Our mission is to provide the best thrombectomy system to health care professionals.
NEXT GENERATION OF CATHETERS
Anaconda Biomed S.L. is a Barcelona based medical device start-up co-founded by Dr. Marc Ribo and Dr. Ofir Arad. The company is developing the next generation of catheters to perform safely and efficiently mechanical thrombectomies.
Stroke is the first cause of permanent disability in the world. The burden for the national health systems can be quantified in billions of dollars.
ANA - Advanced Neurovascular Access -
The ANA is designed for its use in the anterior and posterior neurovascular vessels, such as the Internal Carotid Artery (ICA), the M1 and M2 segments of the middle cerebral artery, the basilar, the posterior cerebral and the vertebral arteries.
Description: The ANA is comprised of two coaxial catheters (Delivery catheter and Funnel catheter) made from variable stiffness sections to be used in conjunction with a Stent Retriever. The funnel catheter is comprised by a radiopaque Nitinol braid covered with a Silicone coating to provide local flow restriction. The delivery catheter has a hydrophilic coating to reduce friction during use and a radiopaque marker on the distal end. Both catheters have a Luer hub on the proximal end. The device is supplied pre-loaded in an insertion tool.
A.- DISTAL FLOW RESTRICTION
(Versus a traditional Balloon Guiding Catheter)
1.- The Clot is dragged down for a shorter distance reducing the risk of rolling out and fragmentation.
2.- Aspiraton is greatly improve as colateral flow is almost nil.
3.- Less territory is exposed to ischemia.
B.- STRONGEST SUCTION FORCE
1.- Suction (removal/retention force applied over the clot) is a matter of force not of flow

Suction Force vs Flow – Published Paper
2- Once vacuum is achieved (from 5s on)
3- Depends on radius at 2nd power
4- The bigger the distal end of the catheter, the stronger the force applied over the Clot.
C.- SECURE RETRIEVAL
1.- The nitinol braided funnel will adjust to the artery diameter up to 5mm limiting “shaving” and fragmentation.
2.- The combination of aspiration and stent retrievers is currently the most reliable technic.
3.- Its covered structure will protect it from the flow further reducing potential fragmentation.
D.- SAFE EXITS
1.- The combination of the covered funnel and the stent retriever will avoid any risk of “roll-out”.
2.- The same combination will avoid distal emboli when entering the Guiding Catheter.
3.- In addition, aspiration is applied during the all extraction path.
