A surgical suturing device (10) having an axis extending between a proximal end and a distal end is operable to move a suture (32) through body tissue (34). A handle assembly (110) is coupled to an elongated shaft (14) having a hollow configuration. An actuating rod (16) is disposed to extend between the handle assembly (110) and the shaft (14). A thumb actuation assembly is coupled to a proximal end of the actuating rod (16) for moving the rod both axially and rotationally. A needle assembly (2) at the distal end of the actuating rod (16) is movable with the actuating rod (16) between an extended state and a retracted state and at various angular orientations.

A medical instrument, such as a surgical device for manipulating and placing a tissue suture and methods of using the same is disclosed. The device comprises a handle, a hollow shaft removably coupled to the handle assembly and a stylet extending within the hollow shaft and longitudinally slideable therein. Preferably, the stylet is not rotationally moveable relative to the shaft. The stylet may be moved between a first position wherein a grasping member formed on the stylet is retracted into a distal end portion of the shaft and a second position wherein the grasping member extends distally beyond the distal end portion of the shaft. Distal movement of an actuation member on the handle correspondingly moves the stylet to the extended position and movement of the actuation member to a proximal position on the handle correspondingly moves the stylet to the retracted position. Lateral movement of the actuation member on the handle does not impart rotational movement of the stylet relative to the shaft.

A bi-directional medical suturing device includes a first needle; a second needle being disposed distal to the first needle; a first thread control member including a first holding portion being movable between a position where the first holding portion prevents a movement of the first needle and a position where the first holding portion does not prevent the movement of the first needle; and a second thread control member including a second holding portion being located the first holding portion, the second holding portion being movable between a position where the second holding portion prevents a movement of the second needle and a position where the second holding portion does not prevent the movement of the second needle.

A knot for suturing includes a temporary knot for suturing a wound, in which the temporary knot has a first loop extending form a start part and wound clockwise, a ring part extending from the first loop and formed at different position from the first loop, a second loop extending from the ring part and wound counterclockwise at the same position as the first loop, and a spare part extending from the second loop to be pulled by a suturing needle. A suturing device includes a suturing needle formed in a hook shape at a front end of a suturing body formed in a plate shape to pierce a wound and a knot supply unit disposed on the suturing body and holding and supplying knots for suturing toward the suturing needle so that the suturing needle stitches the wound.

Described herein is a simplified placement system and method for a tissue graft anchor by which a surgeon may introduce one or more sutures into a hole in a boney tissue, apply tension to the sutures to advance a soft tissue graft to a desired location, and then advance the anchor into the bone while maintaining suture tension and without introducing spin to the suture.

This invention generally relates to devices and methods that allow an operator to deliver a suture and an implant coupled to the suture into the body of a patient without the need for direct-vision of the operator. In one aspect, a medical device includes a receiving arm that releasably holds an implant or suture in place for capture and a clamping arm that includes a needle deployment mechanism for advancing a needle directly to the implant for capture and for retracting the needle with the implant attached to deliver the implant into the desired location. The receiving arm includes a cavity with inner walls that are angled to direct the needle through the opening after the advancing needle pierces and goes through tissue of the patient. The angled walls facilitate movement of the needle into a position within the cavity where the implant gets engaged with the needle.

The present invention provides a circular bone tunneling device, comprising: a hollow elongate body comprising a hollow elongate body head, said hollow elongate body head defining a rigid circular arc, comprising a surgical needle; an extendable and retractable support element, reconfigurable from an extended configuration to a retracted configuration; said support element, in said extended configuration, adapted to be located along said path formed by said rigid circular arc; said support element and said hollow elongate body head are adapted to grasp said bone from at least two points along the circumference of said bone; a stabilizing element.

A tool to fasten tissue or to fasten a prosthetic to tissue includes a gripper to hold one or more tissue portions, a needle, an actuator to drive the needle, a fastener cartridge to store one or more tissue fasteners, a holder cartridge to store one or more holders, and a holder applier to secure one of the holders on one of the fasteners. The actuator drives the needle and the needle pulls a first fastener from the fastener cartridge. The actuator drives the needle through the one or more tissue portions held by the gripper to form a hole in the tissue portions. The needle pulls a leading portion of the first fastener through the hole without a trailing portion of the first fastener being pulled through the hole. The holder applier secures a first holder from the holder cartridge onto the leading portion of the first fastener.

A suturing device is provided. The suturing device may include at least one suturing needle, a drive mechanism and an impulse mechanism. The drive mechanism may be operatively coupled to the suturing needle and configured to advance the suturing needle from a retracted position to an extended position during engagement, and retract the suturing needle from the extended position to the retracted position during disengagement. The impulse mechanism may be operatively coupled to the drive mechanism and configured to accumulate energy during engagement of the suturing needle, and instantaneously release the accumulated energy through the drive mechanism during disengagement.

Apparatus and methods are provided for treating a tissue opening, for example a trocar opening used in a minimally invasive surgical procedure. In a tissue closure device, a finger guard or shield can be used, handle or holding area or areas can be used, and positioning indicators can be used. A resiliently flexible target material can also be used for reliably holding a suture during the procedure. The resiliently flexible target material may be included as part of a removable mating component for use with a movable wing. Introducers can be used having a suture holder, an alignment indicator and insertion limits.
