A suture device for use in combination with a delivery system including a lumen extending through the delivery system includes a needle usable to carry a suture, a distal shuttle configured to releasably secure the needle, a sleeve disposable over the distal shuttle, the distal shuttle movable relative to the sleeve between a locked position in which the needle is locked to the distal shuttle and an unlocked position in which the needle is releasable from the distal shuttle. The suture device includes a distal assembly including an elongate tool guide movable between a deployment configuration in which the elongate tool guide is substantially parallel with the distal assembly and a working configuration in which the elongate tool guide curves away from the distal assembly.

A surgical suturing system is disclosed. The surgical suturing system comprises a shaft, a firing drive comprising a motor, and an end effector extending distally from the shaft. The end effector comprises a needle driver configured to be actuated by the motor, wherein the needle driver is configured to drive a needle installed within the end effector. The end effector further comprises a needle track configured to guide the needle installed within the end effector through a needle firing stroke, wherein the end effector is configured to accommodate suturing needles having different sizes. The surgical suturing system further comprises a control circuit configured to sense the size of the suturing needle installed within the end effector and adjust the actuation stroke of the motor to accommodate the size of the needle installed within the end effector.

Disclosed embodiments include apparatuses, systems, and methods for guiding a needle to facilitate suturing, such as in surgical anastomosis. In an illustrative embodiment, an apparatus includes at least one guide member configured to extend from a suturing mechanism that is configured to revolve a helically-shaped needle around an axis while the needle is advanced around an object to be sutured. A guide track is configured to be positioned around the object and to guide the suturing mechanism in an articulated path around the object. The guide track defines at least one guide channel configured to receive the guide member, where the at least one guide channel is configured to direct movement of the guide member to cause the suturing mechanism to pivot to realign the axis to be tangential to the curved guide track.

A surgical suturing system is disclosed. The surgical suturing system comprises a firing drive, an end effector, and a needle configured to be driven by said firing drive. The end effector comprises a track defined therein configured to guide the needle through a needle firing stroke. The surgical suturing system further comprises a needle driver configured to be driven by the firing drive and configured to drive the needle through the needle firing stroke.

A laparoscopic suturing device is provided. The suturing device can pass a suturing needle back and forth between jaws of a jaw assembly to suture tissue at a surgical site in a minimally invasive procedure. The jaw assembly can have a pivotable jaw member in each jaw to position the jaw assembly and needle in a low-profile stowed configuration for insertion through a low diameter surgical port. The jaw assembly can be actuated by a handle assembly that provides simultaneous needle passing from a driving jaw to a receiving jaw and latching the needle within the receiving jaw in a single trigger cycle.

An implant manipulator may have a distal end that retains an implant, a proximal end, and an intermediate portion between the ends. The implant manipulator may be a needle for a suture passer, with a suture capture feature at the distal end. The suture capture feature may have first and second members that flex apart to permit entry of the suture into a suture capture hole wherein the suture is retained until released. A suture passer may include one or more needles. The suture passer may also include a pusher; a distal end with a sharp, blade-like extension; or a side-loading distal end.

A surgical suture apparatus for passing a double-ended surgical needle forwards and backwards includes a main body, a first jaw element and a second jaw element, each including a holding device to hold a needle-end of the surgical needle. The first jaw element and second jaw element are movable with respect to each other between a take-over position, where a surgical needle can be passed between the first holding device and the second holding device, and an open position. The surgical apparatus further includes an operating device to operate the first holding device and the second holding device to alternately hold the first needle-end by the first holding device and the second needle-end by the second holding device, where the first jaw element is detachably mounted on the main body.

A loader for a surgical suturing instrument is disclosed. The loader has a head having a protrusion configured to be releasably held by a tissue bite area of a surgical suturing instrument. The loader also has a tube interface. The loader further has one or more ferrule holders. The loader also has one or more ferrules, each corresponding to and held by one of the one or more ferrule holders and coupled to a suture end that leads from a tube releasably held by the tube interface.

A laparoscopic suturing device is provided. The suturing device can pass a suturing needle back and forth between jaws of a jaw assembly to suture tissue at a surgical site in a minimally invasive procedure. The jaw assembly can have a pivotable jaw member in each jaw to position the jaw assembly and needle in a low-profile stowed configuration for insertion through a low diameter surgical port. The jaw assembly can be actuated by a handle assembly that provides simultaneous needle passing from a driving jaw to a receiving jaw and latching the needle within the receiving jaw in a single trigger cycle.

Provided herein is an endoscopic suturing system configured for attachment to, and use with, an endoscope.
