Abstract

System and methods for isolation of collagen and other fibrous tissue from adipose tissue are described herein. The method of the present invention isolates the collagen from adipose tissue by sonication. The tissue to be sonicated is placed in a container or a flow cell transparent to ultrasound waves. After sonication the sonicated material is filtered out through the bottom of the flow cell and the sonicated collagen is trapped in the filter, which may be taken for further processing. The isolated collagen can then be combined with a suitable carrier for re-injection to correct various tissue defects such as wrinkles, to form a carrier for the stem cells, a filler, and matrix for new collagen production by injecting into the desired area of the host.
