A suturing device includes an elongated body having an outer wall defining an interior space of the body, a shaft located in the interior space, and a needle mounted on a distal end of the shaft. The needle has a distal section transverse to a longitudinal axis of the shaft. The distal section of the needle terminates in a first jaw and a second jaw forming a forceps defining a piercing tip. The first jaw and second jaw have a grasping position wherein the first jaw and second jaw grasp a suturing material, and a release position wherein the first jaw and second jaw release the suturing material. After grasping the suturing material with the needle, the shaft rotates the needle to advance the needle and suturing material through tissue and mesh placed on the tissue. Spaced apart portions of the suturing material are then fused to create a suture.

Disclosed is a device that uses suture to close various layers of tissue quickly and precisely. The device and methods enhance the efficiency, consistency and cost-effectiveness of traditional hand-suturing without compromising cosmetic or wound healing outcomes. Adjustable instruments on either side of the device are applied to opposing sides of the desired layer of tissue to approximate the edges of the tissue to be closed. The user may control the delivery of a single stitch or a series of stitches at an adjustable interval to the desired layer of tissue. An instrument may perform the stitch or series of stitches as the operator guides the device along the tissue opening. Once the device has delivered the appropriate stitch(es), the user may remove excess suture material and release the tissue from the instruments on either side of the incision and the process may be repeated as necessary to close a wound.

Device and method embodiments discussed herein are directed to mechanical closure of an access passage in a tissue layer adjacent to an access hole in a vessel such as an artery or vein of a patient. Some of these embodiments may also be applicable to direct closure of a vessel wall in some instances.

The present application provides a suture structure for medical surgery and a process for making the same. The suture structure includes: a thread head core, a winding yarn and a suture connection yarn. In particular, the thread head core is formed by bundling a plurality of thread core yarns; a connection section is provided at a first end of the suture connection yarn; the connection section is attached to the thread head core along a length direction of the thread head core; a second end of the suture connection yarn extends out from the thread head core at the middle of the thread head core; the thread head core and the connection section are wound along the length direction of the thread head core to form a thread rod; and the core yarn, the winding yarn and the suture connection yarn are made of thermoplastic resin fibers.

The present invention includes, in one embodiment, a method of forming a suture having various cross-sectional shapes, the method including the steps of braiding the suture such that the suture has a first cross-sectional shape along a length; holding a first end of the suture and holding the suture at a second position at a location in between the first end and a second end such that a first portion of the suture is defined between the first end and the second position; manipulating the first end relative to the second position to alter the first portion of the suture into an altered cross-sectional shape different from the first cross-sectional shape; and releasing the first end and the second position, wherein the step of manipulating is performed such that, upon release, the first portion maintains its manipulated shape.

Described herein are systems and methods for securing sutures that obviate the need for tying knots. A device can be applied to adjacent suture portions that heats the suture portions and causes the suture portions to fuse together, effectively securing the suture portions together without a knot. The device can include a handle, an outer shaft coupled to the handle, an inner shaft movable proximally and distally within the outer shaft; a suture holder at the distal end portion of the outer shaft, and an electrical heating element positioned within the outer shaft. Actuation of the device causes the inner shaft and the heating element to move distally relative to the outer shaft and the suture holder, such that the heating element moves into the proximity of the suture holder to fuse together sutures held by the suture holder.

A suture and a suture retainer are positioned relative to body tissue. Ultrasonic vibratory energy is utilized to heat the suture retainer and effect a bonding of portions of the suture retainer to each other and/or to the suture. Portions of the body tissue may be pressed into linear apposition with each other and held in place by cooperation between the suture and the suture retainer. The suture retainer may include one or more portions between which the suture extends. The suture retainer may include sections which have surface areas which are bonded together. If desired, the suture may be wrapped around one of the sections of the suture retainer. The suture retainer may be formed with a recess in which the suture is received. If desired, the suture retainer may be omitted and the sections of the suture bonded to each other.

An active anvil assembly for use in forming a looped suture is provided. The active anvil assembly includes an anvil member, a first sensor operably connected to the anvil member, and a control assembly. The first sensor is configured for measuring at least one of force, torque, and distance feedback. Also provided are systems and methods for forming a looped suture including an active anvil assembly.

A system including a bone punch tool and a needle guide. The bone punch tool can include a support arm having a support arm proximal portion and a support arm distal portion, a pivot arm having a pivot arm proximal portion and a pivot arm distal portion, and an arcuate punch configured to punch through bone. The pivot arm distal portion can be pivotably coupled to the support arm distal portion, such that the pivot arm proximal portion is configured to be moved away from the support arm proximal portion to extend the arcuate punch into a punch position to punch an arcuate hole through bone. The needle guide can be configured to guide a needle through the arcuate hole.

The present invention includes, in one embodiment, a method of forming a suture having various cross-sectional shapes, the method including the steps of braiding the suture such that the suture has a first cross-sectional shape along a length; holding a first end of the suture and holding the suture at a second position at a location in between the first end and a second end such that a first portion of the suture is defined between the first end and the second position; manipulating the first end relative to the second position to alter the first portion of the suture into an altered cross-sectional shape different from the first cross-sectional shape; and releasing the first end and the second position, wherein the step of manipulating is performed such that, upon release, the first portion maintains its manipulated shape.
