Abstract:
1. An apparatus, comprising: a medical device and a marker wire coupled to said medical device, the medical device having a length and 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, 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; a first directional indicator coupled to said medical device and intersecting said marker wire, the first directional indicator comprising a first portion of a symbol; a second directional indicator coupled to said medical device and intersecting said marker wire, said second directional indicator offset from said first directional indicator, the second directional indicator 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.
