Abstract
A compact retrievable blood clot filter has a filter section, a releasable lock and an alignment section connected to the filter section. Alignment ribs of the alignment section have releasable upstream ends that are locked to the filter by the releasable lock. The releasable upstream ends of the alignment ribs are capable of being released from the releasable lock so that during retrieval of the filter, the alignment ribs can slide through the endothelial tissue that may have grown around the alignment ribs.
