Abstract

Systems and methods for preparation of an implant and ab interno insertion of the implant into an eye of a patient including a tissue cartridge configured to receive and hold a patch of a material; a cutting device; and a delivery device. Related devices, systems, and methods are provided.

Claims (42)

1. A system for ab interno insertion of an implant into an eye of a patient, the system comprising:

an implant comprising a solid strip of a material having no internal lumen;

a tissue cartridge comprising a nose cone fixedly coupled to a distal shaft comprising a lumen, the implant located within the lumen of the distal shaft, wherein at least a distal end region of the shaft is sized and shaped for insertion into an anterior chamber of the eye and atraumatic dissection of a cyclodialysis cleft between a sclera and a ciliary body of the eye; and

a delivery device configured to reversibly couple with the tissue cartridge via a proximal end region of the nose cone for deployment of the implant from the lumen into the cyclodialysis cleft.

2. The system of claim 1 , further comprising a cutting device, wherein the cutting device comprises a cutting member configured to cut a patch of the material into the implant.

3. The system of claim 2 , wherein the delivery device comprises an actuator configured to deploy the implant through the lumen of the shaft into the eye.

4. The system of claim 1 , wherein the shaft of the tissue cartridge is configured to deliver a viscous material.

5. A system for preparation of an implant from a patch of a material and ab interno insertion of the implant into an eye of a patient, the system comprising:

a tissue cartridge comprising a nose cone fixedly coupled to a distal shaft defining a lumen between the nose cone and a distal end region of the distal shaft, at least the distal end region of the distal shaft being sized and shaped for insertion into an anterior chamber of the eye;

a cutting device comprising a cutting member configured to cut the patch of the material into the implant; and

a delivery device configured to reversibly couple to the tissue cartridge via a proximal end region of the nose cone of the tissue cartridge and deploy the implant from the lumen of the distal shaft.

6. The system of claim 5 , wherein the cutting device comprises a base configured to receive the patch.

7. The system of claim 6 , further comprising a compacting tool configured to urge the implant into the lumen of the distal shaft.

8. The system of claim 7 , wherein the delivery device comprises an actuator configured to deploy the implant compacted within the lumen of the distal shaft into the eye.

9. A system for preparation of an implant and ab interno insertion of the implant into an eye of a patient, the system comprising:

a tissue cartridge comprising:

a nose cone comprising a proximal connector on a proximal end region and a distal end region; and

a distal shaft fixedly coupled to the distal end region of the nose cone, the distal shaft defining a lumen from a proximal end region to a distal end region of the distal shaft, at least the distal end region of the distal shaft being sized and shaped for insertion into an anterior chamber of the eye; and

a delivery device comprising a proximal handle having a distal end region defining a distal connector sized to engage and reversibly couple with the tissue cartridge via the proximal connector on the proximal end region of the nose cone.

10. The system of claim 9 , further comprising a cutting device, wherein the cutting device comprises a cutting member configured to cut a patch of a material into the implant.

11. The system of claim 9 , wherein the delivery device further comprises at least one actuator configured to deploy the implant, when positioned within the lumen of the distal shaft, out a distal opening and into the eye.

12. The system of claim 9 , wherein the shaft of the tissue cartridge is configured to deliver a viscous material.

13. A method of preparing an implant for implantation into, and of inserting said implant into, an eye of a patient, the method comprising:

cutting a patch of a material with a cutting member of a cutting device to form an implant from the patch;

compacting the implant within a lumen of a shaft fixedly coupled to a distal end of a tissue cartridge;

coupling at least a portion of the tissue cartridge to a delivery device;

inserting a distal end region of the shaft into the anterior chamber of the eye;

positioning the distal end region adjacent eye tissue; and

actuating the delivery device to deploy the implant from the tissue cartridge through at least a portion of the lumen such that the implant engages the eye tissue.

14. The method of claim 13 , further comprising delivering a viscous material through the shaft.

15. The system of claim 5 , wherein a distal-most tip of the distal shaft is configured to dissect tissue for implantation into the Schlemm's canal or trans-sclerally.

16. The system of claim 8 , further comprising a movable internal elongate member operatively coupled to the actuator to advance the implant through the lumen and out a distal opening of the distal shaft.

17. The system of claim 9 , wherein the proximal connector and the distal connector comprises a male-to-female connection.

18. The system of claim 11 , wherein the at least one actuator is configured to advance a tool from a first position at which the tool is retracted to a second position at which the tool inserts into the lumen behind the implant positioned within the lumen.

19. The system of claim 18 , wherein the at least one actuator is configured to withdraw the nose cone relative to the tool to cause the implant to be deployed out the distal opening.

20. The system of claim 18 , wherein the at least one actuator is configured to advance the tool relative to the nose cone to cause the implant to be deployed out the distal opening.

21. The system of claim 1 , wherein the delivery device comprises a proximal handle comprising a distal receptacle sized and shaped to receive the proximal end region of the nose cone.

22. The system of claim 21 , wherein the distal receptacle is keyed to receive the proximal end region in a first orientation and prevent the proximal end region from being received within the distal receptacle in another orientation that is different from the first orientation.

23. The system of claim 21 , wherein actuation of an actuator on the proximal handle retracts the tissue cartridge proximally further into the distal receptacle to deploy the implant.

24. The system of claim 23 , wherein the tissue cartridge retracts proximally relative to a stopper element positioned at least in part within the lumen of the distal shaft to deploy the implant through a distal opening of the distal shaft.

25. The system of claim 1 , wherein the material comprises minimally-modified biologically-derived material.

26. The system of claim 25 , wherein the biologically-derived material comprises scleral tissue.
