Abstract:
1. A method of collecting and in situ processing of aspirated fat tissue sampled from a human patient, said method comprising the steps: (a) providing a surgeon with a powered-assisted hand-held fat tissue aspiration instrument having a cannula, and a fat tissue sampling, processing and collection device installed between said power-assisted hand-held fat aspiration instrument and a vacuum source, wherein said fat tissue sampling, collection and processing device includes a suction plate, mounted within a collection chamber, and for supporting the open proximal ends of a plurality of tissue collection and processing tubes, wherein each said tissue collection and processing tube has micro-pores formed in the side walls thereof, and its distal end opening is capped; (b) selecting a first tissue collection and processing syringe in said tissue sampling, processing and collection device to be filled with a first sample of fat tissue aspirated by said cannula from a first specified location in the body of said patient; (c) using said powered hand-held fat tissue aspiration instrument to aspirate fat tissue from said human patient, collect said first sample of aspirated fat tissue in said first tissue collection and processing syringe selected in step (b), and allow fluid to flow and filter through said micro-pores as aspirated fat tissue flows through the cannula of said power-assisted hand-held fat aspiration instrument, and one or more selected tissue collection and processing tubes mounted on said suction plate, during tissue aspiration operations; (d) selecting a second tissue collection and processing syringe in said tissue sampling, processing and collection device to be filled with a second sample of fat tissue aspirated by said cannula from a second specified location in the body of said patient; (e) using said hand-held powered fat tissue aspiration instrument to aspirate fat tissue from said human patient and collecting said second sample of aspirated fat tissue in said second tissue collection and processing tube selected in step (d), and allow fluid to flow and filter through said micro-pores as aspirated fat tissue flows through the cannula of said power-assisted hand-held fat aspiration instrument, and one or more selected tissue collection and processing tubes mounted on said suction plate, during tissue aspiration operations; and (f) removing said first and second fat tissue collection and processing tubes from said fat tissue sampling, processing and collection device, after completion of fat tissue aspiration operations.
