Abstract
An endoscopic suturing includes a suturing device having a curved needle to suture tissue. The endoscopic suturing device also includes a driving means to maneuver the curved needle. The curved needle and the driving means are placed at a distal end of the endoscopic suturing device. The endoscopic suturing device also includes a flexible endoscope connected to the suturing device.
Claims17
