Abstract

A guide element is used to guide a cutting device when removing breast tissue. The cutting device may have a tissue collection element for collecting tissue. The tissue collection element may be detachable so that the collection element may be removed independent from the cutting device.

Claims

1. A method of removing tissue from a breast, comprising the steps of:

providing a tissue cutting device having a shaft and an elongate cutting element coupled to the shaft and movable from a retracted position to an expanded position, the cutting element being an elongate element which bows outward in the expanded position;

advancing the tissue cutting device adjacent to tissue to be removed and without penetrating a tissue area that is to be removed;

expanding the cutting element toward the expanded position;

moving the cutting element through the breast tissue to cut the breast tissue, the cutting element being moved around the tissue volume of interest to create a peripheral margin around the tissue area;

2. The method of claim 1, wherein:

the providing step is carried out with the cutting element being an RF energized thin wire.

3. The method of claim 1, wherein:

the removing step is carried out with the tissue volume being removed with vacuum device.

4. A method of removing breast tissue, comprising the steps of:

providing a tissue cutting device having a shaft and a cutting element, the cutting element being movable from a collapsed position to an expanded position;

introducing the tissue cutting device into the patient'"'"'s breast through a first incision with the cutting element in the collapsed position;

expanding the cutting element;

moving the cutting element through breast tissue to cut around the tissue to be removed; and

removing the breast tissue through a second incision different from the first incision.

5. The method of claim 4, wherein:

the providing step is carried out with the tissue removing device having a tissue collection element; and

the removing step being carried out with the tissue being carried in the tissue collection element.

6. The method of claim 4, wherein:

the providing step is carried out with the cutting element being an RF cutting element, the RF cutting element bowing outward when moving from the first position to the second position.

7. The method of claim 4, further comprising the step of:

the forming step is carried out with the second incision being at least partially formed by the tissue cutting device.

8. The method of claim 4, further comprising the step of:

forming at least part of the second incision with the cutting element.

9. The method of claim 8, wherein:

the forming step is carried out with the second incision being formed by the tip of the tissue cutting device piercing through the skin at the second incision so that the tissue cutting device is penetrates the first and second incisions.

10. The method of claim 8, wherein:

the forming step is carried out with the second incision being created by the cutting element of the tissue cutting device.

11. The method of claim 4, further comprising the step of:

encapsulating the tissue to be removed in a tissue collection element; and

the removing step is carried out with the tissue contained in the tissue collection element.

12. The method of claim 11, further comprising the step of:

releasing the tissue collection element; and

the removing step being carried out with the tissue contained within the tissue collection element when removed through the second incision.

13. A method of removing breast tissue, comprising the steps of:

providing a tissue cutting device having a shaft, a tissue collection element and a cutting element, the cutting element being movable from a collapsed position to an expanded position;

introducing the tissue cutting device into the patient'"'"'s breast through a first incision with the cutting element in the collapsed position;

expanding the cutting element;

moving the cutting element through breast tissue to cut around the tissue to be removed;

positioning the tissue cut by the cutting element into the tissue collection element; and

removing the tissue collection element through a second incision different from the first incision.

14. The method of claim 13, wherein:

the removing step is carried out with a removal device extending through the second incision, the removal step including the step of coupling the removal device to the tissue collection element.

15. The method of claim 14, wherein:

the removing step is carried out with the removal device has a distal end movable between a collapsed position and an expanded position, the expanded position being flared outwardly.

16. The method of claim 14, wherein:

the removing step is carried out with the removal device having a suction opening coupled to a vacuum source, the removal device adhering to the tissue collection element with the suction opening.
