Abstract
A system and method for harvesting autologous tissue, mincing it into fragments that are visible and measureable 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.
Claims10
A method of tissue repair comprising:
- cutting tissue to create tissue fragments;
- aspirating fluid and the tissue fragments through a cannulated shaft of a resection system to a filter assembly, the resection system comprising a handpiece having a proximal end, a distal end, and a passageway therethrough, the cannulated shaft being attached to the distal end of the handpiece in fluid communication with the passageway, the 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;
- and
- separating the tissue fragments having a pre-selected size from the fluid using the filter.
