An intraurethral magnetic valve having an inlet port and an outlet port, the valve including: a valve main body; a ferromagnetic ring located at least partially within the valve main body; a valve seat; and a magnetic valve element located within an internal volume defined by the valve main body and configured for movement with respect to the ferromagnetic ring, that movement being within the valve main body between a closed configuration in which fluid is inhibited from flowing from the inlet port through the outlet port and an open configuration in which fluid is permitted to flow from the inlet port through the outlet port, movement of the magnetic valve element being on exposure to a magnetic field from an external magnet member, wherein the valve seat is formed from an elastomer material.

Provided is a ureteral stent for placement in a bladder, a kidney and a ureteral passageway connecting the bladder and the kidney. The ureteral stent includes a solid bladder portion free of a lumen positionable in the bladder, a tubular kidney portion positionable in the kidney and the ureteral passageway, and a tether connecting the bladder portion and the ureter portion to allow the bladder portion to float in the bladder and to allow a ureter orifice connecting the ureteral passageway to the bladder to move between a compressed state and an uncompressed state. By not having a lumen, the solid bladder portion allows the bladder to have a smaller diameter while maintaining a necessary uncoil force. The smaller diameter also allows the bladder portion to be inserted into a scope alongside a pusher tube, thereby avoiding loading the bladder portion onto a guidewire.

The present disclosure relates generally to controlled extension medical stents, and more particularly to controlled extension devices positioned in the body to stent the ureter and facilitate drainage from the kidney to the bladder.

A ureteral stent that includes a tubular member and a retaining end adapted to be placed inside a kidney or a bladder of a patient. The retaining end includes a plurality of loops. Each of the loops are centered about a loop axis, and two or more of the loop axes extend in different directions relative to other loop axes.

A stent is provided that includes a body extending between a distal and a proximal end. The body is defined by a plurality of elongated members, with each elongated member extending between a distal end that is coterminous with the distal end of the body and a proximal end that is coterminous with the proximal end of the body. Each of the plurality of elongated members are arranged so as to define a lumen extending along the length of the respective plurality of elongated members, the lumen extending between the distal and proximal ends of the body so as to form a lumen length. Each of the plurality of elongated members are configured to permit drainage of a fluid from within the lumen to an environment external the stent along the entire lumen length.

A packaging system for use with a ureteral stent having an elongated shaft extending between a proximal end portion and a distal end portion may include a tray base. The tray base may include at least one first post, a second post, and a projection or a groove configured to respectively secure the distal end portion, the proximal end portion, and a tether of the ureteral stent on the tray base.

An adjustable length medical device, such as a drainage stent, and delivery device for placing within the body, having an elongate tube and retention members at each end portion for anchoring the device in the body. The proximal portion of the device including the proximal retention member may be segmented in incremental portions so that the length of the device can be adjusted for placement.

A catheter device and manufacturing process for manufacturing the catheter device, wherein the catheter device has a halo-shaped coiled portion extending away from a perpendicular stem portion through a swan neck portion. Eyelets on the halo coil portion and swan neck portion facilitate flow out of the bladder through the catheter device vertical to the catheter, rather than perpendicularly as is the case with existing catheters. The catheter device is formed by using a straight catheter tube, heating and cooling it within a formed mold to have the halo coil and swan neck, such that it can be straightened using a pusher and stylet, inserted into the body while straightened, and thereafter return to its coiled shape when the stylet is removed.

An intermittent-catheter assembly (100) includes an intermittent catheter and a catheter housing (102). The intermittent catheter includes a funnel and a catheter tube fluidly coupled to the funnel. The catheter housing (102) includes the intermittent catheter disposed in the catheter housing while in a packaged state of the intermittent-catheter assembly. The catheter housing includes an inner sleeve (104) and an outer sleeve (102). The inner sleeve (104) includes a longitudinal cavity containing a majority of the intermittent catheter in the packaged state of the intermittent-catheter assembly. The outer sleeve (106) is slidably disposed over the inner sleeve (104). The catheter housing (102) is configured to expose the intermittent catheter for removal from the catheter housing (102) when the outer sleeve (106) is grasped and slid toward an exposed end of the inner sleeve (104) in opposition to a force applied to the exposed end of the inner sleeve (104).

The present disclosure relates generally to devices, systems, and methods for extracting ureteral stent from a patient. Some embodiments are particularly directed to an extraction tool capable of extending into a urethra and retrieving a stent without scope visualization, assistance from a medical professional, and/or prescription medication (e.g., for pain). The extraction tool may be a single-use tool having an end effector configured to capture a proximal portion of a stent. In several embodiments, the extraction tool be utilized in conjunction with a stent assembly having a band coupled to a proximal retention member of the stent.
