Patent number: 12029686Abstract: Precise concentric, symmetric, and repeatable circular scoring (cutting) of Descemet's membrane is made possible by a handheld surgical ophthalmic device. The precision of the cut is provided by a stabilizing point on a stabilizing arm as well the anchoring insertion point at the limbus. Stabilization through the insertion point and the stabilizing arm provides a two-point fixation thereby establishing a cutting plane. The cutting plane allows for precise depth of cut whereas the rotating blade's consistent radius allows for circularity of the cut. The stabilization arm fixates on tissue, and is then removed when the procedure is completed. Consistent torque and contact pressure of the cutting blade is provided through rotational control via the depression of a button on a handle thereby removing the need to “free-hand” the desemetorhexis.Type: GrantFiled: March 15, 2022Date of Patent: July 9, 2024Assignees: The Board of Trustees of the Leland Stanford Junior University, The United States Government as represented by the Department of Veterans AffairsInventors: Michael Mbagwu, David Buickians, David Myung

Patent number: 12016970Abstract: A technique can consistently achieve thicknesses of ?50 ?m for corneal tissue for for Descemet stripping automated endothelial keratoplasty (DSAEK). Grafts with thicknesses of ?50 ?m are also known as nanothin DSAEK (NT-DSAEK) grafts. Evidence shows that using thinner DSAEK grafts, particularly NT-DSAEK grafts, can significantly improve visual outcomes. According to an example embodiment, a method for producing a corneal graft includes drying a donor cornea to cause a pre-cut thickness of the donor cornea to decrease. The method includes, concurrently with drying the donor cornea, determining pre-cut thickness measurements for the donor cornea. The method includes, in response to the precut thickness measurements indicating the pre-cut thickness of the donor cornea has decreased to a predetermined value, cutting the donor cornea to a post-cut thickness of ?100 ?m, or more particularly ?50 ?m, to produce a corneal graft.Type: GrantFiled: November 29, 2022Date of Patent: June 25, 2024Assignee: CorneaGen Inc.Inventors: Edward J.

Patent number: 9999541Abstract: The invention provides a positioning device for use in an examination, procedure or surgery of the eye. The positioning device includes an incurvate body with an upper peripheral edge having a first arc length, a lower peripheral edge having a second arc length, and a curved lateral portion therebetween. The lower peripheral edge has an arc length that is longer than the first arc length, as well as one to eight indentations of a size effective to receive a surgical instrument. The incurvate body of the positioning device of the invention is configured to engage at least a portion of the eye posterior to the corneal limbus and beneath which the pars plana is located. The positioning device can also include a handle pivotably attached to the incurvate body. The positioning device can be used to stabilize the eye as well as assist in accurate positioning of instruments during eye examination, procedure or surgery involving the anterior or posterior segment of the eye.Type: GrantFiled: August 4, 2016Date of Patent: June 19, 2018Inventor: Samir Sayegh

Patent number: 9833359Abstract: A tympanostomy tube delivery device comprises a drive assembly and a force limiting shaft assembly. The shaft assembly comprises a cannula and a piercer operable to translate relative to the cannula so as to pierce the tympanic membrane of a patient. The piercer is mechanically coupled with the drive assembly such that actuation of the drive assembly causes translation of the piercer relative to the cannula. The piercer is mechanically coupled with the drive assembly by a clutch. The clutch is resiliently biased to couple the piercer with the drive assembly. The clutch is configured to uncouple the piercer from the drive assembly in response to a threshold force being imposed upon the piercer so as to inhibit translation of piercer relative to the cannula.Type: GrantFiled: August 12, 2014Date of Patent: December 5, 2017Assignee: TUSKER MEDICAL, INC.Inventor: Mathew D. Clopp

Patent number: 9808279Abstract: A medical knife includes a blade plate and a blade portion formed at the distal end of the blade plate. Cutting edges extend from the distal end to the proximal end of the blade portion. Two blade surfaces in the width direction of a back-face portion of the blade portion are formed to gradually increase a distance between opposite side and cutting edge from one of the distal end and the proximal end to the other. The two blade surfaces in the width direction of a front-face portion of the blade portion are formed such that the distance between the opposite side and the cutting edge becomes equal in a zone corresponding to a distal end of the cutting edge and a zone corresponding to a proximal end of the cutting edge, over the entire cutting edge from the distal end to the proximal end of the cutting edge.Type: GrantFiled: April 27, 2012Date of Patent: November 7, 2017Assignee: KAI R&D CENTER CO., LTD.Inventors: Makoto Mori, Hidetoshi Amemoto, Kazuyuki Hasebe

Patent number: 9787526Abstract: Method and apparatus for providing Mobile internet protocol (IP) service through a network address translation gateway. In one example, a gateway between a local area network (LAN) and a wide area network (WAN) is provided. A foreign agent (FA) module is configured to advertise a care-of address (CoA) on the LAN and process registration and mobile IP communication traffic on the LAN and the WAN side of the gateway. A control module is configured to identify the registration and the mobile IP communication traffic on the LAN and the WAN. The control module sends mobile IP traffic to the FA and other traffic to a network address translation (NAT) module. In this manner, network address translation of mobile IP traffic is advantageously omitted. This allows the IP-in-IP tunnels used by mobile IP to pass through the gateway.Type: GrantFiled: June 17, 2014Date of Patent: October 10, 2017Assignee: Google Technology Holdings LLCInventor: Jay Strater
