Publication number: 20180280129Abstract: 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.Type: ApplicationFiled: October 27, 2017Publication date: October 4, 2018Applicant: Novate Medical LimitedInventors: Steven HORAN, Paul GILSON, Karl KEATING, Jerome HENRY, Jacqueline O'GORMAN, Ronan O'CONNOR, Shane MOLLOY

Publication number: 20180256308Abstract: 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.Type: ApplicationFiled: October 18, 2017Publication date: September 13, 2018Applicant: Novate Medical LimitedInventors: Paul GILSON, Steven HORAN, Karl KEATING, Damien RYAN, Jacqueline O'GORMAN, Paul BATEMAN, Martin KEEGAN, Declan BRODERICK

Publication number: 20180028304Abstract: 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.Type: ApplicationFiled: February 9, 2017Publication date: February 1, 2018Applicant: Novate Medical LimitedInventors: Steven HORAN, Paul GILSON, Karl KEATING, Aidan GOGGIN, Jerome HENRY, Jacqueline O'GORMAN, Shane MALLOY

Publication number: 20170340429Abstract: 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.Type: ApplicationFiled: December 14, 2016Publication date: November 30, 2017Applicant: Novate Medical LimitedInventors: Paul GILSON, Steven HORAN, Karl KEATING, Aidan GOGGIN

Publication number: 20160038270Abstract: A vascular filter device (1) has a support (2) for engaging the wall of a blood vessel. A filter has filter elements (5) having proximal segments (10) connected to the support (3) and distal segments at least temporarily restrained at a distal apex (7) by a holder when in a filtering closed position. At least one filter element (5) extends radially outwardly with respect to a device longitudinal axis when unconstrained. The filter element may extend in a curve with a concave portion facing radially outwardly in an unconstrained configuration.Type: ApplicationFiled: March 12, 2014Publication date: February 11, 2016Applicant: Novate Medical LimitedInventors: Steven HORAN, Paul GILSON, Karl KEATING, Dara FINNERAN, Jacqueline O'GORMAN, Damien RYAN, Megan MACDONAGH, Paul BATEMAN

Publication number: 20100191272Abstract: A distal access embolic protection system and methods of using the same for the capture and removal of embolic material from a blood vessel during an interventional procedure are provided. A distal access embolic protection system is inserted through the wall of the blood vessel at a position distal to a stenosis and a distal access filter device is deployed at the point of insertion. After the filter is deployed and is filtering blood that is flowing across the treatment site, an interventional procedure can be performed at the treatment site. After the procedure, the filter device can be collapsed and removed from the blood vessel. A further method is provided wherein a second embolic protection system including a second filter is advanced to the treatment site using a transcatheter technique after the distal access filter has been deployed. A distal access embolic protection system is also provided.Type: ApplicationFiled: January 23, 2009Publication date: July 29, 2010Applicant: SALVIAC LIMITEDInventor: Karl KEATING
