Abstract
A coiled shaft for tissue disruption is described herein where a flexible aspiration cannula has a first portion and a second portion formed of the coiled shaft. The cannula is configured in a particular embodiment to rotate over the length of the cannula to disrupt the matrix of bone marrow without the cannula buckling or collapsing. The cannula also includes a disruption tip coupled to the coiled shaft. The disruption tip has a radiused portion along a distal tip face of the disruption tip.
