Device and method for preparing tissue, particularly adipose tissue

摘要

A device and a method for preparing adipose tissue for transplantation from lobular fat extracted, for instance by liposuction, the fat including a fluid component that have an oily component, a blood component and/or sterile solutions, and a solid component including cell fragments, cells and one or more cell macroagglomerates of heterogeneous size, wherein the device includes at least one washing and separating container having a washing chamber, the container has an inlet and an outlet for the liposuctioned material to enter the washing chamber through the inlet and for at least part of the material to exit the washing chamber through the outlet, the washing chamber including stirring means for forming an emulsion of fluid components.

1. A method of preparing adipose tissue for transplantation from lobular fat extracted from a body, said fat comprising a fluid component comprising one or more of an oily component, a blood component, or sterile solutions, and a solid component comprising cell fragments, cells and one or more cell macroagglomerates of heterogeneous size, the method comprising the step of:
dividing said fat into cell agglomerates smaller than said cell macroagglomerates, thereby producing said cell agglomerates that are as large as or smaller than a predetermined size, and said cell agglomerates that are on average of a same size; and reducing size by causing said extracted lobular fat to pass at least once through size reducing means (3) comprising a series of parallel or intersecting sheets or wires that form at least one size reducing net located in a washing and separating container (1) or a size-reducing container (2).
