  • Embolic protection system
    Patent number: 7972352
    Abstract: 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.

  • Embolic protection system
    Publication number: 20060074446
    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.
