Devices and methods are provided for extracting and macerating tissue, and
optionally for depositing the tissue onto a tissue scaffold. The device
generally includes an outer tube having a substantially open distal end
that is adapted to be placed on and preferably to form a seal with a
tissue surface, and a shaft rotatably disposed within the outer tube and
movable between a first, proximal position in which the shaft is fully
disposed within the outer tube, and a second, distal position in which a
portion of a distal end of the shaft extends through the opening in the
distal end of the outer tube. The device also includes a tissue
harvesting tip formed on the distal end of the shaft that is effective to
excise a tissue sample when the shaft is moved to the distal position,
and a cutting member that is coupled to the shaft at a position proximal
to the tissue harvesting tip. The cutting member is effective to macerate
a tissue sample excised by the tissue harvesting tip.
