Abstract

A method for removing a tissue lesion where an anchor is established with the lesion. A channel is created in the tissue leading to the anchored lesion. A tissue core is created which includes the lesion. The tissue core is ligated, amputated and removed from the channel.

Claims (18)

1. A method for removing a tissue lesion comprising blood vessels and airways, the method comprising:

inserting an anchor through a center portion of the tissue lesion such that a distal end portion of the anchor is positioned at a bottom portion of the tissue lesion;

creating a channel in tissue leading to the tissue lesion;

creating a tissue core including the tissue lesion;

ligating the tissue core at a ligation point downstream from the tissue lesion;

amputating the tissue core form the tissue between the ligation point and the tissue lesion;

providing a removal device over the anchor such that the tissue lesion is positioned within an inner diameter of the removal device; and

removing the tissue core from the channel, the tissue core including sealed vessels and tissue.

2. The method of claim 1 , further comprising inserting a sleeve in the channel prior to or after removing the tissue core.

3. The method of claim 2 , further comprising anchoring the sleeve to the tissue.

4. The method of claim 2 , further comprising delivering localized treatment through the sleeve.

5. The method of claim 1 , wherein creating the tissue core includes cauterizing and cutting the tissue.

6. The method of claim 5 , wherein ligating the tissue core includes cauterizing the tissue at the ligation point.

7. The method of claim 5 , wherein ligating the tissue core includes suturing the tissue at the ligation point.

8. The method of claim 1 , wherein amputating the tissue core includes slicing the tissue core.

9. The method of claim 8 , wherein amputating the tissue core includes slicing the tissue core with a snare.

10. The method of claim 8 , wherein amputating the tissue core includes slicing the tissue core with an energized wire.

11. The method of claim 1 , wherein creating the tissue core includes first sealing blood vessels then slicing the tissue to form the tissue core.
