Intended Use

The Navina Classic System is indicated for adults who suffer from fecal incontinence, chronic constipation, and/or time consuming bowel management. The Navina Classic System is intended to promote evacuation of the colon and rectum by instilling water into the lower part of the colon through a rectal catheter which incorporates an inflatable balloon.

Device Story

Navina Classic System is a manual anal irrigation device for bowel management. Components include a single-use rectal catheter with an inflatable balloon, a water container, a manual control unit, and tubing. The device is used in healthcare facilities or at home by patients or caregivers. Operation involves manual inflation of the rectal balloon to secure the catheter, followed by manual instillation of lukewarm water into the lower colon to trigger peristalsis and evacuation. The system is non-powered and relies on manual control for water flow and balloon pressure. It provides a mechanical method for bowel evacuation, assisting patients with chronic constipation or fecal incontinence.

Clinical Evidence

No clinical data provided. Substantial equivalence is supported by non-clinical bench testing, including control unit performance (flow rate, pump force, balloon deflation), rectal catheter performance (balloon burst volume/diameter, coating integrity, flow rate), and system backflow verification. Biocompatibility testing (ISO 10993-5, -10, -3) confirms the device is non-cytotoxic and non-irritating.

Technological Characteristics

Manual anal irrigation system. Components: rectal catheter with hydrophilic coating, water container, manual control unit, tubing. Materials meet ISO 10993 biocompatibility standards. Balloon inflation via air; irrigation via lukewarm water (97-100 °F). Non-sterile, single-use catheter; reusable control unit/tubing. No software or electronic components.

Indications for Use

Indicated for adults suffering from fecal incontinence, chronic constipation, and/or time-consuming bowel management. Contraindicated in patients with anal/colorectal stenosis, colorectal cancer, active inflammatory bowel disease, acute diverticulitis, within 3 months of rectal surgery, within 4 weeks of endoscopic polypectomy, ischemic colitis, spinal cord shock phase, complex diverticular disease, or pregnancy.

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. The class I device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to § 876.9.

Non-Clinical Performance Data:

The performance testing is divided into three parts; control unit, water container, rectal catheter, connectors, and system testing.

Performance testing of the control unit included:

- Control of air leakage
- Complete deflation of balloon (air release)
- Control of maximum pump force
- Ability to instantly stop water flow
- Control of water flow rate

Performance testing of the rectal catheter included:

- Hydrophilic coating at insertion and withdrawal
- Flexibility
- Even balloon inflation
- Balloon burst diameter
- Balloon burst volume
- Rectal catheter flow rate
- Rectal catheter flow rate after catheter kink

Performance testing of the water container included:

- Proper air pressure
- Accuracy of the scale of the water container

Performance testing of the connectors included:

- Control of air leakage
- Tensile and torque resistance after simulated repeated use.

Performance testing of the Navina Classic System included:

- System backflow verification testing
The performance of the Navina Classic System satisfactorily met the requirements of the non-clinical bench testing conducted to support substantial equivalence

Biocompatibility has been assured by Cytotoxicity (ISO10993-5:2009), Irritation (ISO10993-10:2010), Sensitization (ISO10993-10:2010) and Genotoxicity (ISO10993-3:2014) analyses. The results of this testing demonstrates that the Navina Classic System is non-cytotoxic, non-irritating in support of substantial equivalence.

Additional analysis has been included to verify the potential for leachable compounds to be present after simulated repeated use. The results of this testing support substantial equivalence.

## Clinical Performance Data:

No data from human clinical studies have been included to support the substantial equivalence of the Navina Classic System.

{11}------------------------------------------------

# Conclusion Regarding Substantial Equivalence:

The Navina Classic System is a device for Anal Irrigation. By instilling water up into the lower part of the colon, through a rectal catheter, which incorporates an inflatable balloon, the peristaltic muscles in the bowel can be triggered and start to evacuate the colon and rectum.

The proposed Navina Classic System has the same intended use, incorporates the same fundamental technology, and has similar indications for use as does the predicate Peristeen Anal Irrigation System cleared under premarket K140310. The proposed device has a more narrowly defined indicated patient population when compared to the indicated use of the predicate device. Test data to verify the specified performance requirements of the subject device has been included. The results of this testing combined with the design, biocompatibility, and intended use comparison to the predicate device support the substantial equivalence of the Navina Classic System.
