An atraumatic vessel occlusive system includes a flexible tubular member with an infusion lumen, a vessel occluder mounted at the distal end of the tubular member, and a pressure sensor located within a chamber defined by the occluder. The occluder has a braided construct provided with a fluid impermeable membrane over its proximal portion and a fluid permeable covering over its distal portion. The pressure sensor is adapted to sense pressure within the vessel through the fluid permeable membrane without being subject to the effects of turbulent flow at the exit of the infusion lumen. The accurately sensed pressure can be used to determine a dwell time for the occluder.

Atraumatic occlusive system with compartment for measurement of vascular pressure change

Methods are provided for delivering a treatment therapy to treat an organ diagnosed with a disease state. The methods include delivering a first therapeutic agent into systemic circulation at a first flow rate, and delivering a second therapeutic agent directly into a vessel feeding the organ at a higher second flow rate than the first flow rate in a manner that prevents the second treatment agent from circulating systemically.

Dual pathway therapeutic agent delivery

A treatment system includes a dual lumen catheter system. The first lumen is open to systemic circulation. The second lumen is open to a target delivery location. In an embodiment, a pressure-control element is provided that includes an expanded configuration adapted to constrain delivery through the second lumen to the target delivery location. Methods for treating tissues and organs via vascular pathways are provided.
