A rod-like or tube-like sphincteric closure device is micro-invasively implanted beneath the surface of the posterior mucosal wall to elevate the mucosa and close the lumen, by using a delivery device operated through the urethra. To initiate voiding, the muscle-rich anterior urethral wall contracts and widens the lumen beyond the closing or elevating range of the sphincteric closure device. For urethral obstruction, repelling magnets are micro-invasively implanted beneath the surface of mucosa with the delivery device through the urethra, to widen the lumen with magnetic force.

An implantable device for the treatment of acid reflux disease has a body including an outer surface adapted to rest against a patient's fundus wall. The device, when implanted in a patient, fills a volume in the patient's abdomen in the cardia area and above the cardia of the patient, when standing. The body prevents the cardia from moving through the diaphragm opening into the thorax, thereby preventing reflux by keeping the abdominal pressure supporting the cardia sphincter muscle. The device may be affixed to stomach tissue. The device may also be invaginated or otherwise indirectly secured in position.

A variety of passive intragastric implant devices for obesity treatment are disclosed. Such passive devices do not autonomously change shape, but instead react within the stomach to induce satiety. The devices may take up volume within the stomach, thus reducing the intake capacity. Additionally, the devices may contact areas within the stomach, such as the cardia surrounding the esophageal sphincter, or the greater and lesser curvatures in the middle of the stomach, to stimulate satiety-inducing nerves. Some devices may combine two or more of these satiety-inducing features. Methods of implant are disclosed including compressing the devices within a delivery tube and transorally advancing the devices through the esophagus to be deployed within the stomach. Removal of the devices occurs in the reverse.

A method and apparatus for minimizing fecal incontinence in a subject, is disclosed. An inhibition action incontinence device includes a truncated cone with an angled concavity at a top portion. The truncated cone is positioned at the external opening of the anal canal. The truncated cone may be positioned to effect a positive pressure on the external sphincter muscles and the anal slit across the peri-anal tissues. It is believed that the truncated cone exploits the voluntary inhibition action of the external sphincter muscles and the simple mechanical closure of the anal slit to decrease fecal incontinence and soiling.

The invention provides a system and a method of eliciting milk from all mammals that possess teats, including but not limited to dairy animals and humans. A system may be comprised of an elastic system and a vacuum supply. A method may include a milk elicitation system comprised of an elastic system and a vacuum supply. Through the application of vacuum, the elastic system forms, differentiates, seals and adapts to a teat, from the area it ends until up to where the udder ends and it begins, without coming in contact with the teat-end sphincter/lactiferous duct(s). The elastic system interacts proportionately according to the tendencies expressed by teat physiology and dynamics according to the milk pressure change, blood flow, and the effects of applied vacuum, throughout the milk elicitation process, resulting in continuous and complete milk elicitation and supporting the physiological teat return, after the process.

The present invention relates to a cell therapy product which is intended for regenerating a sphincter muscle and which contains stem cells derived from amniotic fluid, and more particularly, to a cell therapy product which is intended for regenerating the sphincter vesicae and which contains stem cells derived from amniotic fluid.
