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 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.

Claims

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 distal end, a proximal end, a retracted configuration and an expanded deployed configuration, the filter being movable along the guidewire; and

a delivery catheter advanceable over the guidewire for delivery of the embolic protection filter, the delivery catheter having a proximal end and a distal end,

the delivery catheter having a slot in a sidewall thereof defining a guidewire exit so that the guidewire is located in a lumen of the delivery catheter in only a distal portion thereof.

2. The system of claim 1 further comprising a deploying member for moving a retracted filter relative to the distal end of the delivery catheter.

3. The system of claim 2 wherein the deploying member comprises a tube.

4. The system of claim 3 wherein the tube has a side entry hole through which the guidewire extends.

5. 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 distal end, a proximal end, a retracted configuration and an expanded deployed configuration, the filter being movable along the guidewire; and

a retrieval catheter advanceable over the guidewire for retrieval of the filter,

the retrieval catheter having a slot in the sidewall thereof definining a guidewire exit so that the guidewire is located in a lumen of the retrieval catheter in only a distal portion thereof.
