1. A occlusion device comprising:
- a cylindrical compressible elastomeric matrix member having a proximal end and a distal end and having a lumen extending therethrough;
one or more compression members arranged in the compressible elastomeric matrix member to define one or more cylindrical sections;
a distal spring coil attached to the distal end of the compressible elastomeric matrix member; and
a proximal spring coil attached to the proximal end of the compressible elastomeric matrix member, wherein the device assumes a non-linear shape.

Abstract
An aneurysm treatment device for in situ treatment of aneurysms comprises a collapsible member having a first shape wherein the first shape is an expanded geometric configuration, and a second shape, wherein the second shape is a collapsed configuration that is loadable into a catheter. The aneurysm treatment device is capable of returning to the first shape in the sac of an aneurysm upon deployment, where it occludes the aneurysm.

- 28. An occlusion device which comprises a longitudinal compressible elastomeric matrix member having one or more radiopaque markers that define two or more sections of the reticulated elastomeric matrix member in the longitudinal direction, wherein a flexible suture or wire extends longitudinally through the reticulated elastomeric matrix member.
- 31. An occlusion device which comprises a multitude of longitudinally extending compressible elastomeric matrix members that are intertwined and have one or more radiopaque markers that define sections of the device in the longitudinal direction.
- 34. An occlusion device which comprises a square or rectangular essentially flat compressible elastomeric matrix member that has sutures and/or radiopaque markers extending along the edges thereof and/or diagonally.
- 37. An occlusion device which comprises a wire structure covered by compressible elastomeric matrix wherein the wire structure comprises regularly spaced sections that are attached at a single point and the structure compresses to an essentially flat structure but expands to a regularly spaced structure when pressure is released.
- 40. An occlusion device which comprises a cylindrically shaped wire structure comprising compressible elastomeric matrix and having lateral slots.
