Modified Simmons Catheter

Neurointerventions with improved success

Invention Summary:

The global neurovascular catheter market size was valued at USD 2.88 billion in 2020 and is expected to expand at a compound annual growth rate of 6.7% from 2021 to 2028. Neurointerventionalists, interventional radiologists, cardiologists, and vascular surgeons often can have difficulties using the commonly used Simmons catheter or any other double curve or a diagnostic angiography catheter for endovascular interventions for neurological/ peripheral vascular or cardiac disorders. This catheter tends to herniate back into its parent vessel (arch of the aorta or descending aorta or their branches) more so, in tortuous vessels rather than advancing forwards along the artery of interest. 

Rutgers researchers are near to completing the designing of a modified Simmons/ other double curve/ diagnostic angiography catheter to perform brain/ cardiac or peripheral vascular interventions. The new catheter will be anchored to allow it to be stable and thereby prevent it from herniating. Once the catheter is stable, surgeons can advance the guidewire distally to gain purchase to the distal artery of interest. Once the internal carotid artery/other arteries of interest are accessed and supported, the anchor can be removed, and the catheter can be advanced for interventions as intended. This is more helpful as the radial approach is becoming more commonly used for neurointerventions. This catheter can make access to the left vertebral artery through the right radial artery feasible. Balloon occlusion tests can be performed without needing a guide and a micro balloon catheter making the procedure more economical. 

Market Applications:

  • Endovascular procedures.
  • Mechanical thrombectomy for stroke.
  • Aneurysm coiling.
  • Arteriovenous malformations embolizations.
  • Balloon test occlusion.


  • Stable placement of the catheter in the tortuous blood vessels.
  • Neurointerventions with improved success.
  • Less time to perform the interventions.
  • Safer procedures with less adverse events and morbidity to the patients.
