  • Patent number: 8123778
    Abstract: An embolic protection system comprises an embolic protection filter 1 having a collapsed delivery configuration and an expanded deployed configuration. The filter 1 is housed in the collapsed configuration in a reception space of a delivery catheter 20. The delivery catheter 20 containing the filter 1 is housed in a sealed sterile pouch 35. The filter 1 may be coated with a non-thrombogenic coating and an adhesion preventer 9 such as a silicon gel is used to substantially prevent adhesion of adjacent folds of the filter 1 when the filter is in the collapsed configuration in the delivery catheter 20.

  • Patent number: 8123776
    Abstract: 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.

  • Patent number: 8114115
    Abstract: 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.

  • Patent number: 8057504
    Abstract: An embolic protection device has a collapsible filter element (105) mounted on a carrier such as a guidewire (101). The filter element (105) collapses into the outer end of a catheter (118) for deployment and retrieval through a vascular system of a patient. The filter element (105) has a collapsible filter body with a proximal inlet end and a distal outlet end. The proximal inlet end has inlet openings sized to allow blood and embolic material enter the filter body. The outlet end has outlet openings which allow through passage of blood but retain embolic material within the filter body. After use, the catheter (118) is movable along the guidewire (101) to engage the proximal end of the filter element and close the inlet openings before sliding over the filter element from the proximal end to the distal end to progressively collapse the filter body on the guidewire (101) for retrieval.

  • Patent number: 8038697
    Abstract: A collapsible filter element for a transcatheter embolic protection device, the filter element comprises a collapsible filter body of polymeric material 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 filer 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. A distal outlet portion of the filter body has a plurality of generally circular outlet openings sized to allow through-passage of blood, but to retain embolic material within the filter body. The distal outlet portion of the filter body in the region of the outlet openings has means for reducing shear stress on blood passing through the outlet openings. The shear stress reducing means includes lead-in and lead-out radiussed portions of the filter body leading to the outlet holes.

  • Publication number: 20110125182
    Abstract: A medical guidewire assembly comprises a guidewire having a flexible tip. A medical device such as a collapsible filter for use as an embolic protection device is mounted on the guidewire. The filter is advanced through a body lumen with the guidewire tip extending distally. A variable thickness guidewire (having a recess or thinner segment between thicker segments) can be employed. At a first location the filter is advanced relative to the tip to a location which is distally advanced from the first location. Placement of the filter in an optimal distal location is thereby achieved.
