  • Patent number: 11529228
    Abstract: Methods for treating presbyopia in a patient's eye involve inducing spherical aberration in a central area of the pupil. In embodiments, refractive properties of an eye are measured to obtain a baseline refractive correction. A lens for wearing on the eye is provided, or an optical device is implanted in the eye, or corneal tissue is removed to create spherical aberration or a distribution of spherical aberrations beyond the baseline refractive correction in the central area of the pupil. The central area of the pupil has a diameter of between 1.5 mm and 4.0 mm and has negligible spherical aberration without the treatment.

  • Patent number: 11504237
    Abstract: Cardiac valve repair devices with annuloplasty features and associated systems and methods are disclosed herein. A cardiac valve repair device configured in accordance with embodiments of the present technology can include, for example, an atrial fixation member configured to engage tissue within a left atrium proximate to a native mitral valve and a spring mechanism coupled to an inferior edge portion of the atrial fixation member. The spring mechanism has an extended state with a first length corresponding to a dimension of the atrial fixation member in a deployed state and a relaxed state with a shorter length corresponding to a desired dimension of the native valve annulus. When implanted, the spring mechanism contracts the atrial fixation member such that the native mitral annulus anchored to the atrial fixation member reduces in a cross-sectional dimension.

  • 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.
