    • A collapsible filter element for a transcatheter embolic protection device, the filter element comprises a collapsible filter body of polymeric material which is movable between a collapsed stored position for movement through a vascular system and an expanded position for extension across a blood vessel such that blood passing through the blood vessel is delivered through the filer element. A proximal inlet portion of the filter body has one or more inlet openings sized to allow blood and embolic material enter the filter body. A distal outlet portion of the filter body has a plurality of generally circular outlet openings sized to allow through-passage of blood, but to retain embolic material within the filter body. The distal outlet portion of the filter body in the region of the outlet openings has means for reducing shear stress on blood passing through the outlet openings. The shear stress reducing means includes lead-in and lead-out radiussed portions of the filter body leading to the outlet holes. The porosity of the distal portion of the filter body decreases towards the distal end. A blind portion extends for at least 5% of the length of the body. Preferably there are between 200 and 300 outlet opening with an average diameter of approximately 150 microns.

    • Multilayer packaging materials and multilayer containers including a barrier material having excellent resistance to gas permeability are provided. The multilayer packaging materials and containers include at least one permeable polymeric material and at least one layer of a barrier material which is a reaction product of: (i) an ungelled amine-functional polymeric resin, which is a reaction product of a polyamine and a polyfunctional material having at least two functional groups reactive with said polyamine, the ungelled polymeric resin further containing an average of greater than two polyamine moieties per molecule within said resin; and (ii) a material selected from the group consisting of a polyepoxide, polyoxalate or mixtures thereof, the barrier material characterized as containing at least about four percent by weight amine nitrogen and having an oxygen permeability of less than about 3 cc-mil/100 in -day-atmosphere and a carbon dioxide permeability of less than about 15 cc-mil/100 in -day-atmosphere at 23 DEG C and zero percent relative humidity. The barrier material can be formed from coating compositions including as co-curable resinous materials, e.g., a polyepoxide and an ungelled amine-functional polymeric resin formed from polymeric resin which is a reaction product of a polyamine having up a polyepoxide and a polyamine having up to about two primary amino nitrogen groups per molecule, the polyamine and polyepoxide present in a reaction mixture at a molar ratio of from about 1.4:1 to about 0.83:1 .
