Abstract
A method of and apparatus for photo-activating a collected sample of fat tissue including stem cells therein, contained in a tissue collection and processing device. The collected fat tissue sample including stem cells therein, is exposed to low levels of photo-active light energy while contained within the tissue collection and processing device. The tissue sample is photometrically-measured to determine the photo-activation index of the fat tissue sample. The Photo-active light energy emission is controlled to ensure optimized photo-activation, thereby providing the fat tissue sample with an improved capacity to bind free oxygen species in the fat tissue sample.

A method for photo-activating a collected sample of fat tissue including stem cells therein, contained in a tissue collection and processing device, comprises the steps of:
- (a) exposing the collected fat tissue sample including stem cells therein, to low levels of photo-active light energy while contained within said tissue collection and processing device;
- (b) photometrically-measuring said tissue sample to determine the photo-activation index of said fat tissue sample;
- and
- (c) controlling said photo-active light energy emission to ensure optimized photo-activation providing said fat tissue sample with an improved capacity to bind free oxygen species in said fat tissue sample.
A photo-activation instrument system for treating samples of fat tissue, comprising:
- a photometrically-controlled photo-activation chamber installed within a housing, and having arrays of visible light emitting diodes (LEDs) and/or visible laser diodes (VLDs);
- wherein a sealed tissue collection and processing device containing a fat tissue sample can be inserted into said photometrically-controlled photo-activation chamber, and said fat tissue sample undergo automatically-controlled photo-activation treatment by low levels of photo-active light energy having photo-active wavelengths emitted from said arrays of visible light emitting diodes (LEDs) and/or said visible laser diodes (VLDs) surrounding the sealed tissue collection and processing device, while a photo-activation index (PAI) of said fat tissue sample is photometrically-measured between periodically-alternating modes of photo-activation, and used to control said arrays of visible light emitting diodes (LEDs) and/or said visible laser diodes (VLDs) so as to ensure that said fat tissue sample is optimally photo-activated, and over-activation is avoided.
15-22. (canceled)
A method of computing a photo-activation index (PAI) for a tissue sample including stems cells therein, before, during and after photo-activation treatment of said tissue sample including said stem cells, said method comprising the steps of:
- (a) transmitting red wavelengths of light into the tissue sample and measuring the transmitted or reflected response over the field of view (FOV) of a common photo-diode;
- (b) transmitting IR wavelengths of light into said tissue sample and measuring the transmitted or reflected response over the field of view (FOV) of the common photo-diode;
- and
- (c) processing the detected/measured red and IR light signal intensities so as to compute a Photo-Activation Index (PAI) that provides a logarithmic ratio of red and IR photon affinities in the tissue specimen, before, during or after said photo-activation treatment of said tissue sample.
