    Abstract: Systems and devices with an implantable, intravascular filter for preventing emboli from traveling into brain and causing a stroke or transient ischemic attack are disclosed. In particular, an implantable, intravascular device having a filter element, a pressure sensor, and a valve is disclosed. The valve is biased into a closed configuration and changes into an open configuration upon a predetermined pressure drop across the filter. Systems comprising an external device at least one implantable device are also disclosed.

    Abstract: An intravascular filter device having a flexible arm which comprises a portion of an alarm system for detecting filling or plugging of the filter by captured emboli is described. The flexible arm may be made of ferromagnetic material, a magnet, or have at its tip a magnet which, as it moves under systolic and diastolic pressures, generates a signal detectable by an electrical sensor or a magnetometer. The signals from each of a pair of artery filters may be measured and compared to determine whether one filter is plugged. A system for detection and a method of use are also provided.

    Abstract: An intraluminal filtration device for embolic protection includes a device body and each of a coarse filter and a fine filter, for filtering larger-size and smaller-size particles, respectively. The device body includes a body wall extending circumferentially around the longitudinal axis, and being formed at least in part of an organic gel.
