Abstract
A catheter including a monitoring body and a pair of markers disposed on the monitoring body, each marker of the pair of markers encircling the monitoring body, wherein the pair of markers are configured to indicate, through their appearance from a given point of view, an orientation of the monitoring body.
Claims16
A catheter comprising:
- a monitoring body having an axis extending along a length of the monitoring body;
- an imaging sensor disposed at a distal end of the monitoring body;
- and
- a pair of elliptical hoops fixed on the monitoring body and offset from one another, each of the elliptical hoops encircling the monitoring body, wherein a first elliptical hoop of the pair is disposed in a first plane having an angle about 45 degrees to the axis and a second elliptical hoop of the pair is disposed in a second plane having an angle about 45 degrees to the axis and rotated 90 degrees, on the axis, from the first plane such that the pair of elliptical hoops indicate, through their combined appearance with the distal end from a given point of view, an orientation and exact rotational position of the imaging sensor over 360 degrees of rotation of the monitoring body about the axis.

A catheter comprising:
- an outer sheath;
- an inner sheath disposed within the outer sheath;
- a guidewire;
- a monitoring body having an axis disposed along a length of the monitoring body and disposed within the inner sheath;
- an imaging sensor disposed at a distal end of the monitoring body;
- and
- a pair of radio-opaque elliptical hoops fixed on the monitoring body and offset from one another, each radio-opaque elliptical hoop of the pair of radio-opaque elliptical hoops encircling the monitoring body, wherein a first elliptical hoop of the pair is disposed in a first plane having an angle about 45 degrees to the axis and a second elliptical hoop of the pair is disposed in a second plane having an angle about 45 degrees to the axis and rotated 90 degrees, on the axis, from the first plane such that the pair of radio-opaque elliptical hoops indicate, through their combined appearance with the distal end in a two-dimensional projection, an orientation of the imaging sensor over 360 degrees of rotation of the monitoring body about the axis.
