Patent number: 9675237Abstract: To perform pelvic surgery, a directionally illuminating balloon catheter enters a bladder. The catheter has a multi-lumen shaft. The balloon defines an interior fluidically connected to a balloon inflation lumen and is inflated therethrough. The balloon comprises a light source, a light-radiating surface adjacent the shaft-balloon junction, and a substantially opaque surface disposed at a portion of the balloon other than the light-radiating surface such that the integrated light source illuminates a distal half of the environment outside the balloon. The balloon is inflated while in the bladder. Light from the light source is directed out through the light-radiating surface to illuminate at least a portion of a procedure area opposite the bladder-prostate junction. With the light illuminating the portion of the procedure area, at least a portion of a pelvic surgery is performed at the portion of the procedure area.Type: GrantFiled: June 18, 2015Date of Patent: June 13, 2017Assignee: Mayser, LLCInventors: Gary Kalser, Gregory L.
