The MicroCATH Neurovascular Catheter Family is a lineup of microcatheters designed to support fine navigation through tortuous cerebral arteries for a range of neurointerventional procedures. This overview summarizes the family's design intent, key characteristics, and where it fits within a typical neurovascular access strategy.
What Is the MicroCATH Neurovascular Catheter Family Designed For?
MicroCATH is engineered to provide the most consistent stiffness transition from tip to tail, a design goal intended to help operators maintain predictable pushability and trackability as the catheter advances through progressively smaller and more tortuous distal vessels. The lineup is designed to support:
- Coil delivery during endovascular aneurysm treatment
- Liquid embolic agent infusion
- Distal neurovascular exploration and diagnostic navigation
This breadth is intended to let a single catheter platform serve multiple procedural roles depending on the clinical scenario and physician preference.
What Design Characteristics Support Tortuous Navigation?
Neurovascular anatomy — particularly beyond the carotid siphon and into the intracranial circulation — is characterized by tight curves, variable vessel caliber, and fragile vessel walls. Microcatheter design for this environment generally emphasizes:
- Consistent stiffness transition — reducing abrupt handling changes along the catheter shaft, which is intended to support smoother advancement through curves
- Torque response — supporting predictable tip control as the catheter is rotated during navigation
- Lubricious outer coating — intended to reduce friction against the vessel wall and adjacent devices during advancement
- Radiopaque markers — supporting visualization of catheter tip position under fluoroscopy
These characteristics are designed to work together to help operators reach distal target sites while managing the mechanical demands of tortuous cerebral anatomy.
How Does MicroCATH Fit Into a Neurointerventional Procedure?
In a typical procedure, a microcatheter is advanced coaxially through a guide catheter or intermediate/distal access catheter that has already been positioned in the proximal cervical or intracranial circulation. The microcatheter is then navigated, often over a neurovascular guidewire, to the specific target — such as an aneurysm sac for coil delivery or a vascular malformation for liquid embolic infusion.
Because MicroCATH spans multiple intended uses, selection among its variants depends on the specific procedure, target vessel size, and the embolic material or device being delivered.

Frequently Asked Questions
What procedures is the MicroCATH family designed to support?
MicroCATH is designed to support coil delivery for aneurysm treatment, liquid embolic agent infusion, and general distal neurovascular exploration, depending on the specific catheter variant selected.
How does a microcatheter differ from a guide catheter?
A guide catheter provides proximal support and access into the cervical or proximal intracranial vasculature, while a microcatheter is a smaller, more flexible device advanced further distally through the guide catheter to reach specific target vessels or lesions.
Is MicroCATH compatible with liquid embolic agents?
The MicroCATH family includes variants designed for liquid embolic infusion. Compatibility with specific embolic agents should always be confirmed against the official Instructions for Use before use.
