled: February 7, 2019Publication date: March 11, 2021Inventor: Alexander S. YEVZLIN

Publication number: 20210069403Abstract: A one piece anastomotic connector is provided. The one piece anastomotic connector is substantially T-shaped in cross-section and has an arterial portion and a venous portion, the arterial portion is implantable into an arterial passageway and the venous portion implantable into a venous passageway. The venous portion and the arterial portion are integrally formed. The arterial portion allows for undisturbed, full flow of blood into extremities of a patient downstream the anastomotic connector.Type: ApplicationFiled: February 8, 2019Publication date: March 11, 2021Inventor: Alexander S.
