Placement of a stent having a tethered ferromagnetic bead may be facilitated with a modified pusher having an opening at the distal end of the pusher to receive the tethered ferromagnetic bead. The ferromagnetic bead may be positioned within the bladder whereby a tether connection to a shortened stent ending within the ureter may be used to reduce the likelihood of patient irritation. The bead, tether, and stent assembly may be advanced into the patient as a unit along a conventional guide wire and using a conventional cystoscope.

A method for removing a stone from a patient comprising the steps of: providing a suction evacuation assembly which includes a sheath and one or more side arms; inserting and positioning a distal end of the sheath into a lumen or cavity of a patient's body containing a stones; connecting a tube to one of the side arms and to a collection bottle; connecting another tube to the collection bottle and a negative pressure system; visualizing the stone or foreign body using a scope inserted through the assembly; activating the negative pressure system in order to remove the stone from the cavity if the diameter of the stone is narrower than an inside diameter of the sheath and the side arm, or performing a lithotripsy on the stone to create fragments with a decreased diameter which allow the passage through the assembly; and collecting the stone in the collection bottle.

Biliary diversion catheters for diverting bile fluid from a part of the patient's biliary tree to the patient's distal small intestine. The catheter comprises a system of interconnected or interconnectable tubes: a biliary tube segment, an intestinal (e.g. ileal or jejunal) tube segment, and a flush tube segment. The biliary diversion catheter is designed such that bile fluid flows into the biliary tube segment and is shunted into the distal small intestine via the intestinal tube segment. The flush tube segment is used to infuse flush fluid into the catheter (e.g. to clear out any debris within the tube system of the catheter). The biliary tube segment and the intestinal tube segment may together form a drainage tube or an anastomotic component. The flush tube segment and the intestinal tube segment may together form a transabdominal tube.

[Subjects] To provide a biliary tract drainage tube in which both an external drainage tube and an internal drainage tube can be installed in a single endoscopic procedure.

[Method to Solve]

A biliary tract drainage tube used to drain a biliary tract is provided with long external drainage tube 2 and internal drainage tube 3 that is provided on the tip of the external drainage tube so as to be separable from the external drainage tube. Both external drainage tube 2 and internal drainage tube 3 are placed in biliary tract Cd. Since internal drainage tube 3 can be left behind in the biliary tract by removing external drainage tube 2, another endoscopic procedure is not required when switching from external drainage tube 2 to internal drainage tube 3, and the burden placed on the patient can be lessened.

A device for implantation in a body may include a body defining a lumen. The body may have a first end and a second end, and the lumen may define a central axis. The body may include a first flexible flange having a first base portion and a first angled portion. The first base portion may be about perpendicular to the central axis and extend radially away from the first end. The body may further include a second flexible flange having a second base portion and a second angled portion. The second base portion may be about perpendicular to the central axis and extend radially away from the second end. The first and second angle portions may be generally angled toward each other. A loading device may be configured to load the device into a delivery device. The delivery device may be configured to delivery and deploy the device.

The present disclosure relates to the field of body lumen drainage. Specifically, the present disclosure relates to implantable medical devices for facilitating the flow of fluids and materials between adjacent body lumens. In particular, the present disclosure relates to a drainage stent which maintains an open flow passage between fused tissue layers.

Devices, methods, and kits are presented that allow for simplified stent placement and stent retention in a biological vessel other than a blood vessel, and especially biliary stent placement in an antegrade manner. The devices and methods advantageously allow for shortened imaging and stent placement time, and substantially improve tolerability and/or retention of the stent in the vessel, and in further beneficial aspects, contemplated stents form a composite fluid path to facilitate drainage of the vessel. Still further, the devices and methods presented herein reduce or even entirely eliminate partial deflation of the peritoneal space during imaging and stent placement and so prevent exposure of operating personnel to vented gases carrying harmful agents.
