PASSIVE TO ACTIVE STAGED DRAINAGE DEVICE

摘要

Described herein is an IOP control system for implantation in an eye of a patient, comprising a drainage device and a control device. The drainage system includes a housing including an inlet port and an outlet port, a fluid flow passageway extending from the inlet port to the outlet port to allow the flow of fluid therethrough, and at least one valve disposed within the housing. The at least one valve includes a first side and an opposing second side, and is configured to affect flow through the fluid flow passageway from the inlet port to the outlet port by moving in response to pressure differentials acting on the opposing sides. The control device comprises an actuator including an activated mode and a deactivated mode, and the actuator in the activated mode is configured to selectively adjust flow through the drainage device in response to changes in intraocular pressure.

1. An IOP control system for implantation in an eye 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 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; andat least one valve disposed within the drainage device, the at least one valve including a first side, an opposing second side, the at least one valve configured to affect flow through the fluid flow passageway from the inlet port to the outlet port by moving in response to pressure differentials acting on the opposing first and second sides; and a control device sized for implantation into the eye of the patient and comprising an actuator including an activated mode and a deactivated mode, wherein the actuator in the activated mode is configured to selectively adjust flow through the drainage device in response to changes in intraocular pressure.
