Intended Use
Triever Catheters are indicated for: - The non-surgical removal of emboli and thrombi from blood vessels. - Injection, infusion, and/or aspiration of contrast media and other fluids into or from a blood vessel. Triever Catheters are intended for use in the peripheral vasculature and for the treatment of pulmonary embolism. Triever Catheters are also intended for use in transit in the right atrium but not in conjunction with FlowTriever Catheters.
Device Description
The FlowTriever Retrieval/Aspiration System is a single-use over-the-wire catheter-based system for the minimally invasive treatment of thromboemboli in the peripheral vasculature and for the treatment of pulmonary embolism. The system is comprised of two main components packaged separately: Triever Catheters (available in 3 sizes: 16, 20, and 24 Fr) FlowTriever Catheters (available in 4 sizes: 6-10 mm, 11-14 mm, 15-18 mm, and 19-25 mm) The FlowTriever Catheter is inserted through the Triever Catheter and advanced to the thrombus. Self-expanding wireform disks are deployed to engage thrombus by retracting the outer delivery catheter. The FlowTriever Catheter is retracted into the Triever Catheter to capture the targeted thrombus. Additional clot may be removed by aspiration with the provided 60 cc VacLok Vacuum syringe. After the procedure is complete, the Triever Catheter and FlowTriever Catheter are removed from the patient.
More Information

Not Found

No
The summary describes a mechanical catheter-based system for thrombus removal and fluid management. There is no mention of AI, ML, image processing, or any software-driven decision-making or analysis.

Yes.
The device is intended for the non-surgical removal of emboli and thrombi from blood vessels, which directly treats a medical condition.

No

The device is described as a system for the "non-surgical removal of emboli and thrombi" and "treatment" of thromboemboli, indicating a therapeutic rather than diagnostic purpose.

No

The device description clearly outlines a catheter-based system with physical components (catheters, syringe, wireform disks) used for mechanical removal of thrombi, indicating it is a hardware medical device, not software-only.

No, 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, tissue, and urine, derived from the human body, solely or principally for the purpose of providing information concerning a physiological state, state of health, or disease or congenital abnormality.
  • Device Description and Intended Use: The provided text clearly describes a system of catheters used for the physical removal of emboli and thrombi from blood vessels within the patient's body. It also mentions the injection, infusion, and aspiration of fluids into or from a blood vessel. These are all in vivo procedures, meaning they are performed directly on a living organism.
  • Lack of Specimen Examination: There is no mention of the device being used to examine specimens outside of the body.

Therefore, based on the provided information, the Triever Catheters and the FlowTriever Retrieval/Aspiration System are not IVDs. They are interventional medical devices used for therapeutic procedures within the body.

Dear Ms. Nguyen:

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.

Predicate deviceTriever Catheters (K202345)
DescriptionThe FlowTriever Retrieval/Aspiration System is a single-use over-the-wire
catheter-based system for the minimally invasive treatment of thromboemboli in
the peripheral vasculature and for the treatment of pulmonary embolism. The
system is comprised of two main components packaged separately:
Triever Catheters (available in 3 sizes: 16, 20, and 24 Fr) FlowTriever Catheters (available in 4 sizes: 6-10 mm, 11-14 mm, 15-18 mm, and 19-25 mm) The FlowTriever Catheter is inserted through the Triever Catheter and advanced
to the thrombus. Self-expanding wireform disks are deployed to engage thrombus
by retracting the outer delivery catheter. The FlowTriever Catheter is retracted
into the Triever Catheter to capture the targeted thrombus. Additional clot may be
removed by aspiration with the provided 60 cc VacLok Vacuum syringe. After the
procedure is complete, the Triever Catheter and FlowTriever Catheter are
removed from the patient.
Indications for UseTriever Catheters are indicated for: The non-surgical removal of emboli and thrombi from blood vessels. Injection, infusion, and/or aspiration of contrast media and other fluids into or from a blood vessel. Triever Catheters are intended for use in the peripheral vasculature and for the treatment of pulmonary embolism.
Triever Catheters are also intended for use in treating clot in transit in the right atrium but not in conjunction with FlowTriever Catheters.
Device modificationsThis submission added a warning to the Instruction for Use in patients with severe
pulmonary hypertension.
Summary of
substantial equivalenceThere is no change of intended use or fundamental scientific technology between
the proposed and predicate device. Triever Catheters have the same indication for
use as the predicate, K202345.

Animal testing was not required for the determination of substantial equivalence.

Clinical testing was not required for the determination of substantial equivalence.

Conclusion
The information provided demonstrates that including a warning for use in patients
with severe pulmonary hypertension in the Instructions for Use does not raise new
or different questions of safety and effectiveness. It can be concluded that Triever
Catheters with the modified labeling is substantially equivalent to the predicate
device. |
