摘要

A method of treating a patient includes providing an implantable vessel filter including a plurality of legs and center-post, inserting the filter into a delivery assembly, and deploying the filter at a desired location in a patient's body. One or more of the legs may have a hook at a distal end thereof and the center-post includes a grooved distal section to receive the hooks. The filter legs transition from a compressed configuration to an expanded configuration during deployment.
