  • Patent number: 11554017
    Abstract: Dislodgment of a constricting cord from an annulus can be prevented by delivering the distal loop portion of the constricting cord to the annulus using a percutaneous delivery tool, and launching anchors into the annulus so as to affix the distal loop portion of the constricting cord to the annulus. The percutaneous delivery tool is withdrawn in a proximal direction after the anchors have been launched. A pushing member is pressed in a distal direction so that the pushing member holds a portion of the constricting cord against the annulus with enough pressure to prevent dislodgment of any of the anchors during the withdrawal of the percutaneous delivery tool.

  • Patent number: 11406388
    Abstract: The present disclosure relates to repair devices, repair systems, and methods for repair of regurgitant tricuspid valves. A repair method includes positioning a repair device at a tricuspid valve. The repair device includes a pair of proximal arms and a pair of corresponding opposing distal arms, with each proximal arm and corresponding opposite distal arm forming an arm pair. The arms are actuated so that leaflet tissue is grasped between the proximal and distal arms, with a first leaflet being grasped by a first arm pair and a second leaflet being grasped by a second arm pair. A suture line is anchored at the second leaflet. Then, the repair device is pivoted to grasp and suture a third tricuspid leaflet to tie the second and third leaflets together. The clip remains deployed to tie the first and third leaflets together.

  • Patent number: 11395763
    Abstract: A unique vitrectomy probe with an interfacing component for attenuating vibrations during a vitrectomy procedure. The component may be of elastomeric construction tailored to attenuating the vibrations. Additionally, the component may strategically reside at an interface between the housing that accommodates moving parts of the probe and an ergonomic shell meant for resting at purlicue a surgeon's hand. In this way, vibrations are largely attenuated before reaching the shell and distracting the surgeon. Additionally, the shell, housing and interface are architecturally constructed for user-friendly shell removal for surgeons wishing to perform vitrectomy procedures in absence of the shell.
