A glaucoma treatment device applies electrolysis into an eye has a plurality of electrodes connected to a voltage source, and a controller coupled to a pressure sensor. The electrodes apply an electric field within an eye, and the controller regulates the delivery of current to the electrodes based on intraocular pressure measurements from the pressure sensor. The device has an enclosure for the pressure sensor, controller, and voltage source. The voltage source can recharge via an external source and the controller can accept adjustments remotely. The device also operates as a component in a method to convert aqueous humor into gas. The method utilizes electrolysis to reduce the volume of fluid in the anterior chamber of an eye. The method modulates electric current during usage of the invention. The method and device combine to reduce intraocular pressure within an eye thus lessening the progression of glaucoma.

The apparatus comprising a volume filling device adapted to be at least substantially invaginated by a stomach wall portion of the patient with the outer surface of the volume filling device resting against the stomach wall, such that the volume of the food cavity is reduced in size by a volume substantially exceeding the volume of the volume filling device. The apparatus further comprises at least one adjustable stretching device adapted to be at least substantially invaginated by a stomach wall portion of the patient with the outer surface of the stretching device resting against the stomach wall and adapted to stretch a portion of stomach wall, and a fluid connection device interconnecting the volume filling device and the stretching device.

An intraocular implant device for comprehensive intraocular vision advancement includes an intraocular implant body shaped for positioning inside a lens chamber of an eye. In some embodiments, the implant includes an optical adjustable base accommodating lens configured to provide both base adjustment and accommodation. In further embodiments, the implant includes a photoelectric sensor operable to receive incident light through the cornea and to convert the received light into electrical energy for use with one or more circuit components disposed on the body, and wherein the photoelectric sensor is also operable to convert the received light into image data. The ocular implant device may include a projector for projecting the image data onto the retina of a user. The ocular implant may additionally include an autofocusing digital camera, an autofocusing electromechanical lens array, and sensors for detecting glucose levels and/or intraocular eye pressure.

An intraocular micro-display system includes an intraocular micro-display (IOMD) implant and an auxiliary head unit for delivering power and image data to the IOMD implant. The IOMD implant includes an enclosure shaped for implantation into an eye, a micro-display to emit images towards a retina, an energy storage unit to power the micro-display, a charging antenna for wireless charging of the energy storage unit via a power signal incident upon the first charging antenna, and a data antenna to wirelessly receive the image data for driving the micro-display to emit the images. The charging antenna and the data antenna are implantable into the eye with the IOMD implant.

Apparatus consisting of a plurality of mechanically connected magnetic elements implanted around the lower esophagus sphincter with the purpose to restore its normal function in patients suffering from gastro-esophageal reflux disease (GERD), while avoiding dysphagia.

Devices, methods and systems for transmitting signals through a device located in a blood vessel of an animal, for stimulating and/or sensing activity of media proximal to the device, wherein the media includes tissue and/or fluid.

Systems and methods treat a heart valve using a magnetically adjustable annuloplasty ring attached to or near a cardiac valve annulus. A changing magnetic field may be used to selectively increase or decrease a circumference of, or otherwise modify the shape of, the implanted annuloplasty ring. The adjustable annuloplasty ring includes a tubular body member, one or more adjustable members, and an internal magnet within the tubular body member. The tubular body member and the one or more adjustable members form a ring shape. The internal magnet is configured to rotate in response to a rotating external magnetic field. The internal magnet is coupled to the one or more adjustable members to change a dimension of the ring shape as the internal magnet rotates. A system for treating a heart valve may include an external adjustment device having one or more external magnets to generate the rotating external magnetic field.

Apparatus (20) is provided, including a bifurcation stent (50) comprising one or more electrodes (32), the stent (50) configured to be placed in a primary passage (52) and a secondary passage (54) of a blood vessel (30), and a control unit (34), configured to drive the electrodes (32) to apply a signal to a wall (36) of the blood vessel (30), and to configure the signal to increase nitric oxide (NO) secretion by the wall (36). Other embodiments are also described.

An eye-implantable electrowetting lens can be operated to control an overall optical power of an eye in which the device is implanted. A lens chamber of the electrowetting lens contains first and second fluids that are immiscible with each other and have different refractive indexes. By applying a voltage to electrodes of the lens, the optical power of the lens can be controlled by affecting the geometry of the interface between the fluids. When the electrowetting lens is inserted into the eye, the lens chamber may contain only one of the first and second fluids. The other fluid can be added after insertion through a needle, a tube, or some other means. Having only one of the first and second fluids in the lens chamber during insertion of the lens can prevent fouling of internal surfaces due to folding or other manipulation of the lens during the insertion process.

A control assembly for implantation in a patient comprises a first unit adapted for subcutaneous implantation at a first side of a body tissue of said patient, a second unit adapted for implantation in a body cavity of said patient at a second side of said body tissue, wherein at least one of the first and the second unit is adapted to control an implanted powered medical device, and an interconnecting device adapted for mechanical interconnection of the first and second units to keep the assembly in place by the body tissue, the interconnecting device having a cross-sectional area which is smaller than the cross-sectional area of the first unit and the second unit in a plane parallel to the extension of the body tissue.
