  • Patent number: 11540916
    Abstract: An intraocular lens (IOL) for implantation within a capsular bag of a patient's eye comprises an optical structure and a haptic structure. The optical structure comprises a planar member, a plano convex member, and a fluid optical element defined between the planar member and the plano convex member. The fluid optical element has an optical power. The haptic structure couples the planar member and the plano convex member together at a peripheral portion of the optical structure. The haptic structure comprises a fluid reservoir in fluid communication with the fluid optical element and a peripheral structure for interfacing to the lens capsule. Shape changes of the lens capsule cause one or more of volume or shape changes to the fluid optical element in correspondence to deformations in the planar member to modify the optical power of the fluid optical element.

  • Patent number: 11529258
    Abstract: The present technology is directed to adjustable shunts for treating glaucoma. In particular, some embodiments provide shunts having a plurality of individually actuatable flow control elements that can control the flow of fluid through associated ports and/or flow lumens. For example, each individually actuatable flow control element can be actuated to block and/or unblock a corresponding port and/or flow lumen. Accordingly, the shunts described herein can be manipulated into a variety of configurations that provide different drainage rates based on whether the ports and/or flow lumens are blocked or unblocked, therefore providing a titratable glaucoma therapy for draining aqueous from the anterior chamber of the eye.

  • Publication number: 20220273423
    Abstract: An accommodating intraocular lens (AIOL) for implantation within a capsular bag of a patient's eye comprises first and second components coupled together to define an inner fluid chamber and an outer fluid reservoir. The inner region of the AIOL provides optical power with one or more of the shaped fluid within the inner fluid chamber or the shape of the first or second components. The fluid reservoir comprises a bellows region with fold(s) extending circumferentially around an optical axis of the eye. The bellows engages the lens capsule, and a compliant fold region between inner and outer bellows portions allows the profile of the AIOL to deflect when the eye accommodates for near vision. Fluid transfers between the inner fluid chamber and the outer fluid reservoir to provide optical power changes. A third lens component coupled to the first or second component provides additional optical power.

A movable barrier divides the chamber into a first section and a second section, and the barrier can be displaced by a differential pressure. A first powered inlet valve providing a fill path to the first section of the chamber, and a first powered drain valve providing a drain path from the first section of the chamber. A CSF inlet conduit connects a CSF space to the first powered inlet valve. A CSF outlet conduit connects the first powered outlet valve to a discharge location. A controller opens the first powered inlet valve and close the first powered drain valve to fill the first section to a volume defined by the barrier and chamber geometry and closes the first powered inlet valve and opens the first powered drain valve to discharge the filled volume from the first section through the outlet conduit.

  • Patent number: 11419719
    Abstract: A prosthetic valve coaptation assist device includes an anchor and a single valve assist leaflet. The anchor may be a supporting ring frame, brace or arc structure and will usually be radially self-expandable so that it can expand against surrounding natural or prosthetic tissue. The valve assist leaflet may be made of pericardium or other biological or artificial material and is shaped like the native target valve leaflet. The valve assist leaflet is typically sized larger than the target natural or prosthetic leaflet so that after implantation a significant overlap of the device body occurs.

  • Publication number: 20220202613
    Abstract: The present technology is directed to implantable medical devices for draining fluid from a first body region to a second body region. Some embodiments of the present technology provide adjustable devices that are selectively titratable to provide various levels of therapy. For example, the adjustable devices can have a drainage element with a lumen extending therethrough, a flow control element, and an actuation assembly. The actuation assembly can drive movement of the flow control element to change a dimension of and/or a flow resistance through the lumen, thereby increasing or decreasing the relative drainage rate of aqueous from an eye. In some embodiments, the actuation assembly and the flow control element together operate as a ratchet mechanism that can selectively move the flow control element between a plurality of positions and lock the device in a desired configuration until further actuation of the actuation assembly.
