Linear suturing apparatus and methods
First Claim
1. A suturing device for use endoscopically, comprising:
- a first jaw member;
a second jaw member, said first and second jaw members being disposed at a distal end of said suturing device;
an actuator disposed at a proximal end of the suturing device, for actuating the first and second jaw members between a closed orientation, wherein the first and second jaw members are disposed in close proximity to one another, and an open orientation, wherein said first and second jaw members are substantially spaced from one another;
a hollow barrel disposed between said actuator and said first and second jaw members;
a linking member disposed within said hollow barrel, connecting said actuator with said first jaw member;
at least one needle disposed at the distal end of said suturing device, said at least one needle being movable between a retracted position and an extended position for passage through tissue grasped between said first and second jaw members; and
a needle carriage on which said at least one needle is disposed, said needle carriage being axially movable between distal and proximal positions at said distal end of said suturing device.

Abstract
A suturing instrument and methods for placing mattress stitches in soft tissues comprises an elongate shaft with a stationary jaw and a movable jaw disposed at a distal end thereof. The movable jaw is coupled to a handle grip at the proximal end of the shaft and is configured to manipulate the movable jaw into open and closed positions respective to the stationary jaw. The jaws are configured to permit atraumatic grasping of soft tissues to be sutured. The stationary jaw is comprised of a serrated face, incorporating apertures through which needles may be driven distally into and through the grasped tissue and into needle capture cans attached to opposing ends of a single strand of suture material. The serrated upper jaw is configured with capture means adapted to accept and capture the needles and suture. The handle is released to open the movable jaw, after which the instrument may be withdrawn, trailing the suture, and leaving a mattress stitch in the grasped tissue.

14. A suturing device for use endoscopically, comprising:
-
a first jaw member;
a second jaw member, said first and second jaw members being disposed at a distal end of said suturing device and being movable between a closed orientation, wherein the first and second jaw members are in close proximity to one another, and an open orientation, wherein the first and second jaw members are substantially spaced from one another;
a needle carriage which is axially movable between distal and proximal positions at said distal end of said suturing device; and
at least one needle disposed on said needle carriage, the axial movement of said needle carriage functioning to move said at least one needle between a retracted position and an extended position for passage through tissue grasped between said first and second jaw members. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22)
