The summary describes a device that derives central arterial indices from a peripheral waveform using a tonometer and standard blood pressure calibration. It mentions "derived ascending aortic blood pressure waveform" and "central arterial indices," which suggests algorithmic processing of the waveform data, but there is no mention of AI, ML, or related terms like neural networks, deep learning, or training/test sets, which are typically associated with AI/ML technologies in regulatory submissions. The description focuses on the measurement and calculation of physiological parameters rather than learning from data to make predictions or classifications.
No
The device is described as a computerized tool for providing diagnostic information (blood pressure waveform, central arterial indices, Heart Rate Variability, Pulse Wave Velocity), not for treating a condition.
Yes
The device provides a derived ascending aortic blood pressure waveform and central arterial indices (including Heart Rate Variability and Pulse Wave Velocity), which are used to obtain information about a patient's cardiovascular health. This information is used by physicians for diagnostic purposes, particularly when more invasive monitoring is deemed too risky.
No
The device description explicitly states it is used "with a tonometer over a radial artery" and "calibrated with a standard blood pressure cuff measurement," indicating the use of hardware components beyond just software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD definition: In Vitro Diagnostics are medical devices intended for use in vitro for the examination of specimens, including blood and tissue samples, derived from the human body, solely or principally for the purpose of providing information concerning a physiological or pathological state, or a congenital abnormality, or to determine the safety and compatibility with potential recipients, or to monitor therapeutic measures.
- Device function: The SphygmoCor CvMS measures physiological parameters directly from the patient's body (radial artery pressure waveform, heart rate, pulse wave velocity) using a tonometer and blood pressure cuff. It does not analyze specimens in vitro.
- Intended Use: The intended use describes obtaining information related to ascending aortic blood pressure and other central arterial indices directly from the patient, not from analyzing samples outside the body.
Therefore, the SphygmoCor CvMS falls under the category of a non-invasive medical device that measures physiological parameters directly from the patient.

Device Description
The SphygmoCor CvMS device (un-modified device) is a computerized tool for providing a derived ascending aortic blood pressure waveform and a range of central anterial indices. The CvMS is used with a tonometer over the radial artery to capture a pressure waveform which is used to derive central pressure and is calibrated with a standard blood pressure cuff measurement. The CvMS is intended for use on those patients where information related to ascending aortic blood pressure is desired but in the opinion of the physician, the risks of cardiac catheterization procedure or other invasive monitoring may outweigh the benefits. In addition, the CvMS incorporates an option to enable users to measure Heart Rate Variability (HRV) in response to controlled exercises.
The SphygmoCor CvMS with the PWV option (modified device) is a software addition to the SphygmoCor CvMS device (K070795). This software feature provides an additional central arterial indice - Pulse Wave Velocity (PWV).
Description of Modification
The PWV option provides a modular software addition to the SphygmoCor CvMS (K070795). This simple software addition allows Pulse Wave Velocity to be calculated between two sites in the arterial tree (typically carotid-femoral). This is achieved by capturing arterial pressure waveforms (using tonometry) simultaneously with ECG data. The tonometry and ECG capabilities are unchanged from the predicate device.
The PWV software then calculates the time difference (.st) between the two pressure waveforms using the ECG as a timing reference. The PWV is then simply calculated by measuring the distance between the two arteries and then dividing by At.

Dear Mr. Abram:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050. This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, pcrmits your device to proceed to the market.
If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Center for Devices and Radiological Health's (CDRH's) Office of Compliance at (240) 276-0120. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR Part 807.97). For questions regarding postmarket surveillance, please contact CDRH's Office of Surveillance and Biometric's (OSB's) Division of Postmarket Surveillance at 240-276-3474. For questions regarding the reporting of device adverse events (Medical Device Reporting (MDR)), please contact the Division of Surveillance Systems at 240-276-3464. You may obtain other general information on your responsibilities under the Act from the Division of Small Manufacturers, International and Consumer Assistance at its toll-free number (800) 638-2041 or (240) 276-3150 or at its Internet address http://www.fda.gov/cdrh/industry/support/index.html.
