  • Patent number: 11432731
    Abstract: The invention relates to endovascular medical implant devices, systems and methods that including a sensing device and a flow diverter device, which are effective to monitor intra-/post-operative hemodynamic properties in the location of a cerebral aneurysm and, hemodynamic alterations following placement of the system for treating ischemic diseases in carotid, coronary and peripheral arteries. The sensing device includes wireless, non-thrombogenic, highly stretchable, ultra-low profile flow sensors.
    Type: Grant

  • Publication number: 20120202972
    Abstract: An embodiment can be the use of motor proteins for cargo loading and transport in nano-devices and systems. One embodiment of the use of motor proteins can be adding biotin-binding proteins to a substrate by patterning, binding biotinylated F-actin to the biotin-binding proteins, aligning the bound F-actin in a preferred direction using a flow field, and using myosin coated particles to transport items attached to the particle throughout the substrate. Another embodiment of the use of motor proteins can be adding biotin-binding proteins to a substrate by patterning, adding a flow field, injecting F-actin so that the F-actin is bound and aligned simultaneously, and using myosin coated particles to transport items attached to the particle throughout the substrate. In either embodiment the F-actin can be capped with a biotinylated cap before binding to the biotin-binding proteins.
