Abstract:
1. A punch for removing targeted hair follicles from surrounding body tissue, and comprising: a generally cylindrical body formed about a generally central axis and extending distally from a proximal cutting end, the body having a follicle-receiving chamber defined by an interior wall within the generally cylindrical body extending distally from the proximal cutting end, the proximal cutting end of the punch having a generally curved concave exterior segment on a lateral surface of the generally cylindrical body, the generally curved concave exterior segment terminating proximally in a cutting edge having an outer diameter selected from the range of approximately 0.5 to approximately 5 mm, the generally curved concave exterior segment positioned so that tissue surrounding the targeted follicles outward of the cutting edge can expand against the concavity as the tissue is passed by the cutting edge to yield a substantially-inverted wound upon follicle extraction.
