Abstract: A flowable, biodegradable endovascular embolic composition effective for embolizing a vascular defect consisting essentially of: (a) a biocompatible, biodegradable polymer or polymeric material forming composition; (b) a biocompatible embolic solvent for the polymer or polymer forming composition capable of diffusion into mammalian tissue; (c) biocompatible magnetic particles responsive to a magnetic field; wherein: the polymer or polymeric forming material and solvent are present in the composition in amounts and relative proportions such that (1) the composition is deliverable to a vascular defect site and (2) upon delivery to the site, solidifies into an embolic mass; and the magnetic particles are present in the composition in an amount sufficient to enable the composition being deliverable to the vascular site by a magnetic field. Also disclosed are methods and articles of manufacture embodying the above-described composition.

Abstract: A coaxial double lumen tube adapted for forming an endovascular graft which comprises an outer tube positioned over an inner tube, both tubes being made of a material acceptable for use in endovascular grafts and having an internal and external diameter and a wall thickness, the outer tube having an internal diameter and the inner tube having an external diameter such that a space is created between the outer tube and inner tube, said space being at least partially filled with an uncured adhesive which, upon curing after endovascular implantation, cures to adhere said inner and outer tubes together to form a self-supportive tube.
