Abstract
A multi-part tool assembly for harvesting and implanting follicular units, comprising an outer cannula having an open, tissue-piercing distal end, and an inner cannula coaxially positioned in a lumen of the first cannula, the second cannula having an open, tissue-coring distal end sized to engage and retain single hair follicular units. An obturator may be positioned in the lumen of the second cannula, wherein at least one of the first cannula, second cannula, and obturator are movable relative to the other ones.
Claims15
An apparatus for harvesting and implanting hair follicular units, comprising:
- an outer implanting cannula having an interior lumen and an open, tissue-piercing distal end configured for implanting a follicular unit into an implant region;
- and
- an inner harvesting cannula positioned coaxially in the implanting cannula lumen, the inner harvesting cannula having an open, tissue-coring distal end and an interior lumen sized to engage and retain a follicular unit,
- wherein the harvesting and implanting cannulas are moveable relative to each other in a reciprocating relationship, and wherein when harvesting hair follicular units, the distal end of the implanting cannula is located proximal to the distal end of the harvesting cannula.
An apparatus for harvesting and implanting follicular units, comprising:
- an outer implanting cannula having an open, tissue-piercing distal end and an interior lumen;
- a harvesting cannula positioned in the interior lumen of the implanting cannula, the harvesting cannula having an open, tissue-coring distal end and an interior lumen respectively configured and sized to excise and retain a follicular unit;
- and
- an obturator positioned in the interior lumen of the harvesting cannula,
- wherein at least one of the implanting cannula, harvesting cannula, and obturator is movable relative to another one of the implanting cannula, harvesting cannula, and obturator, and wherein when harvesting hair follicular units, the distal end of the implanting cannula is located proximal to the distal end of the harvesting cannula.

- a harvesting cannula positioned in the interior lumen of the implanting cannula, the harvesting cannula having an open, tissue-coring distal end and an interior lumen respectively configured and sized to excise and retain a follicular unit;
- and
- an obturator positioned in the interior lumen of the harvesting cannula,
- wherein the implanting cannula, harvesting cannula, and obturator are coaxially aligned along a common axis and movable relative to one another, and wherein when harvesting hair follicular units, the distal end of the implanting cannula is located proximal to the distal end of the harvesting cannula.
