Abstract:
1. A medical device delivery system for deploying an intraluminal medical device with a body vessel, comprising: a dilator having a lengthwise axis and including a main body, a head member, and a rotatable connection disposed between and connecting the main body and the head member, the main body, the head member and the rotatable connection positioned on the lengthwise axis of the dilator, the main body having a first proximal end and a first distal end and the head member having a second proximal end and a second distal end, the rotatable connection connecting the first distal end and the second proximal end and enabling the head member to rotate about the lengthwise axis of the dilator independent of rotation of the main body, the second proximal end defining a mounting region and the second distal end including first and second orienting members, each of the first and second orienting members comprising a resilient member having an orienting member proximal end and an orienting member distal end attached to the second distal end and a middle portion substantially free of the second distal end, the orienting member distal end circumferentially offset from the orienting member proximal end; an intraluminal medical device disposed on the mounting region; and an elongate tubular member circumferentially disposed about the main body and at least the mounting region of the head member and the intraluminal medical device; wherein the first and second orienting members are opposibly positioned with respect to the lengthwise axis and extending outwardly from the head member to define a major transverse axis relative to the lengthwise axis such that the orienting members are adapted to expand against and contact a wall of said body vessel and to cause the head member and intraluminal medical device to rotate within said body vessel as said delivery system is advanced within said body vessel.
