No
The device description details a purely mechanical system using a diaphragm and needle to indicate pressure. There is no mention of any computational or algorithmic processing, let alone AI/ML.
No.
The device is intended to monitor the pressure within an inflatable tracheal tube cuff, providing visual feedback to trained personnel, which is a measurement function rather than providing a therapeutic effect to the patient.
Yes
The device is described as measuring and indicating internal pressure changes within an endotracheal tube cuff, which is a form of measurement used to assess a physiological parameter or condition.
No
The device description clearly details a physical device with mechanical components (silicone diaphragm, indicator arrow/needle, case, valve) that directly measure and indicate pressure. There is no mention of software being involved in its function.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, tissue) to provide information about a person's health.
- Device Function: The PYLANT MONITOR measures the pressure within an inflatable tracheal tube cuff. This is a direct measurement of a physical parameter within a medical device connected to a patient, not an analysis of a biological specimen.
- Intended Use: The intended use is to provide a visual indication of pressure within a tracheal tube cuff, which is a device used to provide an airtight seal. This is a functional measurement related to the performance of a medical device, not a diagnostic test on a patient sample.
The device is clearly a medical device used in the management of a patient's airway, but it does not fit the definition of an In Vitro Diagnostic device.

Device Description
The PYLANT MONITOR is used by personnel trained in pulmonary resuscitation and airway management (ex. anesthesiologists, RN, respiratory therapists, EMT, paramedics) used to measure the trachael cuff pressure of an endotrachael tube or tracheotomy tube by measuring the external pilot line port of the tube.
The Pylant Monitor (PM) is a medical device intended to indicate changes inside an endotracheal tube (ETT) cuff. One end of the PM is fabricated to fit into the "pilot balloon" (international standard for all types of intra-tracheal tubes with a cuff) of the ETT cuff. The other end is fabricated to accept a medical syringe (international standard for all intravenous syringes) for adding or removing air from inside the ETT cuff and altering the volume of air and therefore the pressure inside the ETT cuff. The syringe end of the PM has a one way air tight valve that is open when the syringe is connected. When the syringe is not connected the valve is closed and air is trapped within the ETT cuff and the PM creating the seal between the trachea and cuff. In between the two ends of the PM is a silicone diaphragm that expands and contacts with pressure. As pressure rises the more the diaphragm expands and as pressure falls the diaphragm contracts. Attached to the center of the diaphragm is and indicator arrow/needle. The diaphragm and arrow/needle is housed inside a designed case. The case acts as a protector of the silicone diaphragm arrow needle assembly and is labeled, color coded and calibrated to indicate pressure ranges from 20 cm H20 to 30 cm H20. The PM is designed to remain connected to the ETT pilot balloon and continuously monitor the pressure or monitor pressure intermittently.
Pressure changes within the ETT when connected to the PM are indicated by expansion or contraction of the silicone diaphragm causing calibrated movement of the arrow/needle and indicated on the color coded label.

Description of the test set, sample size, data source, and annotation protocol
The test consisted of 120 randomly selected production Pylant Monitors. The bench testing included the use of a calibrated Pyton regulator used to pressurize the ETT cuff. which is attached to the Monitor through the inlet tube. Each Monitor was attached to the PYTON pressure regular at the check valve.
Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Bench tests of the PYLANT MONITOR were conducted comparing PYLANT MONITOR to an FDA cleared pressure monitor; the PressureEasy K833327. The PYLANT MONITOR pressures were substantially equivalent when compared to the PressureEasy Device.
The objective of the testing is to determine if the Pylant Monitor will register the correct ETT cuff pressure. The scale on the monitor has a "set point" which is approximately 25 CM H20 pressure. The "set point" is the small black line centered in the 20 - 30 mark on the scale. Each Monitor will be pressurized with the PYTON regulator to 25 CM H20 pressure and will register the pressure from the ETT cuff.

In order for the Pylant Monitors to pass, the units must register in the 20 - 30 CM H20 "safe zone". When the Monitors were pressurized to 25 CM H20 pressure all 120 units passed the test by hitting the "mid point" on the scale.
The Pressure Easy devices were tested using the same set-up and test
criteria. This comparative study has been included in Section 18.

5. Description of the Devices
The PYLANT MONITOR is used by personnel trained in pulmonary resuscitation and airway management (ex. anesthesiologists, RN, respiratory therapists, EMT, paramedics) used to measure the trachael cuff pressure of an endotrachael tube or tracheotomy tube by measuring the external pilot line port of the tube.
The Pylant Monitor (PM) is a medical device intended to indicate changes inside an endotracheal tube (ETT) cuff. One end of the PM is fabricated to fit into the "pilot balloon" (international standard for all types of intra-tracheal tubes with a cuff) of the ETT cuff. The other end is fabricated to accept a medical syringe (international standard for all intravenous syringes) for adding or removing air from inside the ETT cuff and altering the volume of air and therefore the pressure inside the ETT cuff. The syringe end of the PM has a one way air tight valve that is open when the syringe is connected. When the syringe is not connected the valve is closed and air is trapped within the ETT cuff and the PM creating the seal between the trachea and cuff. In between the two ends of the PM is a silicone diaphragm that expands and contacts with pressure. As pressure rises the more the diaphragm expands and as pressure falls the diaphragm contracts. Attached to the center of the diaphragm is and indicator arrow/needle. The diaphragm and arrow/needle is housed inside a designed case. The case acts as a protector of the silicone diaphragm arrow needle assembly and is labeled, color coded and calibrated to indicate pressure ranges from 20 cm H20 to 30 cm H20. The PM is designed to remain connected to the ETT pilot balloon and continuously monitor the pressure or monitor pressure intermittently.
Pressure changes within the ETT when connected to the PM are indicated by expansion or contraction of the silicone diaphragm causing calibrated movement of the arrow/needle and indicated on the color coded label.
6. Summary of Performance Data
Bench tests of the PYLANT MONITOR were conducted comparing PYLANT MONITOR to an FDA cleared pressure monitor; the PressureEasy K833327. The PYLANT MONITOR pressures were substantially equivalent when compared to the PressureEasy Device.
6
Description of Performance Test
The objective of the testing is to determine if the Pylant Monitor will register the correct ETT cuff pressure. The scale on the monitor has a "set point" which is approximately 25 CM H20 pressure. The "set point" is the small black line centered in the 20 - 30 mark on the scale. Each Monitor will be pressurized with the PYTON regulator to 25 CM H20 pressure and will register the pressure from the ETT cuff.
The test consisted of 120 randomly selected production Pylant Monitors. The bench testing included the use of a calibrated Pyton regulator used to pressurize the ETT cuff. which is attached to the Monitor through the inlet tube. Each Monitor was attached to the PYTON pressure regular at the check valve.
In order for the Pylant Monitors to pass, the units must register in the 20 - 30 CM H20 "safe zone". When the Monitors were pressurized to 25 CM H20 pressure all 120 units passed the test by hitting the "mid point" on the scale.
The Pressure Easy devices were tested using the same set-up and test
criteria. This comparative study has been included in Section 18.
7. Safety & Effectiveness
By definition, a device is substantially equivalent to a predicate device when the device has the same intended use and the same technological characteristics as the previously cleared predicate device, or has the same intended use and different technological characteristics, and it can be demonstrated that the device is as safe and effective as the predicate device, and that the new device does not raise different questions regarding safety and effectiveness as compared to the predicate device.
Both devices are intended to monitor the pressure inside an ETT cuff. Both devices use a silicone diaphragm that expands and contacts with changes in pressure inside the ETT cuff.
Both devices use a color coded label to indicate pressure changes inside the ETT cuff. Both devices connect to the pilot balloon of an ETT tube and both use a syringe to change volume inside the ETT cuff. Both devices can be left on the pilot balloon for continuous monitoring. The predicate device uses a "plunger" up and down type movement to indicated changes in pressure. The Pylant Monitor uses a "sweep" side to side type movement to indicate changes in pressure. The devices are shaped differently.
lt has been shown in this 510(k) submission that the differences between the Pylant Monitor devices and the predicate devices do not raise any questions regarding their safety and effectiveness, and therefore have been determined to be substantially equivalent to the referenced predicate device.
