The instrument consists of a tube (6) with a valve and a needle that can be removed and replaced by a feeder (19) to deliver a filament (38) into the aneurism pouch (4). The proximal end of the filament is retained so that it can be withdrawn after a set period of time, and the filament itself can be hollow and have holes along it for injecting a coagulant substance. In variants the filament can be made from a material with a shape memory effect, a thrombogenic and bioresorbable substance, a radio-opaque wire, or one that can be used to pass an electric current through for electrocoagulation. |
