    摘要： The present invention involves a removable filter for capturing thrombi in a blood vessel. The filter comprises a plurality of primary struts and a plurality of secondary struts. The plurality of primary struts has first ends attached together along a longitudinal axis. Each primary strut has an arcuate segment extending from the first end to an anchoring hook. The primary struts are configured to move between an expanded state for engaging the anchoring hooks with the blood vessel and a collapsed state for filter retrieval or delivery. Each primary strut is configured to cross another primary strut along the longitudinal axis in the collapsed state such that each anchoring hook faces the longitudinal axis away from the blood vessel for filter retrieval or delivery. The plurality of secondary struts has connected ends attached together along the longitudinal axis. The secondary struts extend therefrom to free ends to centralize the filter in the expanded in the blood vessel.

    摘要： The present invention provides a removable vena cava filter (10) for capturing thrombi in a blood vessel. The filter comprises a plurality of primary struts (12) having first ends attached together along a longitudinal axis. Each primary strut includes an arcuate segment having a first tensile strength. The arcuate segment extends from the first end to an anchoring hook (26). The anchoring hook is integral with the arcuate segment and having the first thickness and first tensile strength. The filter further comprises a plurality of secondary struts (30) freely spaced between the primary struts and having connected ends attached together along the longitudinal axis. Each secondary strut freely extends from the connected end to a free end avoiding contact with other secondary struts and primary struts. Each secondary strut has a second tensile strength.

    摘要： A removable filter (10) having a collapsed state and an expanded state for capturing thrombi in a blood vessel is disclosed. The filter comprises a plurality of primary struts (12) and a plurality of secondary struts. Each primary strut in the expanded state extends from a primary strut first end to an anchoring hook (26). Each primary strut extends arcuately along a longitudinal axis and linearly radially. The plurality of primary strut first ends are attached together along the longitudinal axis (x). Each secondary strut in the expanded state extends from a secondary strut first end to a free end. Each secondary strut extends arcuately along the longitudinal axis and linearly radially. The plurality of secondary struts are attached together along the longitudinal axis. The plurality of secondary struts centralize the filter in the expanded state in the blood vessel.

    摘要： A removable vena cava filter configured for simplified delivery to and retrieval from the vena cava of a patient is disclosed. In one embodiment, the filter comprises a plurality of primary struts (12) having first ends attached together along a longitudinal axis. The primary struts are movable between a closed state during delivery to the blood vessel and an open state when engaged with the blood vessel. Each primary strut comprises a first portion (20), a second portion (23), and a axial bend (25). The first portion extends from the first end and generally is disposed within a first portion plane intersecting the longitudinal axis. The axial bend is oriented along a circumferential direction relative to the longitudinal axis. The second portion generally is disposed within a second portion plane intersecting the first portion plane and terminates at an anchoring hook (A).
