Abstract: In accordance with the present invention there is provided a suturing device. The suturing device includes a length of suture that will be delivered to the site of the PFO and placed through the tissue adjacent the opening to close the PFO. As described in greater detail below, the suture is advanced through the tissue surrounding the opening by a pair of needles that penetrate the tissue adjacent to the opening. A knot is then loosely tied with the length of suture and advanced to the site of the PFO. The tails of the suture extending from the knot are then cut and removed. It is also contemplated that a pre-formed or pre-tied knot may be disposed on the device, wherein after deployment of the suture through the tissue adjacent to the PFO and removal of the device a loop of suture having a pre-tied knot will remain, wherein the pre-tied knot may then be tightened to close the PFO. Further still it is contemplated that other means may be utilized to retain the sutures.

Abstract: A surgical suturing device has a body with a “J”-shaped suturing needle attached. One end of a movable arm is pivotably attached to the body so that the other end of the movable arm may swing into and out of engagement with the tip of the suturing needle. The movable arm is engaged by a rod that slides transversely within the body. The moveable arm swings in response to pressure on a thumb nut that moves the rod. Rod movement is resisted by a compression spring within the body. The device allows a surgeon to suture the fascial layer from within a surgical incision. The surgeon avoids unwanted penetration of tissue by pressing the thumb nut to cause the movable arm to engage and cover at least a portion of the needle tip.

Subsequently, the knot placer can be pulled out of the access port (21), and the slit eyelet (16) can release its respective suture end (25a) or (25b) through the slit (19). Another slidable knot (27) can be tied.

Abstract: A suture punch system that is capable of directly passing braided suture through tissue in a simple, one-step process. The system includes three principle components: a malleable needle capable of delivering the suture to the tissue, a handheld instrument for grasping tissue and controlling needle placement, and a force-supplying mechanism to supply the force required for needle placement. Needle deformation begins at the tip of the instrument, which beneficially includes a curved segment. As the distal tip of the needle pierces the tissue, it continues its radial path through the tissue. When the proximal end of the needle exits from the instrument, the needle may be radial in shape and traverses an essentially radial path through the tissue. Non-radial linear or non-linear segments may alternatively be used. In one embodiment, the tissue to be sutured is constrained by pressure applied through closure between an upper, moveable jaw at the distal portion of the instrument, which acts as a fixed jaw.

The jaws are configured to allow for atraumatic grasping of soft tissues. The stationary jaw may include a molded tip that holds and positions opposite ends of a single strand of suture material. The serrated upper jaw is configured to grasp and immobilize the tissue to be sutured. Hooked needles are movably positioned to pierce the grasped and immobilized tissues, and to engage and retrieve the opposite ends of the single strand of suture material. The handle is released to open the moveable jaw, whereupon the instrument may be withdrawn, trailing the suture, and leaving a mattress stitch in the grasped tissue.

The scale factor is adjustable so that the surgeon can control the resolution of the end effector movement. The movement of the end effector can be controlled by an input button, so that the end effector only moves when the button is depressed by the surgeon.
