BACKGROUND AND PURPOSE: The embolization of aneurysms with hydrogel filaments
allow postprocedural CT and MR imaging studies without artifacts. We compared the …

BACKGROUND AND PURPOSE: A report directly comparing platinum coils, Matrix coils,
and Hydro Coil s in a single animal model does not currently exist. We evaluated and …

This study introduces a new, hybrid embolic device that in addition to offering all the
important attributes of existing detachable platinum coils also shows an enhanced ability to …

Purpose The purpose of the study was to compare the performance of second-generation
embolic devices with that of platinum coils in experimental aneurysms. Methods …

BACKGROUND AND PURPOSE: In the treatment of cerebral aneurysms, platinum coils
often fail to elicit a fibrotic response. We tested the hypothesis that a new, collagen-based …

BACKGROUND AND PURPOSE: Beam-hardening artifacts in CTA can be greatly reduced
by using metal-free coils for aneurysm embolization. We compared the embolic masses and …

Angiographic and histologic results of hydrogel-coated (HydroCoil®) and platinum coil-
treated canine sidewall, canine bifurcation, and rabbit elastase aneurysms (2–52 weeks …

Object. A new embolic agent, bioabsorbable polymeric material (BPM), was incorporated
into Guglielmi detachable coils (GDCs) to improve long-term anatomical results in the …

Background and Purpose—The durability of aneurysm coil embolization is thought to
depend on packing density. The expansile property of hydrogel coating on coils increases …

OBJECTIVE: HydroCoil (MicroVention, Aliso Viejo, CA), a hydrogel-platinum coil hybrid
device, is one of various efforts to overcome delayed recanalization of coiled intracranial …
