Indications for Use
The CEREPAK™ Uniform, Uniform 3D, Heliform Soft, Heliform XtraSoft, Heliform XL, Heliform XtraSoft XL, Freeform, and Freeform Mini Detachable Coil Systems are indication of intracranial aneurysms, neurovascular abnormalities such as arteriovenous malformations and arterial and arterial and venous embolizations in the peripheral vasculature. The CEREPAK™ Freeform XtraSoft Detachable Coil System is indication of intracranial aneurysms.
Device Story
Platform delivery system for embolic microcoils; used in endovascular procedures to treat hemorrhagic conditions. Components: CEREPAK Detachable Coils (microcoil attached to delivery shaft) and CEREPAK Detacher (mechanical accessory). Physician advances delivery tube with microcoil through microcatheter to target lesion using standard endovascular techniques. Detachment occurs via mechanical finger actuation of Detacher, which translates internal pull wire to release microcoil. Once detached, delivery tube is removed. System enables precise placement of embolic coils to occlude aneurysms or vascular abnormalities. Benefits include minimally invasive treatment of neurovascular lesions.
Clinical Evidence
No clinical data. Evidence consists of bench testing (design verification, mechanical integrity, simulated use, MRI compatibility) and in-vivo porcine animal study. Biocompatibility testing performed per ISO 10993-1.
Technological Characteristics
Microcoils: Platinum/Tungsten, secondary shapes (complex, helical, spherical). Delivery system: Hypotube shaft with Nitinol loop wire and PTFE-coated 304 SS pull wire. Detachment: Mechanical finger-actuated slider. Sterilization: Ethylene Oxide (EO) per ISO 11135-1. Shelf life: 1 year. Connectivity: None.
Indications for Use
Indicated for embolization of intracranial aneurysms, neurovascular abnormalities (arteriovenous malformations, arteriovenous fistulae), and peripheral arterial/venous embolizations. Freeform XtraSoft is indicated for intracranial aneurysms only.

IV. Device CEREPAK™ is a platform delivery system that aids in the delivery of embolic coils (or Description "microcoils") using standard endovascular methods to treat hemorrhagic conditions. It consists of two main components, the CEREPAK™ Detachable Coils, and the CEREPAK™ Detacher. These components will be provided sterile and sold separately. The CEREPAK™ Detachable Coils are comprised of an embolic coil implant (microcoil) attached to a delivery system. The CEREPAK™ Detacher is a mechanical accessory that aids in the detachment of the CEREPAK™ Detachable Coils.
> The delivery system of the CEREPAK™ Detachable Coils consists of a long, thin hypotube (delivery tube) shaft with an attachment interface to secure the microcoil at its distal end until deployment is required. Microcoil designs are based on the microcoils present in the predicate device. The delivery tube is advanced with the microcoil through a compatible microcatheter using standard endovascular techniques until the microcoil is placed at the target lesion.
> The CEREPAK™ Detacher interacts with the delivery system to detach the microcoils. Upon finger actuation, the Detacher translates (slides) a component within the delivery tube that aided in securing the microcoil. This detaches the microcoil from the delivery tube. Once the microcoil is detached at the desired location, the delivery tube can be removed and discarded.
