1. A vascular prosthesis, comprising:
a body, comprising a proximal portion, a tapered portion, a distal portion, and one or more bores;
wherein the tapered portion is between the proximal portion and the distal portion, extends around a circumference of the body, and a diameter of the proximal portion is larger than a diameter of the distal portion; and
a duct extending along at least a portion of a length of a wall of each of the one or more bores, the duct comprising:
a proximal end, a distal end, a lumen extending between the proximal end and the distal end, and a distal opening disposed adjacent the distal end,
wherein the distal opening is disposed within a wall of the tapered portion of the body, wherein the distal opening is in fluid communication with the lumen,
wherein the proximal end is configured to be selectively openable from a closed configuration to an opened configuration, and wherein the lumen has a length between 5 mm and 50 mm.
