Method and apparatus for tissue harvesting

An apparatus comprising:

• a hub;
• a housing including a recess;
• a plurality of harvesting needles coupled to the hub, each of the plurality of harvesting needles configured to penetrate skin tissue, wherein the hub is configured to fit in the recess of the housing and the hub is removably coupled to the housing to facilitate removal of the plurality of harvesting needles;
• a base configured to be placed on a surface of the skin tissue, the base configured to form an enclosed volume above the surface of the skin tissue;
• wherein a distal end of each of the plurality of harvesting needles is structured to be inserted into the skin tissue to remove at least one portion of the skin tissue therefrom when each of the plurality of harvesting needles is withdrawn from the skin tissue;
• wherein when the plurality of harvesting needles are in a retracted state, the plurality of harvesting needles do not protrude from a lower surface of the base;
• and
• wherein when the plurality of harvesting needles are pulled downward, the plurality of harvesting needles protrudes beyond the lower surface of the base.

An apparatus comprising:

• a housing;
• a hub;
• a first harvesting needle coupled to the hub, the first harvesting needle configured to penetrate a skin tissue;
• a second harvesting needle coupled to the hub, the second harvesting needle configured to penetrate the skin tissue;
• and
• wherein the hub is removably coupled to the housing to facilitate removal of the first harvesting needle and the second harvesting needle therefrom;
• wherein a first distal end of the first harvesting needle is structured to be inserted into the skin tissue to remove a first portion of the skin tissue therefrom when the first harvesting needle is withdrawn from the skin tissue;
• and
• wherein a second distal end of the second harvesting needle is structured to be inserted into the skin tissue to remove a second portion of the skin tissue therefrom when the second harvesting needle is withdrawn from the skin tissue.

An apparatus comprising:

• a housing;
• a first harvesting needle configured to penetrate a skin tissue, a first distal end of the first harvesting needle being structured to be inserted into the skin tissue to remove a first portion of the skin tissue therefrom when the first harvesting needle is withdrawn from the skin tissue;
• a second harvesting needle configured to penetrate the skin tissue, a second distal end of the second harvesting needle is structured to be inserted into the skin tissue to remove a second portion of the skin tissue therefrom when the second harvesting needle is withdrawn from the skin tissue;
• a base coupled to the housing, the base including a rim, the base being configured to be placed on a surface of the skin tissue, the rim being configured to rest on the surface of the skin tissue, the base including a recess defined by the rim, the recess being configured to form an enclosed volume above the surface of the skin tissue;
• wherein when the first harvesting needle and the second harvesting needle are in a retracted state, the first harvesting needle and the second harvesting needle do not protrude from a lower surface of the base;
• and
• wherein when the first harvesting needle and the second harvesting needle are pulled downward, the first harvesting needle and the second harvesting needle protrude beyond the lower surface of the base.
