Patent ID: 8900251

Claim:
A method of using a radial deployment surgical tool comprising: providing a radial deployment surgical tool comprising an outer shaft, an inner shaft and a functional head, the outer shaft having a distal end and a proximal end and the inner shaft having a distal end and a proximal end; operably attaching the functional head to the distal end of the inner shaft, wherein the functional head comprises a plurality of cleaning head arms, wherein each cleaning head arm comprises a main arm portion and a tip portion, wherein the main arm portion has a first arm section and a second arm section and wherein the tip portion is oriented at an angle with respect to a part of the main arm portion to which the tip portion is attached; inserting at least a portion of an inner shaft in the outer shaft; positioning the functional head in a refracted position substantially within the outer shaft; placing the distal end of the outer shaft in an opening in a patient; moving the functional head to an extended position where at least a portion of the functional head extends outside of the outer shaft so that the cleaning head arms extend to a diameter that is greater than a diameter of the outer shaft, wherein when the functional head is in the extended position, the first arm section is oriented in a distal direction and the second arm section is oriented in a proximal direction; rotating the inner shaft to cause the tip portions to engage tissue; moving the functional head to the retracted position, wherein the tip portions retain the engaged tissue in engagement as the functional head moves to the retracted position; and withdrawing the radial deployment surgical tool from the patient to remove the engaged tissue from the patient.
