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 wherein the plurality of legs comprises a first set of legs coupled proximally to a hub and having a first length, and a second set of legs coupled proximally to the hub and having a s
1. A method of treating a patient, comprising: providing an implantable vessel filter including a plurality of legs wherein the plurality of legs comprises a first set of legs coupled proximally to a hub and having a first length, and a second set of legs coupled proximally to the hub and having a second length longer than the first length, each of the second set of legs having a hook at a distal end, anda center-post comprising grooved proximal and distal sections, at least some of the legs having a hook at a distal end, 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, wherein compressing the legs toward the center post includes placing the first set of legs in a corresponding groove in the grooved proximal section;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; anddeploying the filter at the desired location, the filter transitioning from the filter compressed configuration to the filter expanded configuration. 2. The method according to claim 1, wherein the deploying comprises an end of each of the first set of legs remote from the hub engaging a wall of a vessel at the desired location at a first circumferential position and each hook penetrating the wall of the vessel at a second circumferential position different from the first circumferential position. 3. The method according to claim 1, wherein the deploying comprises each hook penetrating a wall of a vessel at the desired location. 4. The method according to claim 1, wherein at least the plurality of legs are formed from a shape memory material, the method further comprising temperature-setting the plurality of legs in the filter compressed configuration. 5. The method according to claim 1, wherein the deploying comprises each hook penetrating a wall of a vessel at the desired location, further comprising after the deploying: re-compressing the plurality of legs toward the center-post; and removing the filter from the body of the patient. 6. The method according to claim 1, wherein the filter comprises a retrieval interlocking mechanism, further comprising after the deploying: engaging the retrieval interlocking mechanism; and removing the filter from the body of the patient. 7. The method according to claim 1, wherein the plurality of legs comprises six legs, each of the six legs having a hook at a distal end thereof, wherein the grooved distal section includes six flanges configured to separate the hooks on the distal end of the legs in the filter compressed configuration, the flanges spaced approximately equidistant from each other, and wherein the compressing comprises positioning each hook between adjacent flanges. 8. A method of treating a patient, comprising: providing an implantable vessel filter including a plurality of legs, at least some of the legs having a hook a distal end;an extension distal of the grooved distal section, anda center-post having a grooved distal section,wherein 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;holding the filter via the extension during the compressing;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; anddeploying the filter at the desired location, the filter transitioning from the filter compressed configuration to the filter expanded configuration.
