Abstract: A target substance, such as a thrombus, is removed from a patient's body via minimally invasive technique. A catheter is maneuvered and positioned near the target substance. The catheter may have a soft, atraumatic tip constructed from a metallic backbone covered by a polymer. Target substances are drawn into the catheter via an aspiration source. Near the catheter's distal end, a blade and opposing surface are housed within the catheter, and the blade moves relative to the opposing surface within the catheter lumen in order to fragment the target substance. The substances are fragmented within the catheter into discreet and relatively uniform particles. The aspiration source, which helps ensnare target substances, also serves to evacuate the substance fragments from the patient's body.

Abstract: A platform of computing systems is configured to receive thrombectomy procedure data that is associated with a user of an aspiration thrombectomy system. The procedure data includes sets of temporal datapoints associated with a thrombectomy procedure. The platform of computing systems is further configured to generate thrombectomy analytics data based on baseline procedure data and the sets of datapoints. The platform of computing systems is further configured to visually display the thrombectomy analytics data, and to provide comparative data metrics for selection on an interactive interface.

Abstract: An aspiration thrombectomy system includes an aspiration catheter configured to accommodate fluid and having a proximal end and a distal end. The system includes connection tubing coupled to the aspiration catheter and configured to act as a common conduit for fluid communication. The system further includes controllable valves operable to control a level of pressure, and pressure sensors positioned downstream from the distal end of the aspiration catheter. A controller is configured to detect and identify pressure levels associated with an open flow state of the aspiration thrombectomy system, and to determine a vascular pressure level of the patient.
