Patent ID: 6935617

Claim:
A valve assembly comprising: a substrate including; a first surface; a first recess formed in the first surface; a second recess formed in the first surface; and a recessed channel that is recessed relative to the first surface of the substrate and extending from the first recess to the second recess, the recessed channel being at least partially defined by a first deformable material having a first modulus of elasticity; an elastically deformable cover including; a layer of an elastically deformable material having a modulus of elasticity that is greater than the modulus of elasticity of the first deformable material; and an adhesive layer in contact with the first surface of the substrate; wherein the elastically deformable cover covers the recessed channel and forms a fluid communication between the first and second recesses when the elastically deformable cover layer is in a non-deformed state.
