Patent ID: 8454907

Claim:
Apparatus for obtaining growth factors comprising: a reservoir having an open end portion, a closed end portion, and a mount for stabilizing said reservoir, a reciprocating member positioned in said open end portion to define a chamber within said reservoir between said reciprocating member and said closed end portion, said reciprocating member movable to selected positions within said reservoir relative to said closed end portion to increase and decrease the volume of said chamber, a locking mechanism formed in said reservoir to engage said reciprocating member in a predetermined position in said reservoir to fix the volume of said chamber for applying a negative pressure to the growth factor starting material, a throughbore extending through said reciprocating member for communication with said reservoir and having at one end a sealable inlet extending out of said reservoir to receive growth factor starting material for introduction into said chamber, a cap for closing said sealable inlet to said throughbore, said cap removable from said sealable inlet for introduction of growth factor starting material into said throughbore to said chamber, said cap engageable with said sealable inlet to seal said throughbore and said chamber to allow for the formation of negative pressure within said chamber, said cap removable from said sealable inlet to unseal said throughbore and said chamber, a device connected to said reciprocating member for moving said reciprocating member with said cap engaging said sealable inlet to a position within said reservoir to increase the volume of said chamber to create negative pressure applied to the growth factor starting material within said chamber to separate the growth factors from the growth factor starting material, and said sealable inlet with said cap removed therefrom operable as an outlet for extracting the growth factors from said chamber.
