Methods and devices for occluding body lumens and/or enhancing tissue ingrowth
First Claim
1. An occlusive device, said device comprising:
- a first element constructed of a first metallic material; and
a second element constructed of a second metallic material, said first metallic material is different than said second metallic material, said first and second elements being electrically separated from each other along at least a significant portion of said elements.

Abstract
The present invention provides devices, methods and systems for the occlusion of various lumens in a body of a patient including devices and methods for enhancing tissue ingrowth, particularly endothelial tissue growth within an occlusive device. The system includes an occlusive device and a delivery device for placing the occlusive device in a body lumen. The occlusive device is generally a tubular member with a mesh member disposed thereon. The occlusive device is configured to be radially expandable along a longitudinal axis of the tubular member and implantable with a delivery catheter such that the occlusive device is in a collapsed state when positioned in the delivery catheter and in an expanded state when positioned in a lumen of a patient. The mesh member of the occlusive device is configured to promote epithelial tissue ingrowth.

12. A delivery catheter system for delivering an occlusive device into a body lumen comprising:
-
a tissue abrading distal tip portion comprising an abrasive portion of the outer wall of the distal end of the catheter; and
a pusher device for holding the occlusive device relative stationary in a longitudinal direction while the catheter is withdrawn which acts to expel the occlusive device from the catheter delivery lumen. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

20. A delivery catheter system for delivering an occlusive device, said system comprising:
-
a catheter shaft;
a pusher wire contained within at least a portion of said catheter shaft, said pusher wire fixedly attached to said catheter handle; and
a handle having a sliding member and a catheter clasping member, said catheter clasping member attached to said sliding handle and to said catheter shaft such that moving said sliding member relative to said catheter handle serves to move said catheter shaft relative to said pusher wire. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28)

29. A delivery catheter comprising a catheter delivery lumen having a distal cone, said distal cone having a first, closed configuration and a second open configuration, said distal cone biased in the direction of said first, closed configuration, said distal cone being moved from said first closed configuration to said second, open configuration by movement of an occlusive device through said delivery lumen and out the distal end of said lumen, through the distal cone.
-
30. An occlusive device comprising:
a plurality of segments, said segments joined to the longitudinally adjacent segment by a flexible joining element such that not all the longitudinal force applied to one element is transmitted to the adjacent element.
-
31. An immediately effective occlusive device, the device comprising:
-
a barrier device, said barrier device substantially impermeable to the passage of cells within said body lumen; and
a scaffold device, said scaffold device permitting tissue ingrowth from the walls of said body lumen into said scaffold device such that an occlusion of said body lumen occurs when said tissue ingrowth has substantially occurred, and said scaffold device attached to said barrier device such that placement of said scaffold device into said body lumen places said barrier device and positions it in such a manner as to accomplish substantially complete occlusion of said body lumen. - View Dependent Claims (32, 33, 34, 35, 36)
