Sutureless guided skin biopsy system
A skin biopsy system covers all aspects of the biopsy procedure from initial incision to final closure. The system includes a flexible closure consisting of 4 elongated rigid members interconnected by flexible hinges. The opening within the closure is initially diamond-shaped, approximating an ellipse, which is then deformed or pinched to a narrow linear opening when the wound is closed. Included with the system is a knife which interacts with the closure to yield a guided incision of constant depth. The path of the knife is guided by interference between the blade and the inside faces of the closure while the depth is limited by interference of the handle proximal the blade and the top faces of the closure.

Artificial dermis and production method therefor
Artificial dermis (1) obtained from plasma with platelets (2) and human fibroblasts. The plasma with platelets (2) is obtained from the fractionating of total blood (4) from the patient (8) by light centrifugation, and the human fibroblasts (3) from a skin biopsy (5). Clotting is obtained by adding calcium. This artificial dermis (1) provides for the rapid growth of the keratinocytes (6) seeded on its surface to build an artificial skin (7) which can easily be transplanted. Large areas of artificial dermis (1) are obtained from a small skin biopsy (5) and minimal quantities of plasma with platelets (2), which being enriched with cytokines and platelet growth factors, strengthens the proliferation of the cells seeded, both inside and on the surface. The artificial skin (7) obtained can be used to treat major burn treatments, chronic skin ulcers, etc., or be used, by employing genetically altered cells, as a vehicle for gene therapy.
