  • Patent number: 11903575
    Abstract: Anchor delivery systems include anchors having a generally cylindrical body with a rail on top for positioning within a delivery device slot. The rail incorporates a side-bulge as a retaining feature which axially extends along a majority of the length of the rail. The bulge interferes with a corresponding hourglass cutout in the delivery device slot to prevent the anchor from stripping out of the delivery device when the delivery device is retracted through tissue. The anchors are symmetrical along a length and width to facilitate loading within the delivery device. The distal portion of the delivery device includes a series of distally-extending barbs that intentionally change the penetration force required to push the device tip through tissue.

  • Patent number: 11813198
    Abstract: The first step for removal of cataracts generally is a capsulotomy—the removal of the anterior capsule of the eye lens. The circular capsulotomy incision tool provides a device that produces sharper cuts, with precise measurements, in an economical, reliable form without the need for complicated or expensive equipment, or extensive surgeon training or skill. The tool uses a resilient ring with a sharp cutting edge. The ring is collapsed, put in place through a corneal incision, and the original circular shape is allowed to return. The device uses a pulley mechanism to rotate the ring, enabling the cutting edge to reliably create a precisely edged capsulotomy.
