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 comprising:

at least one aperture for receiving at least one ultrasonic transmission, said at least one substance being releasably secured substantially adjacent to said at least one aperture; and

,

a sonic member disposed with respect to said at least one aperture so as to communicate said at least one transmission to said at least one substance so as to effect said delivery of said at least one substance through said surface of said subject.

2. 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 comprising:

a backing layer;

at least one aperture formed in said backing layer for receiving at least one ultrasonic transmission;

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

,

a sonic member disposed with respect to said at least one aperture so as to communicate said at least one transmission to said at least one substance so as to effect said delivery of said at least one substance through said surface of said subject.
