Abstract
A system and method for harvesting autologous tissue, mincing it into fragments that are visible and measurable when filtered, and delivering a portion of the tissue back into the patient without the need to directly touch the tissue. During the same surgical procedure, the tissue can be mixed with a biocompatible agent before introduction into the repair site.
Claims16
A tissue collection assembly comprising:
- a handpiece having a proximal end, a distal end, and a passageway therethrough;
- a cannulated shaft attached to the distal end of the handpiece in fluid communication with the passageway, a distal end of the shaft configured to receive tissue fragments;
- and
- a filter assembly removeably attached to the proximal end of the handpiece in fluid communication with the cannulated shaft via a tube extending from the proximal end of the handpiece such that a distal end of the filter assembly is spaced apart from the proximal end of the handpiece, the filter assembly comprising:
- a housing allowing direct visualization of an internal volume of the housing;
- and
- a filter disposed within the internal volume of the housing for collecting the tissue fragments on a surface of the filter.
