Ocular implant delivery systems
First Claim
1. An ocular implant system, comprising:
- an ocular implant, the implant comprising an elongated body, the elongated body including;
an inlet port arranged on a proximal end segment of the implant to communicate with an anterior chamber of an eye;
an inner lumen communicating with the inlet port;
a plurality of outlet ports located on a distal end portion of the ocular implant, the plurality of outlet ports being in communication with the inner lumen and configured to drain aqueous humor out of the anterior chamber of the eye; and
one or more retention features arranged to contact ocular tissue;
wherein the ocular implant comprises polyimide material; and
wherein the ocular implant is tubular; and
a delivery device comprising;
an elongated member carrying the ocular implant and being configured for ab interno insertion of the ocular implant, the elongated member having a distal portion, the distal portion being curved at least when deployed in the eye for accessing a target tissue site in an anterior chamber angle within the eye with the elongated member extending through an opening into the anterior chamber of the eye disposed apart from the target tissue site; and
a handpiece, wherein the handpiece comprises an actuator and a spring, the spring being disposed within the handpiece and being operably coupled to the actuator such that actuation of the actuator causes at least partial unloading of the spring when deploying the ocular implant,wherein both the curved distal portion of the elongated member and the inner lumen of the ocular implant have a circular cross-section, andwherein the curved distal portion of the elongated member is further configured to make an opening through ocular tissue at the target tissue site.

Abstract
Systems and methods for treating ocular disorders are disclosed. One system has a delivery instrument, with a non-linear axis, configured to be inserted into an anterior chamber of an eye and moved to a location proximate a physiologic outflow pathway of the eye. The delivery instrument carries an implant that has a distal end sized for insertion into tissue such that aqueous humor drains from the anterior chamber to the physiologic outflow pathway. One method involves inserting a non-linear portion of a delivery device into the anterior chamber to position an implant within the eye. Another method involves using a delivery device with a curved distal portion to implant an implant at a location communicating with the physiologic outflow pathway. The delivery can be through a corneal incision and the implant can comprise a drug.

10. An ocular implant system, comprising:
-
an implantation instrument having a curved distal end portion configured to access eye tissue in an anterior chamber angle of an eye in an ab interno manner, wherein a distal tip of the curved distal end portion is configured to create an opening in eye tissue; and an ocular implant configured to be disposed in the opening in eye tissue, the ocular implant comprising an elongated body, the elongated body including; an inlet port configured to communicate with an anterior chamber of the eye; an inner lumen communicating with the inlet port; and a plurality of outlet ports located along a distal end portion of the ocular implant, the plurality of outlet ports being in communication with the inner lumen; wherein the ocular implant comprises polyimide material; wherein the ocular implant is tubular; wherein a portion of an outer surface of the ocular implant comprises a ribbed surface; wherein both the curved distal end portion of the implantation instrument and the inner lumen of the ocular implant have a circular cross-section; wherein the implantation instrument comprises a handpiece; and wherein the handpiece comprises an actuator and a spring, the spring being disposed within the handpiece and being operably coupled to the actuator such that actuation of the actuator causes at least partial unloading of the spring when deploying the ocular implant. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
