    摘要: Microfluidic normally closed check valves and methods of making and using the same are provided. The check valves include an orifice, an occluding portion, and one or more attachment members which urge the occluding portion into a position occluding the orifice. In various embodiments, the attachment member or members are pre-stressed by thermal annealing to introduce tensile stress of at least 800 PSI therewithin, thereby increasing the cracking pressure of the valve

    摘要: An implantable glaucoma drainage device (GDD) system is disclosed. The GDD system comprises a microflow control system for controlling intraocular pressure, a protective capillary carrier tube housing the microflow control system, and anchoring arms holding the implanted device in place. The overall GDD size can be in a needle-implantable form factor for minimally invasive implantation. The GDD may be implanted via subconjunctival needle implantation to mimic the normal aqueous humor drainage pathway.
