The document mentions a "proprietary ECOM algorithm" and the need to "develop an algorithm for clinical applications and to calibrate the algorithm using actual clinical data." While this indicates the use of a complex algorithm and data-driven development, it does not explicitly state that the algorithm utilizes AI or ML techniques. It could be a traditional signal processing or mathematical algorithm.
No.
The device is intended for monitoring cardiac output, not for treating any medical condition or disease.
Yes
The device is intended for "monitoring of cardiac output" and displays various physiological parameters such as Cardiac Output (CO), Stroke Volume (SV), Heart Rate (HR), Systolic and Diastolic Pressure. This collection and display of physiological data fall under the definition of a diagnostic device, as it provides information about the patient's health status.
No
The device description explicitly lists multiple hardware components including an ECOM Endotracheal Tube, ECOM Monitor, ECOM Tube Cable, and a Laptop Computer, in addition to the software algorithm.
Based on the provided text, the ECOM (Endotracheal Cardiac Output Monitoring) System is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: In Vitro Diagnostics are devices intended for use in the collection, preparation, and examination of specimens taken from the human body (such as blood, urine, or tissue) to obtain information for diagnostic or monitoring purposes.
- ECOM System Function: The ECOM System directly monitors physiological parameters within the patient's body (cardiac output, stroke volume, heart rate, blood pressure) using electrodes on an endotracheal tube and an arterial pressure line. It does not analyze specimens taken from the body.
Therefore, the ECOM System falls under the category of a medical device used for physiological monitoring, not an In Vitro Diagnostic device.

Device Description
The ECOM (Endotracheal Cardiac Qutput Monitoring) System consists of an ECOM Endotracheal Tube, which contains the electrodes, an ECOM Monitor, an ECOM Tube Cable, and a Laptop Computer. The ECOM System is used in conjunction with a commercially available arterial pressure (AP) line and 3 surface leads on the patient's chest for R-Wave Detection. The Instructions For Use in Appendix 1 includes pictures of each of these components.
The ECOM System is intended for the continuous monitoring of cardiac output by a specially designed endotracheal tube using the principle of bioimpedance (impedance cardiography). Bioimpedance is based on the principal that all biological tissues. including blood, muscle, bone and fat, have electrical properties. Of these, blood is one of the most electrically conductive. Because arterial blood is pulsatile, changes in blood flow result in changes in electrical conductivity and hence the impedance of the blood to electrical current.
The ECOM System measures impedance by injecting a small alternating electrical current (100kHz, 4.0mA) between a pair of electrodes located on the shaft and cuff of the ECOM Endotracheal Tube. Additional electrodes on the ECOM Endotracheal Tube sense the change of impedance caused by changes of the aortic blood flow.
A proprietary ECOM algorithm is used to calculate ventricular stroke volume (SV) from the impedance and arterial pressure waveforms. The stroke volume is multiplied by the patient's heart rate (HR) to calculate cardiac output (CO) in liters per minute. In addition to these parameters, ECOM displays traces of the impedance waveforms, R-Wave Detection signals, systolic and diastolic arterial pressure.
The ECOM Endotracheal Tube contains seven low profile, flexible electrodes affixed to the cuff and shaft of a Standard Endotracheal Tube. The close proximity of the endotracheal tube balloon cuff in relationship to the ascending aorta provides an optimal location from which to measure impedance changes resulting from aortic blood flow.
The ECOM Endotracheal Tube is provided sterile for single use only. It will be available in 6.0mm to 9.0mm sizes, in 0.5mm increments.
The ECOM Monitor, Laptop Computer, ECOM Tube Cable, Lead Wire, Arterial Pressure Cable. Cord Sets, Power Supply, and Power Conditioner are reusable and provided nonsterile.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
This study, which was the final step of a three-phase clinical development program, was performed to document the performance of Imagyn's ECOM System.
For this study, time matched data for the ECOM System and pulmonary artery catheters were obtained, which provided multiple thermodilution cardiac output measurements.
Imagyn's ECOM System is a new system for the measurement of CO that has been tested in human subjects. The ECOM System provides a continuous measurement of CO derived from impedance electrodes on an endotracheal tube measurements / supported by information from blood pressure derived from arterial line pressure measurement and has been found to be substantially equivalent at estimating cardiac output as are the predicate non/less invasive devices.

6. Device compared to predicate device
The ECOM System is substantially equivalent to four devices, three of which are currently on the market, all of which were cleared through the 510(k) process. The ECOM System shares the same intended use as all four predicate devices - cardiac output monitoring. The ECOM System shares certain technological features of each predicate device and no new safety and effectiveness questions are raised.
The Swan-Ganz catheter predicate device measures cardiac output using the principle of thermodilution. The catheter is introduced in the venous system (typically in the internal jugular vein) and "floated" through the right heart into the pulmonary artery using an airfilled balloon at the distal tip. The ECOM System would allow for the determination of continuous cardiac output without the risks associated with right heart catheterization. Like the BioZ™ predicate device, the ECOM System measures cardiac output by a bioimpedance method, but takes the measurement at a different anatomical site. The only significant difference in the ECOM System and BioZ™ is that the ECOM System
2
measures bio-impedance with electrodes placed in the trachea, whereas the BioZ™ measures impedance with electrodes placed on patient's neck and trunk.
The ABCOM 1™ predicate device, like the ECOM System, uses electrodes placed on a standard endotracheal tube to measure the flow of blood through the patient's aorta using ultrasonic doppler, and thus provides a visual display of cardiac output. While both the ABCOM 1™ and the ECOM System use the same anatomical site, the ABCOM-1™ uses an ultrasonic doppler measuring method rather than the bio-impedance method used by the ECOM System and the BioZTM product.
The Hemosonic predicate device is a transesophageal probe that measures continuous aortic blood flow using ultrasound technology. Conceptually similar to the ECOM System, which is placed in the trachea adjacent to the ascending aorta, the Hemosonic device is placed in the esophagus adjacent to the descending aorta.
In summary, the intended use, patient population, and anatomical site (trachea) of the ECOM System are equivalent to that of the ABCOM 1™, while the energy emitted and received, as well as the electrode design and function are equivalent to that used in the BioZ™ device. The ECOM System also provides continuous cardiac output without the need for right heart catheterization required of the Swan-Ganz flow directed thermodilution catheter. Furthermore, it is conceptually similar to transesophageal ultrasound catheters in that the probe is placed adjacent to the aorta to measure blood flow. Because the ECOM System is based upon well-established technologies (bioimpedance and measuring cardiac output at the trachea) the device does not present any significant new issues of safety or effectiveness.
