    摘要: Described herein is an IOP control device for implantation in an eye of a patient, comprising a drainage tube, a pressure-driven flow system, and a flow rate measurement system. The drainage tube includes a drainage lumen in fluid communication with an anterior chamber of the eye. The flow system is in fluid communication with the drainage lumen, and is configured to control the flow of fluid through the drainage tube. The flow rate measurement system is disposed distal to the flow system, and comprises a flow tube including a known hydraulic resistance to flow, a proximal pressure sensor disposed at the proximal end of the flow tube, and a distal pressure sensor disposed at the distal end of the flow tube. The flow tube includes a proximal end, a distal end, and a lumen extending therebetween that is configured to be in fluid communication with the drainage lumen.

    摘要: An implantable device for mechanically stimulating the trabecular meshwork is disclosed. The device is implanted in the eye adjacent the trabecular meshwork. The device imparts mechanical stimulating in the form of vibrations or movement to the trabecular meshwork. The imparted mechanical stimulation causes the trabecular meshwork to move in a manner that produces a pumping action to remove aqueous from the anterior chamber of the eye.

    摘要: An intraocular device for implantation in an eye of a patient is provided. The intraocular device includes an inlet tube, an outlet tube, and a microfluidic chamber. The microfluidic chamber includes a chamber inlet coupled to the inlet tube, a chamber outlet coupled to the outlet tube, and one or more fluidic barriers. Each fluidic barrier is configured such that, as a fluid is injected into the microfluidic chamber, a front of the fluid coincides with the fluidic barrier before any of the fluid passes beyond the fluidic barrier. Associated methods are also disclosed herein.
