Uveoscleral shunt and methods for implanting same
First Claim
Patent Images
1. A system for treating an ocular disorder in a patient, comprising:
- a drainage implant which, following implantation at an implantation site, conducts fluid from the anterior chamber to a uveoscleral outflow pathway of an eye; and
a delivery instrument for implanting the drainage implant, said instrument having a distal end sufficiently sharp to penetrate eye tissue at an insertion site near the limbus of the patient'"'"'s eye, and being sufficiently long to advance the implant transoccularly from the insertion site across the anterior chamber to the implantation site, wherein at least the distal end of the delivery instrument is flexible, a distal end portion having a non-linear shape, said instrument having a sufficiently small cross section such that the insertion site self seals without suturing upon withdrawal of the instrument from the eye, said instrument being comprised of plural members longitudinally moveable relative to each other and a seal between said members to prevent aqueous humor from passing between the members proximal the seal when the instrument is in the eye,wherein the seal is integral with one of the plural members.
