AN EMBOLIC PROTECTION SYSTEM

摘要

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 dista l 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) whe n 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 guidewi re (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.
