Abstract
A method for occluding aneurysms or peripheral blood vessels is provided which allows for isovolumetric, isobaric delivery of occluding agents to aneurysms or peripheral blood vessels, wherein the aneurysms or peripheral blood vessels are isolated from the general circulation until the occluding agent has stabilized or until occlusion is effected. In particular, a double balloon method for occluding aneurysms or peripheral blood vessels is disclosed wherein a first balloon is inserted into the aneurysm or peripheral blood vessel to deliver an occluding agent, and a second balloon is placed such that it substantially covers the neck of the aneurysm or peripheral blood vessel to substantially seal the aneurysm or peripheral blood vessel from the general circulation. Additionally, an aneurysm or peripheral blood vessel comprising a double balloon configuration useful for occluding aneurysms or peripheral blood vessels is disclosed.
