Methods and devices for cutting and collecting soft tissue
First Claim
1. A method of cutting breast tissue for removal, comprising the steps of:
- providing a tissue cutting device having an elongate cutting element and a tissue collection element mounted to an elongate element which is spaced apart from the cutting element, the cutting element being movable between a bowed position and a retracted position, the cutting element having a radially outer side and a radially inner side;
introducing the tissue cutting device into a breast;
moving the elongate cutting element to the bowed position;
coupling a power source to the elongate cutting element; and
rotating the cutting element after the moving step so that the cutting element cuts the breast tissue, wherein the radially outer side has a larger surface area for transmitting energy to cut the tissue than the radially inner side, the elongated element positioned so that tissue collection element prevents contact between the breast tissue and a portion of the radially inner side of the cutting element.
