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.

1. A method for isolation of one or more connective tissue proteins from one or more fat containing tissues comprising the steps of: harvesting the fat containing tissue obtained by liposuction, abdominoplasty, or any other fat removal techniques, in a jacketed vessel comprising:a sonic probe, an outer jacket and a mesh filter, wherein the sonic probe and the mesh filter are inside the jacketed vessel, wherein the jacketed vessel further comprises:a first inlet that allows passage of the one or more fat containing tissue into an interior of the jacketed vessel, which comprises a cooling jacket comprising a cooling inlet and a cooling outlet, wherein the sonic probe in the jacketed vessel capable of generating an acoustic pulses capable of disrupting the fat containing tissue in the jacketed vessel, a mesh filter capable of separating stromal vascular lipids in the jacketed vessel by filtration and in fluid communication with a first outlet, a second inlet in fluid communication with the interior of the jacketed vessel for a washing fluid during the filtration, and a second outlet in fluid communication with the interior of the jacketed vessel for isolation of isolated connective tissue protein by the filtration;flowing the fat containing tissue into the jacketed vessel, wherein the jacketed vessel is an acoustically permeable closed system;exposing directly the fat containing tissue to one or more acoustic pulses in the jacketed vessel to separate the one or more connective tissue proteins from a stromal vascular fraction (SVF), wherein the SVF comprises lipids, cells, or any other extracellular elements pass through the mesh filter; thereby isolating the separated connective tissue proteins from the fraction that did not traverse the mesh filter. 2. The method of claim 1, wherein the isolated connective tissue protein comprises collagen type I. 3. The method of claim 1, wherein the one or more fat containing tissues is adipose tissue. 4. The method of claim 1, wherein the acoustic pulses comprise ultrasonic waves. 5. The method of claim 1, wherein the method of isolating the connective tissue proteins is performed under sterile conditions. 6. The method of claim 1, wherein a frequency for the one or more ultrasonic pulses ranges from 40-500 kHz. 7. The method of claim 1, wherein a pore size of the filter ranges from 5 microns-300 microns. 8. The method of claim 1, wherein the fat containing tissue is heterologous tissue. 9. The method of claim 1, further comprising the step of morselizing the isolated connective tissue proteins. 10. A method for isolation of one or more connective tissue proteins from one or more fat containing tissues harvested by liposuction, abdominoplasty, or any other fat removal techniques comprising the steps of: introducing the fat containing tissue comprising the one or more connective tissue proteins into a jacketed vessel, the jacketed vessel comprising:a sonic probe, an outer jacket and a mesh filter, wherein the sonic probe and the mesh filter are inside the jacketed vessel, wherein the jacketed vessel further comprises:a first inlet that allows passage of the one or more fat containing tissue into an interior of the jacketed vessel, which comprises a cooling jacket comprising a cooling inlet and a cooling outlet, wherein the sonic probe in the jacketed vessel is capable of generating acoustic pulses capable of disrupting the fat containing tissue in the jacketed vessel, a mesh filter capable of separating stromal vascular lipids in the jacketed vessel by filtration and in fluid communication with a first outlet, a second inlet in fluid communication with the interior of the jacketed vessel for a washing fluid during the filtration, and a second outlet in fluid communication with the interior of the jacketed vessel for isolation of isolated connective tissue protein by the filtration;acoustically separating the connective tissue proteins from the fat containing tissues in the jacketed vessel; thereby isolating in the jacketed vessel the separated connective tissue proteins by filtration from a fraction that did not traverse the mesh filter. 11. The method of claim 10, wherein the isolated connective tissue protein comprises collagen type I. 12. The method of claim 10, wherein the one or more fat containing tissues is adipose tissue. 13. The method of claim 10, wherein the acoustic pulses comprise ultrasonic waves. 14. The method of claim 10, wherein the method of isolating the connective tissue proteins is performed under sterile conditions. 15. The method of claim 10, wherein a frequency for the one or more ultrasonic pulses ranges from 40-500 kHz. 16. The method of claim 10, wherein a pore size of the filter ranges from 5 microns-300 microns. 17. The method of claim 10, wherein the fat containing tissue is heterologous tissue. 18. The method of claim 10, further comprising the step of morselizing the isolated connective tissue proteins. 19. A method for isolation of one or more connective tissue proteins from one or more fat containing tissues comprising the steps of: harvesting the fat containing tissue by liposuction, abdominoplasty, or any other fat removal techniques, in a jacketed vessel comprising:a sonic probe, an outer jacket and a mesh filter, wherein the sonic probe and the mesh filter are inside the jacketed vessel, wherein the jacketed vessel further comprises:a first inlet that allows passage of the one or more fat containing tissue into an interior of the jacketed vessel, which comprises a cooling jacket comprising a cooling inlet and a cooling outlet, wherein the sonic probe in the jacketed vessel is capable of generating acoustic pulses capable of disrupting the fat containing tissue in the jacketed vessel, a mesh filter capable of separating stromal vascular lipids in the jacketed vessel by filtration and in fluid communication with a first outlet, a second inlet in fluid communication with the interior of the jacketed vessel for a washing fluid during the filtration, and a second outlet in fluid communication with the interior of the jacketed vessel for isolation of isolated connective tissue protein by the filtration;flowing the fat containing tissue into the jacketed vessel, wherein the jacketed vessel is an acoustically permeable closed system;exposing directly the fat containing tissue to one or more acoustic pulses at between 40-500 kHz in the jacketed vessel to separate the one or more connective tissue proteins from a stromal vascular fraction (SVF), wherein the SVF comprises lipids, cells, or any other extracellular elements pass through the mesh filter; thereby isolating the separated connective tissue proteins from the fraction that did not traverse the mesh filter. 20. The method of claim 19, wherein the isolated connective tissue protein comprises collagen type I. 21. The method of claim 19, wherein the one or more fat containing tissues is adipose tissue. 22.
