Publication number: 20090149881Abstract: A collapsible filter element for a transcatheter embolic protection device comprises a collapsible filter body which is movable between a collapsed stored position for movement through a vascular system and an expanded position for extension across a blood vessel such that blood passing through the blood vessel is delivered through the filter element. A proximal inlet portion of the filter body has one or more inlet openings sized to allow blood and embolic material enter the filter body and a distal outlet portion of the filter body has a plurality of outlet openings sized to allow through-passage of blood, but to retain embolic material within the filter body. The filter body is at least partially of laminate construction comprising a membrane coated with a coating which is biocompatible, the thickness of the coating being from 4% to 40% of the thickness of the membrane. The coating may be of hydrophilic material.Type: ApplicationFiled: January 6, 2009Publication date: June 11, 2009Applicant: SALVIAC LIMITEDInventors: David Vale, Eamon Brady

Publication number: 20080058766Abstract: A medical catheter for the transvascular deployment of a collapsible medical device such as a filter has a tubular body formed by an inner tubular core surrounded by an outer thin-walled tube which is fixed to the core. The outer thin-walled tube extends outwardly beyond a distal end of the core to form a fixed thin-walled medical device embracing pod. The filter is carried on a guidewire which is slidably engagable within a central lumen of the core and the filter can be collapsed against the guidewire for loading within the pod. With the filter thus loaded within the pod the distal end of the catheter can be maneuvered through a patient's vascular system to a desired deployment site where the filter is discharged from the pod allowing the filter to expand within the blood vessel for use filtering blood flowing through the blood vessel.Type: ApplicationFiled: November 13, 2006Publication date: March 6, 2008Inventors: Paul Gilson, David Vale, Eamon Brady

Publication number: 20080033481Abstract: An embolic protection system 1 comprises a guidewire 99 for advancing through a vasculature, the guidewire 99 having a distal end and a proximal end; an embolic protection filter 1 having a filter body 41 with a distal end and a proximal end, the filter body 41 providing for a collapsed configuration and an expanded deployed configuration. The embolic protection filter body 41 has a guidewire path for slidably receiving the guidewire 99 to permit movement of the filter 1 relative to the guidewire 99 when the filter 1 is in the collapsed configuration and the expanded deployed configuration. A delivery catheter 2 is advanceable over the guidewire 99 for delivery of the embolic protection filter 1; the delivery catheter 2 having a proximal end and a distal end. The filter 1 is deployed from the distal end of the delivery catheter 2 into the expanded deployed configuration.Type: ApplicationFiled: August 20, 2007Publication date: February 7, 2008Applicant: SALVIAC LIMITEDInventors: Paul Gilson, Charles Taylor, Patrick Griffin, John Nielan, David Vale, Eamon Brady

Publication number: 20070282370Abstract: A retrieval catheter 1 comprises a distal tubular sheath 2 with a reception space 5 into which an embolic protection filter 10 may be retrieved. An elongate connector 10 extends proximally from the sheath 2 to allow a clinician to control movement of the sheath 12. The sheath 2 is backloaded over a procedural catheter such as a balloon catheter 20, for example for post dilatation of a stent 55. The procedure is more efficient and procedure time is reduced because a catheter system is provided which allows a procedural step to be carried out and a filter 50 to be retrieved.Type: ApplicationFiled: August 14, 2007Publication date: December 6, 2007Applicant: SALVIAC LIMITEDInventors: Eamon Brady, Charles Taylor, Patrick Griffin, Brendan Casey, David Vale
