Abstract
A needle is used to mark a tissue area of interest. The needle may have one or more indicators which indicate selected angular orientations relative to the needle. The indicators may also be coupled to anchors which are deployed in the tissue to anchor the needle in the tissue. The needle may be positioned to guide an excisional device to remove tissue.

24. A method of positioning a needle in a patient'"'"'s breast for a medical procedure, comprising the steps of:
-
providing a needle having at least one radially movable indicator for indicating a radial angular orientation when viewed along a longitudinal axis of the needle, the needle having a distal portion and a proximal portion;
positioning the distal portion in a patient'"'"'s breast with the proximal portion remaining outside the breast, radially moving the indicator to a radial position which provides an indication of a selected radial angular orientation relative to the longitudinal axis; and
performing a medical procedure using information from the selected angular orientation. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32)

33. A needle for introduction into a patient'"'"'s breast, comprising:
-
an elongate shaft having a longitudinal axis; and
a first indicator for indicating an angular orientation when viewed along the longitudinal axis of the shaft, the first indicator being radially movable by the user to a selected radial angular orientation relative to the longitudinal axis of the shaft. - View Dependent Claims (34, 35, 36, 37, 38, 39)

40. A method of excising breast tissue, comprising the steps of:
-
providing a guide element and a cutting device, the guide element having at least one radially movable indicator for indicating a radial angular orientation with respect to a longitudinal axis of the guide element, the cutting device having a deployable cutting element mounted on a shaft;
introducing the guide element into a patient'"'"'s breast;
advancing the cutting device into the patient'"'"'s breast, the cutting device being slidably coupled to the guide element so that the guide element guides the cutting device as the cutting device is advanced into the patient'"'"'s breast;
deploying a cutting element on the cutting device after the advancing step;
rotating the shaft so that the cutting element severs breast tissue; and
removing the breast tissue which has been severed by the cutting element. - View Dependent Claims (41, 42, 44, 45, 46, 47)

48. A system for removing breast tissue, comprising:
-
a guide element the guide element having a first radially movable indicator for indicating an annular orientation with respect to a longitudinal axis of the guide element; and
a cutting device, the cutting device having a deployable cutting element mounted on a shaft, the cutting device being configured to be slidably coupled to the guide element. - View Dependent Claims (49, 50, 51, 52, 53, 54)
