Systems and methods for harvesting, storing and implanting hair grafts
A system and method for harvesting, storing, and implanting biological units, in particular hair follicular units (FUs). The system is particularly useful to facilitate hair transplant procedures. The system may comprise an implanting tool, a cartridge with a plurality of receptacles for biological units and one or more control mechanisms. The device and cartridge for storing biological units may be incorporated within an overall automated or robotic system, or may form part of a semi-automated or even manual apparatus.
1. An automated process for shuttling a biological unit into and from a storage device having a plurality of receptacles, comprising:
acquiring a biological unit into a first tool using a substantially automated process;
urging the biological unit from the first tool into a selected receptacle of the storage device using a substantially automated process;
capturing the biological unit in the selected receptacle; and
displacing the biological unit from the selected storage device receptacle into the first tool or a different tool using a substantially automated process.
2. The process of claim 1 , wherein the first tool defines a lumen therethrough and the step of urging the biological unit through the first tool comprises applying a pressure differential to the first tool lumen.
3. The process of claim 2 , further comprising providing structure along a path in which the biological unit travels from the first tool to the storage device receptacle to reduce the pressure differential along a portion thereof and thereby reduce the speed of the biological unit along the path.
4. The process of claim 3 , wherein the structure comprises a parallel flow path outside of the path which terminates just before the path reaches the storage device.
5. The process of claim 1 , wherein the process includes applying a source of suction to a proximal side of the selected receptacle, and providing a pressure relief channel on the proximal side of each receptacle for limiting the maximum suction created within the receptacle to less than a suction magnitude of the source of suction.
6. The process of claim 1 , wherein the first tool defines a lumen therethrough and the step of urging the biological unit through the first tool comprises pushing the biological unit through the lumen of the first tool using mechanical means.
7. The process of claim 1 , further comprising cooling the biological unit while it is stored in the receptacle of the storage device.
8. The process of claim 1 , further comprising preserving the biological unit while it is stored in the receptacle of the storage device with a preservation solution.
9. The process of claim 1 , wherein at least some steps of the method are computer-controlled.
10. The process of claim 1 , wherein the storage device has a body with a thickness, the receptacles passing through the body between a first opening and a second opening on corresponding first and second ends of the receptacles, the storage device comprising a permissive medium covering the second ends of the receptacles.
11. The process of claim 1 , wherein displacing the biological unit from the storage device receptacle comprises pushing the biological unit from the receptacle using an obturator that enters the receptacle through the permissive medium.
12. The process of claim 1 , wherein the step of urging the biological unit through the removal tool comprises applying a pressure differential to the removal tool lumen by reducing the pressure at the second end of the receptacle relative to the first end by applying a low pressure source to the second end through the permissive medium.
13. The process of claim 1 , wherein the biological unit is a hair follicular unit.
14. The process of claim 12 , wherein the pressure at the second end of the receptacle is reduced relative to the first end by applying a low pressure source to the second end through the permissive medium.
15. The process of claim 12 , wherein the pressure at the second end of the receptacle is reduced relative to the first end by introducing a probe into the receptacle second end through the permissive medium, the probe providing a source of low pressure.
16. The process of claim 1 , wherein the step of acquiring comprises removing the biological unit from one location on a body surface into the first tool, wherein the first tool is a removal tool, and further implanting the biological unit from the removal tool or said different tool into another location on the body surface.
17. The process of claim 16 , wherein the removal tool or said different tool is an implanting tool, the implanting tool defining a lumen therethrough and the step of displacing comprises mechanical pushing of the biological unit into the implanting tool lumen.
18. The process of claim 16 , further including the steps of:
disengaging the removal tool from the storage device receptacle; and
engaging an implanting tool with the storage device receptacle.
