Devices and methods for performing procedures on a breast
View Patent ↗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.
1. 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 cuffing 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;
forming at least a part of a second incision in the patient's breast without fully removing the cutting element from the patient's breast, the second incision being different from the first incision, the second incision being formed by expanding the cutting element outwardly from the cut tissue until the cutting element breaches a surface of the breast, and
removing the breast tissue through the second incision.
2. The method of claim 1 , 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.
3. The method of claim 1 , 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.
4. The method of claim 1 , wherein:
the forming step is also carried out with the second incision being partly formed by the tip of the tissue cutting device piercing through the skin at the second incision so that the tissue cutting device penetrates the first and second incisions.
5. The method of claim 1 , 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.
6. The method of claim 5 , 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.
7. 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 cuffing 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
making a second incision that is different from the first incision by expanding the cutting element outwardly from the cut tissue until the cutting element breaches a surface of the breast;
removing the tissue collection element through the second incision using a removal device that extends through the second incision and that is coupled to the tissue collection element.
8. The method of claim 7 , 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.
9. The method of claim 7 , 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.
