  • Microfluidic manifold for shear sensitive fluids
    Patent number: 9784396
    Abstract: A microfluidic device is provided. A manifold having a first channel, a second channel, and a third channel configured to transport blood can be coupled to a substrate defining an artificial vasculature. The first channel can be configured to carry blood in a first direction. Each of the second and third channels can couple to the first channel at a first junction and can be configured to receive blood from the first channel. The second channel can be configured to carry blood in a second direction away from the first direction. The third channel can be configured to carry blood in a third direction away from the second direction. The first, second, and third channels can be non-coplanar.

  • Methods for reducing the blood priming volume and membrane surface area in microfluidic lung assist devices
    Patent number: 9180239
    Abstract: A device and method for oxygenating blood is disclosed herein. The device includes a plurality of passive mixing elements that causes a fluid to mix as it flows through the device. The passive mixing elements continually expose new red blood cells to the portion of the flow channel where oxygenation can occur. Accordingly, in some implementations, the device and method uses less blood to prime the device and allows for the oxygenation of blood with a substantial shorter flow channel when compared to conventional oxygenation methods and devices.

  • ENDOVASCULAR PLATFORMS FOR UNIFORM THERAPEUTIC DELIVERY TO LOCAL TARGETS
    Publication number: 20110313508
    Abstract: An endovascular platform is provided that includes a periodic tiling-based stent structure having a parallelogram tile associated with a fundamental domain and an intrinsic cell-shape. A lattice vector includes a section of the parallelogram tile where the lattice vector is circumferentially folded to create helical repetition of cells.
