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. ## Claims ### Claim 1 A prosthesis for directing flow through a passageway formed between a first bodily lumen and a second bodily lumen, the prosthesis comprising: a body having a proximal portion, a distal portion and a lumen extending therethrough; and a sleeve operably connected to the body at a connected portion, the sleeve having a proximal portion, a distal portion, and a sleeve lumen extending therethrough, at least a portion of the body positioned within at least a portion of the sleeve lumen and the distal portion of the sleeve being 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, wherein the sleeve is configured to allow fluid flow through the sleeve lumen from the first bodily lumen to the second bodily lumen. ### Claim 2 (depends on 1) The prosthesis of claim 1, wherein the body comprises a self-expanding stent. ### Claim 3 (depends on 1) The prosthesis of claim 1, wherein the body comprises a non-expandable stent. ### Claim 4 (depends on 1) The prosthesis of claim 1, wherein the body comprises a retention device at the proximal portion or the distal portion of the body or both the proximal portion and the distal portion of the body. ### Claim 5 (depends on 4) The prosthesis of claim 4, wherein the retention device comprises an expanded diameter at a distal end portion of the body or a proximal end portion of the body or both. ### Claim 6 (depends on 4) The prosthesis of claim 4, wherein the retention device comprises a pigtail configuration. ### Claim 7 (depends on 1) The prosthesis of claim 1, wherein the sleeve comprises polytetrafluoroethylene (PTFE). ### Claim 8 (depends on 1) The prosthesis of claim 1, wherein the sleeve comprises a fluid impermeable, flexible material so that the distal portion of the sleeve can conform to the wall of the first bodily lumen. ### Claim 9 (depends on 1) The prosthesis of claim 1, wherein a diameter of the sleeve distal portion is greater than a diameter of a mid portion of the sleeve. ### Claim 10 (depends on 1) The prosthesis of claim 1, wherein a diameter of the proximal portion of the sleeve is greater than a diameter of a mid portion of the sleeve. ### Claim 11 (depends on 1) The prosthesis of claim 1, wherein a diameter of a mid portion of the sleeve is greater than a diameter of a mid portion of the body and the mid portion of the sleeve and a mid portion of the body coaxially extend between the first body lumen and the second bodily lumen. ### Claim 12 (depends on 1) The prosthesis of claim 1, wherein the proximal portion of the sleeve is connected to the proximal portion of the body. ### Claim 13 (depends on 1) The prosthesis of claim 1, wherein the sleeve extends proximal to the proximal portion of the body. ### Claim 14 (depends on 1) The prosthesis of claim 1, further comprising a valve configured to restrict flow from the second bodily lumen toward the first bodily lumen. ### Claim 15 (depends on 1) The prosthesis of claim 1, wherein the body comprises at least one involuted portion configured to facilitate flow through the lumen of the sleeve. ### Claim 16 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 first bodily lumen and a second bodily lumen; positioning a distal portion of a sleeve and a distal portion of a body of the prosthesis within the first bodily lumen; positioning a proximal portion of a sleeve and a proximal portion of a 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; 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; and fluidly connecting the first bodily lumen to the second bodily lumen through a lumen of the sleeve. ### Claim 17 (depends on 16) The method of claim 16, further comprising delivering the prosthesis through the second bodily lumen to the first bodily lumen. ### Claim 18 (depends on 16) The method of claim 16, comprising delivering the prosthesis using an endoscopic ultrasound device. ### Claim 19 (depends on 16) The method of claim 16, comprising delivering the prosthesis to the first bodily lumen with the sleeve positioned against to the body. ### Claim 20 (depends on 16) The method of claim 16, comprising expanding the body comprising a self-expanding stent so that the expanded body has a diameter at a mid portion that is less than a diameter of the sleeve at a mid portion of the sleeve.
