摘要： Described here are methods and apparatuses for tracking a clot material within a lumen of a suction catheter. For example, an apparatus as described herein may include a flexible elongate body having a suction lumen, a first pair of electrodes within the suction lumen, a second pair of electrodes proximal to the first pair of electrodes, and a controller configured to track a clot material within the suction lumen based on signals from the first pair of electrodes and the second pair of electrodes.

摘要： Methods for removing clot material by directional aspiration may include removing clot material from a side vessel while the suction catheter remains in the main vessel. These methods may include a steerable distal end region. In some cases the apparatuses and methods may include the use of a guide catheter and/or a guidewire in orienting the suction catheter to laterally capture clot material from a side vessel without having to enter the side vessel. Any of these methods may include optionally sensing and confirming clot material (e.g., electrically sensing).

摘要： Apparatuses and methods for distinguishing a blood clot from a vessel wall. These methods and apparatuses may include an aspiration opening into a suction lumen, an aspiration opening sensor(s) positioned at a rim of the aspiration opening, and a controller that interprets signals from the aspiration opening sensor(s) to determine when the aspiration opening is contacting a clot material or a vessel when a force is applied.
