Embolic protection system
First Claim
1. An embolic protection system comprising:
- a guidewire for advancing through a vasculature, the guidewire having a distal end and a proximal end;
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 having a guidewire path for slidably receiving the guidewire to permit movement of the filter relative to the guidewire when the filter is in the collapsed configuration and the expanded deployed configuration;
a delivery catheter advanceable over the guidewire for deliver of the embolic protection filter;
the delivery catheter having a proximal end and a distal end, the filter being deployed from the distal end of the delivery catheter into the expanded deployed configuration;
a retrieval catheter advancable over the guidewire for retrieval of the filter, the retrieval catheter having a distal end and proximal end; and
engagement elements for engaging the embolic protection filter with the guidewire for retrieval of the filter into the retrieval catheter in the collapsed configuration.

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. A retrieval catheter 3 is also advancable 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.
