An artificial urethral sphincter. The artificial urethral sphincter includes a cuff member, a hollow cylinder, a spring, and a cable. The cuff member includes a first layer and a second layer, which define an internal pocket between the first layer and the second layer. The cuff member is configured to encircle a urethra of a patient when the cuff member is wrapped around the urethra of the patient. The hollow cylinder is configured to be disposed inside the patient's body. The spring is disposed inside the hollow cylinder. A first part of the cable is disposed inside the internal pocket. The first part of the cable is configured to block the urethra of the patient through gripping the urethra of the patient when the first part of the cable is pulled out of the internal pocket.

A device, system, and method for closing and reopening a sphincter in a body, such as for closing and opening an internal urinary sphincter of a bladder, thereby blocking retrograde ejaculation, by employing controllable electromagnets. Using the present device, system, and method, the patients can selectively close their bladder's sphincter as desired, for example, to selectively block retrograde ejaculation, preventing semen from entering the bladder of the patient and thereby preventing infertility of the patient. The solution helps regain the elasticity function of the sphincter to allow it to close as per normal to prevent retrograde ejaculation. A series of magnetizable metal objects are positioned in or surrounding the bladder wall at the junction with the urethra, with each of the magnetizable metal objects being electromagnetically controlled to have a controllable closing/reopening of the bladder's sphincter, thereby preventing retrograde ejaculation while also allowing the passage of urine as per normal.

The present invention relates to a urinary incontinence clamp device for men utilizing magnetic force and, more particularly, to a urinary incontinence clamp device for men characterized in that, as a second clamp unit slides along an inner surface of a first clamp unit, the penis is gradually secured by a penile fixing portion, whereby the force applied to the penis is gradually exerted, reducing impact force applied to the penis, and thereby improving wearing comfort by preventing pain in the penis during fixation.
