Thin Film Metallic Device for Plugging Aneurysms or Vessels
First Claim
1. A thin film occlusion device for occluding at least a portion of a body vessel in a human subject, comprising:
- a distal end portion having a substantially closed end configuration;
a proximal end portion;
a body portion extending between said distal end portion and said proximal end portion; and
a plurality of slot members associated with at least a selected one of said body portion, distal end portion, and proximal end portion, wherein said slot members are in a generally open condition when the occlusion device is in a collapsed orientation suitable for passage through a medical delivery apparatus, and wherein said slot members are in a generally closed condition with radial expansion movement of the occlusion device to a deployed orientation for occlusion action within a body vessel.

Abstract
Thin film metallic devices implantable within a human subject for occlusion of an aneurysm or blood vessel are provided. The devices are movable from a porous, elongated, collapsed configuration for delivery to a deployed configuration within the body. The pores telescope as the device moves to its deployed configuration, which causes the device to longitudinally foreshorten and radially expand, while also decreasing in porosity for preventing blood flow. The occlusion devices may be either self-supporting or supported by a strut structure. Additionally, the occlusion devices may comprise a plurality of layers having unaligned pore systems which further reduce porosity in the deployed configuration.

9. A thin film occlusion device for occluding at least apportion of a body vessel in a human subject, comprising:
-
a distal end portion having a substantially closed end configuration;
a proximal end portion;
a body portion extending between said distal end portion and said proximal end portion; and
a plurality of pores associated with at least a selected one of said distal end portion, proximal end portion, and body portion, wherein the occlusion device is movable between a collapsed orientation for delivery by a medical implantation apparatus and a radially expanded deployed orientation within a body vessel, and wherein the porosity of at least the selected one of said distal end portion, proximal end portion, and body portion is greater in said collapsed orientation than in said deployed orientation. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A thin film occlusion device for occluding at least a portion of a body vessel in a human subject, comprising:
-
a distal end portion having a substantially closed end configuration;
a proximal end portion having a substantially closed end configuration;
a body portion extending between said distal end portion and said proximal end portion; and
a plurality of pores associated with said distal end portion and said proximal end portion, wherein said pores are capable of movement from a generally open condition to a generally closed condition and wherein the movement causes at least said distal end portion and said proximal end portion to longitudinally foreshorten and radially expand. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23)
