Self-trephining implant and methods thereof for treatment of ocular disorders
First Claim
1. A method of treating an ocular disorder, comprising:
- providing an ocular drainage implant having a proximal end and a distal section with a distal end;
forming a first opening to access an anterior chamber of an eye of a mammal;
advancing the ocular drainage implant through the first opening and into the anterior chamber of the eye, said ocular drainage implant having a maximum cross-sectional dimension sized to fit through the first opening;
transporting the ocular drainage implant through at least a portion of the anterior chamber with the distal end of the ocular drainage implant leading the proximal end of the ocular drainage implant and positioning at least the distal end of the ocular drainage implant within an anterior chamber angle of the eye;
forming, from within the anterior chamber, a second opening in eye tissue in the anterior chamber angle using the distal end of the ocular drainage implant; and
advancing the distal end of the ocular drainage implant through the second opening such that at least a portion of the distal section of the ocular drainage implant extends into and along a portion of a physiologic outflow pathway.

Abstract
Implants and methods for treating ocular disorders are disclosed. One implant has a tubular member, with inlet and outlet ends, and a cutting member connected thereto. The tubular member is configured to extend through eye tissue such that the inlet and outlet ends reside respectively in an anterior chamber and a physiologic outflow pathway of the eye. Desirably, the cutting member is configured to make an incision in the eye tissue for receiving at least a portion of the tubular member. One method involves introducing an implant, with proximal and distal ends, into the anterior chamber and penetrating eye tissue using an implant distal portion. The implant is advanced from the anterior chamber into the penetrated eye tissue to locate the distal and proximal ends respectively in the physiologic outflow pathway and the anterior chamber. Aqueous humor is conducted between the proximal and distal ends.
