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.

### Table 6-1 Substantial Equivalence Discussion- Oral/Enteral Syringe with ENFit connector

{5}------------------------------------------------

Difference comment 1

The Gasket of the subject device is not covered by the predicate device, but the Oral/Enteral Syringe with ENFit connector of the structure has passed the verification of ISO 80369-3, ISO 80369-20 and ISO 7886-1 standard tests, and the results meet the

{6}------------------------------------------------

requirements. Therefore, this difference does not raise new safety and effectiveness issues for the device.

#### Difference comment 2

The product size for subject device is different from predicate device. The subject device includes 12 sizes, 0.5ml, 1ml, 2.5ml/3ml, 10ml/12ml, 20ml, 30ml, 30ml, 35ml, 60ml all of which are covered by predicative device. but after the test of product performance, the safety and effectiveness of the product have been verified. In addition, this difference is just in infusion capacity and dose not effect indication for use, and the physician can select by per patient's condition. Therefore, this difference does not raise new safety and effectiveness issues for the device.

### Difference comment 3

subject device is different from predicate device in material, but the main material of the device is PP. However, the biocompatibility test has been performed on proposed device according to ISO 10993, the result does not show any adverse effect which can demonstrate the safety of proposed device. Therefore, this difference does not raise new safety and effectiveness issues for the device.

#### VII Performance data
