Abstract

An intravascular device is provided. The device comprises a sealing member, the member including a mesh material and a gripping element operatively attached to the sealing member, the gripping element operatively adapted to allow a user to position the sealing member to seal a blood vessel. Methods of using the device are also provided.

Claims

1. A medical device for insertion through an opening in a wall of a blood vessel, comprising:

a flexible, elongated gripping element, including a channel formed therein;

a rigid guide including a guide channel receiving the gripping element therein such that a first portion of the gripping element is received within the guide channel and a second portion of the gripping element extends from the guide channel at a proximal end thereof;

a thin sealing member adapted to conform to an interior portion of the wall of the blood vessel without obstructing the blood vessel and operatively attached to an end of the gripping element; and

at least one thread extending through the channel of the gripping element such that a portion of the thread extends from the channel of the gripping element at a proximal end thereof, the thread also operatively attached to the sealing member so that the sealing member collapses as the thread is pulled taut at a point proximal to the rigid guide.

2. The device of claim 1 wherein the sealing member has an oval shape.

3. The device of claim 1 wherein the sealing member is curled to facilitate insertion into the blood vessel.

4. The device of claim 1 wherein the sealing member is thinner near its perimeter than near its center.

5. The device of claim 1 wherein the sealing member has increased stiffness along its length.

6. The device of claim 1 wherein the sealing member is made of a non-biodegradable material.

7. The device of claim 1 wherein the sealing member is made of a deformable sealing material.

8. The device of claim 1 wherein the sealing member comprises at least two membranes, the membranes sealingly connected along their perimeter.

9. The device of claim 8 further comprising:

a supply duct for supply of a fluid into a space between the membranes for inflating and deflating the device.

10. The device of claim 1 wherein the sealing member includes a mesh material.

11. The device of claim 10 wherein the mesh material forms a grid pattern.

12. The device of claim 10 wherein the mesh material comprises a plurality of mesh strands.

13. The device of claim 12 wherein the thread is attached to at least one of the mesh strands.

14. The device of claim 1 wherein the sealing member and the gripping element are formed in one piece.

15. The device of claim 1 wherein the sealing member collapses in a parachute configuration.

16. The device of claim 1 wherein the sealing member collapses to an insertion configuration for insertion into a blood vessel.

17. The device of claim 1 wherein the sealing member changes configuration to a sealing configuration by releasing tension on the thread.
