<p>A non-coextrusion process for making multi-layer angioplasty balloons involves pre-forming separate parisons (10, 12) and then concentrically disposing the plural parisons to form a composite parison which is then subjected to a blow-molding process. The resulting balloon can have its properties tailored by appropriate selection of the particular plastics to be used for the multiple parisons.</p> |
