Abstract: 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.

Abstract: Described herein are methods and apparatuses for detecting an obstructive material within a lumen of an aspiration catheter using one or more sensors with the lumen of the suction catheter to prevent excess blood loss and improve operation of the apparatus.

Abstract: According to some embodiments, the present technology includes a device for the disruption and/or removal of obstructive material in a blood vessel. The device can comprise an elongated shaft having a proximal portion, a distal portion, and a lumen extending therebetween. The device can further comprise a capture structure carried by the distal portion of the elongated shaft and having a greater cross-sectional dimension than a cross-sectional dimension of the elongated shaft. The capture structure can comprise an opening at a first end portion that is fluidly coupled to the lumen of the elongated shaft, a fluid impermeable sidewall enclosing an interior region, and an opening extending through a thickness of the sidewall. A portion of the sidewall surrounding the opening can be configured to deform towards or away from the interior region such that a cross-sectional dimension of the opening increases to receive the obstructive material therethrough.

Abstract: A method of removing exhaled material from a medical procedure field adjacent to a subject's nose and mouth. In some embodiments the method includes the steps of placing an isolation barrier at least partially surrounding the subject's nose and mouth to define the medical procedure field; controlling air flow into the medical procedure field with the isolation barrier; and evacuating air from the medical procedure field at an air evacuation rate greater than or equal to the subject's respiratory minute volume. The invention also provides a system for creating an isolated medical procedure field around a subject's nose and mouth.

Abstract: An isolation barrier and method of using it. The isolation barrier includes a mask with a face opening and at least one access opening in front of the subject's nose and/or mouth and an enclosure having a first enclosure opening attached around the access opening, a second enclosure opening, and flexible material extending from the first enclosure opening to the second enclosure opening and defining an enclosure interior, the flexible material comprising at least one area through which the enclosure interior can be viewed, the mask and enclosure interior defining a medical procedure field extending from the subject's nose and mouth to the second enclosure opening when the isolation barrier is in place on the subject's face.
