4 results about "Artificial sphincter" patented technology

A cuff for use an as artificial sphincter includes an inflatable chamber and a backing. The inflatable chamber includes opposing inside and outside surfaces and inflated and deflated states. The backing is adjacent the outside surface of the chamber. The inside surface of the chamber includes two or more grooves that define the location of fold lines of the inflatable chamber when the inflatable chamber is in the inflated state. The inflatable chamber and backing are configured to surround a duct of a patient with the inside surface of the chamber facing the duct and the grooves extending substantially parallel to the duct.

The invention relates to an artificial anal sphincter system based on defecation perception. The artificial anal sphincter system comprises a defecation perception module, a driving module, an execution module, a control circuit and a single-chip microcomputer control module. The defecation perception module comprises a sensor, an alarm module and a screen display module; the defecation perception module, the driving module and the execution module are all connected with the control circuit. When the patient needs to defecate, the execution module controls the clamping mechanism to release the rectum, and normal defecation is carried out; after defecation is finished, the execution module clamps the rectum again, and the sensor replaces normal rectal nerves. Compared with the prior art, the device simulates the contraction mechanism of the sphincter, the movement of the upper clamping plate and the lower clamping plate acts on the intestinal canal, the closed state of the intestinal canal tissue is simulated, a complex mechanical structure is avoided, the effectiveness of the artificial sphincter is improved, the defecation sense sensing function of the rectum and the sphincter group is remodeled, and the practicability is higher.

An implantable device for adjusting fluid flow through a bodily lumen, comprises a cuff configured to be positioned around the lumen; an actuator; a connection part connecting the cuff and the actuator; and an induction coil configured to generate an induced current in response to a transcutaneous magnetic induction, wherein the actuator is configured to operate the cuff by transitioning the cuff between a deployed state and an undeployed state in response to the induced current. In some embodiments, the device further comprises an alternative actuation mechanism that includes a magnet assembly configured to rotate and cause the transition of the cuff between the deployed state and the undeployed state. Further, in some embodiments, the transcutaneous magnetic induction is generated by an external inducer configured to induce a temporally varying magnetic flux in the coil to generate the induced current.

The utility model discloses an artificial sphincter capable of controlling opening and closing relates to postoperative auxiliary instrument. This artificial sphincter capable of controlling opening and closing, including implanting annular part of stoma and the plunger body that can be inserted or taken out from annular part. When plunger body inserts the annular part of implanting stoma, can realize the closure of stoma. After plunger body pulls out, can realize the opening of stoma, make the excretion activity of postoperative user change from uncontrolled to controllable state. In addition, still can set up pressure sensor in plunger body, can monitor the pressure change inside large intestine, and prompt patient defecation signal. Set up pressure sensor at the magnetic attraction part of plunger body to monitor the pressure of the mutual attraction of magnetic attraction part and annular part to large intestine wall, to prevent the pressure from being too big, lead to the influence to large intestine blood circulation. The utility model discloses simple operation has solved the problem that postoperative patient who loses sphincter function excretion is not controlled, has improved the life quality of postoperative patient.
