A recently granted patent (Publication Number: US11903677B2) discloses a method for crossing chronic total occlusions in patients. The method involves advancing an occlusion crossing catheter into the occluded body lumen and rotating a distal tip of the catheter, which includes a helical blade and an optical coherence tomography (OCT) imaging sensor. The OCT sensor captures images of the body lumen, aided by markers that obstruct imaging periodically. Based on the OCT images and markers, the catheter is steered within the patient's body lumen.

Furthermore, the method includes features such as a fixed jog near the rotatable tip, a bend proximal to the tip for steering, and the use of selective stiffening and tendon members for catheter manipulation. The catheter also allows for flushing of the imaging sensor region with minimal fluid, alignment of image data with fluoroscopy images, and display of the imaged region on a screen. Additionally, the method involves advancing a guidewire past the occlusion and separating tissue in the lumen by rotating the rotatable tip while advancing the catheter. These innovative features aim to improve the efficiency and effectiveness of crossing chronic total occlusions, ultimately benefiting patients undergoing such procedures.
