No
The device description focuses on electronic simulation of clotting times using fixed circuitry, not adaptive or learning algorithms. There is no mention of AI, ML, or related concepts in the summary.
No
The device is an in vitro diagnostic (IVD) quality control tool used to verify the proper functioning of coagulation instruments, not to treat or diagnose patients.
Yes
The "Intended Use / Indications for Use" states, "The HEMOCHRON® Electronic System Verification Tube is intended for in vitro diagnostic use in performing a quantitative electronic detection system verification of HEMOCHRON® Coagulation Instruments." This clearly indicates its use in diagnostics, specifically for verifying the accuracy of diagnostic instruments.
No
The device description explicitly states it is a "plastic tube with battery operated electronic circuitry," indicating it is a hardware device, not software-only.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Explicit Statement: The "Intended Use / Indications for Use" section clearly states: "The HEMOCHRON® Electronic System Verification Tube is intended for in vitro diagnostic use..."
- Purpose: The device is used to verify the functionality of HEMOCHRON® Coagulation Instruments, which are themselves IVD devices used to perform diagnostic tests on patient samples (in vitro). The verification tube ensures the accuracy and reliability of these diagnostic instruments.
- Quality Control: The description highlights that the comparison of the displayed clotting time with the ESVT clotting time is a "quality control test of the functionality of the test well and test detector." Quality control materials and procedures for diagnostic instruments are considered part of the IVD process.
Therefore, based on the provided text, the HEMOCHRON® Electronic System Verification Tube is an IVD.

Device Description
The Electronic System Verification Tube (ESVT) performs Electronic Quality Control on all marketed HEMOCHRON® tube instruments HEMOCHRON® models 8000, 401, 801 and the new HEMOCHRON® RESPONSE (K983475) currently under FDA review. The device is a plastic tube with battery operated electronic circuitry that electronically simulate test initiation and clot detection using the same principles employed in a clotting time assay. Once started and placed in the Hemochron test well, the ESVT electronically simulates the operation of a 100, 300 and 500 second clotting time. The comparison of the displayed Hemochron clotting time with the ESVT clotting time is a quality control test of the functionality of the test well and test detector.

Statement of Intended Use
The HEMOCHRON® Electronic System Verification Tube is intended for in vitro diagnostic use in performing a quantitative electronic detection system verification of HEMOCHRON® Coagulation Instruments. The Electronic System Verification Tube electronically simulates test initiation and clot detection in the same manner as patient assay end points are recorded.
Summary of Technological Characteristics and Performance Data
The HEMOCHRON® ESVT is an improvement to the Electronic Quality Control designed to perform the same three (3) testing time ranges as the predicate three (3) separate electronic verification tubes. The upgrade provides the end user with additional quality features to assure the HEMOCHRON® instrument is operating properly. The ESVT is designed to check the timing capability of the HEMOCHRON instrument, as well as, verifying well rotation.
The previously approved test ranges are established in (K940957/S1).

Dear Mr. Clay:
We have reviewed your Section 510(k) notification of intent to market the device referenced above and we 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). 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 (Premarket Approval), 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 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.

Under the Clinical Laboratory Improvement Amendments of 1988 (CLIA-88), this device may require a CLIA complexity categorization. To determine if it does, you should contact the Centers for Disease Control and Prevention (CDC) at (770) 488-7655.
This letter will allow you to begin marketing your device as described in your 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, permits your device to proceed to the market.
If you desire specific advice for your device on our labeling regulation (21 CFR Part 801 and additionally 809.10 for in vitro diagnostic devices), please contact the Office of Compliance at (301) 594-4588. Additionally, for questions on the promotion and advertising of your device, please contact the Office of Compliance at (301) 594-4639.
