MEDICAL DEVICE WITH CONNECTED LEGS

摘要

A vascular filter includes a hub and a basket portion. The filter is formed from a plurality of strands of a biocompatible material such as a polymer or a super-elastic metal alloy. The strands are intertwined to form the hub the strands are then secured by forming a knot such as a crown knot or a splice, and the free ends of the strands form a basket portion of the filter. The filter may thus be formed only by the strands, thereby avoiding problems associated with known methods of joining legs to form a filter.
