Patent ID: 7004198

Claim:
A microfluidic interconnect comprising: a first substrate comprising: a first upper surface and an opposed first lower surface; a cavity disposed in the first lower surface, the cavity having a first bounding surface, and a first fluidic opening disposed on the first bounding surface; a first fluidic pathway disposed within the first substrate, fluidicaily connected to the first fluidic opening; a second substrate comprising: a second upper surface and an opposed second lower surface; an extension disposed on the second upper surface, the extension having a second bounding surface and a second fluidic opening disposed on the second bounding surface; a second fluidic pathway disposed within the second substrate, fluidically connected to the second fluidic opening; means for bonding the first lower surface of the first substrate to the second upper surface of the second substrate, the bonding means having a through hole, substantially aligned with the extension on the second upper surface of the second substrate; the extension and the cavity being dimensioned and spaced to interfit, fluidically connecting the first fluidic opening to the second fluidic opening, thereby fluidically connecting the first fluidic pathway in the first substrate with the second fluidic pathway in the second substrate.
