The polymer core expands when exposed to water, effectively increasing the packing density, and achieving compact embolization, effectively reducing the long-term recurrence rate. Comparing with bare metal coils, Perfiller of the same length has a lower metal occupancy rate, a softer coil, and improved efficacy and safety during use. Before expansion Bare metal coil Perfiller ® Anti-winding wire Polymer core After expansion The expansion of the polymer core can effectively increase the stability of the coil and avoid the compression of the packed coil under the impact of blood flow, thereby ensuring long-term effective sealing of the aneurysm neck, eliminating dog-ear remnant and effectively reducing the recurrence rate. Minimum loop diameter is 1mm and a wide range of small size coils provide more options for small aneurysms as finishing coils. The new delivery system has greater pushability and crossability. The torque response and transmission of the pusher are improved. The delivery process is easier and smoother.

This product is indicated for the endovascular embolization of intracranial aneurysms and other neurovascular abnormalities such as arteriovenous malformations and arteriovenous fistulae.
