Patent number: 8486086Abstract: An implant includes a tube for permitting fluid flow. A flow controlling rod may be inserted within the tube passage. One or more holes around the circumference of the tube may be selectively permanently or temporarily occluded to give desired flow characteristics. A delivery device for implanting the implant may include a central bore in which a retractable wire is located. The retractable wire penetrates a tube passage of the implant. After the implant is in position in the eye, the retention wire is retracted out of the implant. In a method for manufacturing an implant, two tubes of different diameters are utilized. The smaller tube fits inside the longitudinal bore of the larger tube. When the tubes are cut, the smaller tube forms the tube of the implant and the remaining portions of the larger tube form the retention projection and/or disk of the implant.Type: GrantFiled: November 7, 2011Date of Patent: July 16, 2013Assignee: Optonol, LtdInventors: Ira Yaron, Orit Yarden

Patent number: 8480693Abstract: A device and method for achieving hemostasis and leakage control in vascular structures and other body ducts or vessels in an emergency room or trauma situation. The device has at least one shunt that contains an obturator on an end of the shunt. The shunt is inserted into a damaged vessel or lumen for sealing the leak or hemorrhage. Two shunts that both contain obturators on one of their ends can be inserted into two different vessels or lumens when the vessel or lumen has been severed. The obturators allow for the improved ease of insertion into the vessel or lumen. The two shunts are then releasably attached to restore fluid communication through the vessel or lumen. The shunt is placed temporarily within the patient and then removed when definitive repair can be achieved by a qualified physician.Type: GrantFiled: February 19, 2008Date of Patent: July 9, 2013Assignee: Damage Control Surgical Technologies, Inc.Inventors: Robert F.
