    Abstract: A system and method for localized delivery of a therapeutic or diagnostic agent within a vessel is provided. The system and method provide for adjustability of the length of the treatment area and for reducing of pressure within the treatment area. A catheter system includes an inner elongated element, an outer elongated element positioned coaxially with respect to the inner elongated element, and a blood-release element at a distal end of the inner elongated element. A proximal occlusion element is positioned at the distal end of the outer elongated element, proximal to an outlet port. A distal occlusion element is positioned at a distal end of the inner elongated element. The distal end of the inner elongated element is distal to and movable with respect to the outer elongated element distal end.

    Abstract: Devices and methods for treating an aneurysm include a single unit having an access element and an occlusion element, the access element providing access to the aneurysm for introducing treatment objects such as coils therethrough while the occlusion element blocks the treatment objects from protruding into the vessel. The access element is an elongated element having an access lumen for direct introduction of coils or for introduction of coils via a microcatheter. The occlusion element is a balloon or an elongated element for introduction of blocking objects such as coils therethrough. In embodiments of the present invention, a distal end of the access element is preshaped at an angle to a longitudinal axis of the device, wherein upon introduction of the device into the vessel, the access element is aligned with the longitudinal axis and at placement of the device adjacent the aneurysm, the access element assumes its pre-shaped configuration.
