Abstract
A vascular filter system and method are disclosed. In one embodiment, the filter system comprises a dispensing needle releasably attached to a filter dispenser which stores a length of filter wire. The filter wire dispenser has a guide tube which guides the filter wire into the needle and then into a vein during surgical implantation. The filter wire is configured to coil into a predetermined shape as it is deployed from the needle. The shape of the filter wire captures blood clots in the blood stream. The filter wire is configured with a perforated section and a non-perforated section. Perforations are in fluid communication with an inner hollow lumen in the filter wire. A hub assembly attaches to an end of the filter wire that is external to the body to provide a port into the lumen for application of medication into the lumen and out the perforations.
