Intended Use

The GIBI HD™ is indicated for use in gastric and bariatric surgical procedures to decompress the stomach, drain and remove gastric fluid, irrigate, and act as a sizing guide.

Device Story

GIBI HD is a flexible, dual-lumen gastric catheter used during gastric and bariatric surgeries. One lumen facilitates drainage, suction, and irrigation; the second lumen manages balloon inflation/deflation. The device provides visible and tactile delineation of the stomach antrum and serves as a sizing guide for the gastric pouch. It is operated by surgeons in a clinical/surgical setting. The device includes a 32-inch suction tube and a 6-inch fill tube with a stopcock. By providing a calibrated sizing guide and drainage capability, it assists the surgeon in performing bariatric procedures, potentially improving surgical outcomes.

Clinical Evidence

Bench testing only. Performance data included balloon leakage testing (100 cc retention), fluid removal testing (500 cc in <1 minute), and mechanical bond strength testing for the balloon, distal tip, stopcock, fill tube, and adapter components (all meeting minimum lbf requirements). Visual and measurement verification confirmed catheter length (75 cm), indicator mark placement (30-60 cm), and outer diameter sizing (32, 36, and 40 Fr).

Technological Characteristics

Dual-lumen flexible catheter; material: silicone; dimensions: 32 Fr, 36 Fr, and 40 Fr outer diameters; working length ~32.43 inches; includes integrated balloon, suction tubing, and stopcock-controlled fill tube. Non-sterile. No electronic or software components.

Indications for Use

Indicated for use in gastric and bariatric surgical procedures for stomach decompression, gastric fluid drainage/removal, irrigation, and gastric pouch sizing.

Regulatory Classification

Identification

A gastrointestinal tube and accessories is a device that consists of flexible or semi-rigid tubing used for instilling fluids into, withdrawing fluids from, splinting, or suppressing bleeding of the alimentary tract. This device may incorporate an integral inflatable balloon for retention or hemostasis. This generic type of device includes the hemostatic bag, irrigation and aspiration catheter (gastric, colonic, etc.), rectal catheter, sterile infant gavage set, gastrointestinal string and tubes to locate internal bleeding, double lumen tube for intestinal decompression or intubation, feeding tube, gastroenterostomy tube, Levine tube, nasogastric tube, single lumen tube with mercury weight balloon for intestinal intubation or decompression, and gastro-urological irrigation tray (for gastrological use).

Special Controls

*Classification.* (1) Class II (special controls). The barium enema retention catheter and tip with or without a bag that is a gastrointestinal tube and accessory or a gastronomy tube holder accessory is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 876.9.(2) Class I (general controls) for the dissolvable nasogastric feed tube guide for the nasogastric tube.

#### BASIS FOR SUBSTANTIAL EQUIVALENCE VI.

Substantial equivalence of the GIBI HD to the predicate device (Lap-Band® System Calibration Tube, K220455) was established through an evaluation of the indications for use, principle of operation, device design, materials of construction, and an assessment of usability, safety, and effectiveness via bench studies.

The data presented in this summary demonstrates the technological similarity and equivalency of the GIBI HD to the predicate device (Lap-Band® System Calibration Tube, K220455).

The devices:

- · have the same intended use,
- · use the same principle of operation,
- · incorporate the same basic design,
- · use similar construction and material, and
- · are provided non-sterile.

In addition, the GIBI HD and the reference device (ViSiGi 3D, K130483) have the same outer

diameter sizes and are substantially equivalent with respect to working length.

In summary, the Gastrointestinal Boundary Identifier (GIBI HD™) device described in this submission is substantially equivalent to the predicate device, the LAP-BAND System Calibration tube (K220455).
