The DiLumen dual balloon accessory is intended for use with any standard endoscope that has a distal tip outer diameter of 12.5 - 14.3 mm and a working length of 1680 mm or greater. The device is indicated to ensure complete positioning of an endoscope in the large intestine, and assist with optical visualization, diagnosis, and endoscopic treatment. ## Device Story DiLumen is a single-use, close-fitting sleeve accessory for standard endoscopes; used in large intestine procedures. Device features two balloons: an Aft Balloon attached to the sleeve and a Fore Balloon deployed via flexible extension push rods at the distal end of the endoscope. Clinician manually inflates/deflates balloons using an inflation handle with a squeeze bulb (ambient air). Once inflated, balloons stabilize the endoscope and create an isolated diagnostic or therapeutic zone within the colon. Allows use of standard endoscopic tools (forceps, snares) through the endoscope working channel. Does not interfere with endoscope visualization or maneuverability. Benefits include improved endoscope positioning and stabilization for complex endoscopic interventions. ## Clinical Evidence Bench testing only. No clinical data provided. Performance testing included biocompatibility, balloon burst pressure, inflation/deflation/leakage, relief valve, device slip, sleeve buckling, fore balloon extension, colon grip, articulation, therapeutic zone creation, fatigue/cycling, extension position locking, flexibility, force/bond, insertion force, packaging/transit, and user validation. ## Technological Characteristics Non-sterile, single-use sleeve accessory. Features dual-balloon system (Aft and Fore) for stabilization. Manual inflation system using ambient air via squeeze bulb. Compatible with standard endoscopes (12.5-14.3 mm distal tip). Mechanical operation; no electronic or software components. ## Regulatory Identification An endoscope and accessories is a device used to provide access, illumination, and allow observation or manipulation of body cavities, hollow organs, and canals.

Fujinon EC-450B15 Double Balloon Enteroscopy System (K090116) - Smart Medical Systems NaviAID™ BGE (K060923) (reference device) ● - Smart Medical Systems NaviAID™ BGC (K102616) (reference device) ● #### Intended Use / Indications for Use: The Lumendi DiLumen is an accessory to an endoscope. The DiLumen dual balloon accessory is intended for use with any standard endoscope that has a distal tip outer diameter of 12.5 – 14.3 mm and a working length of 1680 mm or greater. The device is indicated to ensure complete positioning of an endoscope in the large intestine, and assist with optical visualization, diagnosis, and endoscopic treatment. #### Device Description/Technological Characteristics: The DiLumen Endolumenal Interventional Platform is a non-sterile, single-use, close-fitting sleeve that fits securely over a standard endoscope. {4}------------------------------------------------ The DiLumen utilizes two balloons to position and stabilize the endoscope within a patient's large intestine. After the DiLumen is installed over the endoscope, the endoscope and DiLumen are navigated to the target zone with the balloons deflated. Once the clinician is at the area of interest, the Aft Balloon, which is attached to the DiLumen sleeve, will be inflated until it contacts the intestinal wall near the proximal end of the articulating section of an endoscope. The second balloon, the Fore Balloon, is also attached to the sleeve via two flexible extension push rods and is deployed at the distal end of the endoscope at a variable distance. Once extended and inflated, the Fore Balloon contacts the patient's intestinal wall, and in combination with the Aft Balloon, creates an isolated diagnostic or therapeutic zone. Both balloons are controlled using an Inflation Handle with a squeeze bulb to manually inflate and deflate the two balloons with ambient air. The balloons assist in stabilizing the endoscope and the therapeutic area and are inflated or deflated independently. The balloons and sleeve are designed to permit the usage of any standard endoscopic tool (such as biopsy forceps, snare, needle, etc.) through the endoscope working channel. The endoscope flexibility, maneuverability and functionalities (such as visualization, insufflations, etc.) are unaffected by the presence of the DiLumen. ### Substantial Equivalence: The DiLumen device has the same intended use and similar indications and technological characteristics as the Fujinon EC-450B15 system (K090116) and Smart Medical Systems' NaviAID™ BGE (K060923) and NaviAID™ BGC (K102616) devices. The subject device and the Fujinon predicate consist of the same basic components to ensure complete positioning of the endoscope - specialized balloons, an over-tube/sleeve, and an inflation system; the NaviAid reference devices do not have a sleeve but include a balloon(s) and inflation/extension tube. While the DiLumen is not used to advance the endoscope to the target location like the Fujinon predicate, it shares key functional characteristics including balloon inflation pressure, extension of a balloon from the endoscope distal tip at a variable distance, and use of the balloons to stabilize the endoscope. The balloon diameter is also the same in the DiLumen and the NaviAID™ BGC; the balloons in the NaviAid™ BGE and Fujinon predicate are slightly smaller to accommodate use in the small intestine. The DiLumen and its predicate and reference devices are prescription-use devices used by medical professionals in a healthcare facility. Each device is intended for single use only and should not be re-used. Performance testing has demonstrated that the DiLumen meets specifications and is as safe and effective as the cited predicates. In sum, the minor technological differences between the DiLumen and its predicate and reference devices do not raise different types of safety or efficacy questions; as such, the DiLumen can be found substantially equivalent. #### Performance Data: The following performance data were provided in support of this Premarket Notification: - 1. Biocompatibility (cytotoxicity, sensitization, and systemic toxicity) - 2. Balloon Burst Pressure Test - 3. Balloon Diameter, Inflation/Deflation and Leakage Test {5}------------------------------------------------ - 4. Relief Valve Test - 5. Device Slip Relative to Scope Test - 6. Sleeve Buckling Test - 7. Fore Balloon Extension Test - 8. Colon Grip Test - 9. Articulation Test - 10. Sleeve Leak Test - 11. Therapeutic Zone Creation Test - 12. Fatigue/Cycling Test - 13. Extension Position Locking Test - 14. Flexibility Test - 15. Force/Bond Test - 16. Insertion Force Test - 17. Packaging and Transit Test - 18. User Validation ## Conclusion: From the data presented it is concluded that the subject device is substantially equivalent to the predicates based on intended use/indications for use and technological characteristics. The minor technological differences between the DiLumen and its predicate devices raise no new issues of safety or effectiveness. Bench testing data demonstrate that the DiLumen has substantially equivalent performance to the predicates. --- **Source:** [https://fda.innolitics.com/submissions/GU/subpart-b%E2%80%94diagnostic-devices/FDF/K162428](https://fda.innolitics.com/submissions/GU/subpart-b%E2%80%94diagnostic-devices/FDF/K162428) **Published by [Innolitics](https://innolitics.com)** — a medical-device software consultancy.
