    摘要: Intravascular filters formed by a molding process can have a plurality of integrally formed apertures. A molding process can utilize a mold assembly that includes a mold having a mold surface and a die having a die surface. The mold assembly includes plurality of protrusions that extend from at least one of the mold surface and the die surface. A molten material is placed within a portion of the mold, and the die is then inserted into the mold such that the plurality of protrusions span a distance between the die surface and the mold surface. The molten material is allowed to solidify, thereby forming a filter membrane that includes a plurality of integrally formed apertures.

    摘要: Intravascular filters can include a filter membrane having a hydrophilic polymer coating on the filter membrane. The hydrophilic polymer coating can be on an inner surface, an outer surface or both an inner surface and an outer surface of the filter membrane. Intravascular filters including a hydrophilic polymer coating may be considered as providing increased hemocompatibility, decreased risk of filter-induced thrombosis and reduced sheathing forces.
