Abstract:
1. A method for aspirating and introducing a body tissue, comprising: introducing a drill tip attached at a distal end of an aspiration cannula into a bone marrow cavity through an entry port defined along the cavity, wherein the cannula has a flexible length which is deflectable in all directions relative to a proximal end of the length which is coupled to a handle; advancing the aspiration cannula along a first path within the cavity while rotating the drill tip, wherein the drill tip comprises a proximal portion that is tapered in a distal direction from a proximal end of the drill tip and a distal portion having a rounded blunt tip, where the drill tip terminates at the rounded blunt tip such that the drill tip moves sideways upon encountering a surface of a cortical bone within the cavity without causing trauma to the surface; inhibiting damage to the body tissue while rotating the drill tip; aspirating a portion of the body tissue into the aspiration cannula having the flexible length, wherein the cannula is introduced into the body tissue through the entry port defined along the cavity containing the body tissue; processing the aspirated body tissue to enrich at least one population of cells contained therewithin; and introducing the enriched at least one population of cells into a tissue region of interest.
