Patent number: 6660019Abstract: A stent and a method for fabricating the stent are disclosed. The stent has an originally flat pattern and connection points where the sides of the flat pattern are joined. The method includes the steps of a) cutting a stent pattern into a flat piece of metal thereby to produce a metal pattern, b) deforming the metal pattern so as to cause two opposing sides to meet, and c) joining the two opposing sides at least at one point. Substantially no portion of the stent projects into the lumen of the stent when the stent is expanded against the internal wall of a blood vessel.Type: GrantFiled: July 24, 2000Date of Patent: December 9, 2003Assignee: Medinol Ltd.Inventors: Jacob Richter, Ira Yaron

Publication number: 20030208163Abstract: An implant having a tube for permitting fluid flow has an outer flange at the outlet end and a retention projection near the inlet end. A delivery device for implanting the implant has a central bore for accommodating the implant during the implantation procedure. When the implant is loaded in the delivery device, the retention projection of the implant protrudes beyond the outside surface of the delivery device. After the delivery device and implant have penetrated the tissue through which drainage is desired, and the retention projection has fully penetrated through the tissue, the delivery device is withdrawn. The retention projection acts as a hook engaging the inside surface of the tissue, causing the implant to stay implanted in the tissue. An implant may also be provided with a mechanism for temporary occlusion, in whole or in part, of the flow passage.Type: ApplicationFiled: August 6, 2001Publication date: November 6, 2003Applicant: Optonol Ltd.Inventors: Ira Yaron, Orit Yarden

Publication number: 20030093084Abstract: The disclosed delivery devices for flow regulating implants comprise a handle and a tube (such as a hollow needle or cannula), with a retractable wire extending through the tube. Prior to deployment, the wire extends a short distance out of the distal end of the tube. The flow regulating implant is mounted on the wire at the distal end of the tube; for example, the implant may have a central bore into which the wire extends. The implant may be held on the wire by friction, by a hook, or by other suitable means. The delivery device includes a trigger that acts on the retractable wire. Actuating the trigger retracts the wire into the tube, thereby releasing the implant.Type: ApplicationFiled: November 13, 2001Publication date: May 15, 2003Applicant: OPTONOL LTD.Inventors: Oded Nissan, Sagi Ben-Rimon, Ira Yaron

Publication number: 20030079329Abstract: 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.Type: ApplicationFiled: December 9, 2002Publication date: May 1, 2003Inventors: Ira Yaron, Orit Yarden

Patent number: 6510600Abstract: 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 when the implant is attached to the delivery device. A hook on the delivery device prevents the implant from moving down the wire. After the implant is in position in the eye, the retention wire is retracted out of the implant. With the retention wire retracted, the implant is then free to slide away from the hook, allowing the delivery device to be withdrawn, leaving the implant in place. 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.Type: GrantFiled: December 4, 2000Date of Patent: January 28, 2003Assignee: Optonol, Ltd.Inventors: Ira Yaron, Orit Yarden

Publication number: 20020177856Abstract: An ophthalmic implant for treatment of glaucoma, a delivery device for implanting such an implant, and a method of implanting such an implant. The implant includes a tube having an inlet end, an outlet end, and a tube passage therebetween, and a disk connected to the tube at the outlet end of the tube. The tube passage has a cross-sectional area sufficiently small to inhibit the flow of aqueous humor through the tube passage. The implant provides a bleb of aqueous humor under the conjunctiva so that the bleb and the elasticity of the conjunctiva assist in regulating the flow of aqueous humor through the tube as a function of the IOP. The tube at its inlet end has a beveled surface facing away from the iris and one or more circumferential holes. One or more retention projections are provided for anchoring and may be extended outwardly when the implant is implanted in the eyeball. The disk has an outer rim and one or more inner uprights.Type: ApplicationFiled: July 9, 2002Publication date: November 28, 2002Inventors: Jacob Richter, Gregory Pinchasik, Ira Yaron

Patent number: 6156052Abstract: A stent and a method for fabricating the stent are disclosed. The stent has an originally flat pattern and connection points where the sides of the flat pattern are joined. The method includes the steps of a) cutting a stent pattern into a flat piece of metal thereby to produce a metal pattern, b) deforming the metal pattern so as to cause two opposing sides to meet, and c) joining the two opposing sides at least at one point. Substantially no portion of the stent projects into the lumen of the stent when the stent is expanded against the internal wall of a blood vessel.Type: GrantFiled: November 13, 1998Date of Patent: December 5, 2000Assignee: Medinol Ltd.Inventors: Jacob Richter, Ira Yaron
