Villepinte, France, April 24th, 2019 - Guerbet (FR0000032526 GBT), a global specialist in contrast agents and solutions for medical imaging, announces the upcoming European launch of SeQure® and DraKon™, two novel microcatheters for peripheral embolization procedures. SeQure® and DraKon™ microcatheters received the CE mark 7436GB410190416 on April 16th, 2019 for the delivery of intra-arterial therapy and embolic materials into all peripheral vessels.

The SeQure® microcatheter is an innovative reflux control microcatheter that uses flow dynamics to create a fluid barrier designed to deliver more treatment to the target vessel1 and reduce the risk of non-target embolization2,3, for less potential damage to surrounding tissue. It consists of side slits which size has been specifically designed to allow the outflow of contrast media, creating a fluid barrier around the microcatheter to reduce microspheres reflux and assist delivery to the target vessel.

Standard microcatheter, positioned in the artery irrigating the tumor: the embolization microspheres travel not only downstream (desired effect) but also upstream (undesired effect), in an artery irrigating healthy tissues that need to be preserved.


Reflux control microcatheter: the reflux control technology sends all the embolization microspheres downstream into the area to be treated. The healthy tissue continues to be irrigated by blood free of microspheres.


The DraKon™ peripheral microcatheter is the same as SeQure® but without the side slits. It has been designed to optimize pushability, flexibility and torqueability for improved trackability and highest performance standards4,5,6.

Both the SeQure® and DraKon™ technologies offer interventional radiologists enhanced navigation capabilities to enable access to difficult anatomies and reach farther.

"Guerbet is expanding its interventional portfolio with new solutions for interventionalists, to further enhance and secure their embolization cases. This new range of microcatheters will allow us to help interventional radiology community deliver a higher quality of care during image-guided embolization procedures," commented Thomas Bonnefont, VP Commercial Interventional Imaging. 

Guerbet obtained both microcatheters as part of their acquisition of Israeli company Accurate Medical Therapeutics announced in January 2018.

The SeQure® and DraKon™ microcatheters received FDA clearance on January 26, 2018 and are commercialized on the US market. They are also registered in Hong Kong, in New Zealand and in Thailand. The registration plan includes Australia, China, India, Japan, Korea, Singapore and Vietnam within the next 2 years.
