1. A prosthesis comprising:
- a stent with an outer surface, the stent comprising;
a proximal stent flange;
a proximal stent segment extending distally from the proximal stent flange;
an enlarged stent segment extending distally from the proximal stent segment;
a polymeric cover fully covering the outer surface of the stent, the polymeric cover forming an outer surface of the prosthesis; and
a connecting segment formed by a tubular section of the polymeric cover extending distally from the enlarged stent segment, the connecting segment consisting of the polymeric cover.

Abstract
A prosthesis that when implanted in the gastrointestinal tract does not impede the normal function of the pyloric sphincter. In some instances, the prosthesis is implanted as part of, or after, a sleeve gastrectomy procedure. The prosthesis includes a stent with an outer surface and a polymeric cover fully covering the outer surface of the stent. The stent includes a proximal stent flange; a proximal stent segment extending distally from the proximal stent flange; and an enlarged stent segment extending distally from the proximal stent segment.

15. A proximal bariatric prosthesis comprising a single stent layer forming an inner layer of the bariatric prosthesis and a polymeric cover forming an outer layer of the bariatric prosthesis,
the single stent layer comprising: -
a proximal stent flange, the proximal stent flange forming a proximal end of the bariatric prosthesis; a distal stent flange, the distal stent flange forming a distal end of the bariatric prosthesis; a proximal cylindrical stent segment extending distally from the proximal stent flange; an enlarged stent segment extending distally from the proximal cylindrical stent segment; and a connecting segment extending distally from the enlarged stent segment to the distal stent flange, the connecting segment consisting of the polymeric cover; wherein the polymeric cover is attached to an outer surface of the single stent layer. - View Dependent Claims (16, 17)

18. A bariatric prosthesis comprising a single stent layer and a polymeric cover,
the single stent layer comprising: -
a proximal stent, the proximal stent consisting of; a proximal stent flange having a variable diameter; a proximal cylindrical stent segment extending distally from the proximal stent flange, the proximal cylindrical stent segment having a uniform diameter; and an enlarged stent segment extending distally from the proximal cylindrical stent segment, the enlarged stent segment having a variable diameter; and a distal stent consisting of a distal stent flange having a variable diameter, a proximal end of the distal stent spaced apart from a distal end of the proximal stent to define a gap therebetween; wherein the polymeric cover is attached to an outer surface of the proximal stent;
is attached to an outer surface of the distal stent; and
interconnects the proximal and distal stents and spans the gap between the proximal end of the distal stent and the distal end of the proximal stent. - View Dependent Claims (19)
