AXS Catalyst 7

Distal Access Catheter

Powerful in your hands.

Control the clot

Improve your confidence in first pass efficacy by engaging the clot with full control using the AXS Catalyst 7 Distal Access Catheter, the only 0.068in catheter designed to TRAP more1 with the fully compatible FlowGate2 Balloon Guide Catheter and Trevo XP ProVue Retriever.

TRAP in action with CAT 7*
Left ICA/MCA occlusion.
Symptoms

A 57 year old male presented to Dr. Timo Krings of the University of Toronto with an occlusion of the left ICA terminus and MCA and an ASPECTS score of 7. The patient had crashed his car after experiencing a sudden onset of right sided weakness, confusion, and aphasia while driving. CTP within 1 hour of symptom onset showed a large mismatch volume with core infarct volume of 72 mL and ischemic penumbra involving almost the entire left MCA territory.

Primary access

Dr. Krings gained primary access via right CFA approximately 2 hours after symptom onset. Initial angiogram showed stagnant left ICA flow consistent with ICA terminus occlusion. He advanced a FlowGate2 Balloon Guide Catheter over a Simmons 2 select catheter into the proximal left ICA and then navigated an AXS Catalyst 7 Distal Access Catheter through a moderately tortuous siphon to the clot over a Trevo Pro 18 Microcatheter and Synchro2 Standard Guidewire.

Clot secured with Trevo
6x25 and controlled with
CAT 7.
Securing the clot

Dr. Krings secured the clot with a Trevo XP ProVue 6x25 Retriever, controlled the proximal clot with CAT 7 and vacuum from the AXS Universal Aspiration Set, and used the TRAP technique to remove the clot while utilizing flow control to protect from distal micro-emboli. He achieved TICI 3 reperfusion of the left ICA and MCA in one pass, 20 minutes after groin puncture. The patient achieved nearly full recovery of right sided strength with mild residual dysphasia, with post-op MRI showing small infarcts in the left basal ganglia and frontal cortex.

The Transitionless
ReinforcementTM advantage

Empowers first past efficacy with consistent FlowGate2 Balloon Guide Catheter compatibility3.

CAT 7 vs. 0.068in reperfusion catheter

Transitionless ReinforcementTM enables improved control while tracking through cervical tortuosity3

Transitionless
Reinforcement

Controlled push transmission while navigating through tight bends.

Conventional
design

Force build-up & jumping when transition points get caught in tortuosity.

Single nitinol coil.

Continuous shift from tight to wide coil pitch without distinct transition points.

Similar distal flexibility to other
0.068in catheters2.

Distal wide pitch coil

More proximal pushability than other
0.068in catheters2.

Proximal tight pitch coil

Quintessential elements of the AXS Catalyst Distal Access Catheter family

A. Smoothly navigate tortuosity
B. Pair confidently with retrievers
C. Stretch resistant

With the edgeless tip.
With a full length PTFE liner.
With a high-strength polymer fiber.
