Design Overview

See image in full size

Based on DraKon® microcatheter technology, SeQure® optimizes flexibility4, pushability and torqueability5 for improved trackability 4,5,6.

  1. Distal marker enhances tip visualization & Proximal marker enables precise positioning in the target vessels.
  2.  Reduces microspheres reflux and associated nontarget embolization.
  3.  Specifically designed tip using flow dynamics principles.
  4.  Radially filtered contrast media creates a fluid barrier around the microcatheter.
  5.  Specifically configured for each size of microcatheter eliminating vessel size limitation.

Secure Embolics - Reduces Nontarget Embolization3

Sequre® mechanism-of-action



Improve Embolization​

Allows Increased And Targeted Delivery Of Embolic Material7

No Learning Curve

No moving parts and no activation required

  • Does not cause artery spasm3
  • Maintains normal blood flow

Beads volume collected until reflux observed (data from vitro investigations) 7


  • No compromise on microcatheter performance & delivery
  • Same embolization endpoint

SeQure® - Reflux Control Microcatheter

Embolization of hepatic artery with SEQURE® microcatheter in swine animal model using 100 µm microspheres

Physicians talk


Florian Wolf (Vienna, Austria)

"No more blush of the prostate arteries, all vessels surrounded are still very patent so SeQure® made an excellent job in those small and tortuous vessels."

Florian Wolf (Vienna, Austria)

"Not an easy embolization, very tortuous vessels and SeQure® microcatheter did a great job in this case. After embolization, all vessels are patent and only the tumor feeder is embolized, and there is no more tumor blush."

Thierry de Baere (Villejuif, France)

"Nice stasis inside the target vessels and full patency of side vessel branches at final angiogram so they were well protected."

Tim Bryant (Southampton, United Kingdom)

"Static flow in the treated vessels (Segment 5) but still good perfusion in Segment 8 branch so SeQure® worked well from that perspective."
