Intended Use

The EndoFLIP® System is indicated for use in a clinical setting to measure pressure and dimensions in the esophagus. pylorus, and anal sphincters. It is intended to be used as an adjunct to other diagnostic methods as part of a comprehensive evaluation of patients with symptoms consistent with gastrointestinal motility disorders. The EF-325 series of catheters can make pressure and dimensional measurements in the esophagus, pylorus, and anal sphincters; whereas the BF-325 series and EF-825 catheters can make dimensional measurements in the esophagus. pylorus, and anal sphincters. The EF-620 catheter can make dimensional measurements in the esophagus. Other indications for use include: · To estimate the size of a stoma produced by a gastric band (all EndoFLIP catheters) · For use as an adjunct to a bougie for measuring the size of a gastric sleeve created during bariatric surgery, where it is suitable for diameter measurements for 22 to 60Fr sleeves (EF-620 catheter)

Device Story

EndoFLIP System uses balloon-based catheter to measure pressure and dimensions in GI tract (esophagus, pylorus, anal sphincters). Catheter contains pressure sensor and 16 impedance electrodes along balloon length. System performs balloon distension via pre-programmed isovolumetric steps (volume/time) or patient-controlled steps. Used in hospitals/physician offices by clinicians. Data saved internally, exportable via USB, or printed. Provides objective measurements of luminal distensibility and pressure to assist in diagnosing motility disorders. Benefits include improved assessment of sphincter function and gastric surgical outcomes.

Clinical Evidence

No new clinical trials conducted for this submission. Evidence consists of 11 peer-reviewed clinical studies evaluating the EndoFLIP system's performance in measuring anal sphincter resistance, pyloric compliance, and esophageal/pharyngo-oesophageal segment distensibility in various patient populations (e.g., fecal incontinence, gastroparesis, post-laryngectomy).

Technological Characteristics

Pneumatic balloon distension system. Catheter features integrated pressure sensor and 16-point impedance electrode array. Operates via pre-programmed isovolumetric inflation steps. Biocompatible materials per ISO 10993-1. Connectivity via USB for data export. No hardware or software changes from predicate.

Indications for Use

Indicated for patients with symptoms consistent with gastrointestinal motility disorders. Used for measuring pressure and dimensions in the esophagus, pylorus, and anal sphincters, estimating gastric band stoma size, and measuring gastric sleeve diameter (22-60Fr). Contraindicated where endoscopy is contraindicated.

Regulatory Classification

Identification

A gastrointestinal motility monitoring system is a device used to measure peristalic activity or pressure in the stomach or esophagus by means of a probe with transducers that is introduced through the mouth into the gastrointestinal tract. The device may include signal conditioning, amplifying, and recording equipment. This generic type of device includes the esophageal motility monitor and tube, the gastrointestinal motility (electrical) system, and certain accessories, such as a pressure transducer, amplifier, and external recorder.

In summary we have found that the following key elements support a determination of substantially equivalent: ### Indications - The proposed indications for use are similar to the predicate. G&J Barostat K991288 when expanded to include the alimentary tract. The other indications for use are identical to the reference, Crospon EndoFLIP® system, K120997 Discussion - The inclusion of the alimentary tract is consistent with the predicate K991288 Distender Series II Dual Drive Barostat and a subset of which are already within the scope of the current EndoFLIP® clearances. ### Environment of Use - The proposed environments of use are identical to the predicate, K991288 Distender Series II Dual Drive Barostat and reference EndoFLIP® K120997 / K092850. Discussion - There have been no changes in the environments of use. ### Patient Population - The proposed patient population is patients with gastrointestinal motility disorders, identical to the predicate K991288 Distender Series II Dual Drive Barostat and reference EndoFLIP® K120997 which list patients with symptoms consistent with gastrointestinal disorders, which are equivalent. Discussion - There have been no changes in the patient population. ### Technology / Design / Features - The technology is identical to the predicate EndoFLIP® systems (K092850) with no hardware or software changes. Discussion - There have been no changes in the proposed device vs. the reference devices. ### Materials - There are no material changes from the predicate K092850. Discussion - The identical accessory catheters are used therefore there have been no changes in the materials in patient contact. ### Performance Specifications - There are no design changes to the system or catheters and therefore no change in performance. Discussion - There have been no changes in the performance specification vs. the reference devices. ### Performance Testing - Bench No comparative bench testing was required as there are no design changes to the system or catheter. ### Performance Testing - Clinical Independent clincial studies have been performed for the cited anatomical locations in the indictaions for use.
