Patent number: 11944573Abstract: Systems and methods for delivering multiple ocular implants to reduce intraocular pressure are disclosed. The ocular implants can be implanted at multiple sites within a single human eye without requiring removal of the delivery apparatus from the eye. A system for delivering multiple ocular implants can include at least two implants preloaded within a delivery device and configured to be implanted within the eye, a metering device configured to transfer energy to the implants for delivery at selected locations within the eye, wherein the metering device is configured to meter a variable amount of energy for each implant delivery event in the eye. The system can further include an injector mechanism configured to serially engage and drive each of the implants.Type: GrantFiled: December 3, 2021Date of Patent: April 2, 2024Assignee: Glaukos CorporationInventors: David Steven Haffner, Henrick K. Gille, Charles Raymond Kalina, Jr., John Joseph Cogger

Publication number: 20240090762Abstract: Gonioscope devices are disclosed herein that are configured to enable a medical professional to view structure inside the eye that is ordinarily hidden from normal view. The gonioscope can be an integrally molded single piece that includes both a handle and a gonioscopic optical element. The proximal surface can have a viewing area and a light diffusing area. A recess can provide access to a wound site on the eye while the gonioscope is used for viewing. The handle can be configured to encourage proper alignment of the gonioscope with the eye. The gonioscope can provide an optical fixation point for the subject to focus on to facilitate proper alignment of the eye. The gonioscope can have one or more retention elements configured to engage the tissue of the eye around the contact surface to stabilize the gonioscope. The gonioscope can couple to a lid speculum.Type: ApplicationFiled: July 20, 2023Publication date: March 21, 2024Inventors: Charles Raymond Kalina, JR., Huong Khac Huynh, Douglas Daniel Crimaldi, Todd N.

Patent number: 11826104Abstract: A gonioscopic attachment can attach to a gonioscope and can include atraumatic retention elements that are configured to engage an eye to retain the gonioscope relative to the eye. The gonioscopic attachment can be configured to position the gonioscope so that at least a portion of the concave distal surface of the gonioscopic optical element is spaced apart from the eye, and/or so that the curvature of the distal surface is angularly offset from the curvature of the eye. The gonioscope can include a fixation point configured to be visible to the subject when the gonioscope is positioned on the eye. In some embodiments, the retention elements can be incorporated directly into the gonioscope. A coupling mechanism can couple the gonioscope to a lid speculum. The gonioscope can include a light pipe, which can be configured to directly light into the eye.Type: GrantFiled: May 27, 2021Date of Patent: November 28, 2023Assignee: Glaukos CorporationInventors: Charles Raymond Kalina, Jr., Thomas W. Burns, Chris Calcaterra, Edward Collins, Timothy McCauley, David S. Haffner, Steven M. Henderson

Publication number: 20230210694Abstract: The invention relates generally to medical devices and methods for reducing the intraocular pressure in an animal eye and, more particularly, to stent type devices for permitting aqueous outflow from the eye's anterior chamber and associated methods thereof for the treatment of glaucoma. Some aspects provide a self-trephining glaucoma stent and methods thereof which advantageously allow for a “one-step” procedure in which the incision and placement of the stent are accomplished by a single device and operation. This desirably allows for a faster, safer, and less expensive surgical procedure.Type: ApplicationFiled: January 11, 2023Publication date: July 6, 2023Inventors: Douglas Daniel Crimaldi, Charles Raymond Kalina, Jr.

Publication number: 20220330979Abstract: Systems and methods for delivering multiple ocular implants to reduce intraocular pressure are disclosed. The ocular implants can be implanted at multiple sites within a single human eye without requiring removal of the delivery apparatus from the eye. A system for delivering multiple ocular implants can include a plurality of implants, an external housing, and an introducer assembly. The external housing can provide access to an implant singulation actuator and an implant delivery actuator. The introducer assembly can comprise an auto-retracting introducer portion. The delivery apparatus can include an infinite activation mechanism/portion and/or a manual singulation mechanism/portion.Type: ApplicationFiled: June 30, 2022Publication date: October 20, 2022Inventors: Charles Raymond Kalina, JR., Todd N. Fjield, Douglas Daniel Crimaldi, Emma Claire Benjaminson, Tyler Joseph Brown, Richard William Martin

Publication number: 20210369447Abstract: Some embodiments disclosed herein relate to devices and methods for controlling placement of intraocular implants within a patient's eye including but not limited to placement within or near the collector ducts of Schlemm's canal located behind the trabecular meshwork. In some embodiments, a handheld peristaltic rotor device having a compression element can be positioned on a corneal surface of the eye and rotated to create a peristaltic movement of blood in one or more episcleral veins to generate blood reflux within Schlemm's canal such that one or more collector ducts, or channels, of Schlemm's canal can be located. In some embodiments, an implant can be implanted near the identified location of the one or more collector ducts, or channels.Type: ApplicationFiled: August 12, 2021Publication date: December 2, 2021Inventor: Charles Raymond Kalina, JR.
