Intended Use

The USGI Endoscopic Overtube is intended to be used with an endoscope to facilitate intubation, e.g., colonoscopy, change of endoscopes, removal of multiple polyps and/or foreign bodies.

Device Story

USGI Endoscopic Overtube is an endoscopic accessory providing external support to an endoscope. Device consists of multiple nested, bowl-shaped links held by four tension cables connected to an atraumatic tip. Operation: practitioner inserts endoscope through overtube; once desired configuration is reached, tension is applied to cables via handle, increasing friction between links to 'shape lock' the tube. Locked configuration allows repeated advancement or withdrawal of the endoscope without losing the established shape. Used in clinical settings (e.g., endoscopy suites) by physicians to facilitate procedures like colonoscopy, endoscope changes, and polyp/foreign body removal. Benefits include improved scope stability and maneuverability during complex endoscopic interventions.

Clinical Evidence

Bench testing only. Mechanical and functional testing demonstrated that the device performs as intended. No clinical data provided.

Technological Characteristics

Shape-locking tube with nested links, four tension cables, atraumatic tip, slip-coated inner liner, and handle. Mechanical friction-based locking mechanism. Patient-contacting materials have established history of biocompatibility. Manual operation.

Indications for Use

Indicated for use with an endoscope to facilitate intubation, including colonoscopy, endoscope exchange, and removal of polyps or foreign bodies in patients requiring endoscopic procedures.

Regulatory Classification

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. The device consists of various rigid or flexible instruments that are inserted into body spaces and may include an optical system for conveying an image to the user's eye and their accessories may assist in gaining access or increase the versatility and augment the capabilities of the devices. Examples of devices that are within this generic type of device include cleaning accessories for endoscopes, photographic accessories for endoscopes, nonpowered anoscopes, binolcular attachments for endoscopes, pocket battery boxes, flexible or rigid choledochoscopes, colonoscopes, diagnostic cystoscopes, cystourethroscopes, enteroscopes, esophagogastroduodenoscopes, rigid esophagoscopes, fiberoptic illuminators for endoscopes, incandescent endoscope lamps, biliary pancreatoscopes, proctoscopes, resectoscopes, nephroscopes, sigmoidoscopes, ureteroscopes, urethroscopes, endomagnetic retrievers, cytology brushes for endoscopes, and lubricating jelly for transurethral surgical instruments. This section does not apply to endoscopes that have specialized uses in other medical specialty areas and that are covered by classification regulations in other parts of the device classification regulations.

#### TECHNICAL CHARACTERISTICS:

The USGI Endoscopic Overtube is a shape locking tube with an atraumatic tip, a slip coated inner liner, a smooth outer skin, and a handle. The overtube is constructed from multiple nested links that are held together by four cables. Each link is bowl shaped, but without a bottom and has four equally spaced annular holes running longitudinally through the wall thickness. The purpose of the holes is to accommodate the tension wires which pass through each link. The wires are connected to the tip but slide freely through all other links. Applying tension to the wires squeezes the links together. The friction between links maintains their relative positions, allowing the practitioner to "lock in" a shape.

#### PERFORMANCE DATA:

All components that come in direct contact with the patient have a long history of use in medical devices and are biocompatibile This 510(k) notice includes mechanical and functional bench testing that demonstrate that the USGI Endoscopic Overtube performs as intended.

#### BASIS FOR DETERMINATION OF SUBSTANTIAL EQUIVALENCE:

The USGI Endoscopic Overtube is substantially equivalent to the Olympus ST-C3 Overtube (cleared for market under K903842), the Bard Endoscopic Overtube (cleared for market under K973500), and the NDO Surgical, Inc. Overtube (cleared for market under K002018). All four devices have the same indication for use and are made of the same materials (patient-contacting materials). Bench testing demonstrates that the devices are functionally equivalent.
