Endoscopic suturing system having external instrument channel

Abstract:

An endoscopic suturing system includes an endoscope, a suturing device, a needle assembly movable through tissue by the suturing device, and first and second devices used in association with the suturing device. The cap assembly includes a rotatable needle arm supporting the needle assembly and actuatable by a proximal handle via a transmission assembly. First and second separate lumen extends outside the endoscope from the cap assembly to a proximal handle to advance instruments therethrough to engage the needle assembly and target the tissue. The cap assembly is retained at an end of the endoscope by a securing arm. The securing arm may be resilient or rotatable. Ancillary clips are also provided about the first and second lumen and transmission assembly to couple them to the endoscope.
