Abstract
Official abstract text for this publication.
Methods and apparatus are provided for affecting an appearance of skin by harvesting small portions of tissue from a donor (first) site and applying them at a recipient (second) site. A plurality of micrografts can be formed from a piece of graft tissue and attached to a dressing material. The dressing material can then be expanded to increase a separation distance between the micrografts, and the dressing material having spaced-apart micrografts attached thereto can be applied to a prepared recipient site. An apparatus can be provided that expands the dressing material using a pressurized fluid. A further method can include providing a suspension of small portions of graft tissue in a solution. The solution can be injected into blisters formed at a recipient (second) site and the tissue portions allowed to attach and proliferate. A method and apparatus can also be provided for forming corresponding blisters at a donor site and at a recipient site. The raised (removed) portions of the blisters can be removed and attached to a dressing material, and the portions from the donor (first) site can be placed onto the exposed blister areas at the recipient site.
First claim
Opening claim text (preview).
What is claimed is: 1. An apparatus for producing suction blisters, comprising: an arrangement comprising at least one elongated channel extending across a plate and longitudinally intersecting a lower surface of the plate, the lower surface extending parallel to the at least one elongated channel and configured to provide a seal between the plate and a skin surface; and a conduit configured to provide a vacuum source in a pressure communication with the at least one elongated channel to form the suction blisters. 2. The apparatus of claim 1 , wherein the arrangement comprises a plurality of channels, and wherein a distance between at least two adjacent ones of the channels is less than 4 mm. 3. The apparatus of claim 1 , wherein the arrangement comprises a plurality of channels, and wherein a distance between at least two adjacent ones of the channels is 2 mm. 4. The apparatus of claim 1 , wherein the arrangement comprises a plurality of intersecting channels, the plurality of intersecting channels including the at least one elongated channel. 5. The apparatus of claim 1 , wherein the conduit perpendicularly intersects the at least one elongated channel. 6. An apparatus for producing suction blisters, comprising: an arrangement comprising at least one elongated channel intersecting a lower surface of a plate and forming a blister pattern provided in a lower portion thereof; and a conduit intersecting one of the at least one elongated channels, the conduit configured to provide a vacuum source in a pressure communication with the at least one elongated channel to form suction blisters, having the blister pattern, in skin. 7. An apparatus for producing suction blisters, comprising: an arrangement comprising at least one elongated channel extending across a plate and longitudinally intersecting a lower surface of the plate, the lower surface configured to provide a seal between the plate and a skin surface; and a conduit configured to provide a vacuum source in a pressure communication with the at least one elongated channel, the conduit perpendicularly intersecting the at least one elongated channel to form the suction blisters.
