Abstract
A medical device for severing and removing small amounts of internal tissue for biopsy sampling or other purposes is disclosed. Versions of the device may include a hollow probe having a piecing tip, a tissue receiving aperture and a vacuum lumen; a cutter within the probe having a cutting edge that moves past the tissue receiving aperture, and a cutter driver mechanism. A cutter for use with versions disclosed herein may include an angled cutting tip and a cutting edge having a concave grind. Versions of the device also may include an aspirator fluidly connected to the vacuum lumen, coordinated operation of the aspirator and the cutter driver mechanism, and a fluid management system. Versions described may be used for removing multiple samples of tissue during a single insertion of the probe proximate to a target tissue mass.
