  • Patent number: 10369079
    Abstract: Embodiments of the present invention involve a refill apparatus comprising at least one pump, a plurality of reservoirs, a plurality of reservoir fluid channels each associated with one of the reservoirs, a plurality of valves, each having a cracking pressure, for fluidically sealing the reservoir fluid channels and the outlet fluid channel, an outlet fluid channel fluidically connected to the reservoir fluid channels, and a needle having a lumen in fluid communication with the outlet fluid channel. A parameter such as a pressure level is monitored, and one or more pumps and various ones of the valves are actuated in accordance with a protocol comprising a sequence of steps whereby fluidic pathways are opened between different ones of the reservoirs and the needle in a washing and filling sequence, each of the steps being associated with an expected pressure level.

  • Patent number: 10357899
    Abstract: Tubular polymeric structures are formed by creating a convex mold conforming to a fluid pathway design, depositing a coating of polymer over the mold, and in situ removing the mold without drawing it against the polymer. The resulting structures are fabricated with flow-altering features.

  • Patent number: 10240689
    Abstract: Microscale valves for use in, e.g., micropump devices, may be formed of a slitted diaphragm bonded o the interior of a valve tube. A bump in the diaphragm and/or a backward-leakage stopper may increase the breakdown pressure of the valve. A push-rod may be used to pre-load the valve membrane to thereby increase the cracking pressure.

  • Patent number: 9956340
    Abstract: An implantable device has an outer shell that includes an aperture through the housing of the device and, spanning the aperture, a membrane structure permeable to gas but not to liquid. In this way, excess gas may be vented from the device. The membrane and aperture are designed to discourage or even prevent tissue ingrowth.

  • Patent number: 9550023
    Abstract: A removable material is deposited or otherwise applied to a flat substrate surface in a pattern corresponding to desired corrugations in a membrane, e.g., a deflection diaphragm. The applied material serves as a scaffold for a polymeric material, which is applied thereover, and following cure or hardening, the polymeric material is removed to form a finished corrugated membrane.
