Anastomosis device approximating structure configurations
View Patent ↗A surgical tool including 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 at the proximal end of the elongated body for independently deploying and retracting each of the first and second sets of tissue approximating structures, and a drainage lumen extending from a drainage aperture at the distal end of the elongated body to the proximal end. The tool further includes a main balloon adjacent to the distal end of the elongated body, and a second balloon spaced from the main balloon toward the proximal end of the elongated body, wherein the second balloon has an expanded condition in which it diverts one of the set of tissue approximating structures away from the main balloon.
1. A surgical tool comprising:
an elongated body having a proximal end, a distal end, and an outer surface extending along its length between the proximal and distal ends;
first and second sets of tissue approximating structures, wherein each tissue approximating structure comprises a radially deployed position and a radially retracted position relative to the outer surface of the elongated body;
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;
a drainage lumen extending from a drainage aperture at the distal end of the elongated body to the proximal end; and
a main balloon adjacent to the distal end of the elongated body;
wherein the first set of tissue approximating structures has a different configuration than the second set of tissue approximating structures, and wherein the second set of tissue approximating structures includes at least one extension that is pivotable toward and away from the outer surface of the elongated body.
2. The surgical tool of claim 1 , wherein a distance between the first set of tissue approximating structures and the main balloon is greater than a distance between the second set of tissue approximating structures and the main balloon.
3. The surgical tool of claim 1 , wherein a distance between the first set of tissue approximating structures and the main balloon is less than a distance between the second set of tissue approximating structures and the main balloon.
4. The surgical tool of claim 1 , wherein the first set of tissue approximating structures comprises a plurality of tines.
5. The surgical tool of claim 1 , wherein each of the tissue approximating structures comprises a distal end that is radially moveable relative to the outer surface of the elongated body such that the distal end of each of the tissue approximating structures is further from the outer surface of the elongated body when in the radially deployed position than when in the radially retracted position.
6. A surgical tool comprising:
an elongated body comprising a proximal end, a distal end, and at least one recessed area;
first and second sets of tissue approximating structures having deployed and retracted positions relative to the elongated body;
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;
a drainage lumen extending from a drainage aperture at the distal end of the elongated body to the proximal end; and
a main balloon adjacent to the distal end of the elongated body;
wherein the first set of tissue approximating structures has a different configuration than the second set of tissue approximating structures, wherein the second set of tissue approximating structures includes at least one extension that is pivotable toward and away from the elongated body, and wherein each of the at least one extensions is pivotable into and out of one of the recessed areas.
7. The surgical tool of claim 6 , wherein each of the at least one recessed areas comprises a slot in the elongated body.
