Debris clearance system for an ocular implant
First Claim
1. An IOP control system for treatment of an ocular condition of a patient, comprising:
- a drainage device sized for implantation into the eye of the patient and including;
a housing including an inlet port and an outlet port;
a fluid flow pathway extending through the housing from the inlet port to the outlet port to allow the flow of fluid from the inlet port to the outlet port; and
a flow system disposed within the drainage device and including a displaceable portion forming a part of the fluid flow pathway, the displaceable portion being displaceable via a magnetic field; and
an actuation system physically separate from the drainage device and configured to cooperate with the displaceable portion to overextend the displaceable portion via the magnetic field to set free buildup or debris in the flow pathway;
wherein the displaceable portion is displaceable in a first direction to an extended position by a pressure difference between an inlet pressure at the inlet port and an outlet pressure at the outlet port and is displaceable in the first direction to an overextended position by the magnetic field.

Abstract
An IOP control system for treatment of an ocular condition includes a drainage device sized for implantation into the eye of the patient, the drainage device including a fluid flow pathway to allow the flow of fluid from an inlet port to an outlet port. The drainage device also includes a flow system disposed within the drainage device and including a displaceable portion forming a part of the fluid flow pathway, the displaceable portion being displaceable via a magnetic field. An actuation system may be physically separate from the drainage device and may be configured to cooperate with the displaceable portion to displace the displaceable portion via the magnetic field to set free buildup or debris in the flow pathway.

9. An TOP control system for treatment of an ocular condition of a patient, comprising:
-
a drainage device sized for implantation into the eye of the patient and including; a housing including an inlet port and an outlet port; a fluid flow pathway extending through the housing from the inlet port to the outlet port to allow the flow of fluid from the inlet port to the outlet port; and a flow system disposed within the drainage device and including a displaceable portion forming a part of the fluid flow pathway, the displaceable portion being displaceable via a magnetic field and biased to a position that blocks fluid flow through the outlet port; and an actuation system physically separate from the drainage device and configured to cooperate with the displaceable portion to overextend the displaceable portion via the magnetic field to set free buildup or debris in the flow pathway; wherein the displaceable portion is displaceable in a first direction to an extended position by a pressure difference between an inlet pressure at the inlet port and an outlet pressure at the outlet port and is displaceable in the first direction to an overextended position by the magnetic field. - View Dependent Claims (10, 11)
