Abstract

The present invention generally relates to medical devices, and more particularly to an improved intravascular intervention device. In one embodiment, an intravascular intervention device includes a microcatheter configured for intravascular delivery, an imaging wire received within the microcatheter, and a treatment device received within the microcatheter, wherein the imaging wire and the treatment device may be simultaneously advanced. The treatment device is configured to perform intravascular intervention. For example, the treatment device may be configured to deliver a stent, an embolic coil and/or a thrombolytic agent. In this embodiment, the intravascular intervention device may image the area of interest while performing the intravascular intervention, thus allowing imaging to take place in real time.

Claims

15. An intravascular intervention system, comprising:

an intravascular device comprising

a microcatheter configured to fit in a patient'"'"'s neurovasculature;

an imaging wire received within the microcatheter; and

a treatment device received within the microcatheter, wherein the imaging wire and the treatment device may be simultaneously advanced within the microcatheter; and

a processor coupled to the imaging wire configured to process signals generated by the imaging wire.

16. The system of claim 15, wherein the microcatheter includes a sheath having a lumen configured to receive the imaging wire and the treatment device.

17. The system of claim 15, wherein the microcatheter includes a sheath having first and second lumens, wherein each lumen is configured to receive one of the imaging wire and the treatment device.

18. The system of claim 15, wherein the imaging wire includes a sheath and a floppy tip coupled to the distal end of the sheath.

19. The system of claim 18, wherein the sheath defines a puncture hole towards the distal end of the sheath.

20. The system of claim 18, wherein the imaging wire includes an imaging transducer assembly received within the sheath of the imaging wire.

21. The system of claim 20, wherein the imaging transducer assembly is translatable within the sheath of the imaging wire.

22. The system of claim 21, wherein the imaging wire further includes a drive shaft proximally coupled to the imaging transducer assembly.

23. The system of claim 22, wherein the drive shaft comprises of a wound coil.

24. The system of claim 23, wherein the drive shaft comprises of a laser cut Nitinol tube.

25. The system of claim 22, wherein the drive shaft comprises of a counterwound coaxial cable.

26. The device of claim 15, wherein the treatment device is configured to deliver a vaso-occlusive coil.

27. The device of claim 15, wherein the treatment device is configured to deliver a treatment drug.

28. The device of claim 15, wherein the treatment device is configured to deliver a stent.

29. A method for treating a disorder located in a neurovascular vessel, comprising the steps of:

advancing a microcatheter into an area of interest within the neurovascular vessel;

advancing an imaging wire to an area beyond the distal end of the microcatheter;

performing intervention at the area of interest; and

imaging the area of interest during the intervention.

1. An intravascular intervention device comprising:

a microcatheter configured to fit in a patient'"'"'s neurovasculature;

an imaging wire received within the microcatheter; and

a treatment device received within the microcatheter, the treatment device being adapted to apply treatment to the neurovasculature, wherein the imaging wire and the treatment device may be simultaneously advanced within the microcatheter.

2. The device of claim 1, wherein the microcatheter includes a sheath having a lumen configured to receive the imaging wire and the treatment device.

3. The device of claim 1, wherein the microcatheter includes a sheath having first and second lumens, wherein each lumen is configured to receive one of the imaging wire and the treatment device.

4. The device of claim 1, wherein the imaging wire includes a sheath and a floppy tip coupled to the distal end of the sheath.

5. The device of claim 4, wherein the sheath defines a vent hole towards the distal end of the sheath.

6. The device of claim 4, wherein the imaging wire includes an imaging transducer assembly received within the sheath of the imaging wire.

7. The device of claim 6, wherein the imaging transducer assembly is translatable within the sheath of the imaging wire.

8. The device of claim 7, wherein the imaging wire further includes a drive shaft proximally coupled to the imaging transducer assembly.

9. The device of claim 8, wherein the drive shaft comprises of a wound coil.
