A liquid transport device and method are disclosed, for controlled liquid flow. The device contains opposed surfaces providing a controlled capillary flow zone, each surface including means for directing flow along predetermined paths and at least one surface including means to permit liquid introduction between the surfaces. At least a portion of the paths of one surface form a positive angle with respect to the paths of the directly opposing portion of the other surface, whereby controlled multidirectional flow of liquid introduced between the surfaces occurs with a predetermined peripheral configuration.

A liquid transport device for controlled fluid flow comprising two fixedly mounted opposing surface areas substantially all portions of which are spaced apart throughout a zone of intended liquid transport a distance no greater than will maintain a capillary flow of liquid introduced therebetween, and means to permit the introduction of liquid between said surfaces, each of said surfaces including, across at least a portion thereof, means for directing capillary flow of introduced liquid along predetermined paths, said directing means on the respective surfaces being relatively oriented so that the paths directed by a substantial portion of one of said surfaces form positive angles with respect to the paths directed by the directly opposing portion of the other surface, whereby capillary flow of liquid between said surfaces occurs in a controlled multidirectional manner with a predetermined peripheral configuration.
