Abstract

Occlusion-removing devices (10) that include an inflatable balloon (15) for arresting blood flow and a occlusion-shearing element (14) are provided. The device includes a housing element (11) with lumens and an embolism collector (12) and cutting element (14). Also provided are methods for making and usin g these devices.

Claims (21)

1. A device for removing occlusions from a vessel, comprising a housing element having a distal end, a proximal end and a longitudinal axis, wherein one or more lumens are disposed along the longitudinal axis;
an embolism collector element;
a cutting element attached to the distal end of the drive shaft; and an inflatable balloon.
2. The device of claim 1, further comprising a fluid channel in operable communication with the cutting element.
3. The device of claim 1 or 2, further comprising a casing disposed around cutting element.
4. The device of any of claims 1 to 3, further comprising a drive shaft disposed along the longitudinal axis of the housing.
5. The device of any of claims 1 to 4, further comprising a power source connected to the cutting element.
6. The device of claim 5, wherein the power source comprises a micro electro mechanical system (MEMS) motor.
7. The device of any of claims 1 to 6, wherein the embolism collector element is disposed along the longitudinal axis of the housing.
8. The device of claim 7, wherein the collector element comprises a vacuum aspirator.
9. The device of any of claims 1 to 8, wherein the surface of the cutting element is not smooth.
10. The device of any of claims 1 to 9, wherein the cutting element further comprises perforations therein.
11. The device of any of claims 1 to 10, wherein the lumen of the housing which contacts the cutting element is surface-modified.
12. The device of any of claims 3 to 11, wherein the surface of the casing surrounding the cutting element is surface-modified.
13. The device of claim 11 or claim 12, wherein the surface modification comprises braiding or ribbons.
14. The device of any of claims 3 to 13, wherein the casing extends from the distal end of the housing.
15. The device of any of claims 3 to 14, wherein the casing comprises a cage-like structure.
16. The device of any of claims 1 to 15, wherein the inflatable balloon is capable of centering the cutting element.
17. The device of any of claims 1 to 15, wherein the inflatable balloon is capable of at least partially arresting blood flow around the occlusion.
18. A method of removing an occlusion in a vessel, comprising accessing a selected site with the device according to any of claims 1 to 17;
inflating the balloon to the desired dimensions;
shearing at least a portion of the embolism with the cutting element; and removing the sheared fragments of the embolism with the collection element.
19. The method of claim 18, wherein the shearing comprises:
drawing a portion of the embolism into the housing and manipulating the cutting element to shear the embolism against the interior wall of the housing.
20. The method of claim 18 or 19, wherein the device further comprises a casing disposed around the cutting element.
21. The method of claim 20, wherein the shearing comprises extending the cutting element and surrounding casing from the distal end of the housing and manipulating the cutting element against the casing.
