In one embodiment, the suturing system includes a cap assembly arranged at the distal end portion of an endoscope 12 or guide member, the cap assembly including a rotatable needle holder. The needle holder is actuated through a transmission element extending outside the endoscope 12 or guide member. A needle capture device may be inserted into a channel of the endoscope or guide member in order to capture a needle held in the needle holder when the needle holder is rotated so that the needle punctures tissue. |
