In a method, system and device a member is provided around an aneurysm enabling treatment and monitoring of the aneurysm. In accordance with one embodiment the device is adapted to be adjusted postoperatively. Hereby the treatment can be efficiently carried out without having to perform surgery when adjusting the member.

An implantable drainage device is provided. The device is adapted to move body fluid from one part of the body of a patient to another part of the body.

A device and a method, by means of which energy can be supplied to a retinal implant (12) via infrared radiation, are provided. To this end, infrared light is coupled in from an infrared light source (14), for example into a spectacle lens (13), and coupled out toward an eye (10) by way of an output coupling device (17) in order to illuminate the retinal implant (12).

A gastroscopic method and instrument for treating obesity of a patient, using a device adapted to stretch a part of the stomach wall of said patient. The method comprises the steps of: inserting the device into the stomach through the esophagus, placing the device in contact with the stomach wall, and fixating the device to the stomach wall such that the device can stretch a part of the stomach wall.

Methods and devices are adapted for implanting into the eye. An incision is formed in the cornea of the eye and a shunt is inserted through the incision into the anterior chamber of the eye. The shunt includes a fluid passageway. The shunt is passed along a pathway from the anterior chamber through the scleral spur of the eye into the suprachoroidal space and positioned in a first position such that a first portion of the fluid passageway communicates with the anterior chamber and a second portion of the fluid passageway communicates with the suprachoroidal space to provide a fluid passageway between the suprachoroidal space and the anterior chamber.

The present invention relates to an implantable apparatus for obtaining urinary control and emptying of the urinary bladder, thereby preventing from or treating involuntary urinary retention. In general terms, the apparatus comprises an expandable member adapted to be implanted inside the urinary bladder of the patient for discharging urine, and a control device for controlling the volume of the expandable member. The control device is adapted to be connected to the expandable member through the wall of the urinary bladder.

A retinal prosthesis system according to an embodiment includes a converter, a retinal prosthesis, and a transmitter. The converter is placed in an eye, and transmits part of light incident on the eye therethrough while converting the energy of the other part of the light into electrical energy. The retinal prosthesis is placed in the eye and includes a photoelectric conversion element array configured to operate with the electrical energy received from the converter to detect the light having transmitted through the converter to generate an electrical signal. The transmitter is used to send the electrical signal generated by the retinal prosthesis to the visual cortex of the brain.

In a method and apparatus for supplying wireless energy to a medical device (100) implanted in a patient, wireless energy is transmitted from an external energy source (104) located outside a patient and is received by an internal energy receiver (102) located inside the patient, for directly or indirectly supplying received energy to the medical device. An energy balance is determined between the energy received by the internal energy receiver and the energy used for the medical device, and the transmission of wireless energy is then controlled based on the determined energy balance. The energy balance thus provides an accurate indication of the correct amount of energy needed, which is sufficient to operate the medical device properly, but without causing undue temperature rise.

Some embodiments of the disclosure may include a device for wirelessly powering an implant unit in a body of a subject from a location outside of the body of the subject, wherein the implant unit includes a secondary antenna for wirelessly receiving energy. The device may include a primary antenna configured to be located external to the body of the subject, a circuit electrically connected to the primary antenna, and at least one processor electrically connected to the primary antenna and the circuit. The at least one processor may determine a resonant frequency mismatch between a first resonant frequency associated with the primary antenna and a second resonant frequency associated with the secondary antenna associated with the implant unit; and apply an adjustment to at least one component of the circuit to cause a change in the first resonant frequency associated with the primary antenna and a reduction in the resonant frequency mismatch.

A subcutaneous arteriovenous graft system includes an arteriovenous graft having an arterial end, a venous end opposite to the arterial end and an internal volume between the arterial end and the venous end, and a valve device that can be arranged in an open state, in which fluid flow through the graft is possible and a closed state in which the fluid flow through the arteriovenous graft is blocked. The valve device is constructed to decrease, in the closed state of the valve device, the internal volume of the complete graft to substantially zero.
