Abstract:
1. An interventional transvascular delivery system for delivering or relocating an implant in the cardiovascular system of a patient, the system comprising: an elongated tubular portion defining a lumen and having an internal diameter; a releasing element slideably moveable in the lumen of said elongated tubular portion comprising a tubular elongated member comprising a distal end, and a lumen having an internal diameter for releasing said implant from the delivery system; a core wire slidably moveable in the lumen of the tubular elongated member comprising a distal end; an attachment device positioned at the distal end of the core wire and comprising an attachment surface and a diameter; and an implant including a tip having a target surface, said tip positioned at the proximal end of the implant and having a diameter larger than the internal diameter of the lumen of the tubular elongate member; wherein the attachment surface reversibly binds to the target surface of said implant for delivering and relocating said implant in said patient, wherein both the attachment surface of the attachment device and the target surface of the implant are substantially spherical, and the combined diameter of the attachment device and the implant tip is greater than the internal diameter of the elongated tubular portion.
