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).

Abstract: A data sensor may be configured in accordance with some embodiments to have a magnetically responsive stack that contacts at least one shield. The at least one shield may be constructed with a non-rectangular shaped electrical contact, such as a triangular and trapezoidal shape, respectively positioned on top and bottom shields on opposite sides of the magnetically responsive stack.

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.

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.
