摘要:
Device and method for rapid extraction of body tissue from an enclosed body cavity. Hollow entry cannula with optional core element provides entry into body tissue space such as bone marrow. Aspiration cannula is inserted through the hollow entry cannula into the body tissue and is manipulated to advance directionally through the body cavity. Optional stylet within the aspiration cannula aids in advancing the aspiration cannula through the body tissue and is removed to facilitate extraction of the body tissue through the aspiration cannula. Inlet openings near distal tip of the aspiration cannula allow tissue aspiration, with negative pressure source at the proximal end of the aspiration cannula providing controlled negative pressure. The aspiration cannula may be withdrawn and its path adjusted for multiple entries through a same entry point, following different paths through the body tissue space for subsequent aspiration of more tissue.
