AI Technical Summary
Technical Problem
Existing methods for end-to-side anastomosis fail to effectively prevent fluid leakage during the anastomosis procedure, particularly in vascular applications, where blood or fluid leakage is a significant concern.
Method used
A tissue connection stent with a diametrically expandable lattice structure, featuring a proximal tubular region and a distal flange, is delivered through a tubular graft and secured to the luminal surface of an anatomic passageway, providing a fluid seal and allowing controlled fluid flow after deployment.
Benefits of technology
The stent effectively prevents substantial fluid leakage during and after the anastomosis procedure, reducing procedure time and standardizing the method, while facilitating minimally invasive surgical techniques.

Abstract
A device, assembly and method for end-to-side connection to anatomical tissue is disclosed. The device includes a tissue connection stent having a proximal closure to create and maintain a substantial degree of hemostasis. The assembly and method include using a tubular graft member coupled to a plurality of distally projecting tines extending from a distal aspect of the graft that couples the graft to an abluminal wall surface of an anatomic passageway, and the tissue connection stent is then introduced through a central lumen of the graft member, into and through an opening created in the wall of the anatomic passageway, and the tissue connection stent is deployed within the opening and a distal flange of the stent is seated against a luminal wall of the anatomic passageway while the proximal closure is maintained in a closed position until it is deployed to allow fluid flow through the stent.
