    摘要: The present invention provides a removable vena cava filter for capturing thrombi in a blood vessel. The filter comprises a plurality of primary struts 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. 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 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: 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: 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.

    摘要: The present invention involves a removable filter for capturing thrombi in a blood vessel. The filter comprises a plurality of struts having first ends attached together along a longitudinal axis of the filter. Each strut has a body member extending from the first end along the longitudinal axis to an anchoring hook defining a strut axis. Each strut is configured to move along a strut path relative to the longitudinal axis between an expanded state for engaging with the blood vessel and a collapsed state for filter delivery or retrieval. Each anchoring hook has an angle of up to about 90 degrees relative to the strut axis.

    摘要: The present invention provides a method of capturing thrombi in a blood vessel, which includes delivering a removable filter in a collapsed state within the blood vessel and deploying the filter to an expanded state within the blood vessel. The filter includes a plurality of primary struts and a plurality of secondary struts emanating from a hub and extending arcuately along a longitudinal axis and linearly radially. Each primary strut has an arcuate segment including first and second curved portions. Each secondary strut includes first and second arcs. The primary struts terminate with an anchoring hook. Each primary strut crosses another primary strut along the longitudinal axis in the collapsed state such that the arcuate segments occupy a first diameter and the anchoring hooks occupy a second diameter, the first diameter being greater than the second diameter for filter retrieval or delivery. In the expanded state, the secondary struts centralize the filter in the blood vessel and the anchoring hooks engage with the blood vessel.
