Methods and systems for generating a visualization of a surface of an internal body cavity, such as an internal organ like the bladder, are provided. The approach generally includes inserting an endoscope into an internal body cavity, acquiring a video of the tissue surfaces defining the internal body cavity, stitching video frames together to generate a panoramic map of the tissue surfaces defining the internal body cavity, and displaying the panoramic map.

The present invention discloses a flexible digital ureteroscope that is at least partially disposable. The ureteroscope comprises a single-use catheter and a handle. The catheter comprises a distal end, a bend portion, and a proximal portion. The distal end has a rigid or semi-rigid shell that houses a set of micro lenses, an image sensor microchip, and a plurality of LED light sources. A working channel extends along the entire catheter and is coupled to a working channel port on the handle to receive various medical devices and irrigation lines during an endoscopic procedure. In addition, the catheter includes one or more steering wires to control the distal end to bend towards a desired direction. The rigid or semi-rigid shell of the distal end is made of a mix of polymer composite material with graphene nano-filler for enhancing thermal dissipation. The handle may be a single-use handle or a reusable handle. In case the handle is a reusable handle, it includes a battery module and a wireless communication module for communicating with a host machine wirelessly. In case the handle is a single-use handle, to reduce cost, the handle does not include a battery module and/or a wireless communication module. Rather, the single-use handle includes a host interface for receiving power from the host machine and transmits image data to the host machine.

A method involves positioning a housing in an ureteral access sheath that is positioned in a lumen in a living body, moving the housing toward calculus located in the ureteral access sheath, positioning the housing in the ureteral access sheath adjacent the calculus in the ureteral access sheath, drawing the calculus in the ureteral access sheath through the inlet and into the housing by suction in the interior of the housing, and removing the housing from the ureteral access sheath while the calculus remains in the housing.

A device for removing a urinary tract stone from a ureter may include an outer shaft, an inner shaft extending coaxially within the outer shaft, a self-expanding wire basket attached to a basket shaft extending coaxially within the inner shaft, an inflatable balloon and a handle. The balloon main include a rounded distal tip. The handle may include an inversion slider coupled to the inner shaft and configured to actuate the inner shaft, thereby inverting the distal tip of the inflatable balloon to form a pocket adapted to receive a urinary tract stone. The handle may also include a basket slider coupled to the basket shaft and configured to actuate the basket shaft to move the wire basket in and out of the inner shaft.
