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.
Claims13
A catheter for optical coherence tomography (OCT), comprising:
- an elongate catheter body extending distally to proximally;
- an optical fiber in the elongate catheter body;
- and
- a lens assembly comprising a lens body having a concave proximal surface that is opposite from and at an angle relative to the distal end of the optical fiber, the lens body attached to and optically coupled with a distal end of the optical fiber by an interface medium;
- wherein the proximal surface has a compound radius having a first radius along a first axis that is different from a second radius along a second axis;
- wherein the proximal surface comprises a reflective material configured so that at least 90% of a light reaching the lens body from the distal end of the optical fiber reflects off of the proximal surface;
- and
- 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 between the distal end of the optical fiber and the interface medium.
