Tissue dissociation device

摘要

A tissue dissociation device ( 10 ) includes a container ( 12 ) having a sterile interior for holding the tissue to be dissociated and a liquid medium. The device ( 10 ) also includes a dissociation element ( 54 ), inside the container ( 12 ), for engaging the tissue to cause dissociation of the tissue. The device ( 10 ) also includes a resistive element ( 81 ), inside the container ( 12 ), for resisting movement of the tissue in response to the engagement by the dissociation element ( 54 ). Relative motion between and the resulting resistance provided by the resistive element ( 81 ) allows the dissociation element ( 54 ) to effectively dissociate the tissue. A powered tissue dissociation device includes a power source operatively connected to the dissociation element ( 54 ) for causing the dissociation element ( 54 ) to move into engagement with the tissue
