摘要:
Disclosed are devices, methods and systems for treatment of eye disease such as glaucoma. Implants are described herein that enhance aqueous flow through the normal outflow system of the eye with minimal to no complications. The implant can include reversibly deformable portions that have a plurality of openings layered, covered or otherwise spanned by an elastomeric film or membrane having micropores. The micropores allow for fluid flow out of the implant while inhibit cellular infiltration and blockage of the openings.

Described herein are delivery devices and methods of using the devices for delivering an ocular implant into a suprachoroidal space without use of a goniolens. The delivery device includes a handle including a channel extending from a proximal end of the handle to a distal end of the handle, an applier coupled to the handle, the applier including a blunt distal tip and an elongate, flexible wire insertable through a fluid channel of an ocular implant, and a fiber optic image bundle reversibly inserted through the channel such that the fiber optic image bundle extends to a region proximal to the blunt distal tip of the applier.

Described herein is a delivery device and methods for delivering an ocular implant into an eye. The delivery device includes a proximal handle portion; a distal delivery portion coupled to a distal end of the handle portion and configured to releasably hold an ocular implant and includes a sheath positioned axially over a guidewire; and a metering system configured to provide visual guidance regarding depth of advancement of an implant positioned on the guidewire into an anatomic region of the eye. Also disclosed is a device and method for loading an implant onto the delivery device.

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.

This disclosure relates generally to methods and devices for use in viewing and positioning an eye with a gonio lens system, such as during ocular exams and ocular surgeries. Some embodiments of the gonio lens system can include a gonio lens for viewing one or more tissues and structures of the eye. In addition, the gonio lens system can include one or more positioning features for controlling movement positioning of the eye.
摘要:
Disclosed are devices and methods of treating an ocular disorder including forming a self-sealing incision in a cornea into an anterior chamber of an eye; introducing through the incision a fluid drainage tube having a distal end, a proximal end and a longitudinal, internal lumen extending through the fluid drainage tube, wherein at least the proximal end passes through the anterior chamber; and implanting the distal end of the fluid drainage tube in fluid communication with the suprachoroidal space such that the proximal end of the fluid drainage tube remains in fluid communication with the anterior chamber.
摘要:
A delivery system is disclosed which can be used to deliver an ocular implant into a target location within the eye via an ab interno procedure. In some embodiments, the implant can provide fluid communication between the anterior chamber and the suprachoroidal or supraciliary space while in an implanted state. The delivery system can include a proximal handle component and a distal delivery component. In addition, the proximal handle component can include an actuator to control the release of the implant from the delivery component into the target location in the eye.

Disclosed are devices and methods for treatment of eye disease. The suprachoroidal space is used as a conduit within which to place a drug delivery device. One such drug delivery device may be a tube, wicking element, bioabsorbable polymer structure, or other configuration of drug delivery substrate. The delivery device may include a port on the proximal end to assist in repeat injection, and may include a reservoir to either collect flow from the aqueous to concentrate it along the length of the device, or act as a repository for injected agent.

This disclosure relates generally to methods and devices for use in treating eye conditions with implantable drug delivery devices. One method includes introducing an implant into the suprachoroidal space, wherein the interior volume of the implant is plugged with a drug-release material comprising at least one active agent that elutes through at least one opening in the implant, wherein the drug-release material degrades from the interior volume of the implant over a period time.
