摘要:
An occlusion device includes a tubular expandable body with a frame that has a plurality of interconnected members configured to expand within a body vessel and to collapse for delivery or retrieval of the device. The occlusion device further includes a hydrophilic polyurethane hydrogel layer attached to the interconnected members of the tubular expandable body. The polyurethane hydrogel layer expands upon exposure to an aqueous environment.
