An occlusion device (10) includes a cannula (24), a dilator tip (20) fixed to the cannula and a frame member formed of an occlusion member (28) and a sleeve (30). The occlusion member (28) is covered with occlusion material (26). The cannula (24) is in the form of a tube having a lumen (25) passing therethrough. The dilator tip (20) also has a lumen therethrough and a valve (32). The arrangement is such that the occluder (10) can be delivered by an over the wire method using a guide wire, whereupon the cannula and dilator tip remain in the patient as part of the occluder assembly (10). |
