Abstract
An optical coupler guides one or more rotating second beams from an eccentric port to a fixed point on a detector. The coupler includes a housing having a distal face with an eccentric port. A central relay located inside the housing guides the rotating second beams to the fixed point on the detector.
Claims23
An optical coupler comprising:
- a housing with a distal face having an eccentric port and
- a central relay for guiding a rotating second beam from the eccentric port to a fixed point on a detector.
A system for identifying vulnerable plaque, the system comprising:
- a rotating catheter having a collection fiber and a delivery fiber extending therethrough;
- a stationary housing, the housing having a distal face being engaged with the rotating catheter;
- a first optical relay in optical communication with a central port on the distal face, the central port being in optical communication with the delivery fiber;
- a second optical relay in optical communication with an eccentric port on the distal face, the eccentric port being in optical communication with the collection fiber;
- and
- a central optical relay in optical communication with the second optical relay and a fixed point on a detector.
