ARTICLE, SYSTEM, AND METHOD FOR SECURING MEDICAL DEVICES TO TREAT OBESITY, GASTRO-ESOPHAGEAL REFLUX DISEASE (GERD) AND IRRITABLE BOWEL SYNDROME (IBS) REVERSIBLY

摘要

A medical staple formed from a nitinol wire, the staple having two elongated arms which extend upwardly and outwardly from a central loop in two opposing generally semicircular courses forming an arc extending upwardly and outwardly and an end second comprising a sharpened endpoint, the endpoint being the arms bendable under resistance, is disclosed. In some embodiments the arms extend upwardly on a parallel course and then outwardly. The material is preferably an alloy with hyperelastic characteristics. The staples are placed in a flexible endoscope and a lumen catheter within the endoscope, using a hook or forceps in the lumen catheter having a distal end in the lumen of the catheter and the staple distal to the forceps in folded configuration with the arms folded inward in the lumen catheter, positioning the distal end of the lumen catheter at a location in the patient's gastrointestinal tract where stapling is desired, moving the forceps distally so as to force the staple forward out of the lumen catheter and cause the end points to pierce the patient' s inner wall of the gastrointestinal tract.
