Expandable ocular devices
First Claim
1. A system for treating an ocular disorder in an eye, comprising:
- an ocular device comprising;
a proximal end, a distal end, and an internal lumen forming a flow pathway extending from the proximal end to the distal end wherein upon implantation in the eye the proximal end is configured to be in fluid communication with Schlemm'"'"'s canal of the eye and the distal end is configured to be in fluid communication with an anterior chamber of the eye;
at least one inflow region communicating with the flow pathway; and
an expandable portion comprising a plurality of interconnected struts forming multiple openings in the device that communicate with the flow pathway, wherein the expandable portion has a first diameter of a generally cylindrical first cross-sectional shape suitable for insertion into the eye through a self-sealing incision in the cornea and a second diameter of a second cross-sectional shape that is larger than the first diameter and sized to expand the general circumference of the surrounding tissue, the second cross-sectional shape being generally oval and configured to conform to the contour of the Schlemm'"'"'s canal and prevent rotation of the ocular device upon expansion; and
a delivery device for inserting the ocular device into an eye, the delivery device comprising;
a sheath configured to surround at least a portion of the ocular device;
an applier configured to insert into the internal lumen of the ocular device; and
an actuator.

Abstract
Disclosed herein are systems, devices and methods for treating an ocular disorder in an eye. The ocular device includes a proximal end, a distal end, and an internal lumen forming a flow pathway extending from the proximal end to the distal end; at least one inflow region that communicates with the flow pathway; and an expandable portion having a plurality of interconnected struts forming multiple openings in the device communicating with the flow pathway. The expandable portion has a first cross-sectional shape suitable for insertion into the eye that is generally cylindrical and a second cross-sectional shape that is larger than the first cross-sectional shape. The system also includes a delivery device for inserting the ocular device into an eye including a sheath configured to surround at least a portion of the ocular device; an applier configured to insert into the internal lumen of the ocular device; and an actuator.

18. A method for the surgical treatment of an ocular disorder in an eye, comprising:
-
coupling an ocular stent device to a delivery device comprising an applier, a sheath, and an actuator; forming a self-sealing incision in the cornea; introducing the ocular stent device into the anterior chamber of the eye through the incision using the delivery device, the ocular stent device comprising; a proximal end, a distal end, and an internal lumen forming a flow pathway extending from the proximal end to the distal end wherein upon implantation in the eye the proximal end is configured to be in fluid communication with Schlemm'"'"'s canal of the eye and the distal end is configured to be in fluid communication with an anterior chamber of the eye; an inflow region near the proximal end communicating with the flow pathway; and an expandable region comprising a plurality of interconnected struts forming multiple openings communicating with the flow pathway, wherein the expandable region has a first diameter of a generally cylindrical first cross-sectional shape suitable for insertion into the eye through the self-sealing incision in the cornea and a second diameter of a second cross-sectional shape that is larger than the first diameter and sized to expand the general circumference of the surrounding tissue, the second cross-sectional shape being generally oval and configured to conform to the contour of the Schlemm'"'"'s canal and prevent rotation of the ocular device upon expansion; inserting the distal end of the ocular stent device into a tissue structure near an anterior angle of the eye such that the inflow region remains in communication with the anterior chamber and at least a portion of the expandable region is positioned within the tissue structure; expanding the expandable region; and conducting aqueous humor from the anterior chamber towards the tissue structure. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26)
