Abstract:
1. A microfluidic device, comprising: a microfluidic valve assembly comprising a structure defining a microfluidic fluid path having a cross-sectional dimension of less than 1 mm, wherein the structure comprises a deformable material; and an actuator integrally connected to at least a portion of the structure such that separation of the actuator from the structure requires at least the use of tools and would cause damage to at least one component of the microfluidic device, the actuator movable between at least a first position causing relatively lesser constriction of the fluid path, a second position causing relatively greater constriction of the fluid path, and a third position causing complete constriction of the fluid path, wherein the actuator, when moved to the second or third position, is able to remain in the second or third position without application of energy to the actuator and without being susceptible to variations in the operable working environment of the assembly.
