DEVICES AND METHODS FOR PERFORMING PROCEDURES ON A BREAST

摘要

A device for cutting tissue having a bowed cutting element may include a shaft having a central axis and a tissue cutting element coupled to the shaft. The tissue cutting element may be movable from a collapsed position to an expanded position and may bow outwardly when in the expanded position. The cutting element generally moves in a first plane when moving between the collapsed and expanded positions. The shaft may have a first thickness and a second thickness relative to the central axis of the shaft. The first and second thicknesses may lie in a second plane which is generally parallel to the first plane. The second thickness may be at least 1.25 times larger than the first thickness and the side of the shaft may have the second thickness leading the cutting element during rotation.
