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.
Claims20
A tissue collection assembly comprising:
- a resection system 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 comprising a cutting end;
- and
- a filter assembly removeably attached to the proximal end of the handpiece in fluid communication with the cannulated shaft, 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 tissue on a surface of the filter.

A tissue collection assembly and delivery device combination comprising:
- a tissue collection assembly comprising:
- a resection system comprising:
- a handpiece having a proximal end, a distal end, and a passageway therethrough;
- a cannulated shaft attached to the handpiece in fluid communication with the passageway, a distal end of the shaft comprising a cutting end;
- and
- a filter assembly removeably attached to the handpiece in fluid communication with the passageway, the filter assembly comprising:
- a housing allowing direct visualization of an internal volume of the housing;
- a filter removeably disposed within the internal volume of the housing for collecting tissue on a surface of the filter;
- and
- a compressor extendable through the internal volume of the housing for compressing the collected tissue;
- and
- a delivery device coupled to a coupling portion of the housing for delivering the collected tissue to a repair site.

A method of collecting and delivering tissue to a repair site, the method comprising:
- contacting a blade of a tissue collection assembly with tissue and cutting the tissue with a cutting end of the blade to create tissue fragments;
- aspirating fluid and the tissue fragments through the blade to a filter assembly, the filter assembly comprising:
- a housing allowing direct visualization of an internal volume of the housing, the housing in fluid communication with the blade;
- a filter removeably disposed within the internal volume of the housing for collecting the tissue fragments on a surface of the filter;
- and
- a compressor extendable through the internal volume of the housing for compressing the tissue fragments;
- and
- a shearing member slidably disposed around the filter for removing the collected tissue from the filter;
- separating the tissue fragments having a pre-selected size from the fluid using the filter;
- detaching the filter assembly from the blade;
- removing the filter from housing, thereby causing the shearing member to shear the tissue fragments from the surface of the filter;
- coupling the filter assembly to a delivery device;
- and
- inserting a plunger through the filter assembly and the delivery device to deliver the tissue fragments to a repair site.
