PROBLEM TO BE SOLVED: To provide intravascular devices and more particularly implantable filter devices arranged within the vena cava for capturing dislodged blood clots or debris.SOLUTION: The present invention provides, in one embodiment, a vascular filter device for capturing dislodged blood clots within a vessel. The vascular filter device includes an expandable framework for securing the device within a vessel. The device also includes a pathway extending through the framework. The device further includes at least one filter in alignment with the pathway for capturing dislodged clots or emboli. In an embodiment, the filter can be given form by a material that can be easily eliminated in situ to permit reestablishment of the pathway. |
