Abstract

Wires, catheters, endoscopes, etc. and their methods that have flow directed distal ends, which allow and facilitate management of these devices during use are disclosed. Additionally instant invention allows for distal anchoring so that the device will remain in a location once it has arrived and its method for use. Further, the instant invention describes an apparatus and method for a tensioning characteristic to be applied along the device once it is place that will facilitate the passing of another member along the initially placed member. Last, a novel occluder is disclosed and its method of use.

Claims

1. An improved medical device for use in the body, comprising:

a support wire insertable into the body, said wire having a distal end,

an expanding element supported on said distal end of said wire, said support wire having a radially compressed state for insertion of said wire into the body,

expansion of said expanding element when positioned in the desired location of the body for anchoring.

2. The device of claim 1 wherein:

said device is used for anchoring within the tubular channels of the body.

3. The device of claim 1, wherein:

said device is used for tensioning within the tubular channels of the body.

4. The device of claim 1, wherein:

said device is used for tubular channel occlusion when support wire is removed.

5. The medical device of claim 1 wherein:

said expandable element is used with the flow in the tubular channels of the body.

6. The medical device of claim 1 wherein:

said expanding element is an annular braided segment.

7. The device of claim 1 wherein said expanding element in said expanded state contacts the wall of the passageway in which it is inserted.

8. The device of claim 6 wherein:

said annular braided segment is coated with a membrane.

9. The device of claim 1 wherein:

said expansion element is a braided element having individual yarns sufficiently flexible to be moved between said states and sufficiently stiff to substantially hold said expanded state when in the targeted area within the body.

10. The device of claim 1, wherein said blocking mechanism is a multi-wing malecot having an annular elastomeric film around said wings.

11. The method of claim 1, comprising the steps of placing the apparatus in the body.

12. A method of claim 11, wherein the expanding mechanism is an annular braid.

13. A method of claim 11, wherein the expanding mechanism is a multi-winged malecot style mechanism with a thin membrane at least between the two of the wings.

14. A method of claim 1, wherein the expanding mechanism is used to anchor the device.

15. A method of claim 1, wherein the expanding mechanism is used to anchor matter within the body.

16. A method of claim 1, wherein the expanding mechanism is used as a flow director.

17. A method of claim 1, wherein the expanding mechanism is used to apply tension to the shaft of the device.

18. A method of claim 1, wherein the expanding mechanism is used a tubular channel occluder.
