Abstract

Embodiments of the invention relate generally to systems and methods for providing embolic protection to a medical procedure by filtration of debris generated by the medical procedure. The system and methods include an embolic protection device having an ultrasound transducer for assisting in intravascular navigation of the device.

Claims (78)

1. A system for providing embolic protection, the system comprising:

an embolic protection device comprising:

a guidewire having a proximal end, a distal end, and a first pressure sensor located near the distal end of the guidewire;

a first sheath having a proximal end, a distal end and a lumen, the lumen configured to receive the guidewire;

a first distal protection filter attached to a distal portion of the first sheath;

a second sheath having a proximal end, a distal end and a lumen, the second sheath disposed over the first sheath, wherein the distal end of the second sheath is located proximally the first distal protection filter;

a second distal protection filter attached to a distal portion of the second sheath;

an outer sheath disposed over both the first sheath and the second sheath; and

an intravascular ultrasound transducer disposed at the distal end of one of the first sheath, second sheath, or outer sheath;

a user interface configured to receive input from an operator regarding a surgical procedure including an insertion site and a destination site;

a display;

a processor programmed to:

receive input from the user interface regarding the surgical procedure;

determine anatomical landmarks between the insertion site and the destination site;

receive an intravascular ultrasound signal from the intravascular ultrasound transducer;

process the intravascular ultrasound signal into an image; and

send the image to the display.

2. The system of claim 1 , wherein the processor is further programmed to:

identify any anatomical landmarks in the image; and

tag the anatomical landmarks in the displayed image.

3. The system of claim 2 , wherein the processor is further programmed to:

determine a location of the embolic protection device based on the identified anatomical landmarks in the image.

4. The system of claim 3 , wherein the processor is further programmed to:

determine whether the location is the destination site.

5. The system of claim 4 , wherein the processor is further programmed to:

send a visual indicator to the display when the location has been determined to be the destination site.

6. The system of claim 5 , wherein the visual indicator is color coded.

7. The system of claim 1 , wherein the processor is further programmed to:

determine an orientation of the embolic protection device with respect to anatomical landmarks using the processed intravascular ultrasound imaging signal.

8. The system of claim 1 , wherein the processor is further programmed to:

generate instructions for adjusting the position of the embolic protection device based on the determined orientation of the embolic protection device.

9. A system for providing embolic protection, the system comprising:

an embolic protection device comprising:

a first elongate member having a proximal end and a distal end;

a first distal protection filter attached to a distal portion of the first elongate member;

a first sheath having a proximal end, a distal end and a lumen, the first sheath disposed over the first elongate member, wherein the distal end of the first sheath is located proximally the first distal protection filter;

a second distal protection filter attached to a distal portion of the first sheath; and

an outer sheath disposed over both the first elongate member and the first sheath, the distal portion of the outer sheath comprising a rapid exchange guidewire lumen.

an intravascular ultrasound transducer disposed at the distal end of one of the first sheath or outer sheath;

a user interface configured to receive input from an operator regarding a surgical procedure including an insertion site and a destination site;

a display;

a processor programmed to:

receive input from the user interface regarding the surgical procedure;

determine anatomical landmarks between the insertion site and the destination site;

receive an intravascular ultrasound signal from the intravascular ultrasound transducer;

process the intravascular ultrasound signal into an image; and

send the image to the display.

10. The system of claim 9 , wherein the processor is further programmed to:

identify any anatomical landmarks in the image; and

tag the anatomical landmarks in the displayed image.

11. The system of claim 10 , wherein the processor is further programmed to:

determine a location of the embolic protection device based on the identified anatomical landmarks in the image.

12. The system of claim 11 , wherein the processor is further programmed to:

determine whether the location is the destination site.

13. The system of claim 12 , wherein the processor is further programmed to:

send a visual indicator to the display when the location has been determined to be the destination site.

14. The system of claim 13 , wherein the visual indicator is color coded.

15. The system of claim 9 , wherein the processor is further programmed to:

determine an orientation of the embolic protection device with respect to anatomical landmarks using the processed intravascular ultrasound imaging signal.

16. The system of claim 9 , wherein the processor is further programmed to:

generate instructions for adjusting the position of the embolic protection device based on the determined orientation of the embolic protection device.

17. A system for providing embolic protection, the system comprising:

an embolic protection device comprising:

a guidewire having a proximal end, and a distal end;

a first sheath having a proximal end, a distal end and a lumen, the lumen configured to receive the guidewire;

a first distal protection filter attached to a distal portion of the first sheath;

a second sheath having a proximal end, a distal end and a lumen, the second sheath disposed over the first sheath, wherein the distal end of the second sheath is located proximally the first distal protection filter;

a second distal protection filter attached to a distal portion of the second sheath;

an outer sheath disposed over both the first sheath and the second sheath; and

an intravascular ultrasound transducer disposed on an atraumatic tip, the atraumatic tip extending from the distal end of the first sheath.

a user interface configured to receive input from an operator regarding a surgical procedure including an insertion site and a destination site;

a display;

a processor programmed to:

receive input from the user interface regarding the surgical procedure;

determine anatomical landmarks between the insertion site and the destination site;

receive an intravascular ultrasound signal from the intravascular ultrasound transducer;

process the intravascular ultrasound signal into an image; and

send the image to the display.
