Abstract

A device, method, and system of deploying an embolic protection device at a location distal to a treatment site in a vessel of a patient. A delivery catheter is encircled by a sealing member which is expandable from a delivery configuration to a deployed configuration. The device creates a seal to prevent the flow of blood during the treatment of vascular disease. A distal protection element is delivered by the delivery catheter and deployed to filter or remove embolic debris.

Claims

1. A delivery catheter for use in occluding the flow of blood in a lumen of a vessel of a human vascular system comprising:

an elongate tubular member having a distal end, and a wall defining a lumen extending from the distal end to a location proximal of the distal end; and

a sealing member having proximal and distal ends, and being positioned about the elongate tubular member such that the sealing member is positionable in direct contact with an outer surface of the elongate tubular member, the sealing member being expandable from a delivery configuration to a deployed configuration, the sealing member being sized to fill the lumen of the vessel in the deployed configuration, the sealing member being positioned about the elongate tubular member such that the elongate tubular member is slidable in relation to the proximal and distal ends of the sealing member while the sealing member is in the deployed configuration and contacting the lumen of the vessel, the distal end of the elongate tubular member being a distal end of the delivery catheter, the sealing member including a plurality of reinforcing elements configured and dimensioned to frictionally engage the elongate tubular member when the sealing member is in the delivery configuration to maintain the position of the sealing member in relation to the elongate tubular member, and disengage the elongate tubular member when the sealing member is in the deployed configuration.

2. The delivery catheter of claim 1, wherein in the deployed configuration the sealing member is cone shaped having an apex pointed towards the distal end of the delivery catheter.

3. The delivery catheter of claim 1, wherein in the deployed configuration the sealing member is bulb shaped.

4. The delivery catheter of claim 1, wherein the sealing member is self-expandable.

5. A system for occluding blood flow in a lumen of a vessel of a human vascular system comprising:

a guide catheter having proximal and distal ends, and a wall defining a lumen extending through the guide catheter; and

a delivery catheter comprising;

an elongate tubular member having a distal end, and a wall defining a lumen extending from the distal end to a location proximal of the distal end; and

a sealing member having proximal and distal ends, and being positioned about the elongate tubular member such that the sealing member is positionable in direct contact with an outer surface of the elongate tubular member, the sealing member being expandable from a delivery configuration to a deployed configuration, the sealing member being sized to fill the lumen of the vessel in the deployed configuration, the sealing member being positioned about the elongate tubular member such that the elongate tubular member is slidable in relation to the proximal and distal ends of the sealing member while the sealing member is in the deployed configuration and contacting the lumen of the vessel, the distal end of the elongate tubular member being the distal end of the delivery catheter, the sealing member including a plurality of reinforcing elements configured and dimensioned to frictionally engage the elongate tubular member when the sealing member is in the delivery configuration to maintain the position of the sealing member in relation to the elongate tubular member, and disengage the elongate tubular member when the sealing member is in the deployed configuration.

6. The system of claim 5, wherein in the deployed configuration the sealing member is cone shaped having an apex pointed towards the distal end of the delivery catheter.

7. The system of claim 5, wherein in the deployed configuration the sealing member is bulb shaped.

8. The system of claim 5, wherein the sealing member is self-expandable.

9. A system for protecting a patient from emboli released during an intravascular procedure performed at a treatment site in a vessel of a patient comprising:

a guide catheter having proximal and distal ends, and a wall defining a lumen extending through the guide catheter;

a delivery catheter comprising;

an elongate tubular member having a distal end, and a wall defining a lumen extending from the distal end to a location proximal of the distal end; and

a sealing member having proximal and distal ends, and being positioned about the elongate tubular member such that the sealing member is positionable in direct contact with an outer surface of the elongate tubular member, the sealing member being expandable from a delivery configuration to a deployed configuration, the sealing member being sized to fill the lumen of the vessel in the deployed configuration, the sealing member being positioned about the elongate tubular member such that the elongate tubular member is slidable in relation to the proximal and distal ends of the sealing member while the sealing member is in the deployed configuration and contacting the lumen of the vessel, the distal end of the elongate tubular member being the distal end of the delivery catheter, the sealing member including a plurality of reinforcing elements configured and dimensioned to frictionally engage the elongate tubular member when the sealing member is in the delivery configuration to maintain the position of the sealing member in relation to the elongate tubular member, and disengage the elongate tubular member when the sealing member is in the deployed configuration; and

an embolic protection device sized to be delivered through the lumens of the guide catheter and the delivery catheter to a location in the vessel distal to the treatment site.

10. The system of claim 9, wherein in the deployed configuration the sealing member is cone shaped having an apex pointed towards the distal end of the delivery catheter.

11. The system of claim 9, wherein in the deployed configuration the sealing member is bulb shaped.

12. The system of claim 9, wherein the sealing member is self-expandable.

13. The system of claim 9, wherein the embolic protection device is a filtration device.

14. The system of claim 9, wherein the embolic protection device is an occlusive device.
