Abstract
A prosthesis and a method for directing flow through a passageway formed between a first bodily lumen and a second bodily lumen are provided. The prosthesis includes a body having a proximal portion, a distal portion and a lumen extending therethrough. The prosthesis also includes a sleeve operably connected to the body at a connected portion. The sleeve has a proximal portion, a distal portion, and a sleeve lumen extending therethrough. At least a portion of the body is positioned within at least a portion of the sleeve lumen and the distal portion of the sleeve is free from connection to the distal portion of the body and extendable away from the body to contact a wall of the first bodily lumen. The sleeve is configured to allow fluid flow through the sleeve lumen from the first bodily lumen to the second bodily lumen.
Claims18
A method of directing flow through a passageway formed between a first bodily lumen and a second bodily lumen, the method comprising:
- delivering a prosthesis comprising a body and a sleeve to a first bodily lumen and a second bodily lumen;
- positioning a distal portion of the sleeve and a distal portion of the body of the prosthesis within the first bodily lumen;
- positioning a proximal portion of the sleeve and a proximal portion of the body of the prosthesis within the second bodily lumen so that a portion of the body and a portion of the sleeve extend across the peritoneum between the first bodily lumen and the second bodily lumen, the sleeve being connected to the body at a connected portion;
- allowing the distal portion of the sleeve to extend away from the distal portion of the body and to conform to a wall of the first bodily lumen when the distal portion of the sleeve is positioned in the first bodily lumen;
- wherein the first bodily lumen and the second bodily lumen are fluidly connectable through a lumen of the sleeve so that flow can occur through the lumen of the sleeve from the first bodily lumen to the second bodily lumen, and wherein the sleeve is configured to allow fluid flow through the sleeve lumen between an outer surface of the body and an inner surface of the sleeve from the first bodily lumen to the second bodily lumen.
A method of directing flow through a passageway formed between a first bodily lumen and a second bodily lumen, the method comprising:
- delivering a prosthesis to a treatment site, the prosthesis comprising a body and a sleeve surrounding at least a portion of the body, the treatment site comprising a first bodily lumen and a second bodily lumen;
- positioning a distal portion of the sleeve and a distal portion of the body of the prosthesis within the first bodily lumen;
- positioning a proximal portion of the sleeve and a proximal portion of the body of the prosthesis within the second bodily lumen so that a portion of the body and a portion of the sleeve extend across the peritoneum between the first bodily lumen and the second bodily lumen;
- the distal portion of the sleeve being extendable away from the distal portion of the body and conformable to a wall of the first bodily lumen when the distal portion of the sleeve is positioned in the first bodily lumen, and wherein fluid is flowable between an outer surface of the body and an inner surface of the sleeve from the first bodily lumen to the second bodily lumen.
