Abstract: A medical instrument for insertion into and removal of kidney stone fragments from a urinary tract of a patient body includes a flexible elongate shaft coupled with a fragment retaining mechanism. The retaining mechanism can be configured to retain a plurality of fragments so that the plurality of fragments is removed from the patient with a single insertion/extraction cycle of the instrument. A fragment gathering mechanism urges fragments toward the retaining mechanism. In use, the instrument can be inserted through a working channel of a ureteroscope.

Abstract: A drainage liquid sampling system is disclosed and includes a connector couplable with a drainage tube of a drainage system, the connector defining an inlet port, an outlet port, and a sample port, where the inlet port, the outlet port, and the sample port are in fluid communication with each other, and a sample container couplable with the sample port. A valve within the connector selectively allows and prevents flow of drainage liquid into the sample container. A cap couplable to the sample container also includes a valve. A system for draining liquid from a patient includes the drainage liquid sampling system.

Abstract: Disclosed herein is a urinary output monitoring system configured to measure urinary flow or collect and measure a volume of fluid having a receptacle having a receptacle body including a plurality of volume markings, the receptacle configured to receive or hold a volume of fluid. The receptacle body includes a proximal portion including two lateral flaps and one front rigid flap, each of the flaps extending from the proximal portion, the two lateral flaps and the front rigid flap configured to secure the receptacle to a sanitary hardware device and prevent unwanted movement when engaged by a user, and a distal portion including an opening and a mating portion extending from the distal portion, the mating portion configured to detachably couple an attachment.
