  • Patent number: 11793503
    Abstract: A length or strand of resilient material is formed into a continuous ring having multiple tissue-engaging portions for engaging and spreading eyeball tissue segments apart. The strand is formed with elongated straight sides joined by corner portions which are enlarged in directions transverse to the length dimension of each adjacent side. The corner portions constitute the tissue-engaging portions and have top and bottom sections and a connecting section that forms a gap for receiving the tissue. Each side of the ring extends from a bottom section of one corner to a top section of an adjacent corner. When the ring is deployed, the tissue is captured in the gaps at the corners of the ring and also is engaged along each side as that side transitions from a position situated below the tissue to a position situated above the issue.

  • Publication number: 20230157874
    Abstract: A device and method for cutting or ablating tissue in a human or veterinary patient includes an elongate probe having a distal end, a tissue cutting or ablating apparatus located adjacent within the distal end, and a tissue protector extending from the distal end. The protector generally has a first side and a second side and the tissue cutting or ablating apparatus is located adjacent to the first side thereof. The distal end is structured to be advanceable into tissue or otherwise placed and positioned within the patient's body such that tissue adjacent to the first side of the protector is cut away or ablated by the tissue cutting or ablation apparatus while tissue that is adjacent to the second side of the protector is not substantially damaged by the tissue cutting or ablating apparatus.

  • Patent number: 11602456
    Abstract: A method of implanting a continuous iris-expanding ring in an eye involves ejecting the continuous iris-expanding ring from a distal end of a cannula toward an iris of the eye, securing a distal portion of the continuous iris-expanding ring device ring to the iris of the eye, and securing a proximal portion of the continuous iris-expanding ring to the iris of the eye. The continuous iris-expanding ring is in a collapsed configuration in the cannula prior to being ejected and in an expanded configuration when the proximal portion and the distal portion of the continuous iris-expanding ring are secured to the iris of the eye and extend across the pupil.

  • Publication number: 20230014011
    Abstract: Provided are embodiments of systems, devices and methods to aid in or perform the capsulotomy procedure via access into an eye through a small incision. Embodiments of the present disclosure may employ the unique characteristics of shape-memory materials to enable device access into the eye through the requisite small incision size, and via simple mechanical means either to create a template for surgeons to follow in order to create an appropriately-sized capsulotomy, or to create such a capsulotomy via cutting, tearing, or abrading the lens capsule.

  • Patent number: 11097045
    Abstract: An ophthalmic irrigator-aspirator has a handpiece with aspiration and irrigation openings through its distal end. A tip component connects to the handpiece and has an aspiration cannula. A flexible sleeve has an annular hub for watertight connection to the handpiece or a base portion of the tip. The sleeve has an intermediate portion that forms a channel for an irrigation fluid along the exterior of the cannula to an irrigation port in the sleeve. The distal end portion of the sleeve is sized for a watertight connection over the distal portion of the cannula. Such distal end portion of the sleeve has an aspiration port in communication with the cannula aspiration port. The sleeve proximate, intermediate, and distal portions are integral with each other and are formed of a resilient material that allows the sleeve to be tightly fitted on the handpiece or tip base portion and the cannula.
