Abstract

A tissue puncture locator device includes a temporary anchor configured for placement through a vascular puncture into a vessel. The temporary anchor includes a column member that defines a lumen. The temporary anchor is movable between an uncompressed position and a compressed position, wherein in the compressed poition a portion of the column member protrudes radially outward. The column member may include a reduced thickness portion, wherein the column member protrudes radially outward at the reduced thickness portion. The column member, when expanded radially outward within the vessel, is sized to limit retraction of the temporary anchor through the vascular puncture.

First claim

What is claimed is:

1. A tissue puncture locator device, comprising:
a temporary anchor member configured for placement through a vascular puncture into a vessel, the temporary anchor member including a column member that defines a lumen, the column member having a reduced thickness portion, the reduced thickness portion having an outer surface that is continuous around a circumference of the reduced thickness portion at the lumen, the outer surface comprising a plurality of outer recesses along a length of the column member, the reduced thickness portion having an inner surface with an inner recess, the temporary anchor member being movable between an uncompressed position and a compressed position;
wherein in the compressed position the outer surface at the circumference expands radially outward within the vessel to a maximum diameter that limits retraction of the temporary anchor member through the vascular puncture, wherein in the compressed position the plurality of outer recesses of the outer surface flatten into a single radially expanded outer surface at the maximum diameter, the single radially expanded outer surface being continuous around the circumference at the maximum diameter.

2. The tissue puncture locator device of claim 1 , further comprising a compression member adapted for operation outside of a patient to move the temporary anchor member between the uncompressed and compressed positions.

3. The tissue puncture locator device of claim 1 , wherein the column member comprises an elastic material.

4. The tissue puncture locator device of claim 1 , wherein the column member comprises a polymer material.

5. The tissue puncture locator device of claim 1 , wherein the uncompressed position permits passage of the temporary anchor member through the vascular puncture.

6. The tissue puncture locator device of claim 5 , further comprising a sealing member configured for placement adjacent to the vascular puncture along an outer surface of the vessel, wherein the uncompressed position permits passage of the temporary anchor member through the sealing member after placement of the sealing member adjacent to the vascular puncture.

7. The tissue puncture locator device of claim 1 , wherein the inner recess is a concave recess.

8. The tissue puncture locator device of claim 7 , wherein the concave recess is annular.

9. The tissue puncture locator device of claim 1 , wherein at least one of the outer recesses is annular.

10. The tissue puncture locator device of claim 1 , wherein the reduced thickness portion is molded into the column member.

11. A tissue puncture closure device adapted for partial insertion into and sealing of a tissue puncture in an internal tissue wall accessible through a percutaneous incision, the device comprising:
a temporary anchor configured to be disposed on a distal side of the internal tissue wall, the temporary anchor including a column structure and a lumen extending through the column structure, the column structure having a reduced wall thickness portion around the lumen at a location along a length of the column structure, the reduced wall thickness portion having an outer surface that is continuous around a circumference of the reduced wall thickness portion, the outer surface having a plurality of adjacent outer surface recesses along the length of the column structure, the column structure having an internal surface and an internal surface recess formed in the internal surface, the temporary anchor having a compressed state wherein the outer surface at the circumference expands radially outward in a manner flattening and substantially eliminating the plurality of adjacent outer surface recesses into a single radially expanded outer surface configured to limit movement through the vascular puncture, the single radially expanded outer surface having a continuous maximum outer circumference around the lumen, the temporary anchor having an uncompressed state wherein the temporary anchor is configured to move through the tissue puncture.

12. The tissue puncture closure device of claim 11 , wherein the lumen extends along at least a portion of the length of the column structure.

13. The tissue puncture closure device of claim 11 , further comprising a compression member arranged and configured to move the temporary anchor between the compressed and uncompressed states.

14. The tissue puncture closure device of claim 11 , wherein the temporary anchor is configured to occlude blood flow through the tissue puncture when in the compressed state.

15. A method of locating a tissue puncture in an internal tissue through a percutaneous incision using a temporary anchor, the method comprising:
inserting the temporary anchor into the percutaneous incision, the temporary anchor comprising a hollow cylindrical member, the hollow cylindricial member comprising an outer surface, an inner surface, a lumen, and a length, the length comprising a reduced thickness portion and a plurality of out recesses positioned on the outer surface along the length, the outer surface having a continuous circumference at the reduced thickness portion, the circumference extending around the lumen, the inner surface having an inner recess;
applying an axially directed force to the temporary anchor that radially expands the outer surface at the circumference, the plurality of the outer recesses flattening into a radially expanded outer surface and being substantially eliminated at the circumference when the outer surface is expanded;
retracting the temporary anchor proximally until the radially expanded outer surface of the hollow cylindrical member contacts the internal tissur wall adjacent the tissue punture.

16. The method of claim 15 , wherein applying the axially directed force includes applying a compression force to the temporary anchor in a distal direction.

17. The method of claim 15 , wherein the inner recess is molded into the hollow cylindrical member.

18. A tissue puncture locator device, comprising:
a temporary anchor member configured for placement through a vascular puncture into a vessel, the temporary anchor member including a column member that defines a lumen, the column member having a reduced thickness portion, the reduced thickness portion having an outer surface that is continuous around a circumference of the reduced thickness portion, the outer surface comprising a plurality of outer recesses along a length of the column member, the reduced thickness portion having an inner surface with an inner recess, the temporary anchor member being movable between an uncompressed position and a compressed position, wherein in the compressed position a portion of the column member expands radially outward within the vessel to a size that limits retraction of the temporary anchor member through the vascular puncture, wherein in the compressed position the plurality of outer recesses flatten into a single radially expanded portion;
wherein at least one of the outer recesses is annular.
