Abstract
Methods and devices are adapted for implanting into the eye. An incision is formed in the cornea of the eye and a shunt is inserted through the incision into the anterior chamber of the eye. The shunt includes a fluid passageway. The shunt is passed along a pathway from the anterior chamber through the scleral spur of the eye into the suprachoroidal space and positioned in a first position such that a first portion of the fluid passageway communicates with the anterior chamber and a second portion of the fluid passageway communicates with the suprachoroidal space to provide a fluid passageway between the suprachoroidal space and the anterior chamber.
Claims20
An ocular implant system, comprising:
- an ocular implant comprising an elongate core member,
- wherein the elongate core member comprises an outer surface, and
- wherein the elongate core member comprises a plurality of helical or spiral flow channels defined along the outer surface of the elongate core member;
- and
- a delivery instrument, comprising:
- a hand-held component;
- and
- an elongated applier operatively coupled to the hand-held component wherein the elongated applier has an internal lumen and wherein the ocular implant is positioned inside the internal lumen, the elongated applier having a proximal region aligned with a longitudinal axis of the hand-held component and a distal region curved away from the longitudinal axis, wherein the delivery instrument is configured to:
- pass the ocular implant across the anterior chamber past the scleral spur near the ciliary body of the eye towards the supraciliary space opposite the incision in the cornea;
- and
- position the ocular implant from inside the anterior chamber such that a proximal end of the ocular implant is in the anterior chamber and a distal end of the ocular implant is in fluid communication with the supraciliary space.
An ocular implant system, comprising:
- an ocular implant comprising an elongate core member,
- wherein the elongate core member comprises an outer surface, and
- wherein the elongate core member comprises a plurality of straight flow channels defined along the outer surface of the elongate core member, wherein the plurality of straight flow channels are arranged circumferentially around the outer surface of the elongate core member;
- and
- a delivery instrument, comprising:
- a hand-held component;
- and
- an elongated applier operatively coupled to the hand-held component wherein the elongated applier has an internal lumen and wherein the ocular implant is positioned inside the internal lumen, the elongated applier having a proximal region aligned with a longitudinal axis of the hand-held component and a distal region curved away from the longitudinal axis, wherein the delivery instrument is configured to:
- pass the ocular implant across the anterior chamber past the scleral spur near the ciliary body of the eye towards the supraciliary space opposite the incision in the cornea;
- and
- position the ocular implant from inside the anterior chamber such that a proximal end of the ocular implant is in the anterior chamber and a distal end of the ocular implant is in fluid communication with the supraciliary space.
An ocular implant system, comprising:
- an ocular implant comprising an elongate core member,
- wherein the elongate core member is a porous or sponge-like member without a lumen;
- and
- a delivery instrument, comprising:
- a hand-held component;
- and
- an elongated applier operatively coupled to the hand-held component wherein the elongated applier has an internal lumen and wherein the ocular implant is positioned inside the internal lumen, the elongated applier having a proximal region aligned with a longitudinal axis of the hand-held component and a distal region curved away from the longitudinal axis, wherein the delivery instrument is configured to:
- pass the ocular implant across the anterior chamber past the scleral spur near the ciliary body of the eye towards the supraciliary space opposite the incision in the cornea;
- and
- position the ocular implant from inside the anterior chamber such that a proximal end of the ocular implant is in the anterior chamber and a distal end of the ocular implant is in fluid communication with the supraciliary space.
