Process and system employing a method to control pressures when removing, handling, and reinjecting adipose tissue
The invention is a method and control system to manage pressure levels during reinjection procedures of viable soft tissue. Although this case specifically relates to its use in the reinjection of adipose fat and other tissue back into the body during harvesting and reinjection procedures, it can be applied to any medical procedure of introducing or re-introducing materials into the body.
1 - 20 . (canceled)
21 . Apparatus for regulating pressure levels of a reinjected adipose tissue after harvesting of said tissue from a patient during a liposuction procedure, comprising the following:
an aspiration cannula;
a filtration device for processing said tissue after aspiration thereof;
a pump for pressurizing said tissue in a reinjection cannula; and
a pressure sensor coupled to said reinjection cannula and adapted to control a pressure level in the reinjection cannula by varying operating parameters of said pump.
22 . The apparatus of claim 1 , wherein said pump is a peristaltic pump and said sensor is an in-line sensor.
23 . The apparatus of claim 2 , wherein said in-line sensor is configured to detect a pressure increase through an increased load on the pump.
