The invention provides a method and system for treating disorders in parts of the body. A particular treatment can include on or more of, or some combination of: ablation, nerve modulation, three-dimensional tissue shaping, drug delivery, mapping stimulating, shrinking and reducing strain on structures by altering the geometry thereof and providing bulk to particularly defined regions. The particular body structures or tissues can include one or more of or some combination of region, including: the bladder, esophagus, vagina, penis, larynx, pharynx, aortic arch, abdominal aorta, thoracic, aorta, large intestine, sinus, auditory canal, uterus, vas deferens, trachea, and all associated sphincters. Types of energy that can be applied include radiofrequency, laser, microwave, infrared waves, ultrasound, or some combination thereof. Types of substances that can be applied include pharmaceutical agents such as analgesics, antibiotics, and anti-inflammatory drugs, bulking agents such as biologically non-reactive particles, cooling fluids, or dessicants such as liquid nitrogen for use in cryo-based treatments.

A method is provided for local controlled delivery of a drug to the seminal vesicle, the prostate, the ejaculatory duct, or the vas deferens of a patient in need of treatment. In one embodiment, the method includes implanting a resorbable drug delivery device within the seminal vesicle, the prostate, the ejaculatory duct, or the vas deferens of the patient. The drug delivery device may include an elastic device body housing at least one drug reservoir which contains at least one drug. In a preferred embodiment, the method further includes releasing the drug from the device in a controlled manner to, typically directly to, the seminal vesicle, the prostate, the ejaculatory duct, or the vas deferens.

Methods for the synthesis and use of several variations of styrene maleic acid-based polymers and the hydrogel tissue bridges that can be formed from such polymers. Specifically, a method is disclosed for synthesizing a styrene maleic acid-based polymer that can be dissolved in DMSO and injected into the vasa deferentia of male subjects, creating a hydrogel tissue bridge. This hydrogel tissue bridge can occlude the vas deferens, thus forming an effective male contraceptive. Additionally, this male contraceptive can be reversed by injecting the lumen of the vas deferens with a basic buffer solution to dissolve and remove the hydrogel tissue bridge.

Disclosed are methods of delivering an agent to the lumen of the vas deferens under guidance of ultrasound imaging. The methods include vas-occlusive contraception in which the vas deferens is non-surgically isolated and an occlusive substance is percutaneously administered into the lumen of the vas deferens under ultrasound. Also disclosed are methods of reversal of vas-occlusive contraception and methods of delivering an agent to the lumen of the vas deferens. Also disclosed are compositions for use in the methods of the invention.

There is provided a method for controlling a flow of fluid in the vas deferens in order to obtain a controlled male contraception. The method comprises gently constricting (i.e., without substantially hampering the blood circulation in the tissue wall) at least one portion of the tissue wall to influence the flow vas deferens, and stimulating the constricted wall portion to cause contraction of the wall portion to further influence the flow in the vas deferens. The method can be used for restricting or stopping the flow in the vas deferens, or for actively moving the fluid in the vas deferens, with a low risk of injuring the organ.

Described are restraints, and methods of using and making the restraints, for restraining a man's testicular retraction response to sexual stimulation. It is believed that the restraints and methods of use thereby tend to slow or postpone the onset of the man's climax, with the potential to prolong the pleasure of the man and / or his sexual partner. More particularly, clip restraints and loop restraints are described and illustrated. The clip restraints are configured to grip a portion of the scrotum and to present deflection or obstruction features above the reposed positions of each of the man's testicles, configured to deflect or obstruct the movement of the testicles toward a retracted position associated with the onset of the man's sexual climax. Advantageously, clips according to the invention may fold to a narrow thickness, convenient for carrying in a pocket or wallet. Clip members of the restraints may be attracted by magnets, biased by springs, or manually adjusted to a stable gripping position. The loop restraints comprise left-hand and right-hand loops configured to extend around a portion of the scrotum and to define a restraint opening, confining at least a restrained portion of the respective testicle to one side of the restrained opening to limit retraction of the respective testicle through the opening in a direction toward the respective vas deferens.
