Core Engineering & Performance Advantages
Detachable Interlocking Arm for Complete Procedural Control
The defining feature of this **embolic coil pusher** assembly is its innovative detachable interlocking arm mechanism. This design ensures that the embolic coil remains securely anchored to the delivery chassis during transit through highly tortuous neurovascular paths. It gives physicians the critical capability to fully reposition, retract, or rescue the therapeutic coil at any point before final detachment, drastically reducing the clinical risk of coil migration or accidental prolapse.
Engineered 1:1 Pushability and High Kink Resistance
By transitioning smoothly from a high-tensile proximal stainless steel shaft to an ultra-flexible superelastic Nitinol distal core, the pusher ensures exceptional crossability. The continuous centerless taper profile eliminates mechanical step-downs, providing an isotropic 1:1 tactile response back to the operator's hands.
Seamless Radiopaque Tracking and Microcatheter Compatibility
Equipped with micro laser-welded Platinum-Iridium marker bands, our pushers allow for precise micro-positioning under fluoroscopy. The outer high-polymer jacket is engineered for ultra-low friction coefficients, minimizing internal friction within 0.016.5" or 0.021" microcatheters to allow smooth deployment.
Applications
- Intracranial aneurysm embolization systems (mechanical & thermal-assisted detachment platforms)
- Arteriovenous Malformation (AVM) and dural arteriovenous fistula (dAVF) occlusion systems
- Peripheral vascular embolization systems (splenic, hepatic, and renal artery occlusion)
- Custom delivery mandrels for oncology micro-particle and therapeutic payload delivery
