An application device has a ureteral catheter with a ureteral catheter main body, a receiving body connected to the ureteral catheter main body by means of at least one connection element of the ureteral catheter, and an introduction component for holding the ureteral catheter and for guiding the ureteral catheter through a ureter of a patient along a pliable guide element. The ureteral catheter can be displaced by means of the introduction component in opposite directions of movement along the pliable guide element and the introduction component is designed to guide the ureteral catheter main body and the receiving body during displacement in the respective directions of movement.

In a connective-tissue body according to an embodiment of the present disclosure, comprising a biological tissue including collagen, a fine surface layer formed more finely than the inside thereof is provided on the surface of the connective-tissue body.

Methods and devices for treating a luminal pathology affecting an anatomical lumen of a patient comprising forming, in situ, a continuous cohesive layer of covalently-crosslinked hydrogel in a luminal wall of the anatomical lumen.

A ureteral stent is provided. The stent may include a first section having a first wall defining a first luminal section. The stent may further include a second section having a second wall defining a second luminal section. The second section can be enabled to substantially close at times external pressure is applied to the stent.

This document relates to methods and materials for treating urinary calculi. For example, ureteral orifice devices and methods for using ureteral orifice devices to treat urinary calculi present within a mammal (e.g., a human) are provided.

A percutaneous urinary catheter is provided, including a proximal portion, a distal portion configured to be deployed in a kidney and/or renal pelvis of the urinary tract, and at least one lumen extending at least partially through the proximal portion of the percutaneous urinary catheter; and a negative pressure source in fluid communication with the at least one lumen, the negative pressure source being configured to draw fluid from the urinary tract into the at least one lumen of the percutaneous urinary catheter for removal of the fluid from the urinary tract.

Disclosed herein are methods, devices and compositions for degradable medical devices and/or compositions that provide local and/or systemic delivery of at least one active agent.

Apparatus and methods are described for treatment of a urethra that is constricted due to benign prostatic hyperplasia (BPH). A positioning device is used to determine a location of the area of the urethra that is constricted and is to be treated. An execution device includes a dilation balloon, a cutter, an implant carrier, and an implant, the implant and the implant carrier both being disposed outside the outer surface of the dilation balloon. The urethra is dilated by expanding the dilation balloon, and a cut is formed in the inner surface of the urethra using the cutter. The implant is released into the cut within the inner surface of the urethra subsequent to the cutter forming the cut in the inner surface of the urethra, to thereby maintain the urethra in a dilated state. Other embodiments are also described.

Provided is a ureteral stent including a bladder portion positioned in a bladder of a patient, a kidney portion positioned in a kidney and ureteral passageway of the patient, and one or more tethers coupling the bladder portion to the kidney portion. The ureteral stent allows urine to pass around a blockage, and allows a ureter orifice connecting the ureteral passageway to the bladder to move between a compressed state and an uncompressed state to prevent or minimize urinary reflux, flank pain, blood in the urine, etc., while allowing the bladder portion to move freely in the bladder to prevent the bladder portion from irritating the trigone muscle.

A ureteral stent may comprise an elongate member with an internal-luminal space. The member may have at least one end coiled in a pigtail-shape, a substantially straight portion, and a plurality of side ports wherein the plurality of side ports are located only in the substantially straight portion and are disposed along a spiral or helix where each side port is located radially and longitudinally offset relative to each adjacent side port.
