Rotational markers

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 comprising four contiguous portions defining the perimeter of a closed area, wherein two portions extend in a circumferential direction about the longitudinal axis of the medical device but not entirely about the circumference of the medical device, and two portions linearly extend 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;
• a first directional indicator coupled to said medical device and oriented in a direction non-parallel to the longitudinal axis, the first directional indicator intersecting said marker wire and comprising a first portion of a symbol;
• a second directional indicator coupled to said medical device offset from said first directional indicator and oriented in a direction non-parallel to the longitudinal axis, the second directional indicator intersecting said marker wire and comprising a second portion of the symbol;
• wherein images of said first and second directional indicators physically connect to form the symbol when viewed from a proper rotational orientation about the longitudinal axis when viewed orthogonally to the longitudinal axis using an imaging device.

A method of positioning an implantable medical device within a bodily lumen, comprising:

• a) providing a medical device having a longitudinal axis and a rotational marker coupled to the medical device, the rotational marker comprising:
• a marker wire comprising four contiguous portions defining the perimeter of a closed area, wherein two portions extend in a circumferential direction about the longitudinal axis of the medical device but not entirely about the circumference of the medical device, and two portions linearly extend in a direction parallel to the longitudinal axis of the medical device the closed area having a length that is less than the length 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, and
• a first directional indicator coupled to said medical device, the first directional indicator intersecting said marker wire and comprising a first portion of a symbol,
• a second directional indicator coupled to said medical device offset from said first directional indicator, the second directional indicator intersecting said marker wire and comprising a second portion of the symbol, wherein images of said first and second directional indicators physically connect to form the symbol when viewed from a proper rotational orientation using an imaging device;
• 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 and the first and second directional indicators being visible upon the imaging device, wherein the rotational orientation of the marker wire may be determined using the imaging device;
• d) positioning the medical device to a proper rotational orientation using the rotational marker and the first and second directional indicators as viewed orthogonally to the longitudinal axis upon the imaging system.
