MEDICAL DEVICE DELIVERY SYSTEMS THAT FACILITATE MEDICAL DEVICE PLACEMENT IN THE PRESENCE OF ULTRASONIC WAVES
First Claim
1. A medical device delivery system that facilitates medical device placement in the presence of ultrasonic waves, said delivery device comprising:
- an elongate tubular member having a proximal end, a distal end, and defining a passageway extending between the proximal and distal ends, the elongate tubular member including first and second wall portions, the second wall portion adapted to reflect said ultrasonic waves differently than the first wall portion;
a dilator disposed within the passageway and defining a mounting region; and
an intraluminal medical device disposed on the mounting region and including a functional mechanism, at least a portion of the functional mechanism disposed substantially adjacent the second wall portion of the elongate tubular member.

Abstract
Delivery systems, methods of fabricating delivery systems, and methods of implanting intraluminal medical devices at a point of treatment within a body vessel are provided. Delivery systems include an elongate tubular member that has first and second wall portions with different acoustic impedences. An intraluminal medical device is disposed on a mounting region of a dilator and within the elongate tubular member. One of the wall portions of the elongate tubular member is positioned substantially adjacent a functional mechanism of the intraluminal medical device. This positioning facilitates placement of the intraluminal medical device within a body vessel in a particular orientation by observing the differential reflection of ultrasonic waves caused by the different acoustic impedences of the first and second wall portions of the elongate tubular member. Rotatation of the delivery system following and/or during such an observation can be employed to achieve a desired orientation of the intraluminal medical device within the body vessel.
