Non-entangling vena cava filter

摘要

A method of treating a patient includes providing an implantable vessel filter including a plurality of legs and a 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.

1. A method of treating a patient, comprising:
providing an implantable vessel filter including a plurality of legs and a center-post, at least some of the legs having a hook at a distal end thereof, the center-post having a grooved distal section, the plurality of legs extending radially outward from the center-post in a filter expanded configuration; compressing the legs toward the center-post and positioning each of the hooks in a corresponding groove in the grooved distal section in a filter compressed configuration; inserting the filter in the filter compressed configuration into a delivery assembly and navigating the filter to a desired location in a body of the patient; and deploying the filter at the desired location, the filter transitioning from the filter compressed configuration to the filter expanded configuration.
