Abstract:
1. A device for obtaining a biopsy tissue sample comprising: (a) a handle including a rod with a first proximal end and a first distal end, where the rod has a first principal axis of rotation, where the first principal axis of rotation intersects with both the first proximal end of the rod and the first distal end of the rod; (b) a head including a cone tapering from a second proximal end to a second distal end such that a line that follows a two dimensional projection of the cone taper from the second proximal end to the second distal end is not parallel with the first principal axis, where the head is attached to the first distal end of the rod; (c) one or more facets associated with the head, where a first facet of the one or more facets has a surface contour that differs from the contour of the head, where the surface contour of said first facet has a positive radius of curvature, where the first facet is cut at an angle relative to the first principal axis of rotation of the rod of between: (d) an abrasive material made up of fenestrated loops, where the abrasive material is attached to at least the first facet.
