Abstract

A fluid transfer assembly includes first and second connector members, each associated with a fluid conduit and having a meltable wall which normally seals the connector member, and thus the associated conduit. The connector members can be coupled together, with the meltable walls positioned in facing contact. One of the meltable walls includes a radiant energy absorbing material. The other meltable wall is relatively non-absorbant of radiant energy, but does conduct heat energy. By exposing the coupled assembly to a source of radiant energy, the one wall melts in response to thermal radiation, while the other wall conducts heat energy from the melting wall to also melt. By melting, the walls open a fluid path between the fluid conduits.
