Claim Text:
1. An endovascular prosthesis delivery device comprising: a tubular member having a distal portion and a proximal portion, the distal portion having a porous surface defined by a plurality of circumferential rings, adjacent pairs of circumferential rings being interconnected by at least one longitudinal strut, the at least one longitudinal strut having a length in a longitudinal direction of the tubular member and a width in a circumferential direction of the tubular member, the porous surface comprising a decreasing gradient of longitudinal strut circumferential width between longitudinal struts connected to opposed sides of a single circumferential ring in a direction from the proximal portion to the distal portion, the distal portion comprising (i) two longitudinal struts coupled to a distal-most circumferential ring, and (ii) at least one aperture coupled to a distal end of at least one of the distal portion longitudinal struts and configured to couple with a proximal end of an endovascular prosthesis, and a pull wire disposed substantially parallel to a longitudinal axis of the tubular portion and configured to be disengaged from the at least one distal portion aperture when pulled in a direction substantially toward a distal end of the prosthesis.
