摘要：
A removable vena cava filter configured for simplified delivery to and retrieval from the vena cava of a patient is disclosed. The filter includes struts configured to be arranged in consistent orientation together between expanded (opened) and collapsed (closed) configurations, thereby minimizing entanglement of the struts. Each of the struts has a circumferential bend relative to the longitudinal axis of the filter. The circumferential bends allow for consistent orientation of the struts when moved between the expanded and collapsed configurations and when placed in the closed configuration of the filter.
