Anastomosis device configurations and methods
First Claim
1. A method of performing anastomosis, the method comprising:
- inserting a portion of an anastomosis device into a body lumen of a patient, the anastomosis device comprising;
an elongated body having a proximal end and a distal end;
first and second tissue approximating structures having deployed and retracted positions relative to the elongated body; and
an actuating mechanism at the proximal end of the elongated body for independently deploying and retracting each of the first and second sets of tissue approximating structures;
deploying the first and second tissue approximating structures into severed tissue of the patient by activating the actuating mechanism;
maintaining the first and second tissue approximating structures within the severed tissue for a period of time;
using an extraction tool to disengage at least one of the first and second tissue approximating structures from the severed tissue;
wherein the extraction tool comprises a tubular structure that has a diameter that is slightly larger than a diameter of the elongated body of the anastomosis device.

Abstract
A surgical tool which comprises an elongated body having a proximal end and a distal end, first and second sets of tissue approximating structures having deployed and retracted positions relative to the elongated body, an actuating mechanism extending from the proximal end of the elongated body for independently deploying and retracting each of the first and second sets of tissue approximating structures, a drainage lumen extending from a drainage aperture at the distal end of the elongated body to the proximal end, a main balloon adjacent to the distal end of the elongated body, and a strap connector extending from the elongated body that is connectable with a stabilization strap.
