Patent number: 7972352Abstract: An embolic protection system having a guidewire for advancing through a vasculature; an embolic protection filter having a filter body with a distal end and a proximal end, the filter body providing for a collapsed configuration and an expanded deployed configuration. The embolic protection filter body has a guidewire path for slidably receiving the guidewire to permit movement of the filter relative to the guidewire when the filter 1 is in the collapsed configuration and the expanded deployed configuration. A delivery catheter is advanceable over the guidewire for delivery of the embolic protection filter. A retrieval catheter is also advanceable over the guidewire for retrieval of the filter , and engagement elements are used for engaging the embolic protection filter with the guidewire for retrieval of the filter into the retrieval catheter in the collapsed configuration.Type: GrantFiled: November 4, 2004Date of Patent: July 5, 2011Assignee: Salviac LimitedInventors: Paul Gilson, Charles Taylor, Patrick Grirrin, John Nielan, David Vale, Eamon Brady

Patent number: 7967837Abstract: A delivery catheter 1 has a distal pod 2 for reception of an embolic protection filter 3. The filter 2 is moved from a retracted delivery configuration to an extended deployed configuration by a push wire 6 which has an engagement hoop 7 at the distal end. Retraction of a handle 9 has the effect of retracting the pod 3 relative to the push wire 6 and the engagement hoop 7 and the filter 2 is effectively deployed by pushing it out of the pod 3.Type: GrantFiled: June 27, 2002Date of Patent: June 28, 2011Assignee: Salviac LimitedInventor: David Vale

Patent number: 7927349Abstract: A support 103 for an embolic protection device comprises round wires 116 which may form one or more support hoops for a filter body. The circumferential hoop formed by the wires 116 ensures that in the expanded position, the filter body 102 will be supported by the support frame 103 in circumferential apposition with the interior wall of the vasculature. The wires 116 may have a strain distributing linkage element in the form of a loop 120. The loop 120 acts as a diameter or circumference adjuster allowing an embolic protection device to adapt to different Bessel contours and sizes whilst maintaining apposition with the vessel wall. The strain relieving geometry of the loops enhances the compliance of the bend points without creating a weakened hinge point, thus ensuring that there is no discontinuity in the circumferential seal against the vessel wall.Type: GrantFiled: June 13, 2007Date of Patent: April 19, 2011Assignee: Salviac LimitedInventors: Eamon Brady, David Vale, Ronald Kelly, John Neilan, Steven Horan, Gerard Rabbitte, Gerry McCaffrey
