Abstract
A device for maintaining patency of a channel of an uveolymphatic region or a Schlemm's canal in a patient's eye may include a single elongated element configured for radial expansion of the channel of the uveolymphatic region or the Schlemm's canal when inserted into the channel, wherein the single elongated element is configured to follow an arc of a circumference of the channel, wherein the arc subtends an angle comprising a degree of arc greater than approximately 75 degrees.
Claims30
A method for delivering a stent into Schlemm's canal, the method comprising:
- a. detachably coupling a helical single elongated element to a pusher disposed inside a delivery device, wherein the helical single elongated element is configured to radially expand when inserted into a channel of the Schlemm's canal;
- b. advancing the helical single elongated element into the channel;
- c. adjusting the advancement of the helical single elongated element into the channel;
- and
- d. uncoupling the helical single elongated element from the pusher;
- e. wherein the delivery device is configured to block retraction of the helical single elongated element.
A system for delivering a stent into Schlemm's canal, the system comprising:
- a. at least one helical single elongated element configured for radial expansion when inserted into a channel of the Schlemm's canal;
- b. a pusher detachably coupled to the at least one helical single elongated element and disposed in a delivery device, wherein the pusher is configured to control advancement, retraction, and adjustment of the at least one helical single elongated element in the channel;
- c. wherein the delivery device is configured to uncouple the pusher from the at least one helical single elongated element when the at least one helical single elongated element reaches a predetermined location in the channel.
