1. A method of positioning a needle in a patient'"'"'s breast for a medical procedure, comprising the steps of:
- providing a needle having a distal portion, a proximal portion and at least one radially movable indicator at the proximal portion for indicating a radial angular orientation when viewed along a longitudinal axis of the needle;
positioning the distal portion in the 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.

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.

10. A needle for introduction into a patient'"'"'s breast, comprising:
-
an elongate shaft having a longitudinal axis, a distal portion configured to be positioned within the patient'"'"'s breast and a proximal portion configured to remain outside the patient'"'"'s breast; and a first indicator at the proximal portion for indicating an angular orientation when viewed along the longitudinal axis of the shaft, the first indicator being radially movable by a user to a selected radial angular orientation relative to the longitudinal axis of the shaft. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A method of excising breast tissue, comprising the steps of:
-
providing a guide element having a distal portion, a proximal portion and a cutting device, the guide element having at least one radially movable indicator at the proximal portion 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 the shaft; introducing the distal portion of the guide element into a patient'"'"'s breast with the proximal portion remaining outside the 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 (18, 19, 20, 21, 22, 23)

24. A system for removing breast tissue, comprising:
-
a guide element, the guide element having a distal portion configured to be positioned within a patient'"'"'s breast, a proximal portion configured to remain outside the patient'"'"'s breast and a first radially movable indicator at the proximal portion for indicating an angular orientation with respect to a longitudinal axis of the guide element; and a cutting device coupled to the distal portion, 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 (25, 26, 27, 28, 29)

30. 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 at a proximal end thereof 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 less than 180 degrees relative to the guide element so that the cutting element severs breast tissue; and removing the breast tissue which has been severed by the cutting element. - View Dependent Claims (31, 32, 33, 34, 35)
