The Ekosonic Mach 4 Endovascular Device by Btg International was cleared through the FDA 510k pathway on May 21, 2014. It is a Class 2 medical device under product code QEY.

What It Is

The Ekosonic Mach 4 Endovascular Device is a specialized tool designed for the mechanical removal of thrombi from venous systems. It operates by using ultrasound-assisted catheter-directed thrombolysis, which enhances the penetration of thrombolytic agents into the clot, facilitating its dissolution. This device is particularly useful in cases where rapid clot resolution is necessary to restore venous flow and prevent complications.

FDA-Cleared Indications

  • Used for ultrasound-assisted catheter-directed thrombolysis in the treatment of venous thromboembolism.
  • Intended to facilitate the infusion and penetration of thrombolytic medication into venous thrombi.
  • Used in the venous system under fluoroscopic guidance by appropriately trained clinicians.

Clinical Applications

  • Catheter-directed thrombolysis for selected acute deep vein thrombosis.
  • Ultrasound-assisted thrombolysis for selected pulmonary embolism cases.
  • Treatment of venous thromboembolism when expedited clot treatment is clinically appropriate.
  • Use in interventional radiology or vascular surgery procedures with concomitant thrombolytic medication.

Reported off-label uses

  • Treatment of thrombosed dialysis grafts or fistulas may be performed with ultrasound-assisted thrombolysis systems, but the specific indication depends on the device labeling and procedure.
  • Use in other venous thromboses outside the cleared indication may be reported in clinical practice, but requires clinician judgment and institutional oversight.

Off-label use: these uses are reported in practice or the literature but are not part of the FDA-cleared indications. Physicians may use a cleared device off-label based on their medical judgment; the manufacturer may not promote off-label uses.

Practical Considerations

  • The catheter size and treatment length must match the affected vessel and the extent of thrombus.
  • The system is used with an appropriate thrombolytic agent; medication selection, dose and infusion duration are determined by the treating clinician.
  • Placement and treatment require fluoroscopic imaging, sterile technique and clinicians trained in catheter-directed thrombolysis.
  • Contraindications and precautions include factors that increase bleeding risk, contraindications to thrombolytic medication, and unsuitable vascular anatomy.
  • MRI safety depends on the specific device components and whether they remain in or near the patient; the applicable FDA labeling and manufacturer MRI conditions should be checked before scanning.
