Endoscopic anatomical feature tracking

A method of localizing a target anatomy involves advancing a ureteroscope to a target calyx of a kidney of a patient through at least a portion of a urinary tract of the patient, determining a positional offset between one or more position sensors associated with the ureteroscope and a target papilla of the kidney that is at least partially exposed within the target calyx, and determining a percutaneous access target based at least in part on one or more of a present position of the one or more position sensors or the positional offset.

Methods for surfactant enhanced laser-induced vapor bubbles for use in laser lithotripsy

Methods for surfactant enhanced laser-induced vapor bubbles for use in laser lithotripsy. Urinary tract stone disease is a common and costly disease that effects approximately 10% of the United States population. A preferred minimally invasive method for treatment of urinary tract stones is laser lithotripsy, which involves insertion of a flexible ureteroscope through the urinary tract to the stone's location, and then transmission of infrared (IR) laser energy through a flexible optical fiber, which is in turn placed through the single working channel of the ureteroscope. The IR laser energy is used for ablation of the urinary tract stone which is then removed. In order to have a more efficient ablation, the ureteroscope is fed with a surfactant composition which is flowed into the ureter and / or kidney of the subject. The laser causes larger bubbles to form in the surfactant composition, making a robust and longer lasting bubble.
