Abstract: A medical device for capturing emboli from a blood vessel. An example medical device may include an elongated guide member. The elongated guide member may include a proximal end, a distal end, a first conductive lead, and a second conductive lead. The medical device may also include a power source connected to the first conductive lead and the second conductive lead. The medical device may also have a filter having a proximal end and a distal end, wherein the proximal end is coupled to the first and second conductive leads. The activation of the power source may transition the filter from a first compressed shape to a second expanded shape.

Abstract: The disclosure describes an embolic filter and a support structure therefor.

Abstract: The invention provides a medical device delivery system comprising an offset coupling region interposed between an elongated hypotube guide member or catheter and a support segment. The medical device to be delivered is disposed about the support segment and contained and/or constrained within a containment element. The medical device may be released from the containment element by moving an actuation element from a first position to a second position. The offset coupling region allows the actuation element to exit a lumen within the guide member and to engage the containment element in the first position while traveling along a line generally coaxial with the lumen of the guide member.
