Abstract
A compact blood clot filter having an alignment section that overlaps with a filter section in an axial direction is formed from a single tube without any welding points to provide high structural integrity, low profile and low manufacturing cost. The filter section has filter struts that extend radially and longitudinally from a hub. The alignment section has alignment struts in which the downstream end of each alignment strut forms a junction with the downstream end of an adjacent alignment strut while the upstream end of each alignment strut forms a junction with the upstream end of an adjacent alignment strut and with one of the filter struts to ensure symmetrical deployment of the filter struts and provide stable centering of the filter section.
