Abstract

A system being suitable for being secured substantially adjacent to a surface of a subject so as to effect delivery of at least one substance through the surface and into the subject. The system includes at least one aperture for receiving at least one ultrasonic transmission. The at least one substance is releasably secured substantially adjacent to the at least one aperture. A sonic member is disposed with respect to the at least one aperture so as to communicate the at least one transmission to the at least one substance so as to effect the delivery of the at least one substance through the surface of the subject.

Claims

1. A system being suitable for being secured substantially adjacent to a surface of a subject so as to effect delivery of at least one substance through said surface and into said subject responsively to a sonic applicator being positioned proximate thereto and generating at least one sonic transmission, comprising:

a substantially planar backing sheet having at least one aperture that receives the at least one sonic transmission, said at least one substance being releasably secured substantially adjacent to said at least one aperture; and

,

a sonic membrane disposed across said at least one aperture and between the sonic applicator and at least one substance, so as to communicate said at least one sonic transmission to said at least one substance and effect said delivery of said at least one substance through said surface of said subject.

2. The system of claim 1, further comprising:

a pad releasably securing said at least one substance substantially adjacent to said at least one aperture.

3. The system of claim 2, further comprising a patch, distinct from the sonic applicator and comprising the backing sheet, sonic membrane and pad.

4. The system of claim 3, wherein the patch further comprises a sonically activated semi-permeable membrane substantially adjacent to the pad and that provides a sonically activated valving function.
