Patent ID: 8571648

Claim:
A system to treat a biological tissue, comprising: means for stretching a biological tissue having a substance on a surface and a target below the surface; and means for relaxing the biological tissue to draw the substance from the surface into the biological tissue; and wherein the means for stretching comprises: a vacuum source; a vacuum conduit within a housing, the vacuum conduit coupled to the vacuum source; a controller coupled to the vacuum source to apply a vacuum to stretch the surface; and wherein the housing includes a first substance supplier through which the substance is applied onto the surface of the biological tissue and wherein the housing has an opening to receive the biological tissue; and wherein the means for relaxing comprises the controller which is configured to stop applying the vacuum to remove the stretching of the surface of the biological tissue after the substance is applied onto the surface; and wherein the controller coupled to the vacuum source is configured to apply the vacuum to stretch the surface that includes an epidermis that opens pathways in the epidermis, and exposes an inner surface of the target including sebaceous glands through the pathways, and wherein the controller is configured to provide the stretching that when removed generates a force that pushes the substance from the epidermis further down to the sebaceous glands.
