Publication number: 20150223981Abstract: A method is provided for treatment of cataract in combination with a glaucoma procedure while maintaining the intraocular pressure by permitting aqueous to flow out of an anterior chamber of the eye through a surgically stented pathway. A trabecular stent is adapted for implantation within the trabecular meshwork of an eye such that intraocular liquid flows controllably from the anterior chamber of the eye to Schlemm's canal, bypassing the trabecular meshwork. Depending upon the specific treatment contemplated, pharmaceuticals may be utilized in conjunction with the trabecular stent enabling post-cataract healing processes.Type: ApplicationFiled: November 10, 2014Publication date: August 13, 2015Inventors: Gregory T. Smedley, David Haffner, Barbara Niksch, Hosheng Tu, Thomas W. Burns

Patent number: 8348877Abstract: Implants and methods for treating ocular disorders are provided. One method involves introducing an implant into an anterior chamber of an eye such that at least a distal end of the implant is temporarily in the anterior chamber. The implant is implanted into eye tissue adjacent the anterior chamber. A therapeutic agent is eluted from the implant into at least one of the anterior chamber, a physiologic outflow pathway of the eye, and a space adjacent a choroid of the eye. The therapeutic agent can be an antiproliferative agent, an anti-inflammatory drug, or a compound for treating glaucoma or ocular hypertension. The therapeutic agent can be contained within the implant or coated on the implant.Type: GrantFiled: May 3, 2010Date of Patent: January 8, 2013Assignee: Dose Medical CorporationInventors: Hosheng Tu, Barbara Niksch, David Haffner, Gregory Smedley, Olav B Bergheim, Morteza Gharib

Patent number: 7708711Abstract: Devices and methods are provided for the treatment of ocular disorders. An ocular implant has a body comprising material that includes a therapeutic drug. The body has an inlet portion and an outlet portion. The inlet portion is configured to reside in an anterior chamber of an eye when the outlet portion is disposed in a physiological outflow pathway of the eye. The outlet portion has an outflow opening such that the body drains fluid from the anterior chamber to the physiological outflow pathway. One method of treating an ocular disorder involves introducing an implant comprising a therapeutic drug into the eye such that the implant drains aqueous humor into a physiological outflow pathway and the therapeutic drug reaches eye tissue.Type: GrantFiled: November 12, 2003Date of Patent: May 4, 2010Assignee: Glaukos CorporationInventors: Hosheng Tu, Barbara Niksch, David Haffner, Gregory Smedley, Olav B.

Publication number: 20080015488Abstract: The invention relates generally medical devices and methods for the treatment of glaucoma in an animal eye and, more particularly, to medical devices and methods for treating tissue of the trabecular meshwork and/or Schlemm's canal of the eye to restore or rejuvenate a portion or all of the normal physiological function of directing aqueous outflow for maintaining a normal intraocular pressure in the eye.Type: ApplicationFiled: September 25, 2007Publication date: January 17, 2008Applicant: GLAUKOS CORPORATIONInventors: Hosheng Tu, Gregory Smedley, Barbara Niksch, David Haffner

Publication number: 20070112292Abstract: 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: November 13, 2006Publication date: May 17, 2007Inventors: Hosheng Tu, Gregory Smedley, David Haffner, Barbara Niksch

Publication number: 20070010827Abstract: Surgical methods and related medical devices for treating glaucoma are disclosed. The method comprises trabecular bypass surgery, which involves bypassing diseased trabecular meshwork with the use of a stent implant. The stent implant is inserted into an opening created in the trabecular meshwork by a piercing member that is slidably advanceable through the lumen of the stent implant for supporting the implant insertion. The stent implant is positioned through the trabecular meshwork so that an inlet end of the stent implant is exposed to the anterior chamber of the eye and an outlet end is positioned into fluid collection channels at about an exterior surface of the trabecular meshwork or up to the level of aqueous veins.Type: ApplicationFiled: June 19, 2006Publication date: January 11, 2007Inventors: Hosheng Tu, David Haffner, Gregory Smedley, Barbara Niksch, Morteza Gharib
