    摘要： An implantable occlusion device for bridging the neck of an aneurysm comprises a biocompatible matrix. The device is movable between a compressed position prior to implantation and a generally concave or cup-shaped position following implantation. The device may comprise a frame having a plurality of elements. The frame elements have a first pre-deployment position generally parallel to a major axis of the delivery lumen, and a second post-deployment position spread radially from the major axis of the delivery lumen. The biocompatible matrix and/or the frame elements may also form or be manipulated to form a generally concave or cupped shape. The matrix can be porous or semiporous, such as a foam or a reticulated matrix. The occlusion device can be folded, twisted and/or stretched to adopt a narrow profile for loading into a coaxial delivery device and expand in place as it adopts its original shape on release. The device may be released or manipulated to a desired shape to occlude an aneurysm. Methods of using the implantable device are also provided.

    摘要： The self-expandable endovascular apparatus for aneurysm occlusion of the invention comprises a deformable shape memory frame with at least a partial segment covering comprised of a matrix implant material. The device can be folded and/or stretched to adopt a narrow profile for loading into a coaxial delivery device and expands in place as it adopts its original shape on release from the device into an aneurysm. A method of treating an aneurysm, comprises the steps of: (a) providing the self-expandable endovascular apparatus inserted into a lumen of a delivery device comprising a proximal end and a distal end, the distal end having a distal tip; (b) advancing the distal tip of the delivery device into an opening in an aneurysm having an interior sac; (c) advancing the apparatus through the lumen into the opening; and (d) withdrawing the delivery device, whereby the apparatus expands into the sac and covers the opening.
