DEFINITION

Classification: 427/2.3

Fluid barrier or fluid transporting product, other than merely absorbing (e.g., surgical glove, condom, lined diaper, membrane filter, IV tubing, cannula, dialysis membrane, urinary catheter):

(under subclass 2.1) Processes in which the product contains a component which is intended to act as a barrier for a fluid or a fluid portion of a composition or which is intended to function as a fluid transporting means, other than a product functioning by merely sorbing the fluid; parts, subcombinations, or intermediates thereof or therefor.

(1) Note. The product must be intended to function as defined, not just be incidentally a fluid barrier, for example, as might be the case for a simple plaster medical or surgical cast which may provide some liquid resistance but which is not formulated for liquid proofing.
