Indications for Use
The McLean-Ring Nasojejunal Feeding Tube Set is intended for enteral feeding and medication in adult and pediatric populations. The device is intended to be used in the treatment of the following pediatric subgroups: children and adolescents.
Device Story
The McLean-Ring Nasojejunal Feeding Tube Set is a 9.5 French polyurethane feeding tube with a stainless steel distal weight and a 0.038-inch PTFE-coated stainless steel wire guide. The device is used to provide enteral nutrition and medication to the gastrointestinal tract. It is introduced either via peristalsis or by passing the tube over the wire guide through the external naris, pylorus, and duodenum. The device is intended for indwelling use for up to 30 days and is for one-time use. It is intended for use in adult and pediatric populations (children and adolescents). The device is used in clinical settings to facilitate feeding in patients who cannot orally ingest nutrition. By providing direct access to the small bowel, it ensures delivery of nutrition and medication, potentially improving patient outcomes in those with gastrointestinal or nutritional challenges.
Clinical Evidence
No clinical data was generated for this specific device. The manufacturer provided a literature review of six studies involving 6F, 8F, and 10F post-pyloric feeding tubes in pediatric patients (ages ranging from neonates to 24 years). Studies included prevalence, prospective cohorts, and retrospective case series. Reported outcomes included placement success rates (up to 99%) and adverse event profiles (e.g., accidental removal, unsuccessful placement due to anatomical factors). The literature supports the safety and performance of using such tubes in children (2 years and older) and adolescents.
Technological Characteristics
9.5 French polyurethane feeding tube; 130 cm length; 0.650-inch stainless steel distal weight covered in shrink tube; 0.038-inch PTFE-coated stainless steel wire guide; six distal sideports; rounded distal tip with endhole. Sterilization: ETO (SAL 10^-6). Packaging: Tyvek peel-open pouch. No software or electronic components.
Indications for Use
Indicated for enteral feeding and medication delivery in adult and pediatric patients, specifically children and adolescents.

# Predicate Device:
The McLean-Ring Enteral Feeding Tube Set is substantially equivalent to the following device: Tiger 2 Self-Advancing Nasal Jejunal Feeding Tube (K160509, Cook Incorporated) cleared on May 18, 2017.
## Device Description:
The McLean-Ring Nasojejunal Feeding Tube Set is composed of a feeding tube and wire guide. The feeding tube is made of a 9.5 French polyurethane tube. The feeding tube is available in 130 centimeters only, measured from the distal tip to the proximal hub. The distal end of the feeding tube features six sideports. The distal tip of the feeding tube is open with a smooth round finish. A 0.650-inch long stainless steel weight is fit outside the distal end of the feeding tube and is completely covered with a shrink tube, forming 0.180-inch outer diameter over the weight. The proximal end of the feeding tube features a hub with a cap that is made of polyurethane.

Image /page/4/Picture/0 description: The image shows the logo for Cook Medical. The logo consists of the word "COOK" in large, white, sans-serif font on a red square. Below the red square is a smaller, darker red rectangle with the word "MEDICAL" in white, sans-serif font.
The wire guide is made of stainless steel in a 0.038-inch diameter. The wire guide is 275 centimeters long. In addition, the entire length of the wire guide is coated with PTFE. The distal end of the wire guide is straight but flexible.
The subject device, McLean-Ring Nasojejunal Feeding Tube Set, may be introduced directly when there is adequate peristalsis and no gastric outlet obstruction. Alternatively, the feeding tube may be passed over a wire guide. The feeding tube is intended to be indwelling up to 30 days and is for one-time use.
# Indications for Use:
The McLean-Ring Nasojejunal Feeding Tube Set is intended for enteral feeding and medication in adult and pediatric populations. The device is intended to be used in the treatment of the following pediatric subgroups: children and adolescents.
# Comparison to Predicate Device:
The subject device, McLean-Ring Nasojejunal Feeding Tube Set, and the predicate device, the Tiger 2 Self-Advancing Nasal Jejunal Feeding Tube (K160509), are substantially equivalent in that these devices have a similar intended use, technological characteristics, placement location, indwell time, sterilization method, and packaging. The subject device and predicate device similarly establish an enteral delivery for feeding and medication. The subject device and predicate device have identical characteristics including the number of sideports on the distal end of the catheter and rounded distal tip. The subject device and predicate device pass through the patient's oropharynx before descending the gastrointestinal track to the intended access site. The predicate device's access sites are the stomach or the small bowel; the subject device's access sites are the pylorus or the duodenum, which lie between or are part of the stomach and small bowel.
The differences between the subject and the predicate device including the materials of construction, catheter dimensions, distal tip features, mode of operation, and intended patient population do not raise any new issues of safety and/or effectiveness.
Similarities and differences in technological characteristics are captured in the substantial equivalence comparison of the subject device, McLean-Ring Nasojejunal Feeding Tube Set, and the predicate device, Tiger 2 Self-Advancing Nasal Jejunal Feeding Tube, which is provided in Table 1.

These data do not identify additional potential adverse events that are not covered in the proposed IFU of the subject device. The clinical literature summarized in Table 2 provides supporting evidence that the subject device is appropriate for use in children (2 years and older) and adolescents and raises no new question of safety and/or effectiveness.
#### Conclusion:
The results of these tests confirm that the McLean-Ring Nasojejunal Feeding Tube Set meets the design input requirements based on the intended use and support the conclusion that this device does not raise new questions of safety and/or effectiveness and is substantially equivalent to the predicate device, the Tiger 2 Self-Advancing Nasal Jejunal Feeding Tube (K160509, Cook Incorporated).
