The invention is a process and system, consisting of a reinjection pump, connecting tubing, a reinjection cannula and a recipient site, with fluid management features including a peristaltic pump head and controls for pressure limits, flow rates and flow distribution wherein the process of controlling the reinjected fat and fluid is unique because of the control of flow rates, pressures, matching cannula hole sizes, and maintaining a closed continuous system where the harvesting and reinjection is done all together with a completely closed system. The process utilizes 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 liposuction procedures, it can be applied to any medical procedure of introducing or re-introducing materials into the body.
A process and system of parts that make up a system to transfer adipose tissue with fluid management features, comprising the following:
A process and system of parts that make up a system to transfer adipose tissue with fluid management features, comprising the following:
A process and system of parts that make up a system to transfer adipose tissue with fluid management features, comprising the following:
The flow distribution of any of the preceding claims wherein the frequency of the stop and go motion and the speed of rotation of the motor are set by the user through the reinjection pump.
The recipient site of any of the preceding claims wherein the recipient site is a location(s) in the patient undergoing the reinjection procedure.
The process and system of parts of any of the preceding claims wherein the flexible tubing is made from one continuous piece.
The process and system of parts of any of the preceding claims wherein the flexible tubing is made from one or more sections of tubing.
The pressure limit of any of the preceding claims wherein the monitoring of internal pressure extends to the recipient site, since any given internal pressure of the flexible tubing is also the pressure of the fluid just exiting the cannula into the recipient site.
Dependencies are inferred from the claim text.
