Abstract
Sutures can be placed in difficult to access areas of the human body with devices, and related methods, utilizing a suture carrier with a sharpened tip and a notch for holding a formed suture tip. The devices and methods can be used in conjunction with both endosurgical and traditional open surgery
Claims29
A suturing instrument comprising:
- an elongate body member;
- a suture deployment system disposed at a distal portion of the elongate body member, the suture deployment system comprising a suture carrier including a sharpened distal end for tissue penetration and a notch for holding a formed suture tip;
- and
- a catch disposed on the elongate body member to receive and retain the formed suture tip.

A suturing instrument comprising:
- a body member defining a suture exit port and a suture carrier channel;
- and
- a suture carrier including a sharpened distal end for tissue penetration and a notch for holding a formed suture tip, wherein the suture carrier is movably positioned in the suture carrier channel to move between a retracted position within an interior region of the body member and a deployed position exterior to the body member, the suture carrier being configured within the suture carrier channel such that the suture carrier exits the interior region of the body member through the suture exit port.
A suturing instrument comprising:
- an elongate body member having a longitudinal axis;
- a distal tip suture deployment assembly joined with a distal end of the elongate body member such that the distal tip suture deployment assembly is free to rotate axially about the longitudinal axis of the elongate body member, the distal tip suture deployment assembly comprising
- a suture exit port formed in the distal tip suture deployment assembly,
- a curved suture carrier channel formed in the distal tip suture deployment assembly,
- a curved suture carrier movably positioned in the curved suture carrier channel, and
- a suture with a formed tip coupled to the suture carrier;
- and
- a deployment controller including a distal end, the deployment controller extending substantially along the longitudinal axis of the elongate body member to a distal end of the elongate body member where the distal end of the deployment controller is coupled to the distal tip suture deployment assembly and moves the curved suture carrier through the curved suture carrier channel as the deployment controller moves between a retracted position and a deployed position.

A method for placing a suture in tissue comprising the steps of:
- inserting a suturing instrument enclosing a suture carrier including a sharpened distal end for tissue penetration and a notch for holding a formed suture tip, wherein the suture carrier is movably positioned within a suture carrier channel adjacent the tissue to be sutured;
- deploying the suture carrier out of the suturing instrument through an exit port such that the suture carrier exits an interior region of the suturing instrument through the exit port along a path approximately tangential to an outer surface of the suturing instrument surrounding the exit port;
- and
- capturing a suture carried by the suture carrier in a catch that receives and retains the formed suture tip.

A suturing instrument comprising:
- a body member defining a suture exit port and a carrier channel;
- a carrier movably positioned in the carrier channel between a retracted position within an interior region of the body member and a deployed position exterior to the body member such that the carrier exits the interior region of the body member through the exit port;
- and
- a surgical needle permanently fixed on a distal end of the carrier.
