US Patent 11684242 Imaging system

An imaging system for use in a patient is provided. The system includes an imaging probe, a rotation assembly, and a retraction assembly. The imaging probe collects image data from a patient site and includes an elongate shaft with a proximal end and a distal portion, with a lumen extending therebetween. A rotatable optical core is positioned within the elongate shaft lumen and an optical assembly is positioned in the elongate shaft distal portion. The optical assembly directs light to tissue at the patient site and collects reflected light from the tissue. The rotation assembly connects to the imaging probe and rotates the optical assembly. The retraction assembly connects to the imaging probe and retracts the optical assembly and the elongate shaft in unison.
