Remote magnetic driven flow system
First Claim
1. A system for treatment of an ocular condition of a patient, comprising:
- a flow 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 passageway 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 flow device, the flow system including a regulator having a magnetic element, wherein the regulator comprises a flexible membrane being displaceable in the fluid flow passageway to affect flow through the fluid flow passageway, the magnetic element forming a rigid portion that is part of the flexible membrane; and
a control device physically separate from the flow device and configured to be disposed outside the eye, the control device comprising a magnetic field generating actuator configured to act on the magnetic element to adjust the regulator in the flow system to selectively adjust flow through the flow device in response to changes in intraocular pressure.

Abstract
A system for implantation in an eye of a patient includes a flow device sized for implantation into the eye of the patient. The flow device includes a fluid flow passageway and a flow system. The flow system may include a regulator having a magnetic element, and may be displaceable in the fluid flow passageway to affect flow through the fluid flow passageway. The system may also include a control device physically separate from the flow device and configured to be disposed outside the eye, the control device comprising an actuator magnetic field generator configured to act on the magnetic element to adjust the regulator in the flow system to selectively adjust flow through the flow device in response to changes in intraocular pressure.

17. A method of regulating fluid flow from an anterior chamber of an eye, comprising:
-
directing fluid through an implantable flow device including a housing defining a fluid flow passageway and including a flow system comprising a flexible membrane having a magnetic element that forms part of the flexible membrane and is responsive to a control device, wherein the control device is physically separate from the flow device and is configured to be disposed outside the eye to adjust flow through the fluid flow passageway; and modifying an amount of drainage through the implantable flow device by creating a magnetic field with the control device. - View Dependent Claims (18, 19, 20)
