1. An implantable valve device comprising:
- a tubular mesh scaffolding comprising a plurality of filaments, the mesh scaffolding defining a lumen extending therethrough to a distal scaffolding end;
only one filament of the plurality of filaments extending distally a distance away from the distal scaffolding end and forming only a single loop, the single loop comprising only a single cross-over of the one filament;
a covering extending continuously along the mesh scaffolding, the single loop, and a valve section; and
the valve section extending distally beyond the distal scaffolding end, the valve section comprising;
a valve connected to, and extending longitudinally from, the mesh scaffolding, wherein the valve is an extension of the covering and comprises the single loop, the valve closing off the lumen of the mesh scaffolding;
wherein the valve section includes only the one filament of the plurality of filaments.

Abstract
An anti-reflux valve having a mesh scaffolding and a valve extending from the mesh scaffolding, the valve supported by a loop. The loop can be formed by a filament extending from the mesh scaffolding or by a loop filament separate from the filament(s) forming the mesh scaffolding.

7. An implantable valve device comprising:
-
a mesh scaffolding section comprising; a filament forming a tubular mesh scaffolding defining a lumen extending therethrough to a distal scaffolding end, the distal scaffolding end being an end of the mesh scaffolding section; a covering extending continuously over the mesh scaffolding and a valve section; the valve section extending distally beyond the distal scaffolding end of the mesh scaffolding section, the valve section consisting of; a valve closing off the lumen of the mesh scaffolding, wherein the valve is an extension of the covering; and only a single loop, wherein the single loop is formed by the filament extending distally for a distance from the distal scaffolding end along the valve so that the single loop has a longitudinal length, wherein the single loop comprises only a single cross-over of the filament. - View Dependent Claims (8, 9, 10, 11, 12)

13. An implantable valve device comprising:
-
a mesh scaffolding section comprising; a tubular mesh scaffolding including a filament, the tubular mesh scaffolding defining a lumen extending therethrough from a proximal end of the tubular mesh scaffolding to a distal end of the tubular mesh scaffolding; a valve section extending distally beyond the mesh scaffolding section, the valve section consisting of; only a single loop of the filament extending distally beyond the distal end of the mesh scaffolding, wherein the single loop comprises only a single cross-over of the filament; and a covering extending continuously along the mesh scaffolding and the valve section, wherein the covering defines a valve having an opening sized and configured for food to pass therethrough, the valve extending longitudinally and distally from the distal end of the mesh scaffolding, wherein the single loop has a spring radial force allowing the valve to move between an open state, allowing food to pass therethrough during peristalsis, to a collapsed state, thereby closing the scaffolding lumen. - View Dependent Claims (14, 15, 16, 17)
