1. After Surgery At Follow Up Before Surgery You may have blood drawn diagnostic procedures and other tests before your scheduled surgery date Ask your doctor what tests they will require before implantation of your EndoStim IPG and lead You will also meet with an anesthesiologist or surgeon prior to surgery Your doctor may prescribe antibiotic treatment to protect against any infection that may occur after the procedure Surgery The EndoStim IPG and lead will be implanted using general 6 EndoStim Lower Esophageal Sphincter Stimulation Therapy anesthesia An anesthesiologist will monitor you and keep you asleep during the procedure The doctor implants the IPG and leads in your abdominal area The IPG goes inside a pocket that the surgeon creates just under your skin The choice of the pocket site may depend upon how your body is shaped and whether or not you have had any previous abdominal surgery Most often the surgeon performs laparoscopic surgery to implant the IPG and lead Laparoscopic surgery is minimally invasive surgery which means you may have four small incisions on your abdomen instead of a larger one The surgeon inserts surgical instruments and the laparoscope through the incisions A laparoscope is a flexible tube like instrument that connects to a camera so the surgeon can view the inside of the abdomen on a TV monitor In some cases the doctor may need more than 4 incisions Or depending on the circumst2. including associated firmware and software will be free from defects in workmanship and materials for a period of 12 months after the original implantation of the IPG the Warranty Period If it appears that an IPG contains a defect in workmanship or materials or fails to conform to applicable specifications EndoStim will replace the defective or non conforming 14 EndoStim Lower Esophageal Sphincter Stimulation Therapy components free of charge The Warranty Period for a replaced component shall be the longer of the time remaining on the original Warranty Period or nine months from delivery of the replaced item If a system component completely fails to function within the first 72 hours of operation EndoStim will replace the failed item with a new one EndoStim shall not be liable under this warranty if testing and examination discloses that the alleged defect or non conformity in the system component does not exist or was caused by the end user s misuse neglect improper implantation or testing unauthorized attempts to repair or by accident fire lightning or other hazard EndoStim Lower Esophageal Sphincter Stimulation Therapy 15 EndoStim Lower Esophageal Sphincter Stimulation Therapy 17 EndoSt m EndoStim B V Prinsessegracht 20 2514 AP The Hague The Netherlands Toll Free 1 866 5 10 1003 Internet www endostim com Part Number PM 05 Rev C Australia 18 EndoStim Lower Esophageal Sph
