Systems, devices, kits, and methods are described for securing a bioprosthetic heart valve within an anatomical feature of a patient. Kits can comprise a bioprosthetic heart valve, a curable composition, and an applicator configured to deliver the curable composition to a target area. The bioprosthetic heart valve can comprise a support structure and one or more valve leaflets coupled thereto. The support structure can comprise a sewing portion peripheral of the bioprosthetic heart valve. The support structure and the valve leaflets can define a central flow orifice. The curable composition can comprise a pre-polymer composition and an initiator. Methods can comprise positioning the bioprosthetic heart valve within the anatomical feature of a patient, applying the curable composition to one or both of the bioprosthetic heart valve and the anatomical feature, and curing the curable composition for a cure time. The applying can be performed before or after the positioning.

Disclosed are devices, systems, and methods for restoring vision to a subject. In one embodiment, the vision restoration device comprises a projector configured to project one or more digital images onto a central retina of the subject and one or more lenses coupled to the projector and configured to focus the one or more digital images. The vision restoration device can also comprise an extraocular component configured to be implanted within the subject and comprising one or more processors programmed to execute instructions stored in a memory to wirelessly receive the one or more digital images from an extracorporeal device. The intraocular projection component can be connected or coupled to the extraocular component by a trans-scleral communication wire configured to cross the sclera of the eye. The trans-scleral communication wire is configured to transmit digital data between the extraocular component and the intraocular projection component.

A shunt valve for removing biofluid from an eye of a user, the valve including a tubular body defining an inlet and a plurality of outlets formed through a wall of the tubular body; a plunger accommodated within the tubular body and fluidically coupled to the inlet; wherein the plunger is movable relative to the plurality of outlets; and an energized material coupled to the plunger and the tubular body; wherein the energized material is compressible to expose a portion of the plurality of outlets dependent on the pressure applied to the energized material.

An intraocular micro-display (IOMD) system includes an auxiliary head unit. The auxiliary head unit includes a frame for mounting to a head of a user, a scene camera module mounted in or on the frame in a forward-facing orientation, a gaze tracking module disposed in or on the frame and configured to monitor an eye of the user, and an auxiliary controller. The auxiliary controller includes for: acquiring a scene image with the scene camera module, determining a gazing direction of the eye based upon gaze direction data from the gaze tracking module, identifying a sub-portion of the scene image based upon the gazing direction, and wirelessly relaying the sub-portion of the scene image to an IOMD implant within the eye for displaying to a retina of the eye.

This application relates to a breast implant and an apparatus for sensing an abnormality of the breast implant. In one aspect, the breast implant includes a shell including an injection hole and forming an outer cover of the breast implant and a filler of a gel state injected into the shell through the injection hole. The breast implant may also include a first patch configured to seal the injection hole, the first patch including a first sensor module. The breast implant may further include a second patch configured to be attached on at least one of a second position facing the first position and a third position to which a pressure due to a gravity is applied when the breast implant is inserted in a breast and a body is kept upright without an external pressure applied, the second patch including a second sensor module.

Devices, systems, and methods for passively regulating or controlling Intraocular Pressure (TOP) are provided. According to some aspects, a device is configured to be implanted or attached to a patient's eye to provide regulated drainage of aqueous humor (AH) out of the eye into the tear film of the eye, which is an exterior surface of the eye. The device may include a housing comprising an inlet and an outlet, and a pressure relief valve coupled to the housing. The pressure relief valve is configured to open to allow passage of the aqueous humor from an ingress of the pressure relief valve to an egress of the pressure relief valve in response to a pressure of the aqueous humor on the ingress of the pressure relief valve exceeding a threshold. The device further includes a filter configured to allow passage of fluid from the egress of the pressure relief valve through the outlet of the housing along a fluid path extending from the inlet of the housing to the outlet.

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.

An apparatus for treating obesity of a patient having a stomach with a food cavity. 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 artificial valve for implantation in a mammal body, in or adjacent to a mammal blood vessel, the artificial valve comprising a casing and a closing mechanism, with at least part of said closing mechanism being a first moving part adapted to make movements relative to said casing. The movements are movements to assume a fully open and a fully closed position for opening and closing, respectively, the blood flow through said blood vessel, as well as at least one position in between said fully open and fully closed positions. The first moving part is adapted to receive energy for at least one of its movements at least in part from an energy device which is also comprised in the artificial valve and arranged to be placed external to said blood vessel.

A blood clot removal device for removing blood clots from the vascular system of a patient is implantable in the patient's body. The blood clot removal device comprises a blood flow passageway to be connected to the patient's vascular system to allow circulation of the patient's blood through the blood flow passageway, a filter provided in the blood flow passageway for collecting blood clots occurring in the blood flowing through the blood flow passageway, and a cleaning device for moving blood clots collected by the filter out of the blood flow passageway. By means of such blood clot removal device, the risk of blood clots reaching sensitive areas of the patient's body, such as the brain, is reduced.
