Methods and apparatus are provided for delivering drugs or gene therapy within a patient's vessel (V). In a preferred embodiment, the apparatus (20) comprises a material eluting a bioactive substance (B) held in place within the patient's vessel (V) by an anchor (24). The anchor (24) and eluting material (22) are sized and/or collapsible from a delivery configuration, in which the anchor (24) and material (22) may be delivered into the patient's vasculature within a delivery sheath, to a deployed configuration, wherein the anchor (24) engages an interior wall of the patient's vessel (V). The eluting material (22) may elute recombinant genes, drugs, or any other bioactive substance (B). |
