Abstract
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.
Claims19
An anastomotic connector comprising:
- an arterial connector having a distal arterial end co-axially implantable into an arterial passageway and a proximal arterial end, wherein an outer diameter of said distal arterial end is smaller than an outer diameter of said proximal arterial end;
- and
- a venous connector having a distal venous end co-axially implantable into a venous passageway and a proximal venous end, wherein an outer diameter of the distal venous end is larger than an outer diameter of the proximal venous end, said venous connector having a substantially conical body comprising a frame structure including a plurality of struts and a plurality of interstices located between said struts and a fluid impermeable material deposited on said struts such that said fluid impermeable material fills the interstices;
- wherein the inner diameter of the proximal arterial end is sized to receive the proximal venous end in an interference fit connection to form an anastomotic connector, the interference fit connection configured to be positioned at least partially outside the arterial passageway and the venous passageway, wherein the proximal venous end within the interference fit connection is bendable and configured to bend the anastomotic connector in an approximately U-shape when the arterial connector is deployed within the arterial passageway and the venous connector is deployed within the venous passageway;
- wherein said venous connector includes an anchoring device that extends radially outwardly at an acute angle from a longitudinal axis of a tubular main body of the venous connector at the distal venous end;
- and
- wherein said tubular main body of said venous connector is configured to stretch upon being exposed to arterial pressure while said anchoring device is configured to prevent expansion of the venous passageway.
