20160067088 | INTRAOCULAR IRRIGATOR-ASPIRATOR TIP COMPONENT - 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. | 03-10-2016 |
20150088056 | INTRAOCULAR IRRIGATOR-ASPIRATOR TIP COMPONENT - An ophthalmic irrigator-aspirator has a handpiece with aspiration and irrigation openings through its distal end; and a narrow aspiration tip projecting distally. A flexible sleeve has an annular hub for watertight connection to the handpiece. The sleeve has an intermediate portion that forms a channel for an irrigation fluid along the exterior of the tip 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 tip. Such distal end portion of the sleeve has an aspiration port in communication with the tip 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 and tip. | 03-26-2015 |
20140107565 | INTRAOCULAR IRRIGATOR-ASPIRATOR TIP COMPONENT - An ophthalmic irrigator-aspirator has a handpiece with aspiration and irrigation openings through its distal end; and a narrow aspiration tip projecting distally. A flexible sleeve has an annular hub for watertight connection to the handpiece. The sleeve surrounds the full extent of the tip. An intermediate portion of the sleeve forms a channel for an irrigation fluid along the exterior of the tip to a port in the sleeve. The distal end of the sleeve is sized for a watertight connection over the distal portion of the tip. Such distal end of the sleeve has an aspiration port in communication with the tip 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 manually stretched onto the handpiece and tip. | 04-17-2014 |
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 |
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 |
20120290086 | INTRAOCULAR CAPSULAR TENSION RINGS - Arcuate arms each approximately semi-circular extend generally oppositely from a central fixation element. Together the arms and integral fixation element form a capsular tension ring to apply outward pressure along the equator of an ocular lens capsule during surgery. The ring can be loaded into an insertion tube by pulling on the central fixation element such that the arms are drawn into the tube together. Similarly, the arms are expelled together from the tube during insertion into the capsule so as to equalize the force applied to the capsule during insertion of the ring. | 11-15-2012 |
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 |
