Abstract: Devices and methods for assessing coagulation include a channel configured such that shear stress, in a first portion of the channel, applied to blood drawn through the channel by a vacuum-tube attached to an outlet of the channel approximates physiological shear stresses.

Abstract: A hybrid clamshell system encapsulates two of the six sides of an electronic circuit board to provide a high heat density solution and environmental protection. The clamshell enclosures seal to both sides of the PCB and contain fluid shut-off couplings. A two-phase cooling system directs a coolant via a supply path located in the sidewall of the enclosure to one or more cooling modules and collects the coolant via a return path within the enclosure. With the addition of an inject/eject mechanism attached to the clamshell, the fully assembled blade can be “fluid hot-swapped” in and out of the chassis with negligible loss of coolant. The interrelation of the clamshell module and it's implementation in an exemplary system are detailed herein.
