Abstract

A tissue puncture locator device includes an anchor assembly and a sealing member. The anchor assembly includes an anchor portion, a tube portion, and a filling member. The anchor portion is positioned at a distal end of the tube portion and configured for placement through a vascular incision into a vessel. The anchor member has an unexpanded configuration that permits passage through the vascular incision and an expanded configuration that limits passage through the vascular incision. The filling member is retained in the tube portion and adapted for insertion from the tube portion into the anchor member to provide the expanded configuration, and adapted for retraction from the anchor member into the tube portion to provide the unexpanded configuration. The sealing member is configured for placement adjacent the vascular incision outside the vessel.

First claim

What is claimed is:

1. A tissue puncture locator device, comprising:
an anchor assembly, including:
a tube portion;
an anchor portion positioned at a distal end of the tube portion and configured for placement through a vascular incision into a vessel, the anchor portion having an unexpanded configuration that permits passage through the vascular incision and an expanded configuration that limits passage through the vascular incision;
a filling member retained in the tube portion and adapted for insertion from the tube portion into the anchor portion to provide the expanded configuration, and adapted for retraction from the anchor portion into the tube portion to provide the unexpanded configuration, the filling member having a random contorted shape configuration collected within the anchor portion, a distal tip of the filling member being movable through a plurality of random proximally and distally extending paths while filling the anchor portion;

a sealing member configured for placement adjacent the vascular incision outside the vessel, the anchor portion being retractable through the sealing member when in the unexpanded configuration.

2. The tissue puncture locator device of claim 1 , wherein the filling member is selected from a group consisting of a wire member, a polymer strand, and a gel strand.

3. The tissue puncture locator device of claim 1 , further comprising a handle portion, the tube portion extending from the handle portion to the anchor portion.

4. The tissue puncture locator device of claim 1 , wherein the sealing member is movable along the tube portion to the placement adjacent the vascular incision.

5. The tissue puncture locator device of claim 1 , wherein the sealing member comprises a collagen material.

6. The tissue puncture locator device of claim 1 , wherein the anchor assembly further includes an actuator configured to move the filling member into the anchor portion and retract the filling member from the anchor portion.

7. A tissue puncture locator device, comprising:
an anchor assembly, including:
a tube portion having a first portion and a second portion, the first portion having a first tubular wall thickness and the second portion having a second tubular wall thickness, the second wall thickness being reduced relative to the first wall thickness, the second portion positioned at a distal end of the tube portion and configured for placement through a vascular incision into a vessel, the second portion having an unexpanded configuration that permits passage of the second portion through the vascular incision and an expanded configuration that limits passage through the vascular incision;
a filling member retained in the first portion of the tube portion and adapted for insertion from the first portion into the second portion to provide the expanded configuration, the filling member adapted for retraction from the second portion into the first portion to provide the unexpanded configuration, the filling member having a random contorted shape configuration collected within the second portion, a distal tip of the filling member being configured to randomly move proximally and distally within the second portion when filling the second portion;

a sealing member configured for placement adjacent the vascular incision outside the vessel, the second portion of the tube portion being retractable through the sealing member when in the unexpanded configuration.

8. The tissue puncture locator device of claim 7 , wherein the anchor assembly further includes an actuator configured to move the filling member into the second portion and to retract the filling member from the second portion.

9. The tissue puncture locator device of claim 7 , wherein the filling member is configured to assume various shapes upon each insertion from the first portion into the second portion.

10. The tissue puncture locator device of claim 7 , wherein the first portion has an inner diameter and the filling member has an outer diameter, the inner diameter being sized between about 100 and about 200 percent of the outer diameter.

11. A tissue puncture locator device, comprising:
an anchor assembly, including:
a tube portion;
an anchor member positioned at a distal end of the tube portion and configured for placement through a vascular incision into a vessel, the anchor member having an unexpanded configuration that permits passage through the vascular incision and an expanded configuration that limits passage through the vascular incision;
a filling member retained in the tube portion in a straight configuration and adapted for insertion from the tube portion into a randomly expanded and collected shape in the anchor member to provide the expanded configuration, a distal end of the filling member being movable through a random proximal and distal movement to reach the expanded configuration, and adapted for retraction from the randomly expanded shape in the anchor member to the straight configuration in the tube portion to provide the unexpanded configuration;

a sealing member configured for placement adjacent the vascular incision outside the vessel, the anchor member being retractable through the sealing member when in the unexpanded configuration.

12. The tissue puncture locator device of claim 11 , wherein the anchor assembly further includes an actuator configured to move the filling member into the anchor member and to retract the filling member from the anchor member.

13. The tissue puncture locator device of claim 11 , wherein the filling member is configured to assume various different shapes upon each insertion from the tube portion into the anchor member.

14. The tissue puncture locator device of claim 11 , wherein the tube portion has an inner diameter and the filling member has an outer diameter, the inner diameter being sized between about 100 and about 200 percent of the outer diameter.

15. A tissue puncture locator device, comprising:
an anchor assembly, including:
a tube portion having a first portion and a second portion, the first portion having a first tubular wall thickness and the second portion having a second tubular wall thickness, the second wall thickness being reduced relative to the first wall thickness, the second portion positioned at a distal end of the tube portion and configured for placement through a vascular incision into a vessel, the second portion having an unexpanded configuration that permits passage of the second portion through the vascular incision and an expanded configuration that limits passage through the vascular incision;
a filling member retained in the first portion of the tube portion and adapted for insertion from the first portion into the second portion to provide the expanded configuration, the filling member adapted for retraction from the second portion into the first portion to provide the unexpanded configuration, the filling member having a random contorted shape configuration within the second portion;

a sealing member configured for placement adjacent the vascular incision outside the vessel, the second portion of the tube portion being retractable through the sealing member when in the unexpanded configuration;
wherein the first portion has an inner diameter and the filling member has an outer diameter, the inner diameter being sized between about 100 and about 200 percent of the outer diameter.

16. A tissue puncture locator device, comprising:
an anchor assembly, including:
a tube portion;
an anchor member positioned at a distal end of the tube portion and configured for placement through a vascular incision into a vess
