No
The device description clearly outlines physical components made of materials like PVC, including an insertion tube, Y extension, suction regulating valve, and pinch clamp. This indicates a hardware-based medical device, not a software-only one.
Based on the provided information, the ZZIREN™ Orogastric Tube is not an IVD (In Vitro Diagnostic) device.
Here's why:
- Intended Use: The intended use is for gastric and bariatric surgical procedures for gastric aspiration and lavage, to serve as a size guide, and to test for leaks. These are all procedures performed in vivo (within the living body).
- Device Description: The device is a tube designed to be inserted into the stomach or intestine. It is used for physical manipulation and interaction with the internal anatomy.
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens (like blood, urine, or tissue) taken from the body to provide information about a person's health. The ZZIREN™ Orogastric Tube does not perform this function.
The device is clearly intended for direct use within the patient's body during surgery, not for analyzing samples outside the body.

Device Description
The ZZIREN™ Orogastric Tube is a non-sterile, single use device comprising a 37-inch-long insertion tube, a Y extension containing a suction regulating valve, and a pinch clamp. An accessory straight connector is included. The insertion is made of flexible polyvinylchloride (PVC). The suction requlating valve limits negative pressure applied to the stomach or intestine to less than 175 mmHg, produces an audible signal when the suction pressure exceeds ~160 mmHg, and is identical in all models. All six models have multiple apertures in proximity to a rounded distal tip. Three of the models, ZZ-SGT-36, ZZ-SGT-40 have side-holes extending 13 cm from the tip, and three models, ZZ-GBT-36, and ZZ-GBT-40, have side-holes extending 6 cm from the tip. The insertion tubes have diameters of 32, 36, and 40 Fr and humeric markings to indicate depth of insertion.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The stiffness, compressibility, and propensity to kink of the insertion tubes of the proposed device are compared to the those the primary and secondary predicates. The pinction of the proposed device is compared to the function of the same part on the primary predicate. Accessory tubing connectors are shown to fit and function well. The proposed device is shown to be compatible with a device for leak testing.
The INSERTION TUBE KINK TEST data shows that the six models of the proposed ZZIREN™Orogastric Tube are substantially equivalent in their propensity to kink to the predicate SIREN SGT™ and are therefore as unlikely to interfere with gastric decompression, lavage, and stapling. The INSERTION TUBE STIFFNESS TEST shows that all models of the proposed device are equally or less stiff than the insertion tubes of their corresponding predicate device and are therefore equally or less likely to cause visceral injury. The INSERTION TUBE COMPRESSION TEST shows that all models of the proposed device are equally or less likely to be inadvertently stapled during gastric surgery than the corresponding predicate device. The PINCH CLAMP TEST shows that the performance of the PINCH CLAMP on the proposed ZZIREN™ Orogastric Tube is substantially equivalent to its performance on the predicate SIREN SGT™. The CONNECTOR TESTS show that both accessory straight tubing connectors attach to the proposed device easily and reversibly in a secure manner and provide a reliable connection to medical suction tubing. The AlR SYRINGE COMPATIBILITY TEST shows that the pariativ Air Syringe are compatible and may be safely used together for leak testing. Dimensional Analysis Tests of all models of the proposed ZZIREN™ device show that all models are made to design specifications.

Indications for Use Comparison
21 CFR 807.92(a)(5)
The ZZIREN™ Orogastric Tube is indicated for use in gastric surgical procedures for gastric aspiration and lavage, to serve as a sizing guide, and to test for leaks. The Inclusion of "to test for ZZIREN™ Orogastric Tube differs from the indication stated for the primary predicate device in Submission K220218. "To test for leaks" is included in the indications for use of the secondary reference ViSiGi® 3D, which was cleared per Special 510(k) K234145. Use of ZZREN™ Orogastric Tube for leak testing allows the surgeon to more efficiently assess staple line integrity intraoperatively and does not impact the procedures overall safety and effectiveness or the intended use of the device to assist in completion of gastric and bariatric surgery.
Technological Comparison
The proposed Tools for Surgery™ ZZIREN™ Orogastric Tubes, models ZZ-SGT-30, ZZ-GBT-32, ZZ-GBT-36, and ZZ-GBT-40 have technical characteristics similar to that of the primary predicate device, Tools for Surgery™ SIREN SGT™ gastrointestinal tube. All devices are orogastric tubes comprised of biocompatible elastomeric materials.
The proposed devices differ from the predicate device, SIREN SGT™ model SGT-36, by having a Y extension in place of three separate parts (Y connector, extension tube, and suction connector), by having the additional insertion tube calibers of 32 and 40 Fr, and by having 32, 48, 72, or 108 distal apertures (side-holes) instead of the 18 or 36 distal apertures specified in the predicate's 510(k) submission (K220218). (The ViSiGi 3Dº model 5236 [510(k) no. K130483], the antecedent predicate device for K220218, has 108 side holes.)
The Y extension is a single, integral, molded unit having a forward stem to join with the insertion tube, a first arm to contain the suction regulating valve, and a second arm having a segment around which the pinch clamp is disposed, and a rearward expansion to receive a straight connector accessory that is attachable to medical suction tubing. All proposed models have similar Y extensions but different insertion tube calibers or number of apertures. All models employ the same pirmary predicate device to interrupt suction. All models, proposed and precical index markings to help the surgeon and anesthesiologist gauge the depth of insertion and the position of the tube within the upper gastrointestinal tract.
All models, proposed and predicate, connect to a vacuum source in order to deliver neqative pressure to the gastion pressure delivered by the vacuum source is adjustable by means of an external vacuum source suction regulator. All models, proposed and primary predicate, incorporate an identical integral suction regulating valve, which serves as additional means for limiting negative pressure applied to the gastric mucosa. This is a pressure relief valve, which opens at 103 to 155 mm Hg and limits the pressure in the insertion tube and stomach to less than negative 175 mm Hq when full suction (~360 mm Hq) is applied. When negative pressure within the insertion tube of any model, proposed or primary predicate, exceeds 160 mm Hg an audible signal produced by mechanical means by the suction regulating valve informs the operator that excessive suction is being applied, and prompts the operator to lower the suction pressure by manually adjusting the vacuum source suction regulator.
Non-Clinical and/or Clinical Tests Summary & Conclusions 21 CFR 807.92(b)
The stiffness, compressibility, and propensity to kink of the insertion tubes of the proposed device are compared to the those the primary and secondary predicates. The pinction of the proposed device is compared to the function of the same part on the primary predicate. Accessory tubing connectors are shown to fit and function well. The proposed device is shown to be compatible with a device for leak testing.
The INSERTION TUBE KINK TEST data shows that the six models of the proposed ZZIREN™Orogastric Tube are substantially equivalent in their propensity to kink to the predicate SIREN SGT™ and are therefore as unlikely to interfere with gastric decompression, lavage, and stapling. The INSERTION TUBE STIFFNESS TEST shows that all models of the proposed device are equally or less stiff than the insertion tubes of their corresponding predicate device and are therefore equally or less likely to cause visceral injury. The INSERTION TUBE COMPRESSION TEST shows that all models of the proposed device are equally or less likely to be inadvertently stapled during gastric surgery than the corresponding predicate device. The PINCH CLAMP TEST shows that the performance of the PINCH CLAMP on the proposed ZZIREN™ Orogastric Tube is substantially equivalent to its performance on the predicate SIREN SGT™. The CONNECTOR TESTS show that both accessory straight tubing connectors attach to the proposed device easily and reversibly in a secure manner and provide a reliable connection to medical suction tubing. The AlR SYRINGE COMPATIBILITY TEST shows that the pariativ Air Syringe are compatible and may be safely used together for leak testing. Dimensional Analysis Tests of all models of the proposed ZZIREN™ device show that all models are made to design specifications.
