1. An assembly for open surgical repair of a damaged portion of a body vessel, the assembly comprising:
a prosthesis having a first end and a second end, the prosthesis being expandable from a constricted condition wherein at least the first and second ends have a diameter less than a diameter of the body vessel at said damaged portion, to an expanded condition wherein the prosthesis ends engage an interior surface of said body vessel;
a first splittable sheath for maintaining the prosthesis first end in said constricted condition, the first splittable sheath comprising a generally cylindrical body having a first end portion, a second end portion, a passageway extending therethrough, and an elongated tab member integral with the first splittable sheath, the tab member being engaged at said second end portion, said tab member positionable along said generally cylindrical body for initiating a splitting of said generally cylindrical body of said first splittable sheath from said first end portion toward said second end portion, wherein said first splittable sheath is disposed upon the first end of the prosthesis and wherein said splitting of said first splittable sheath extends from said first end of said prosthesis toward said second end of said prosthesis, and wherein the elongated tab member of the first splittable sheath is positioned along said generally cylindrical body such that when said generally cylindrical body is split, the elongated tab member comprises a twist; and
a second splittable sheath for maintaining the prosthesis second end in said constricted condition, the second splittable sheath comprising a generally cylindrical body having a first end portion, a second end portion, a passageway extending therethrough, and an elongated tab member integral with the second splittable sheath, the tab member being engaged at said second end portion, said tab member positionable along said generally cylindrical body for initiating a splitting of said generally cylindrical body of said second splittable sheath from said first end portion toward said second end portion, wherein said second splittable sheath is disposed upon the second end of the prosthesis and wherein said splitting of said second splittable sheath extends from said second end of said prosthesis toward said first end of said prosthesis, wherein at least one of said sheaths has a length of about 10-12 mm.
