  • Patent number: 7879079
    Abstract: 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.

  • Patent number: 7488303
    Abstract: An implant for treating an ocular disorder has a longitudinal implant axis, an outflow portion passing therethrough, a plurality of longitudinally spaced openings therein, an inflow portion, and an anchoring member that extends from the implant and is disposed distally of the openings. The outflow portion is shaped and sized to be introduced into Schlemm's canal of an eye at an angle, and received at least partially within Schlemm's canal regardless of its rotational orientation about the axis during introduction. The openings allow fluid communication from a lumen within the outflow portion to a location outside the outflow portion. The inflow portion is configured to be positioned within an anterior chamber of the eye to permit fluid communication from the anterior chamber to the outflow portion. The axis extends through a trabecular meshwork of the eye and is generally orthogonal to Schlemm's canal during the fluid communication.

  • Patent number: 6533764
    Abstract: Apparatus for instilling a medicament into an eye includes a housing having a longitudinal axis and a chamber disposed in the housing for containing a medicament. A nozzle is provided for instilling a dose of medicament into an eye and an actuator meters doses of medicament from the chamber to the nozzle and forces each metered dose through the nozzle upon axial displacement of the actuator along housing longitudinal axis. A spring causes the axial displacement of the actuator upon release of the spring from a compressed state. A collar disposed for rotation about the housing longitudinal axis is provided by compressing the spring by twisting the collar about the housing longitudinal axis and a trigger disposed in a housing is provided for releasing the compressed spring.

  • Patent number: 6254579
    Abstract: Apparatus for instilling a medicament into an eye includes a rigid housing for containing a reservoir of medicament and a nozzle for instilling a dose of the medicament into an eye. A displacement pump, sealing a front end of the rigid housing and in fluid communication with the reservoir, provides for metering doses of medicament from the reservoir to the nozzle and for forcing each metered dose through the nozzle. A stopper, slidably disposed within a rear end of the rigid housing, provides for gradually decreasing the housing volume containing the medicament reservoir. A diaphragm provides for accommodating transient decreases in the volume containing the medicament reservoir during metering of doses therefrom by the displacement pump.
