Anastomosis suturing device and method
First Claim
1. A surgical suturing device comprising:
- an elongate body having a lumen, an outer surface, and an axis extending between a proximal end and a distal end;
a handle disposed at the proximal end of the body;
portions of the body defining a lumen having a generally axial portion extending to the proximal end and a transverse portion extending distally from the axial portion and exiting the body through the outer surface of the body;
the transverse portion of the lumen exiting the elongate body at an exit hole at the outer surface of the body and being sized and configured to receive a needle and a suture attached to the needle;
attachment means disposed at the distal end of the elongate body distally of the exit hole; and
means disposed in the axial portion of the lumen and movable through the lumen for deploying the needle and the suture from the lumen.

Abstract
A surgical suturing device comprises an elongate body having an axis extending between a proximal end and a distal end. A lumen of the body has a generally axial portion and a transverse portion which extends laterally and is adapted to receive a needle and associated suture. An elongate deployment member is disposed in the axial portion of the lumen and biased to a proximal position. The deployment member is movable to a distal portion to expel the needle and suture from the lumen through tissue surrounding the device. An associated method for operating the device includes the steps of deploying the needle and suture from the lumen, moving the device distally to expose the empty transverse lumen, and reloading the lumen with a second needle and suture.

1. A surgical suturing device comprising:
-
an elongate body having a lumen, an outer surface, and an axis extending between a proximal end and a distal end; a handle disposed at the proximal end of the body; portions of the body defining a lumen having a generally axial portion extending to the proximal end and a transverse portion extending distally from the axial portion and exiting the body through the outer surface of the body; the transverse portion of the lumen exiting the elongate body at an exit hole at the outer surface of the body and being sized and configured to receive a needle and a suture attached to the needle; attachment means disposed at the distal end of the elongate body distally of the exit hole; and means disposed in the axial portion of the lumen and movable through the lumen for deploying the needle and the suture from the lumen. - View Dependent Claims (2, 3, 4, 5)

6. A method for attaching a first body conduit to a second body conduit, the second conduit being defined by tissue and having a first end and a second end, the method comprising the steps of:
-
providing a suturing device having an elongate shaft with an outer surface, the shaft defining at least one lumen having a generally axial portion at a proximal end of the lumen and a transverse portion extending from the axial portion at a distal end of the lumen, the transverse portion exiting the device through an exit hole at the outer surface of the elongate shaft; loading the lumen with a needle having a sharp tip and a suture attached to the needle; inserting the distal end of the suturing device into the first end of the second conduit and through the second conduit to the second end of the second conduit; deploying the needle from the lumen and through the exit hole into the tissue at the second end of the second conduit, in a direction generally toward the first conduit; and connecting the suture to the first body conduit to attach the first body conduit to the second body conduit. - View Dependent Claims (7, 8, 9, 10)

11. A method of suturing tissue forming a free end of a body conduit, comprising:
-
providing a suturing device having an elongate shaft with an outer surface, the shaft defining at least one lumen having a generally axial portion at a proximal end of the lumen and a transverse portion extending from the axial portion of the lumen toward a distal end of the device and exiting the device through an exit hole at the outer surface of the device, said suturing device further having a traction mechanism in the form of an annular flange extending radially outwardly of the outer surface of the shaft; advancing the suturing device within the body conduit until the traction mechanism is disposed at the free end of the conduit.

12. A method for suturing tissue forming a circumferential free end of a body conduit, comprising the steps of:
-
providing a suturing device having an elongate shaft and portions defining a lumen extending through an exit hole at an outer surface of the shaft; loading a first needle and attached suture into the lumen of the suturing device; inserting the device into a body conduit into an operative site where the tissue of the body conduit covers the exit hole; issuing the first needle and attached suture from the lumen and through the tissue; advancing the device distally to expose the exit hole; reloading the lumen with an additional needle and attached suture; retracting the device proximally to a new operative site where the tissue of the body conduit covers the exit hole; and deploying the second needle from the lumen at the new operative site. - View Dependent Claims (13)

14. A surgical suturing device comprising:
-
an elongate body having a lumen, an outer surface, and an axis extending between a proximal end and a distal end; a handle disposed at the proximal end of the body; portions of the body defining a lumen having a generally axial portion extending to the proximal end and a transverse portion extending distally from the axial portion and exiting the body through the outer surface of the body; the transverse portion of the lumen being sized and configured to receive a needle and a suture attached to the needle; means disposed in the axial portion of the lumen and movable through the lumen for deploying the needle and the suture from the lumen; and a traction mechanism in the form of an annulus extending radially outwardly of the outer surface at the distal end of the body. - View Dependent Claims (15, 16, 17, 18)
