The invention relates to an occlusion system implantable in a human or animal body, comprising: a fluidic circuit comprising: an inflatable occlusive sleeve (3), a reservoir (5) with variable volume filled with a fluid, said reservoir comprising a fixed portion and a movable portion, an actuator mechanically coupled with the movable portion of the reservoir so as to linearly displace said movable portion relatively to the fixed portion for adjusting the volume of the reservoir, the actuator and the reservoir with variable volume being laid out in a sealed casing (1) containing a gas, a sensor (21, 22) mechanically bound to the actuator and/or to the movable portion of the reservoir, measuring a traction and/or compressive force in the direction of displacement of the movable portion of the reservoir, a device for measuring the fluid pressure (P1) in the fluidic circuit taking into account at least the force measured by said sensor (21, 22), the effective pressure surface area (S.sub.eff) of the movable portion of the reservoir, and the force exerted on the movable portion of the reservoir with variable volume related to the pressure of the gas in the casing.

A medical implant system for implantation in a patient to treat erectile dysfunction includes a first fluid path, an inflatable penile prosthesis cylinder, an electric pump, and implant controller, and an implantable power supply. The inflatable penile prosthesis cylinder is in fluid communication with the first fluid path and is configured for implantation in a corpus cavernosum of a patient. The electric pump is in fluid communication with the first fluid path. The implant controller is electrically coupled to the pump and is configured to activate the pump to drive a flow of fluid through the first fluid path and into the cylinder. The implantable power supply provides electrical power to the pump.

A device for wrapping around a bodily organ and preventing overexpansion thereof. The device comprises inner and outer surfaces with a pliant material located therebetween. The inner surface defines a passage and accommodates and reinforces a bodily organ. The bodily organ, following surgical implantation, extends through the passage and is surrounded by the device. The inner surface, in an uncompressed/slightly compressed state, defines a normal state which supports the bodily organ and permits flow of bodily material therethrough. As the bodily organ expands, due to the bodily material flowing therethrough, the inner surface and the pliant material are compressed and, in turn, correspondingly exert a collapsing force, against the outer wall of the bodily organ, which limits and opposes the expansion of the bodily organ and forces the outer wall of the bodily organ back toward its normal state which still permits flow of bodily material through the bodily organ.

The present invention provides an artificial sphincter employing an easily controlled electro-mechanical pump system. The artificial sphincter includes an inflatable cuff, a control pump fluidly coupled to the inflatable cuff, and an electro-mechanical pump system. The inflatable cuff is adapted to surround a urethra or rectum of the patient to facilitate continence. An inflation element or balloon can be included to further control pressure to the cuff.

Method and system for treating a patient using an inflatable device. A removal device may be used to remove the inflatable device from the body. The removal device can have at least one manually-actuatable member and at least two opposing jaws at a distal end. At least one of the at least two jaws can be movable by actuation of the at least one manually-actuatable member. At least one of the at least two jaws can have a puncturing member.

A method is provided for maintaining the position of pelvic organs, such as components of the urinary tract. The method may involve anchoring the pelvic organs by inserting the implant via an anterior approach, avoiding complications and side effects that result when implants are inserted through the wall of the vagina.

An artificial urinary sphincter (AUS) system that includes a reservoir to hold a fluid, a cuff that includes a pre-shaped spiral tube to be wrapped around a urethra, and a control device to be fluidically coupled to the reservoir and the cuff. The control device regulates transfer of the fluid between the reservoir and the cuff. The cuff receives and dispatches the fluid to expand and contract the pre-shaped spiral tube and to coapt the urethra for continence and open the urethra for voiding.

An implantable medical device includes an electronic control system and an actuator. The actuator changes shape in response to a command or action of the electronic control system to treat an ailment of a person.

An implantable fluid operated device may include a fluid reservoir configured to hold fluid, an inflatable member, and a pump assembly configured to transfer fluid between the fluid reservoir and the inflatable member. The pump assembly may include one or more fluid pumps and one or more valves. An electronic control system may control operation of the pump assembly based on fluid pressure measurements and/or fluid flow measurements received from the one or more sensing devices. The electronic control system may include an internal component installed with the implanted device, and an external component that is operable by a user to provide user input, and to receive output from the implanted device.

An implantable fluid operated device may include a fluid reservoir configured to hold fluid, an inflatable member, and a pump assembly configured to transfer fluid between the fluid reservoir and the inflatable member. The pump assembly may include one or more fluid pumps and one or more valves. One or more sensing devices may be positioned within fluid passageways of the fluid operated device. The electronic control system may control operation of the pump assembly based on fluid pressure measurements and/or fluid flow measurements received from the one or more sensing devices. The pump assembly may include a piezoelectric pump. The one or more sensing devices may include one or more pressure transducers positioned in the fluid passageways, one or more strain gauges measuring deflection of piezoelectric elements, voltage input/output at one or more piezoelectric elements, and other types of sensing devices.
