The GERDX®-System is indicated for the treatment of symptomatic chronic gastroesophageal reflux disease (GERD) in patients who require and respond to pharmacological therapy.

The GERDX-System is a sterile application and suture system indicated for the treatment of symptomatic chronic gastroesophageal reflux disease (GERD) in patients who require and respond to pharmacological therapy. The GERDX-System consist of following procedural components: GERDX-Applicator, GERDX-Tissue Retractor, GERDX-Suture System and the GERDX-Guide Wire. The Suture System and the Tissue Retractor are loaded onto the Applicator. The Guide Wire is placed within the antrum of the stomach by standard procedure. By use of the Guide Wire, the Applicator is introduced orally and advanced through the esophagus into the stomach. After removing the Guide Wire a thin profile gastroscope is inserted into a channel within the Applicator and the Applicator is positioned under direct endoscopic visualization at the target location within the gastrointestinal (GI) tract. The Tissue Retractor is advanced out of the distal tip of the Applicator. Gastric tissue is engaged by the Tissue Retractor and withdrawn into the Applicator, thereby pulling the tissue into the open arms of the Applicator. The arms of the Applicator are then closed to grasp and approximate the target tissue. The Suture System is then deployed to transmurally affix the GI tissue. The procedure is repeated to deploy additional Suture Systems if necessary. The number of Suture Systems that are placed will vary based on patient anatomy and physician's judgement. Parts of the Suture System remain within the patient.

The EndoGastric Solutions EsophyX Z+ Device with SerosaFuse Fasteners and Accessories is indicated for use in transoral tissue approximation, full thickness plication in the GI tract and is indicated for the treatment of symptomatic chronic gastroesophageal reflux disease in patients who require and respond to pharmacological therapy. It is also indicated to narrow the junction and reduce hiatal hernia ≤ 2cm in size in patients with symptomatic chronic gastroesophageal reflux disease. Patients with hiatal hernias larger than 2cm may be included, when a laparoscopic hiatal hernia repair reduces the hernia to 2cm or less.

The EsophyX Z+ Device with SerosaFuse Fasteners and Accessories is a prescription use only, disposable, single-use, sterile system consisting of an all-mechanical, flexible fastener delivery device with user controls outside the patient's body. The transoral device and tissue fasteners are provided sterile by ethylene oxide (EO). The delivery device is limited contact and materials include acrylic/polycarbonate plastics, machined aluminum, stainless steel, nitinol wire, UV cured adhesives, pellethane and nylon. The permanent contact, implantable SerosaFuse tissue fasteners are constructed of injection molded polypropylene and are of a strength equivalent to 3-0 suture. The SerosaFuse Implantable Fastener Cartridge is dual-lever containing 20 fasteners in each lever, and is designed to be removable. Each fastener consists of a leading leg, interconnecting web and trailing leg. The fastener's unique design allows it to be loaded onto a stylet, passed into and down a small delivery lumen of the device and subsequently delivered through apposed tissue surfaces in the GI tract. When deployed in tissue, the fastener serves as a suture-like implantable. The system is used in an operating room environment, using the Transoral Incisionless Fundoplication (TIF) procedure. The EsophyX Z+ device deploys the SerosaFuse fastener during an endoscopic procedure. A separate commercial endoscope operating independently down the center of the device's flexible shaft lumen provides visualization of the procedure from device insertion through extraction. The EsophyX Z+ device is capable of transoral tissue approximation, ligation, and full thickness plication in the GI tract. The process essentially mimics the standard surgical technique of grasping tissue and apposing/approximating the tissue, piercing, and suturing the tissue fold. Each of these steps is controlled at the device proximal end, though plication, ligation and gastroesophageal valve formation is accomplished at the distal end of the device.

The EndoGastric Solutions EsophyX Device models (EsophyX2 HD and EsophyX Z, K171307) with SerosaFuse Fasteners and Accessories are a prescription use only, disposable, single use systems consisting of an all mechanical, flexible fastener delivery device with user controls outside the patient's body. The devices are used in an operating room environment, using the Transoral Incisionless Fundoplication (TIF) procedure. The device is limited contact and materials include acrylic/polycarbonate plastics, machined aluminum, stainless steel, nitinol wire, UV cured adhesives, pellethane and nylon. The permanent contact, implantable tissue fasteners are constructed of injection molded polypropylene. These transoral devices and tissue fasteners are provided sterile (EO). A separate, commercial endoscope operating independently down the center of the devices' flexible shaft lumen provides visualization of the procedure at all times, from device insertion through extraction. Two fasteners are loaded from a replaceable fastener cartridge containing ten fasteners for each channel. The loaded fasteners are pushed from the proximal device end, to the distal end down two separate channels via lumens in a flexible shaft where they are then in position ready for deployment into tissue. The operator, controlling the distal end of the devices through the mechanical controls at the proximal end of the devices, captures and positions a fold of tissue at the gastroesophageal junction. The fastener controls deploy both fasteners simultaneously in the EsophyX Z model, or individually in the EsophyX2 HD model, at the captured tissue position. This creates a permanent surgical partial fundoplication. Additional fasteners are used as needed to complete the valve restoration.

The EndoGastric Solutions EsophyX® 2 HD Device with SerosaFuse is indicated for use in transoral tissue approximation, full thickness plication in the GI tract and is indicated for the treatment of symptomatic chronic gastroesophageal reflux disease in patients who require and respond to pharmacological therapy. It is also indicated to narrow the gastroesophageal junction and reduce hiatal hernia < 2cm in size in patients with symptomatic chronic gastroesophageal reflux disease.

The EndoGastric Solutions EsophyX® 2 HD Device with SerosaFuse Fasteners and Accessories consists of an all mechanical, flexible fastener delivery device with user controls outside the patient's body and sterile polypropylene fasteners delivered transorally through a flexible shaft into the GI tract via a common delivery mechanism comprised of three elements: a stylet, a pusher rod, and a delivery tube. All three fastener delivery elements run the length of the delivery device. The stylet runs down the inside of the lumen of the delivery tube and the pusher rod rides over the length of the stylet. The stylet is designed to pierce and hold the desired tissue plication in place and guide the fastener into position. There are two separate tubes or channels in the device, referred to as the posterior and anterior channels. A fastener is loaded mechanically onto the stylet via a replaceable fastener cartridge containing ten fasteners for each channel. To load, the fastener cartridge lever is depressed, which snaps a fastener onto the stylet. The fastener is then pushed down the stylet from the proximal handle assembly to the distal tissue port via the pusher rod where it is then ready to be deployed into the tissue. When the desired tissue approximation/ plication is achieved, the pusher rod is used to push the fastener into the tissue, quided by the stylet which precedes it into the tissue. The leading leq of the fastener slides along the stylet into the tissue. Slight additional pressure advances the pusher causing the leading leg of the fastener to disengage from the stylet and the fastener then seats across the desired tissue plication. A new fastener is loaded proximally in the device at the loading port, after retracting the pusher rod. The loading and fastening procedure can be repeated. The device is provided sterile and is a single use device.
