Patent ID: 7731705

Claim:
An eluting coil for deployment within a body of a patient, comprising: a resilient elongate element including a flattened ribbon-like configuration, a first surface, a second surface, a pre-stressed non-coiled configuration in a restrained state that ensures contact between the first surface and the second surface in adjacent sections of the elongate element when the elongate element is in a coiled configuration in a relaxed state with the first surface disposed adjacent the second surface in an overlapped portion of the elongate element; at least one dissolvable agent reservoir disposed on the elongate element in a position that is contained from an outside portion of the eluting coil when the elongate element is in a relaxed coiled configuration; and structure on the first surface configured to form at least one conduit between the first and second surfaces of adjacent sections of the elongate element in the coiled configuration, the at least one conduit including a pre-determined cross section and being in fluid communication between the contained dissolvable agent reservoir and an outside portion of the coiled configuration of the resilient elongate element in the relaxed state.
