Abstract

Medical devices for revascularization and methods of their use are disclosed. The medical device includes an actuator portion, an inner tubular body connected to the actuator portion and an outer tubular body connected to the actuator portion. The inner tubular body is disposed within a bore of the outer tubular body. The medical device also includes a guide wire extending through one or more of the actuator portion, inner tubular body and outer tubular body.

Claims

1. A medical device, comprising:

an actuator portion;

an inner tubular body connected to the actuator portion;

an outer tubular body connected to the actuator portion, wherein the inner tubular body is disposed within a bore of the outer tubular body; and

a guide wire extending through one or more of the actuator portion, inner tubular body and outer tubular body.

2. The medical device according to claim 1, wherein the actuator portion provides

means for manipulating an orientation of the inner tubular body relative to one or more of the outer tubular body and guide wire for penetrating a blockage within a vessel for revascularizing the vessel.

3. The medical device according to claim 2, wherein the manipulation of the orientation of the inner tubular body is a single, forceful plunging movement through the blockage, wherein the blockage includes a chronic total occlusion or partial occlusion, and wherein the vessel includes an artery.

4. The medical device according to claim 1, wherein the inner tubular body includes a distal end that provides

means for penetrating a blockage within a vessel for revascularizing the vessel in response to a manipulation of the actuator portion.

5. The medical device according to claim 4, wherein the penetrating the blockage within the vessel is conducted by a single, forceful plunging movement of the inner tubular body through the blockage, wherein the blockage includes a chronic total occlusion or partial occlusion, and wherein the vessel is an artery.

6. The medical device according to claim 4, wherein a bore of the inner tubular body is connected to an aspiration device.

7. The medical device according to claim 4, wherein a distal end of the inner tubular body includes a piercing portion.

8. The medical device according to claim 7, wherein the piercing portion forms an opening at the distal end of the inner tubular body, and wherein a bore of the inner tubular body is connected to an aspiration device for aspirating a portion of the blockage out of the vessel.

9. The medical device according to claim 1, wherein the actuator portion includes

a deployment actuator,

a selectively releasable fastener connected to the deployment actuator,

a deployment actuator reset member connectable with the selectively releasable fastener, and

an energy storage member connected to the deployment actuator reset member.

10. The medical device according to claim 9, wherein the deployment actuator member includes a depressible button, wherein the selectively releasable fastener includes a latch, wherein the deployment actuator reset member includes a lever, wherein the energy storage member includes a spring.

11. The medical device according to claim 9, wherein the distal end of the inner tubular body further comprises a piercing portion.

12. The medical device according to claim 11, further comprising an inflatable portion connected to an outer surface of the outer tubular body.

13. The medical device according to claim 1, wherein the inner tubular body is detachably connected to the actuator portion.

14. The medical device according to claim 1, further comprising an inflatable portion.

15. A method of revascularizing a totally occluded or partially occluded vessel containing at least one blockage, comprising:

providing a revascularization device comprising

an actuator portion;

an inner tubular body connected to the actuator portion, wherein the inner tubular body comprises a distal end;

an outer tubular body connected to the actuator portion, wherein the inner tubular body is disposed within a bore of the outer tubular body; and

a guide wire extending through one or more of the actuator portion, inner tubular body and outer tubular body.

16. The method of claim 15, further comprising

locating the distal end of the inner tubular body proximate to the at least one blockage in the vessel;

and

manipulating the actuator portion so that the distal end of the inner tubular body penetrates the blockage.

17. The method of claim 16, wherein the revascularization device further comprises an inflatable portion, and wherein the method further comprises inflating the inflatable portion.

18. A method of revascularizing a totally occluded or partially occluded vessel, comprising:

providing a revascularization device comprising

an actuator portion;

an inner tubular body detachably connected to the actuator portion, wherein the inner tubular body comprises a distal end;

manipulating the actuator portion so that the distal end of the inner tubular body penetrates the blockage, creating a bore through the blockage;

detaching the inner tubular body; and

attaching a medical interventional device to the actuator portion.

19. The method of claim 18, wherein the medical interventional device comprises a stent attached thereto;

and the method further comprises placing the stent at least partially within the bore through the blockage by manipulating the actuator portion.

20. The method of claim 18, wherein the revascularization device further comprises an inflatable portion, and the method further comprises inflating the inflatable portion.
