20080243139 | Method for assembling a ring used in a small pupil phaco procedure - A ring that can maintain a pupil in an extended position during an ophthalmic procedure. The ring has a plurality of loops that capture iris tissue. The ring is configured to extend the pupil when iris tissue is inserted into each loop. An ophthalmic procedure such as phacoemulsification can then be performed on the patient. The ring has a first end and a second end that each have an indent. The ring includes an adhesive that extends into the indents and attaches the first end to the second end. | 10-02-2008 |
20120289786 | EXTENSION RING FOR EYEBALL TISSUE - A strand of resilient material has multiple tissue-engaging portions for engaging and spreading eyeball tissue segments apart. The strand is formed as a continuous ring with straight sides joined by corner portions. The corner portions constitute the tissue-engaging portions and have top and bottom sections and a connecting arc of the strand to form a gap receiving for receiving the tissue. | 11-15-2012 |
20130131458 | EXPANSION RING FOR EYEBALL TISSUE - 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. | 05-23-2013 |
20130197533 | OCULAR LENS CAPSULE RETAINER - A thin resilient strand, such as medical suture material, extends from a stiffer shank. The strand can form a resilient hook and/or it can have an arcuate free end to engage tissue such as the interior of a capsular bag at approximately its equator during ophthalmic surgery. | 08-01-2013 |
