A device and method for treatment of urinary stress incontinence. At least one electrode is implanted in a pelvic muscle of a patient. A control unit receives signals indicative of abdominal stress in the patient and responsive thereto applies an electrical waveform to the electrode which stimulates the muscle to contract, so as to inhibit involuntary urine flow through the patient's urethra due to the stress.

A magnetic actuation urethral valve is adapted for inserting into the urethra of a patient who suffering from urinary incontinence in order to recover control of urine flow. The valve member is driven by a magnet rotor which is magnetically actuated by a rotating magnetic field generated from a controller outside the body. There is also an actuation device for the user to discharge by inserting an indwelling catheter into the valve in case the valve does not work for any reason.

The present invention comprises a plurality of injectable hollow particulate fillers suspended in a biocompatible fluid carrier to significantly improve the clumping resistance and injectability of the composition. The hollow particulate fillers have a lower effective density and are able to suspend in the carrier without precipitation. The loss of skin volume as a result of aging, diseases, weight loss, and injury can lead to uneven skin surface (e.g. wrinkle, etc.). The uneven skin can be repaired by injecting appropriate amount of hollow fillers underneath the skin. Some cases of urinary incontinence occur when the resistance to urine flow has decreased excessively. Continence is restored by injecting the present invention to the urethra tissue to increase resistance to urine outflow. Similarly, the present invention allows for the control of gastric fluid reflux by submucosal injections of the fillers to the esophageal-gastric and gastric-pyloric junction. For patients with vesicoureteral reflux, it can be treated by injection of the present invention into patients' ureteral tissue. This invention can also be used to repair defective or inadequately functioning muscles of the anal sphincter by administering an effective amount of injectable hollow fillers into the defect or anal sinuses.

In use, the catheter is installed in a patient, the third lumen is filled with a pressure transmitting medium, connected to a pressure sensor, and the patient's intra-abdominal pressure is monitored without interruption of the urine flow.

Methods for increasing urine flow are disclosed, comprising administration of an effective amount of GLP-1, an exendin, or an exendin or GLP-1 agonist. Methods for increasing urinary sodium excretion and decreasing urinary potassium concentration are also disclosed. The methods are useful for treating conditions or disorders associated with toxic hypervolemia, such as renal failure, congestive heart failure, nephrotic syndrome, cirrhosis, pulmonary edema, and hypertension. The present invention also relates to methods for inducing an inotropic response comprising administration of an effective amount of GLP-1, an exendin, or an exendin or GLP-1 agonist. These methods are useful for treating conditions or disorders that can be alleviated by an increase in cardiac contractility such as congestive heart failure. Pharmaceutical compositions for use in the methods of the invention are also disclosed.

A method and apparatus is provided for heating or cooling at least a selected portion of a patient's body. The method begins by inserting a catheter through the urethra and into the bladder of the patient. A heated or chilled fluid is conducted through a supply lumen of the catheter and into the bladder. The fluid is evacuated from the bladder through a return lumen of the catheter. Finally, a quantity of urine is monitored which flows out of the bladder and through the return lumen of the catheter. The rate of fluid flowing through the supply lumen of the catheter may be adjusted in a manner that is based at least in part on the monitored quantity of urine flowing out of the bladder.

An automatic urine disposal device has a urine collecting pad, vacuum pump, and urine tank. In the urine collecting pad, the top sheet comes in contact with the wearer's skin, the hydrophilic sheet is disposed on the bottom of the top sheet, and the urine absorbent sheet is disposed at the bottom. When discharged urine flows in the top sheet, the hydrophilic sheet widely diffuses urine to saturate its entire surface and then becomes non-breathable. As the vacuum pump vacuums the air from the urine tank, urine is directed from a urine drainage port of the urine collecting pad via a urine drainage tube to the urine tank which is a sealed container.

An indwelling catheter is positioned in a urinary tract to drain urine from the bladder to a position distally adjacent to a sphincter muscle. A balloon of the catheter is inflated through an inflation tube extending through the urinary tract. A coiled section of the inflation tube contacts the constriction caused by the sphincter muscle. The balloon and the coiled section resist movement of the indwelling catheter while still permitting natural urination. The indwelling catheter is inserted by an insertion tool which is separably connected to the catheter. Once the indwelling catheter is positioned, the tool is disconnected and withdrawn from the urinary tract. Risks of blood clots obstructing the flow of urine through the indwelling catheter immediately following a surgical procedure on the prostate gland are avoided by flushing fluid through the insertion tool and the catheter to clear an internal urine flow passageway in the catheter.

The present invention provides a method and apparatus for maintaining urine flow during and after urological procedures. The invention includes a stent for long term insertion into a patient's urinary tract, a Foley catheter which is used to support the stent during placement, a positioning shaft which is used to position the stent with respect to the catheter, and a protective sheath that retains these components in place during insertion of the stent. Alternatively, a Foley catheter with two balloons may be used in place of the stent positioner, with the stent being accurately positioned with one of the two balloons being surrounded by the stent.

The disclosed system improves urine flow by increasing the inside diameter of the urethra going through the prostate by eroding the urethral wall, rather than by reducing the prostate volume. This is done by a specially designed IRE electrode, which limits the penetration depth of the electric field to the urethral wall.

The present disclosure generally pertains to a device and system for preventing urinary backflow into the urinary tract of a patient. The device comprises a one-way valve which allows for unobstructed urine flow in the direction of the urine towards the urine collection container and away from the catheter. The device prevents backflow into the catheter in situations where the urine collection container is raised above the level of the bladder. The components on the exit side of the valve are coated with an antimicrobial substance to prevent bacterial contamination of the system. The exit volume also contains a silver coated high surface area element to serve as an antibacterial kill site. The inlet side of the device has a volume and access port for urine sampling, with a one-way valve element providing isolation from contamination from the urine collection system.

The invention emulates the operation of a healthy urethra by providing a valve with a large differential between the opening pressure and the closing pressure. The differential is achieved by using a snap action created by the action of the urine flow on a force that drops off rapidly with displacement. A preferred way to achieve such as force is by using permanent magnets. The valve is installed simply by insertion into the urethra and can easily be removed. No surgical procedure is involved.

A multi-piece fluid transfer receptacle is used in a male incontinence device. The receptacle includes an outer shell having a first open end adapted for receiving the penis of a user and a second end defining a fluid discharge port.
