A device for controlling urinary flow comprises a fluid inlet and a fluid outlet. The device comprises a valve movable between an open position in which fluid can flow from the fluid inlet to the fluid outlet and a closed position in which fluid flow is blocked between the fluid inlet and the fluid outlet, and an actuator operable to move the valve between the open position and the closed position. The actuator is positioned on a first side of the fluid inletand the fluid outlet is positioned on a second, opposite side of the fluid inlet.

A prosthetic valve comprises a frame assembly having a first opening at an inflow portion of the frame assembly and a second opening at an outflow portion of the frame assembly, a first sensor device situated at the inflow portion of the frame, and a second sensor device situated at the outflow portion of the frame. Each of the first sensor device and the second sensor device is configured to sense a physical parameter and provide a sensor signal. The prosthetic valve further comprises a transmitter assembly configured to receive the sensor signals from the first sensor device and the second sensor device and wirelessly transmit a transmission signal based at least in part on the sensor signals.

A stent device including a stent coated with a photosensitizer, the stent including a pair of electrodes; and a circuit fixed to the stent, the circuit including a light emitting diode, a power receiving means for wirelessly receiving power from the outside, and converting the power to electric power; a second communicating means for receiving a control command from the outside; and a second control means for applying, based on the control command, the electric power to the electrodes causing an electric current to flow through the stent between the electrodes, the flow causing heating of the stent, and for controlling a temperature of the stent to provide hyperthermia therapy to a tumor, the second control means further for applying, based on the control command, the electric power to the light emitting diode to emit a predetermined wavelength of light to the photosensitizer to provide photodynamic therapy to the tumor.

A method of implanting a device in a heart includes inserting an implant into a blood vessel with a delivery apparatus. The implant includes a stent member and an adjustment member. The stent member is circumferentially expandable and contractible. The adjustment member is coupled to the stent member. The delivery apparatus includes a rotatable shaft and a locking mechanism coupled to an end portion of the shaft. The shaft of the delivery apparatus is releasably coupled to the adjustment member of the implant by the locking mechanism of the delivery apparatus. The method further includes positioning the implant at an implantation location within a heart by manipulating the delivery apparatus, and rotating the shaft of the delivery apparatus relative to the stent member of the implant to actuate the adjustment member of the implant. Actuating the adjustment member results in circumferential expansion or contraction of the stent member.

A medical treatment system for determining administration of medications to a patient is disclosed. The system uses a plurality of sensors to perform a first set of physiologic measurements in a right side of the heart and a second set of physiologic measurements in a left side of the heart. The system also includes a receiver configured to receive measurement data regarding the first and second sets of physiologic measurements and output to a display device the received measurement data.

The present disclosure provides a system for delivery of therapeutic energy. The system includes an energy unit configured to convert the acoustic energy signals transmitted to therapeutic ultrasound directed to fragment tumors and carcinogenic tissue in the body. The system also includes an energy unit configured to convert the acoustic energy signal transmitted from the energy unit to ultrasonic energy to image and monitor the treatment site with ultrasound. The system also includes a control unit including a computer for data storage and display.

A method of initiating operation of an external unit for a medical system further comprising an internal unit implanted into a body of a patient; a transformer core arranged under the skin of the patient; and internal cabling connecting the internal unit and the transformer core, the internal cabling comprising an internal winding around the transformer core, wherein the external unit comprises external cabling including an external winding around the transformer core to allow supply of power from the external unit to the internal unit via the transformer core, the method comprising the steps of: evaluating, by the external unit, a signal indicative of a magnetic flux in the transformer core; when the signal indicates that the magnetic flux in the transformer core is below a predefined threshold flux, providing power to the internal unit by the external unit via the transformer core.

Lens support structure for supporting an intraocular lens (IOL) is provided, the lens support structure being configured and operable to be securely implanted in a lens capsule of a human eye and hold the IOL in one of a plurality of positions, the support structure comprising a repositioning assembly configured and operable to be activated remotely by a remote energy source and controllably displace the IOL in at least one of directions along and around an optical axis of the IOL, thereby enabling moving the IOL between the plurality of positions. Lens control system is also provided, the control system comprising the lens support structure and a source energy for activating parts thereof. Intraocular lens system is also provided, the system comprising the lens support structure and a lens integrated therein.

An artificial sphincter to be implanted in a urethra, for treating patients suffering from urinary incontinence, includes a container configured to be connected to a wall of a urethra, inside or outside it, a valve unit housed within the container and configured to move from a release configuration to a block configuration and vice-versa. An actuation magnet is movably (rotatably or slidably) arranged between a first and a second position in the container, and is connected to the valve unit such that a predetermined (rotation or translation) movement of the actuation magnet from a first towards a second position, or from the second towards the first position, under the effect of an external manoeuvre magnet, brings the valve unit from the release configuration to the block configuration, where the valve is stably maintained, and from the block configuration to the release configuration, where the valve is stably maintained.

The invention relates surgical abdominal methods of treating obesity in a patient by implanting a volume filling device that, when implanted in a patient, reduces the food cavity in size by a volume substantially exceeding the volume of the volume filling device. Also disclosed is a laparoscopic instrument for providing a volume filling device to be invaginated in the stomach wall of a human patient to treat obesity.
