1. An apparatus comprising:
- a medical device and a marker wire coupled to said medical device, the medical device having a longitudinal axis, the marker wire extending such that a first portion of the marker wire extends in a circumferential direction about the longitudinal axis of the medical device and a second portion of the marker wire extends in a direction parallel to the longitudinal axis of the medical device, wherein the rotational orientation of the marker wire may be determined using an imaging device when the medical device is positioned within a bodily lumen.

Abstract
A medical device includes a rotational marker. A marker may be viewable under an imaging device, such as a fluoroscope or an MRI system. A rotational marker allows the rotational orientation of a medical device to be determined with respect to the surrounding environment. A medical device including a rotational marker may comprise an implantable medical device, a delivery system for delivery of an implantable medical device, and the like.

36. An apparatus comprising:
-
a medical device having a length and a longitudinal axis; and
a marker wire coupled to said medical device;
the marker wire having a first end and a second end, the first end and the second end being offset from one another along the length of the device, the first end and the second end being offset from one another in a circumferential direction about the longitudinal axis of the device, wherein the rotational orientation of the marker wire may be determined using an imaging device when the medical device is positioned within a bodily lumen.

37. A method of positioning an implantable medical device within a bodily lumen comprising:
-
a) providing a medical device having a rotational marker;
b) inserting the medical device into a bodily lumen and maneuvering the device to a worksite;
c) viewing the worksite and the device through an imaging device, the rotational marker being visible upon the imaging device;
d) positioning the medical device to a proper rotational orientation using the rotational marker as viewed upon the imaging system.
