Abstract: The present disclosure provides a trapping device for trapping microbes, the device comprises a porous polymeric structure with a proximal end and a distal end, wherein the proximal end and the distal end is optionally provided with a hole or core on the 5 longitudinal direction. The present disclosure also provides a process of preparing the device and implementations thereof.

Abstract: The embodiments disclosed herein relate to a ureteral stent having two stent bodies and a tether. The stent can minimize or prevent migration of the device out of the bladder of the patient while also reducing patient discomfort associated with such stents.

Abstract: In one aspect, a method of treating or preventing kidney stones in a patient is provided. A therapeutically effective amount of a compound or a pharmaceutically acceptable salt, solvate or hydrate thereof which induces glucosuria or a pharmaceutical composition thereof is administered to the patient in need thereof.

Abstract: This invention provides a novel surgical device well suited to use in laparoscopic or other (e.g. open surgical) procedures. In certain embodiments, the device comprises a surgical probe, including a handle comprising at least one channel passing through the handle; and at least one conduit passing through the handle, where wherein at least one effector element is inserted into or through the channel, which effector element effects one or more surgical functions; and where the conduit comprises a distal conduit port that directs gas out of the conduit to substantially remove debris and/or fluid from a surface disposed proximal to the effector and/or from the effector element.

Abstract: Active and passive wound drainage systems and method are provided. A drainage device includes an input passage for receiving the fluid from a site on or within the patient's body, a container for holding the fluid, and a reversible valve disposed between the input passage and the container. The reversible valve in an original configuration provides unidirectional fluid flow from the input passage toward the container, and in a reversed configuration provides fluid flow from the container toward the input passage.

Abstract: This invention provides a drainage device for biological fluids. The device typically comprises a port for attachment of the device to a catheter or to a waste collection device; and a means for applying a negative pressure to said port, wherein said negative pressure is an intermittent substantially constant negative pressure.

Abstract: This invention provides improved medical drainage devices. In certain embodiments this invention provides a system for improved drainage from a bladder in a patient where the system comprises: a fluid collection apparatus; a drainage receptacle; and a connecting tube comprising a means for reducing or eliminating airlocks in the connecting tube and thereby providing sufficiently low backpressure such that a patient having a urinary bladder drained with said system maintains an average residual bladder urine volume of less than about 50 cubic centimeters over a period of at least four hours after initial drainage without manipulation of components of said system.

Abstract: An instrument for extracting stones from the urinary tract of a patient comprising a urological catheter (12) and a stone-extracting basket (26) formed from resilient wires and slidingly inserted into catheter (12). The instrument has a drive unit (18) which is connected to the basket via a rod (22). Drive unit (18) transmits to the rod rotation and axial vibrations, which in turn are transmitted to the basket. When rod (22) rotates, curved portion (21) generates radial vibrations which are transmitted to the basket. In order to prevent basket (26) from rotating, but to transmit to it only axial and radial vibrations, rod (24) is connected to basket (26) through a spherical joint (42). On its front end the basket has a filiform (38) which facilitates insertion of the instrument into the urinary tract. In use, after insertion of the catheter to a position in which the basket is aligned with the location of the stone, the basket is released from the catheter and expands.
