The present invention provides a suturing device to minimize interference and obstructions during intricate surgeries. The curled suture device is significantly shorter than traditional suturing kits by featuring a needle attached to a specially manufactured thread incorporating a stopping mechanism preceding an angular, semi-rigid portion of thread followed by a curled portion of thread arranged in a corkscrew configuration. The stopping mechanism halts the movement of the thread as the needle and thread intermediate the needle and stopping mechanism is pulled through the suture point, securing the remainder of the thread for access. The semi-rigid portion of thread is thereby utilized in conjunction with its curled portion of thread, allowing for the user's unabated access to the corkscrew configuration to form a ready-made knot, minimizing interference and obstruction during surgery. The thread may be manufactured to form an additional semi-rigid and curled portions of thread upon creation of a knot.

A suture includes an outer sheath with color marks and a background visually distinguishable from the color marks. Each color mark has exposed portions of at least two colored yarns of first and second different colors. The background includes exposed portions of background yarns of a background color. The background yarns and the colored yarns are braided to each other. The first and second colors are different from the background color. The color marks are arranged in at least one row along a longitudinal direction of the suture. Each color mark is longitudinally shifted with respect to a subsequent color mark in a same row by a first shift, and the exposed portions of the colored yarns of each color mark are substantially parallel to each other and arranged in a sequence along the longitudinal direction of the suture.

The present disclosure describes an implantable channel guide configured to identify and/or a channel created in a patient via an endoscopic navigation procedure. The channel guide includes an elongate body having at least one snare on one end portion thereof and at least one anchor member on a second opposite end portion thereof.

Disclosed is a suturing needle having a thread attachment portion and a ramp portion comprising a tapered portion extending from a proximal end of the needle to cover at least a portion of a suture thread swaged in the thread attachment portion. The tapered portion of the ramp portion provides a smooth transition from a diameter of the suture thread to a diameter of the needle body. The tapered transition portion allows for engaging the suture needle on rollers of a rotational needle driver in one smooth motion. The suturing needle includes a hollow flexible extension component having a distal end and a proximal end, the distal end connected to the proximal end of the thread attachment component, and the proximal end attached to the distal end of the tapered extension ramp portion. The suturing needle can include a combination of flexible and non-flexible sections and/or a combination of straight and curved sections.

A medical device includes a surgical needle attached to a hollow tubular suture. The suture is constructed of macroporous hollow tubular wall that facilitates and allows tissue integration into the suture core subsequent to introduction to the body, thereby preventing suture pull-through and improving biocompatibility.

A suture device is utilized in forming a purse string suture during, e.g., laparoscopic end to end anastomosis procedure, to effect joining of two opposing intestinal sections. The suture device is utilized in other procedures such as, e.g., transanal total mesorectal excision (TaTME) for removal of low rectal and ultra-low rectal tumors and preservation of anal sphincters to avoid permanent stomas. In particular, the suture device is utilized in forming surgical stitches used to close an internal anal structure or to narrow a passage for performing further transanal dissection to create total mesorectal excision.

A six-dimensional barbed surgical thread that includes a central core and six first barbs. The central core has a circumference, a proximal end and a distal end that is opposite the proximal end. The six first barbs are positioned around the circumference of the central core so that the first barbs are radially adjacent to each other and obliquely extend from the central core.

Disclosed is a joining element, especially a suture material for surgical use. The joining element is composed of a core having a length that extends along a longitudinal direction, the core including a polymer material and an osmotically active substance distributed within the polymer material, wherein the core has a volume capable of swelling along a transverse direction that is perpendicular to the longitudinal direction upon exposure to a fluid; and, a diffusion-controlling extendable membrane that surrounds at least a portion of the length of the core, wherein the membrane is configured to regulate hydration of the core by the fluid, and is further configured to expand along the transverse direction in response to swelling of the core.

A method and apparatus for coupling a soft tissue implant into a locking cavity formed within a bone is disclosed. The apparatus includes a member to pull the soft tissue implant into a femoral tunnel. The member includes a suture having first and second ends which are passed through first and second openings associated with the longitudinal passage to form a pair of loops. Portions of the suture lay parallel to each other within the suture. Application of tension onto the suture construction causes retraction of the soft tissue implant into the femoral tunnel.

According to an aspect of the present disclosure, an end effector for use with a surgical device is provided. The end effector includes a drive assembly, a driver, a needle assembly and a biasing element. The driver is disposed in mechanical cooperation with the drive assembly. Rotation of the drive assembly in a first direction causes distal translation of the driver with respect to the drive assembly. The needle assembly is disposed in mechanical cooperation with the driver. Distal translation of the driver causes a corresponding distal translation of the needle assembly. The biasing element is disposed in mechanical cooperation with the needle assembly and is configured to bias the needle assembly proximally.
