The subject invention teaches the use of electrical stimulation of specific sensory nerves, such as the proximal urethral afferents to control urination. A wireless, injectable microstimulator may implanted into the soft tissues through which the sensory nerves pass. The sensory nerves supplying the proximal urethra are stimulated by a microstimulator implanted adjacent to the prostatic urethra within the substance of the prostate gland in males, and distal to the bladder neck in females. The activity induced in these nerves causes the spinal cord to generate reflex responses that result in contractions of the detrusor muscle and relaxation of the sphincter, emptying the bladder. The invention also includes methods of implanting and/or testing microstimulators at a target location. The invention also includes the use of sensory devices to effect the microstimulators or alert the user as to the status of the bladder.

Urine collection apparatus is provided which can be used to assist bedridden and/or incontinent patients, particularly female patients. The apparatus includes a urine collector which is shaped for location against the perineal region of a patient adjacent the urethra. The urine collector comprises a hollow body having opposed ends in which an inlet for air and an outlet for air and urine are formed, respectively. The body has a central region between the end regions with a reduced cross-sectional area. This effectively creates a venturi adjacent the patient's urethra when air passes through the collector. The apparatus includes a urine receptacle with an inlet for receiving air and urine from the collector, and an outlet for air which is connectable to a source of low pressure. The source of low pressure will typically be an impeller driven by an electric motor, which creates a sufficiently strong air flow through the apparatus to entrain urine and transport it to the receptacle.

Disclosed are methods for treating urinary incontinence in a mammal wherein a composition comprising a biocompatible polymer, a biocompatible solvent, and a contrast agent is delivered to the periurethral tissue of the mammal.

The invention belongs to the field of medical equipment, particularly relates to urinary surgery calculus grabbing equipment capable of preventing infection, and provides the following scheme aiming at the problems that in the using process of existing grabbing equipment, the using length is inconvenient to adjust, calculus is inconvenient to protect, the urethra is prone to being damaged and infected, and the treatment effect is reduced. The device comprises a shell, a first sliding groove is formed in one side of the shell, a sliding column is slidably mounted in the first sliding groove, a connecting plate is fixedly connected to one side of the sliding column through welding, a second sliding groove is formed in the other side of the shell, a mounting plate is slidably mounted in the second sliding groove, a first through hole is formed in the mounting plate, and a grabbing mechanism is arranged on the mounting plate; in the use process, the use length can be conveniently adjusted, calculi can be conveniently protected, the urethra can be prevented from being injured and infected, the treatment effect is improved, and the urethra dilator is simple in structure and convenient to use.

The invention discloses a transurethral ureter hard convection negative pressure channel lithotripsy and lithotripsy device which comprises a ureter hard mirror and a negative pressure suction pipe, two arc-shaped clamping plates are slidably connected to the outer side of the end, away from the ureter hard mirror, of the negative pressure suction pipe, and two first sliding grooves are formed in the ureter hard mirror and the negative pressure suction pipe correspondingly; and an extrusion mechanism used for extruding the arc-shaped clamping plates and enabling the two arc-shaped clamping plates to be far away from each other when the arc-shaped clamping plates are extruded is arranged in the first sliding groove. When large broken stone is encountered, the moving plate is pushed to drive the first extrusion plate to move in the first sliding groove, when the first extrusion plate extrudes the arc-shaped clamping plates, the arc-shaped clamping plates move in a second sliding groove, the two arc-shaped clamping plates are far away from each other, and when the distance between the two arc-shaped clamping plates is increased, boken stones can be accommodated in the device, so that the urethra is prevented from being hurt by larger broken stones or sharp parts of the broken stones.
