Intended Use
The EkoSonic Endovascular Device with Control Unit 4.0 is indicated for the: - Ultrasound facilitated, controlled and selective infusion of physician-specified fluids, including thrombolytics, into the vasculature for the treatment of pulmonary embolism. - Infusion of solutions into the pulmonary arteries. - Controlled and selective infusion of physician-specified fluids, including thrombolytics, into the peripheral vasculature.
Device Description
The EkoSonic Endovascular Device with CU 4.0 consists of an EkoSonic Endovascular Device and the Control System 4.0 (Control Unit 4.0 and Connector Interface Cables). The EkoSonic Endovascular Device consists of a disposable infusion catheter with removable ultrasound core. The infusion catheter contains multiple side holes distributed over the length of the treatment zone. The ultrasound core contains up to 30 ultrasound elements, evenly spaced over the treatment zone. Thermal sensors in the treatment zone monitor catheter temperature. The Control System 4.0 generates and controls the delivery of radiofrequency energy to the ultrasound core while monitoring and controlling the temperature of the treatment zone. It is the modifications to the Control System 4.0 that are the subject of this submission.
More Information

No reference devices were used in this submission.

No
The document explicitly states "Mentions AI, DNN, or ML: Not Found" and the device description focuses on hardware and control system modifications without mentioning AI/ML functionalities.

Yes
The device is indicated for the treatment of pulmonary embolism, which is a therapeutic purpose.

No

Explanation: The device is indicated for therapy (infusion of fluids and thrombolytics) and not for diagnosing a condition.

No

The device description explicitly details hardware components like a disposable infusion catheter, ultrasound core with elements, thermal sensors, and a Control System 4.0 that generates and controls radiofrequency energy. The submission also mentions hardware testing.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections. They are used to provide information for diagnosis, monitoring, or screening.
  • Device Function: The EkoSonic Endovascular Device with Control Unit 4.0 is an invasive device that is inserted into the vasculature. Its function is to facilitate the infusion of fluids (like thrombolytics) directly into the blood vessels using ultrasound energy.
  • Lack of Sample Analysis: The description does not mention any analysis of samples taken from the body. The device acts directly within the patient's circulatory system.

Therefore, the device's intended use and mechanism of action clearly place it outside the scope of in vitro diagnostics. It is an in vivo device used for therapeutic purposes.

Dear Mr. Hornsey:

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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to 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); medical device reporting of medical device-related adverse events) (21 CFR 803) for

devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/CombinationProducts/GuidanceRegulatoryInformation/ucm597488.html; good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to http://www.fda.gov/MedicalDevices/Safety/ReportaProblem/default.htm.
