Publication number: 20130131458Abstract: 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.Type: ApplicationFiled: May 8, 2012Publication date: May 23, 2013Applicant: MICROSURGICAL TECHNOLOGY, INC.Inventors: Boris E.

Patent number: 8439043Abstract: A retracting eye drape assembly is disclosed for use around a patient's eye to seclude and seal off the operative field during eye surgery. The drape assembly includes a retraction member connected to the drape and configured to engage the patient's eyelid, an extension member connected to the retraction member or to the drape and configured to substantially enclose the patient's eyelid, and a retraction flap configured to secure the patient's eyelid in a substantially retracted position. A method of applying an eye drape assembly is disclosed. After application of the drape to the patient's face, and while the patient's eyelid is closed, the patient's eyelid is engaged by a retraction member connected to the drape and retracted. While retracted, the patient's eyelid is substantially enclosed to seclude the eyelid and eyelashes from the operational area. The secluded eyelid and eyelashes are then secured in a retracted position.Type: GrantFiled: February 12, 2010Date of Patent: May 14, 2013Inventor: Andrew Peter Davis

Patent number: 8439833Abstract: A ring for dilating a pupil during an ophthalmic procedure includes a series of spaced supports for engaging an iris perimeter. The supports are plate elements which form an open pocket directed outwardly for engaging the iris. The sides of the ring form a primary plane, and the plates are located in respective planes above and below the primary plane. The outer periphery of the top and bottom plates forms a lip feature which is the opening to the pocket which retains the iris.Type: GrantFiled: October 18, 2011Date of Patent: May 14, 2013Assignee: Oasis Medical, Inc.Inventors: James Marlow Christensen, D.

Publication number: 20130072760Abstract: A speculum is provided herein which includes first and second arms, connected by a hinge, each having a channel formed thereon adapted to the shape of an eyelid. First and second elements are respectively located on the first and second arms configured to cooperatively retain the first and second arms in select rotational positions. A slot is defined in the second arm to partially separate first and second portions of the second arm with the first portion being displaceable away from the second portion. The second element is located on the first portion. Advantageously, with this arrangement, the first portion acts as a spring-loaded hinge which applies not only biasing force to the second element for retention, but also permits the second element to be separable from the first element. The subject invention provides a mechanical feature beyond the inherent memory of the material for operation of the speculum.Type: ApplicationFiled: September 21, 2011Publication date: March 21, 2013Applicant: BEAVER-VISITEC INTERNATIONAL (US), INC.Inventors: Frederick M.

Patent number: 8257256Abstract: A retractor for ophthalmic procedures and other uses is disclosed. The retractor is a U-shaped body formed by two arms and a live hinge, with a retracting means at the distal end of each arm. The retracting means includes a tongue blade for insertion under an eyelid, a deflector for retracting the eyelid, and two ball-tipped posts that extend away from the tongue blade and prevent eyelid or eyelashes from obscuring the window opened up by the retractor. The hinge is also an adjustable biasing spring that biases the distal ends of the arms to an open position. Anti-torque arches are provided on the outer wall of the body. A brace may be provided on the retractor, to fix the device to a desired position.Type: GrantFiled: October 22, 2010Date of Patent: September 4, 2012Inventor: Arthur M. M. Krolman
