Temporary intraluminal filter

摘要

The present invention is a intraluminal filter for use during interventional procedures, such as angioplasty or stent deployment. A braided filter (25) is mounted near the distal end of a steerable guidewire (20), which guides a therapeutic catheter (10). An actuator rod (180) slides over the guidewire and is removably connected to the filter. The rod controls relative displacement of the filter ends, causing transformation of the filter between a deployed configuration and a collapsed configuration. Wire (24) having enhanced radio-pacity is included in the filter to provide visualization under fluoroscopy.The present invention is a intraluminal filter for use during interventional procedures, such as angioplasty or stent deployment.
