Abstract

An occlusion device for occluding a body vessel including a first hub having a tubular wall defining a lumen having a longitudinal axis and a second hub disposed distally along the longitudinal axis. A plurality of arcuate members extend between the first hub and the second hub. The arcuate members extend radially away from the longitudinal axis in an open configuration and extend substantially along the longitudinal axis in a closed configuration. A biocompatible material is disposed within a volume defined by the arcuate members to form an occlusive barrier when deployed within the body vessel.

Claims

1. An occlusion device for occluding a body vessel, the occlusion device comprising:

a first hub extending from a proximal end to a distal end along a longitudinal axis;

a second hub extending from a proximal part to a distal part, the second hub being disposed distally from the first hub along the longitudinal axis;

a first plurality of circumferentially spaced arcuate members extending between the first hub and the second hub, each circumferentially spaced arcuate member having a first end adjoining the distal end of the first hub and a second end adjoining the proximal part of the second hub, the members extending radially away from the longitudinal axis in an open configuration and extending substantially along the longitudinal axis in a closed configuration; and

a biocompatible material being disposed within a volume defined by the arcuate members between the distal end of the first hub and the proximal part of the second hub and forming an occlusive barrier that extends radially around the longitudinal axis, the longitudinal axis having a midpoint halfway between the distal end of the first hub and the proximal part of the second hub, the occlusive barrier extending through the volume defined by the arcuate members substantially at the midpoint of the longitudinal axis and lying in a plane that is substantially perpendicular to the longitudinal axis when deployed within the body vessel in the open configuration;

wherein the first and second ends of the circumferentially spaced arcuate members are substantially free of the biocompatible material.

2. The occlusion device of claim 1 wherein the first hub includes a first tubular wall defining a first lumen along the longitudinal axis.

3. The occlusion device of claim 2 wherein the second hub includes a second tubular wall defining a second lumen along the longitudinal axis.

5. The occlusion device of claim 1 wherein at least one of the arcuate members includes at least one anchoring member.

6. The occlusion device of claim 1 wherein the biocompatible material includes an extracellular matrix.

7. The occlusion device of claim 6 wherein the extracellular matrix includes small intestine submucosa.

8. The occlusion device of claim 1 wherein the biocompatible material includes at least one of nylon, rayon, polyester, polytetrafluroethylene, biocompatible polyurethanes, and mixtures thereof.

9. The occlusion device of claim 2 wherein the first tubular wall includes a flange or threads projecting into the first lumen.

14. The occlusion device of claim 1 wherein the biocompatible material forms a disk attached to at least one of the first plurality of members arranged to extend across a diameter of the body vessel.

4. An occlusion device for occluding a body vessel, the occlusion device comprising:

a first hub extending from a proximal end to a distal end along a longitudinal axis;

a second hub extending from a proximal part to a distal part, the second hub being disposed distally from the first hub along the longitudinal axis;

a first plurality of circumferentially spaced arcuate members extending between the first hub and the second hub, each circumferentially spaced arcuate member having a first end adjoining the distal end of the first hub and a second end adjoining the proximal part of the second hub, the members extending radially away from the longitudinal axis in an open configuration and extending substantially along the longitudinal axis in a closed configuration; and

a biocompatible material being disposed within a volume defined by the arcuate members between the distal end of the first hub and the proximal part of the second hub and forming an occlusive barrier that extends radially around the longitudinal axis when deployed within the body vessel in the open configuration, the longitudinal axis having a midpoint halfway between the distal end of the first hub and the proximal part of the second hub, wherein the occlusive barrier is configured as a substantially flat disk attached to at least one of the arcuate members, the substantially flat disk being oriented at an acute angle to the longitudinal axis and passing through the longitudinal axis substantially at the midpoint of the longitudinal axis,

wherein the first and second ends of the circumferentially spaced arcuate members are substantially free of the biocompatible material.

16. The occlusion device of claim 4 wherein the substantially flat disk has an elliptical shape.

10. A delivery assembly for placing and retrieving an occlusion device for occluding a body vessel, the assembly comprising:

an outer sheath having a tubular body extending from a proximal part to a distal part and the tubular body including a sheath lumen extending therethrough;

an inner member extending from a proximal portion to a distal portion, the inner member being disposed within the sheath lumen and configured for axial movement relative to the outer sheath;

the occlusion device being coaxially disposed within the sheath lumen and removably coupled to the distal portion of the inner member and deployable through the distal part of the outer sheath by means of the relative axial movement of the inner member, the occlusion device comprising;

a first hub extending from a proximal end to a distal end along a longitudinal axis;

a second hub extending from a proximal part to a distal part and being disposed distally from the first hub along the longitudinal axis;

a first plurality of circumferentially spaced arcuate members being attached to the first hub and extending distally to the second hub, each circumferentially spaced arcuate member having a first end adjoining the distal end of the first hub and a second end adjoining the proximal part of the second hub, the members extending radially away from the longitudinal axis in an open configuration and extending substantially along the longitudinal axis in a closed configuration; and

a biocompatible material being disposed within a volume defined by the arcuate members between the distal end of the first hub and the proximal part of the second hub and forming an occlusive barrier that extends radially around the longitudinal axis, the longitudinal axis having a midpoint halfway between the distal end of the first hub and the proximal part of the second hub, the occlusive barrier being configured as a substantially flat disk attached to at least one of the arcuate members, the substantially flat disk being oriented at an acute angle to the longitudinal axis and passing through the longitudinal axis substantially at the midpoint of the longitudinal axis,

wherein the first and second ends of the circumferentially spaced arcuate members are substantially free of the biocompatible material.

11. The delivery assembly of claim 10 wherein the biocompatible material includes small intestine submucosa.

12. The delivery assembly of claim 10 wherein the biocompatible material includes at least one of nylon, rayon, polyester, polytetrafluroethylene, biocompatible polyurethanes, and mixtures thereof.

13. The delivery assembly of claim 10 wherein the distal portion of the inner member includes a threaded section and the first hub includes a tubular wall defining a first lumen, the tubular wall having a flange projecting into the first lumen and configured to engage the threaded section.

15. The delivery assembly of claim 10 wherein at least one of the arcuate members includes at least one anchoring member.
