Designing minimally invasive devices for neurovascular intervention can be extremely challenging. The devices must be small and flexible enough to carefully navigate the winding, delicate anatomy of the tiny blood vessels that run through the head and neck, while being sophisticated enough to complete their function once they arrive at the target site.
Removing thrombus following stroke has been recognised as a important means of improving patient outcomes. Removing the clot, typically involves the use of aspiration with or without thrombus ‘stentreiver’ devices. Aran Biomedical can offer unique design solutions for these types of devices, through development of nitinol braids and/ or thin elastomeric coatings.
Vascular plugs or occlusion devices are widely used to selectively occlude blood vessels across the vasculature.
Filters and porous implants can be designed for embolic protection. Typical designs feature either, a braid with a constrained end, or a braided, laser cut or wire wound Nitinol frame, with an integrated, porous, elastomeric film.
Wide Neck Aneurysms
Covered or uncovered braided solutions by Aran Biomedical, offer a compelling and versatile option for the treatment of aneurysms. High density, uncoated braids of micro fine wire are used ‘flow diverter’ stents. Alternatively by coating the braid, an impermeable barrier is achieved without the need for as many wire ends. Ultra thin elastomeric coatings conform with the braid during crimping and deployment, and offer exceptional flexibility for tortuous anatomy.
