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 translation: 描述了具有柔性臂的血管内过滤器装置，其包括用于检测被捕获的栓塞填充或堵塞过滤器的警报系统的一部分。 柔性臂可以由铁磁材料，磁体制成，或者在其尖端处具有磁体，当其在收缩压和舒张压下移动时，其产生可由电传感器或磁力计检测的信号。 可以测量并比较来自一对动脉过滤器中的每一个的信号以确定是否堵塞一个过滤器。 还提供了用于检测的系统和使用方法。

Abstract: A ureteral stent may comprise an elongate member with an internal-luminal space. The member may have at least one end coiled in a pigtail-shape, a substantially straight portion, and a plurality of side ports wherein the plurality of side ports are located only in the substantially straight portion and are disposed along a spiral or helix where each side port is located radially and longitudinally offset relative to each adjacent side port.
