The description focuses on a physical instrument with a Doppler sensor and a transceiver box, with no mention of AI/ML algorithms for data processing or interpretation.
No
The device is intended for detection and temporary occlusion, which are diagnostic and surgical assistance functions, not therapeutic.
No
The Cstat is described as a device for "detection and temporary occlusion of blood vessels during vascular surgical procedures." While it uses a Doppler sensor for blood flow sensing (a diagnostic method), its primary stated intended use includes an interventional component ("temporary occlusion"). The "diagnostic" aspect of sensing blood vessels appears to be in service of the interventional use rather than for standalone diagnostic purposes like disease diagnosis or patient monitoring. Moreover, the performance studies primarily focus on safety and reliable operation in accordance with instructions for use, rather than diagnostic performance metrics (e.g., sensitivity, specificity for a particular condition).
No
The device description explicitly states it is a "ring-handled instrument with integrated Doppler sensor" and is "manufactured from nylon and polycarbonate," indicating it is a physical hardware device, not software only.
Based on the provided information, the Cstat is not an IVD (In Vitro Diagnostic) device.
Here's why:
- Intended Use: The intended use is for "detection and temporary occlusion of blood vessels during vascular surgical procedures." This describes a device used in vivo (within the living body) during a surgical procedure, not a device used in vitro (outside the body) to examine specimens like blood, urine, or tissue.
- Device Description: The description details a surgical instrument with an integrated Doppler sensor for sensing blood flow in vivo.
- Lack of IVD Characteristics: There is no mention of analyzing biological specimens, reagents, or any of the typical components or processes associated with IVD devices.
Therefore, the Cstat is a surgical instrument with a diagnostic component (the Doppler sensor) used during a surgical procedure, not an IVD.

A description of the device that is the subject of the 510(k), including 4. explanation of how the device functions, basic scientific concepts, significant physical and performance characteristics (design, material, physical properties):
The Cstat is a ring-handled instrument with integrated Doppler sensor, which allows for blood flow sensing of blood vessels by connecting to a commercially available portable transceiver box. The Cstat is manufactured from nylon and polycarbonate.
ഗ് Statement of intended use:
The Cstat is intended for detection and temporary occlusion of blood vessels.
6. Statement of how the technological characteristics of the device compare to those of the predicate or legally marketed device.
The Cstat and the predicate VCS-A Clamp and Transvaginal Doppler Probe detect blood flow of blood vessels using an 8 MHz pulsed-wave Doppler sensor. The Doppler crystals in all three devices are located at the distal end to allow for forward detection of blood flow.
The Cstat and the predicate VCS-A Clamp are intended to temporarily occlude blood vessels. The Transvaginal Doppler Probe is not intended to occlude blood vessels.
The Cstat and the predicate Medical Designs Hand Drill are each constructed of glass-filled nylon.
7. Brief summary of nonclinical tests and results:
The Cstat has been designed and tested to comply with the requirements of IEC 60601-1 for electrical and thermal safety. Acoustic output power measurements were performed in accordance with the FDA Guidance document Information for Manufacturers Seeking Marketing Clearance of Diagnostic Ultrasound Systems and Transducers. Test results indicate reliable performance when the device is used in accordance with the Instructions for Use.
The Cstat does not raise new issues of safety, effectiveness, or performance.

Dear Ms. Roberts:
We have reviewed your Section 510(k) premarket 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.
This determination of substantial equivalence applies to the following transducers intended for use with the Vascular Technology, Inc. Doppler Transceiver, 8 MHz Selectable Channel, and Part number 108900, as described in your premarket notification:

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 (OS) 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 determination of substantial equivalence is granted on the condition that prior to shipping the first device, you submit a post-clearance special report. This report should contain complete information, including acoustic output measurements based on production line devices, requested in Appendix G. (enclosed) of the Center's September 30, 1997 "Information for Manufacturers Seeking Marketing Clearance of Diagnostic Ultrasound Systems and Transducers." If the special report is incomplete or contains unacceptable values (e.g., acoustic output greater than approved levels), then the 510(k) clearance may not apply to the production units which as a result may be considered adulterated or misbranded.
The special report should reference the manufacturer's 510(k) number. It should be clearly and prominently marked "ADD-TO-FILE" and should be submitted in duplicate to:
Food and Drug Administration Center for Devices and Radiological Health Document Mail Center (HFZ-401) 9200 Corporate Boulevard Rockville, Maryland 20850
This letter will allow you to begin marketing your device as described in your 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 market.
