Drainage stent and associated method
First Claim
1. An implantable device for facilitating fluid flow between a branch of a bifurcated lumen and an interior region of the implantable device, the implantable device comprising:
- a scaffolding of struts formed from a tube of memory material and having a proximal end and a distal end;
a cover applied to and between the scaffolding of struts to define an interior region within the scaffolding; and
at least one drainage region having a proximal end, a distal end, and at least one drainage hole defined between the scaffolding and through the cover such that fluid is capable of flowing through the drainage hole, wherein the drainage region is offset from the proximal and distal ends of the scaffolding to facilitate fluid flow between the branch of the bifurcated lumen and the interior region of the scaffolding.

Abstract
A stent for facilitating flow between a branch of a bifurcated lumen and an interior region of the stent is provided. The stent includes proximal and distal ends and an interior region defined therethrough. The stent typically includes scaffolding having a cover applied thereto. The stent also includes at least one drainage region having at least one drainage hole defined between the scaffolding and through the cover such that fluid is capable of flowing through the drainage holes. The drainage region is typically offset from the proximal and/or distal end to facilitate fluid flow between the branch of the bifurcated lumen and the interior region of the stent.

15. A method for manufacturing an implantable device for facilitating fluid flow between a branch of a bifurcated lumen and an interior region of the implantable device, the method comprising:
-
forming a scaffolding from a tube of memory material having a proximal end and a distal end;
applying a cover to and between the scaffolding of struts to define an interior region within the scaffolding; and
defining at least one drainage region having at least one drainage hole between the scaffolding and through the cover such that fluid is capable of flowing through the drainage hole, wherein the drainage region is offset from the proximal and distal ends of the scaffolding to facilitate fluid flow between the branch of the bifurcated lumen and the interior region of the implantable device. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25)

26. An implantable device for facilitating fluid flow between a branch of a bifurcated lumen and an interior region of the implantable device, the implantable device comprising:
-
a scaffolding of struts formed from a tube of memory material and having a proximal end and a distal end;
a cover applied to and between the scaffolding of struts to define an interior region within the scaffolding; and
a plurality of drainage holes defined between the scaffolding and through the cover such that fluid is capable of flowing through each of the drainage holes, wherein each of the drainage holes is offset from the distal end of the scaffolding to define a gap therebetween and to facilitate fluid flow between the branch of the bifurcated lumen and the interior region of the scaffolding. - View Dependent Claims (27, 28, 29, 30, 31, 32)
