Abstract

Methods, devices, and systems are presented for inserting an implant in the cornea of the eye, where the implant is a microshunt; a microshunt delivery device for delivering the microshunt into the cornea may comprise the microshunt, an actuator, and a suction stabilizer; a vacuum device may be inserted in the stabilizer such that the cornea may be sucked onto a concave bottom side of the stabilizer; the microshunt may then be inserted into a hole in the suction stabilizer with the actuator; the actuator may be turned to screw the microshunt into a hole in the cornea; and the actuator may be removed from the suction stabilizer, breaking the vacuum seal and leaving the microshunt inserted in the cornea.

Claims15

Dependent claims

A microshunt delivery system comprising:

a microshunt comprising:
an inlet section comprising at least one lumen and at least one inlet opening;
an outlet section comprising at least one lumen that connects to at least one outlet opening;
a head with at least one slot;
a helical cutting threading around the periphery of the microshunt;
a nanofilter;
a wire;
an actuator comprising:
a helical shaft;
a knob;
a coupling arrangement comprising a concave end portion, the concave end portion including a rib with a gap for insertion into the at least one slot of the head of the microshunt;
a suction stabilizer comprising:
a body having a plurality of implantation holes;
at least one suctioning hole;
a suctioning ring;
wherein at least one implantation hole of the plurality of implantation holes is configured to be aligned with a hole in a cornea;
wherein a vacuum device is configured to be inserted into the at least one suctioning hole, suctioning the cornea to a concave underside of the suction stabilizer;
and
wherein the head of the microshunt is configured to couple to the actuator, and the knob is configured to turn to move the microshunt through one of the plurality of implantation holes configured to screw the microshunt into the hole in the cornea.
