1. A method of treating an aneurysm in a patient, comprising the step of:
- delivering, within an aqueous space defined by an inner wall of the aneurysm and an outer wall of a medical device within the aneurysm, an in situ forming foam that comprises a polymer and reacts in the space to generate a gas and form a foam structure, which has a plurality of cells that contain said gas within a skin, and which is in conformal contact with tissue surrounding the space.

Abstract
Systems, methods and kits relating to in-situ forming polymer foams for the treatment of aneurysms or fluid filled spaces are disclosed. The systems include an insertable medical device and an in-situ forming foam of lava like materials with a fast forming outer skin and a slower hardening interior that is formed from a one-, two- or multi-part formulation. When used to treat an aneurysm, the foam is placed into contact with at least a portion of an exterior surface of the medical device and/or the tissue surface of the aneurysm.
