Surgical sutures having a core extending along a length thereof between a first end and a second end, and a plurality of sets of first and second projections, wherein the first projections extend in a direction of a first end of the suture and the second projections extend in a direction of a second end of the suture. The first projections may be sized and shaped, and positioned relative to the second projections so as to be capable of substantially shielding the second projections when the surgical suture is drawn through tissue by the second end thereof. The first projections may additionally or alternatively be capable of overlapping and substantially covering a distal end of the respective second projections when the suture is drawn through tissue by the second end.

A barbed monofilament and a method for making the same is provided. The barbed monofilament has a substantially triangular primary cross-section defined by a periphery including first, second and third points of said triangle, and further has a plurality of barbs formed therein. Successive barbs are staggered around the periphery of the monofilament, and extend inwardly into the monofilament to a predetermined depth from the first, second and third points respectively.

A barbed suture includes a flexible thread having a core with a leading end, a trailing end, and a central axis. The barbed suture includes a first flexible flap connected to the core, the first flap extending between the leading and trailing ends of the core, and a second flexible flap connected to the core, the second flap extending between the leading and trailing ends of the core. The flexible flaps and the core have an S-shaped profile when viewed in cross-section. The barbed suture includes first and second slots formed in the respective first and second flaps for dividing the flaps into first and second barbs projecting from the core, whereby each slot extends outwardly from the core and rearwardly toward the trailing end of the core.

The present disclosure is directed to a method and system for the repair of ventral hernias. The method includes the steps of providing a needle; providing a barbed suture having a distal end attached to said needle; providing a surgical mesh; rolling said surgical mesh, said barbed suture, and said needle to form a rolled mesh having said needle oriented substantially parallel to a longitudinal axis of said rolled mesh; transferring said rolled mesh into a body cavity via a laparoscopic device; unrolling and laying said surgical mesh under a ventral hernia in an abdominal wall; threading said needle and barbed suture through said surgical mesh and said abdominal wall; and trimming said barbed suture.

Medical devices and methods are provided for a minimally-invasive mastoplasty procedure. In the procedure, barbed sutures are used to accomplish a nipple-lift by deploying the sutures cranially from the nipple-areolar complex to stable anatomical features higher on the chest. Additional barbed sutures may be used to accomplish a breast-lift and/or breast contouring by deploying the sutures caudally from stable anatomical features into the breast tissue.

In one embodiment, a medical device includes an elongate member configured to be inserted into a body. The elongate member has a first end portion and a second end portion opposite the first end portion. The elongate member includes a retaining member extending from the elongate member. The retaining member is configured to anchor the elongate member with respect to bodily tissue. The first end portion of the elongate member includes a coupling portion configured to be coupled to a filament. The second end portion of the elongate member includes a coupling portion configured to be coupled to the filament.

A method of making a barbed suture by varying the blade geometry and/or the movement of the blade when cutting a suture is disclosed. The method can also be accomplished with a cutting device to create a plurality of barbs on the exterior of surgical suture. The barbs produced using the method with the cutting device can be the same or random configurations.

A surgical suture includes an elongated core having a first leg and a second leg, a first set of barbs projecting from the first leg of the core, and a second set of barbs projecting from the second leg of the core. The suture has a stop projecting from the core that is located between the first and second sets of barbs, and a braid surrounding the elongated core and the stop for strengthening the suture. The suture includes a pledget having first and second openings extending therethrough, with the first leg extending through the first pledget opening, the second leg extending through the second pledget opening, and the stop extending between the first and second pledget openings.

A barbed suture includes a flexible thread having a leading end and a trailing end, and a plurality of barbs projecting from the flexible thread. The flexible thread has a plurality of web-like openings formed therein, whereby each of the openings is disposed adjacent one of the barbs. The openings enhance the flexibility of the barbs and provide space for the barbs to collapse inwardly as the leading end of the flexible thread is pulled through a medium such as tissue. When the barbs are collapsed, the diameter of the barbed sections is preferably no greater than the diameter of the non-barbed sections. In one embodiment, a support element interconnects at least one of the barbs and the flexible thread for reinforcing the at least one barb and resisting flexure of the at least one barb toward the leading end of the flexible thread.

A kit and method for supporting a pelvic floor of a person with stress urinary incontinence or other symptoms. The method involves using barbed sutures as part of a sling for supporting the pelvic floor or urethra of a person experiencing stress urinary incontinence or other symptoms. A surgeon implants the sling along with the barbed sutures, using one of several known methods. The barbed sutures may be interwoven with the sling and the supports for the sling, so that once the sling and its supports are placed into the patient, barbs of the sutures will resist movement. The sutures may also be woven into the supports to resist movement.

A suture including a shaft extending longitudinally along a length of the suture, and a plurality of barbs extending outwardly from said shaft. At least one of the barbs is non-symmetrical about a primary plane extending along the longitudinal length of the suture, and bisecting a distal tip of the barb and a center of the shaft.

A suture package configured to retain one or more barbed suture is provided. The suture package includes, a base member having an outer wall and including a suture retaining area, at least one needle retainer positioned adjacent the suture retaining area for receiving at least one suture needle, at least one suture retainer positioned adjacent the suture retaining area for receiving a distal end of at least one suture, a plurality of raised portions formed within the suture retaining area, each of the raised portions including a groove for receiving a portion of at least one suture therein.

A wound closure device having a filamentary element having a proximal end and a distal end, and a stop element coupled thereto and having a leading edge area defined by thickness and a width and having a total surface area. The leading edge area is substantially perpendicular to a longitudinal axis of the filamentary element. The device may have a ratio of the leading edge area to the total surface area that is less than 10%, a ratio of the length to the maximum thickness of the stop element that is at least 4, or a ratio of the length to the width of the stop element is at least 1 for any given thickness.

A suture package for retaining a barbed suture is provided. The suture package includes a suture retaining member including an outer wall and an inner wall. The inner wall is radially spaced from the outer wall and defines a suture retaining area therebetween. The inner wall defines a needle retaining area and includes at least one opening therein to permit reception of at least one suture therethrough. The outer wall includes a plurality of inwardly extending tabs configured to engage a cover. The suture package further includes a cover configured to be received within the outer wall of the suture retaining member and to selectively engage the inwardly extending tabs formed thereon.

A surgical suture includes a plurality of intertwined unbarbed filaments defining a longitudinal axis and a barbed filament including an elongate body and a plurality of barbs disposed along a length thereof. The plurality of barbs extends radially outward from a surface of the elongate body, wherein the barbed filament at least partially intertwines with the plurality of unbarbed filaments.
