Systems and methods for treating a patient may include accessing an anatomical structure with a single use visualization device, using the imaging capabilities of the single use visualization device within the anatomical structure, and in some cases, advancing the single use visualization device beyond the anatomical structure to and toward another anatomical structure within the patient. Disposable elements may be used with or added to the single use visualization device to accomplish tasks normally performed with reusable devices.

The subject matter described herein includes a kidney stone suction tube device and related methods of use. According to one example, the disclosed subject matter includes a suction tube device comprising a flexible tubing element comprising a modified suction tube portion characterized as having U-shaped hollow lumen channel and an intra-renal portion characterized as having circular shaped lumen channel. The intra-renal portion of the suction tube device further includes a collection cylinder section configured for storing kidney stone fragments. In addition, the connection of the modified suction tube portion and the collection cylinder section includes a mesh filter element configured to prevent admittance of kidney stones into the modified suction tube portion of the flexible tubing element.

A ureteroscope system includes a handle; an elongated shaft extends from the handle to a distal end and includes a working channel which is opened at the distal end; an external member extends from a proximal end to a distal end and is coupled to the shaft, the member includes a hub and a tube defining a first external channel; and a coupling mechanism defines first and second tubes and is coupled the distal end of the member to the distal end of the shaft. The first tube defines a first lumen and the second tube defines a second lumen which is sized and shaped to receive a distal end of the member. A proximal portion of the first tube is sized and shaped to be inserted into a distal portion of the shaft such that the first lumen is opened to the working channel.

Various embodiments disclosed relate to drug-coated balloon catheters for treating, preventing, or reducing the recurrence of a stricture and/or cancer, or for treating benign prostatic hyperplasia (BPH), in a non-vascular body lumen and methods of using the same. A drug-coated balloon catheter for delivering a therapeutic agent to a target site of a body lumen stricture includes an elongated balloon having a main diameter. The balloon catheter includes a coating layer overlying an exterior surface of the balloon. The coating layer includes one or more water-soluble additives and an initial drug load of a therapeutic agent. In some embodiments, the balloon catheter includes a length-control mechanism which stretches and elongates the balloon when it is in a deflated state, giving the balloon a smaller cross-sectional deflated profile for tracking through the body lumen and for removal after treatment.

Systems and methods for processing electronic images from a medical device comprise receiving an image frame from the medical device, and determining a first color channel and a second color channel in the image frame. A location of an electromagnetic beam halo may be identified by comparing the first color channel and second color channel. Edges of an electromagnetic beam may be determined based on the electromagnetic beam halo, and size metrics of the electromagnetic beam may be determined based on the edges of the electromagnetic beam. A visual indicator on the image frame may be displayed based on the size metrics of the electromagnetic beam.

The present disclosure provides an endoscopic surgery apparatus that includes an insertion tube having a passage formed inside, and that is to be inserted into a patient's urethra; a laser part that is installed such that it can reciprocate in the passage, and that separates a prostate adenoma from a patient's prostatic capsular surface; a hemostasis part that is installed such that it is spaced apart from the laser part and can reciprocate in the passage, and stops bleeding of a bleeding blood vessel of the patient's prostatic capsular surface; a camera part that is located in the passage and that photographs inside of the patient's prostate; and a transfer part that selectively transfers the laser part and the hemostasis part.
