Abstract
A needle and suture assembly is provided for use with an endoscopic suturing device with a needle holder arm. The needle assembly includes a needle tip and a needle body. The needle tip has a sharp end, a capture groove, a tab groove and a plug portion positioned between the capture groove and the tab groove. The needle body has first and second ends, tip tabs, retainers for removably retaining the needle body relative to the needle holder arm, and a suture opening. The needle tip is fixed relative to the needle body by plastic deformation of the tip tabs into the tab groove. A suture extends into the suture opening of the needle body and is fixed therein.
