  • Publication number: 20200030076
    Abstract: A vascular filter device (1) comprises a plurality of filter elements (6) which are movable from a capturing position to an open position upon elapse of a predetermined period of time. In the capturing position the filter elements (6) are configured to capture thrombus passing through the inferior vena cava. In the open position the filter elements (6) are configured to facilitate unrestricted blood flow. The filter elements (6) are biased towards the open position. The filter (1) comprises a holder member (10) to temporarily hold the filter elements (6) in the capturing position until elapse of the predetermined period of time. The holder member (10) comprises a biostable wire element (12) which extends through an opening (13) in each filter element (6), and a biodegradable/bioabsorbable stop element (11). Upon biodegrading/bioabsorbing of the stop element (11), the filter elements (6) are free to move from the capturing position to the open position.

  • Publication number: 20180280129
    Abstract: A vascular filter device comprises a support; and a filter comprising one or more filter elements configured to capture thrombus passing through a blood vessel. A holder holds the filter in a closed filtering state and releases to convert the filter to an open state after a period of time. The filter is adapted to retain thrombus after said conversion. In one case the filter elements are arranged to remain in a closed state after released by the holder, because they are blocked by a retained clot from opening fully, and the filter elements are biased to the open state with a bias level which is counter balanced by force exerted by a retained clot under action of blood flow.

  • Publication number: 20180256308
    Abstract: A vascular filter device (1) has a support frame (2) and filter elements (4). The filter elements (4) extend from the support frame towards filter element ends forming an on-axis apex (5) at which they are interconnected by a holder (6). The filter elements (4) are biased such that if unconnected the filter element ends are located between the support frame and said central axis when the vascular filter device is unconstrained. The filter element unconnected positions are provided by the filter element shapes and the angles at which they extend from the support frame, and in one example this is achieved by laser cutting tubing and heat setting the material.

  • Publication number: 20180193128
    Abstract: A vascular filter (1) comprises a proximal support hoop (3), a plurality of support struts (5), and a plurality of capture arms (6). The proximal support hoop (3) extends around the internal wall of the inferior vena cava in a wave pattern having six distal peaks (11) and six proximal peaks (11). The proximal support hoop (3) comprises an enlarged end element at each peak (11). The support struts (5) extend longitudinally along the internal wall of the inferior vena cava in a curve (14). Two capture arms (6) are connected to the proximal support hoop (3) at each distal peak (11). Each capture arm 6 extends from the distal peak (11) to an apex (7) in a curve (12, 13). The concave portion of the first curve (12) faces inwardly towards the concave portion of the second curve (13).

  • Publication number: 20170340429
    Abstract: A vascular filter system comprises a vascular filter (1), a clamp device (50), and a delivery catheter (51). The filter (1) comprises filter elements (6). When used without the clamp device (50), the filter elements (6) move from a closed state to an open state upon elapse of a predetermined period of time. In the closed state the filter elements (6) capture thrombus passing through the inferior vena cava (2). The delivery catheter (51) is employed to deliver the clamp device (50) to the filter (1) after the filter (1) has been deployed in the inferior vena cava (2). The clamp device (50) engages with the filter elements (6) of the filter (1) to clamp the filter (1) in the closed state beyond elapse of the predetermined period of time. Because of the presence of the clamp device (50), the filter elements (6) are no longer free to move from the closed state to the open state upon elapse of the predetermined period of time.
