A recently filed patent (Publication Number: US20230181183A1) describes a needle and suture assembly for use with a suturing device. The assembly includes a needle assembly and a suture. The needle assembly consists of a needle tip with a sharp end, a tubular needle body with a lumen, and tab retainers that can be deformed inward to retain the needle body on the needle holder arm of the suturing device. The needle body also has a suture opening located between the first end and the retainers. The suture is fixed within the suture opening of the needle body.

The patent also claims that the needle tip is a separate element from the needle body and is fixed relative to it. The needle tip defines tab grooves, and the needle body has tip tabs that are plastically deformed into the tab grooves to secure the needle tip to the needle body. The tip tabs are provided adjacent to the first end of the needle body.

Additionally, the patent describes a capture groove on the needle assembly that can be engaged by a tool for removing the needle assembly from the needle holder arm. The capture groove is a circumferential groove located on the tubular body adjacent to the needle tip.

The patent also includes claims for an endoscopic suturing assembly, which includes a suture needle holder arm with a circumferential groove at its free end. The assembly further comprises a suture needle with a needle tip, a tubular needle body, and elastically deformable tab retainers. The tubular needle body is sized to receive a portion of the free end of the needle holder arm with the circumferential groove. The tab retainers engage the free end at the circumferential groove to mount the suture needle on the holder arm. Applying a sufficient relative force coaxial with the axis of the needle tip and away from the tip causes elastic deformation of the tab retainers, releasing the suture needle from the holder arm.

Overall, this patent describes a needle and suture assembly and an endoscopic suturing assembly that provide improved functionality and ease of use in suturing procedures. The design allows for secure attachment and release of the needle assembly from the suturing device, as well as fixed placement of the suture within the needle body. The inclusion of a capture groove facilitates easy removal of the needle assembly, enhancing the efficiency of the suturing process.
