Abstract
A catheter system for optical coherence tomography includes an elongate catheter body, an optical fiber in the elongate catheter body, and an anamorphic lens assembly coupled with a distal end of the optical fiber. The optical fiber and the lens assembly are together configured to provide a common path for optical radiation reflected from a target and from a reference interface between the distal end of the optical fiber and the lens assembly.
Claims15
A catheter for optical coherence tomography (OCT), comprising:
- an elongate catheter body;
- an optical fiber in the elongate catheter body;
- and
- a lens assembly, the lens assembly comprising:
- an elongate body having a channel extending therethrough, a distal end of the optical fiber positioned within the channel;
- a lens body integral with the elongate body;
- and
- an interface medium within the channel and attaching the lens body to the optical fiber;
- wherein the optical fiber and the lens assembly are together configured to provide a common path for optical radiation reflected from a target and from a reference interface formed by the interface medium.
