<p>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. A retrieval catheter (3) is also advanceable over the guidewire (99) for retrieval of the filter (1), the retrieval catheter (3) having a distal end and a proximal end; and engagement elements for engaging the embolic protection filter (1) with the guidewire (99) for retrieval of the filter (1) into the retrieval catheter (3) in the collapsed configuration.</p> |
