Sketch of endoscopic suturing device
The invention is a novel endoscopic suturing device including a unique needle design. The design overcomes major limitations of related devices such as the inability to place multiple sutures, the inability to tie a knot without the help of a separate knot-tying device, the inability to tie a knot inside the patient, and the relatively large size which prevents through-the-endoscope placement. This technology is unlike currently available suturing devices because it can pass through a working channel (3-6 mm in diameter) of a flexible endoscope.
Application & Market Utility
The invention targets incisionless surgery using flexible endoscopes. A flexible endoscope has several channels including light transmission, image transmission, air and water, and “working channels” through which instruments are inserted. Natural orifice transluminal endoscopic surgery (NOTES) can replace laparoscopic instruments. In one procedure, the endoscope is passed through the esophagus and an incision is made in the stomach to obtain access to the abdominal cavity, thus avoiding an external wound and a deeper dissection.
