Intended Use
The Artix AX aspiration catheter is 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. The Artix AX aspiration catheter is intended for use in the peripheral vasculature.
Device Description
The Artix AX is a single-use, over-the-wire catheter used for the minimally invasive treatment of thromboemboli in the peripheral vasculature. The system comprises two catheter lengths, 85 cm and 115 cm, packaged separately. The Artix AX is inserted over a pre-placed guidewire and advanced to the thrombus, which can then be removed via aspiration with the provided 30 mL Large Bore Vacuum Syringe. The Artix MT may also be deployed through the Artix AX to engage thrombus before being retracted through the Artix AX. Additional clot may be removed by aspiration through the Artix AX as necessary. After the procedure is complete, the Artix AX is removed from the patient.
More Information

No
The summary describes a mechanical aspiration catheter and syringe system. There is no mention of software, algorithms, or any technology that would suggest the use of AI or ML. The performance studies focus on mechanical and fluid dynamics properties.

Yes
The device is used for the non-surgical removal of emboli and thrombi from blood vessels in the peripheral vasculature to treat thromboemboli, which is a therapeutic action.

No

The device is an aspiration catheter used for the removal of emboli and thrombi and the injection/aspiration of fluids from blood vessels, which are interventional or therapeutic actions, not diagnostic ones.

No

The device description clearly outlines a physical catheter and syringe, and the performance studies detail testing of physical properties and simulated use with hardware components.

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 used to examine specimens (like blood, urine, or tissue) taken from the human body to provide information for diagnosis, monitoring, or screening.
  • Device Function: The Artix AX aspiration catheter is a physical device used within the body (in the peripheral vasculature) to remove emboli and thrombi, and to inject/aspirate fluids. It does not analyze specimens outside the body.
  • Intended Use: The intended use clearly describes a therapeutic and procedural function within the patient's blood vessels, not the analysis of biological samples.

Therefore, the Artix AX aspiration catheter is a therapeutic medical device, not an In Vitro Diagnostic.

DescriptionThe Artix AX is a single-use, over-the-wire catheter used for the minimally invasive
treatment of thromboemboli in the peripheral vasculature. The system comprises
two catheter lengths, 85 cm and 115 cm, packaged separately.

The Artix AX is inserted over a pre-placed guidewire and advanced to the
thrombus, which can then be removed via aspiration with the provided 30 mL
Large Bore Vacuum Syringe. The Artix MT may also be deployed through the
Artix AX to engage thrombus before being retracted through the Artix AX.
Additional clot may be removed by aspiration through the Artix AX as necessary.
After the procedure is complete, the Artix AX is removed from the patient. |
| Indications for Use | The Artix AX aspiration catheter is 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.
The Artix AX aspiration catheter is intended for use in the peripheral vasculature. |
| Device Modifications | The proposed modifications are to the Triever16 component and include
dimensional and material changes to the catheter and removal of the dilator.

These modifications introduce the Artix AX, a smaller embolectomy catheter used
for aspiration thrombectomy in the peripheral vasculature.

There have been no changes to the Triever20 Fr/20 Curve and the Triever24 Fr
Catheters or the FlowTriever Catheters. |

Comparison of Technological Characteristics with the Predicate Device

The proposed modifications do not change the intended use or principles of operation from the predicate device. The modified and predicate device have a similar design and mainly differ in dimensions and materials.

The Artix AX and Triever16 are both tracked over a pre-placed compatible guidewire. The Artix MT or FlowTriever Catheter can then be deployed through the Artix AX or Triever 16/20/24 Fr catheters respectively to engage and withdraw thrombus. Additional clot can be aspirated through the Artix AX or Triever16 using the provided 30 ml or 60 mL Large Bore Syringe.

Although the predicate and subject devices have different technological characteristics, all leveraged and performed design verification and validation tests confirm that these differences do not raise any new or different questions of safety or effectiveness.

There have been no changes to the Triever20 Fr/20 Curve or the Triever24 Fr Catheters or the FlowTriever Catheters.

Summary of substantial There is no change of intended use or fundamental scientific technology between the equivalence proposed device and predicate device. The Artix AX's indications for use falls within those of the predicate device. K213402: both are indicated for the non-surgical removal of emboli and thrombi from blood vessels and the injection, infusion, and/or aspiration of contrast media and other fluids into or from a blood vessel. Both are intended for use in the peripheral vasculature. The Triever16 is additionally intended for the treatment of pulmonary embolism and for use in treating clot in transit in the right atrium but not in conjunction with FlowTriever Catheters.
