Abstract
Systems, methods and kits relating to in-situ forming polymer foams for the treatment of aneurysms are disclosed. The systems include an insertable medical device and an in-situ forming foam that is formed from a polymer that reacts in an aqueous environment. 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.
Claims20
A method for treating an aneurysm within a patient, the aneurysm characterized by a first end, a second end, and a surface between the first and second ends, said method comprising the steps of:
- placing a medical device within said aneurysm, said medical device comprising a structure having a first end, a second end, and an exterior surface between said first and second ends;
- delivering, with a catheter, a material between the exterior surface of said medical device and the surface of the aneurysm;
- and
- forming a foam from said material upon delivery between the exterior surface of said medical device and the surface of the aneurysm;
- wherein (a) said foam is formed by the reaction of said material with blood in situ and (b) the reaction includes the generation of a gas, said gas expanding a portion of the material into an interstitial area.
