The invention further relates to methods of placing the compressed balloon into the lumen of a blood vessel or aneurysm, inflating and expanding the balloon, and then detaching the balloon from the delivery device while leaving the balloon in place in an expanded or inflated state. Further, the invention relates to a variety of delivery devices such as catheters for positioning, and inflating and expanding the balloon at a desired location. A catheter and a modified infusion wire are examples of such delivery devices. As such, the invention can be used to treat an aneurysm, for example, by leaving an expanded metal balloon in the aneurysm. Further, the surface of the metal balloon can be configured to promote tissue ingrowth and release drugs, pharmacologically active molecules, or pharmacologic compositions.
