Abstract

An anastomotic connector comprises a generally tubular access port having a first end and a second end and a main body portion in fluid communication with the second end of the access port that is structured to be deployed within a fluid passageway. The main body portion includes an expandable mesh frame defining a pair of flanges extending outwardly from the second end of the access port and a retention strap extending across the second end of the access port. The pair of flanges and the retention strap are structured to exert a radial force on an internal surface of a fluid passageway when the mesh frame of the main body portion is expanded within the fluid passageway. Furthermore, the pair of flanges and the retention strap allow the passage of fluid to the distal tissues that the native fluid passageway is supplying.

Claims (9)

1. An anastomotic connector comprising: a generally tubular access port having a first end and a second end; and a main body portion in fluid communication with the second end of the access port and structured to be deployed within a fluid passageway, the main body portion including a self-expanding mesh frame defining a pair of self-expanding flanges extending radially outwardly from the second end of the access port to form a lateral axis, said pair of self-expanding flanges structured to alone exert a radial force solely against a first portion of an internal surface of the fluid passageway; and a self-expanding retention strap formed with said self-expanding flanges, said self-expanding retention strap having a longitudinal axis that is substantially perpendicular to the lateral axis of said flanges, said retention strap and said flanges having a substantially T-shaped structure in cross-section, as viewed along an axis substantially perpendicular to said longitudinal axis and said lateral axis, said retention strap extending across the second end of the access port and structured to exert a radial force solely on a second portion of the internal surface of the fluid passageway, said second portion of the internal surface opposing said first portion of the internal surface of the fluid passageway against which said pair of self-expanding flanges are structured to alone exert said radial force.

2. The anastomotic connector of claim 1 , wherein said main body portion include a side access port extending substantially perpendicular from the main body portion.

3. The anastomotic connector of claim 1 , wherein the mesh frame is formed from Nitinol.

4. The anastomotic connector of claim 1 , wherein the mesh frame of the main body portion includes a biocompatible covering.

5. The anastomotic connector of claim 4 , wherein the biocompatible covering is formed on an inner side of the mesh frame.

6. The anastomotic connector of claim 4 , wherein the biocompatible covering is formed on an outer side of the mesh frame.

7. The anastomotic connector of claim 4 , wherein the biocompatible covering comprises expanded Polytetrafluoroethylene (ePTFE).

8. The anastomotic connector of claim 1 , wherein the generally tubular access port includes self-expanding mesh frame.

9. The anastomotic connector of claim 4 , wherein the mesh frame of the access port includes an expanded Polytetrafluoroethylene (ePTFE) covering.
