Abstract: Aspiration thrombectomy devices and methods wherein an aspiration cycle includes a positive displacement segment to facilitate clot removal, a pump cartridge to facilitate tube management and an aspiration device for providing a vacuum surge. Disclosed herein is an aspiration thrombectomy system which relies on air or inert gas, rather than liquid, to provide both static and dynamic suction level profiles for safely and efficiently retrieving and removing from the body a thrombus. In one example embodiment, two or more pressure sources may be configured to apply two or more suction levels to an aspiration catheter. Valves may connect conduits between the pressure sources and the aspiration catheter, with the valves being selectively opened or closed to control which pressure level is applied to the catheter.

Abstract: The present disclosure relates to medical devices including occlusion devices, clot retrieval systems, and stents. More particularly, the medical devices described herein measure characteristics for intravascular treatment sites. The medical devices may include pressure sensors and/or length sensors that may be used to determine the effectiveness of the medical devices during or after treatment. These sensors may be particularly helpful when used on an occlusion device or a clot removal device.

Abstract: Embolic coils with detachable segments that are separated by detachment capsules that are thermolytically degradable such that varying lengths of coil may be implanted into a vascular malformation to occlude same. The capsules are radiotransparent when compared to the adjoining coil segments to the location of the segments is easily seen. The capsules further include protruding electrical contacts that make positive contact with terminals on a delivery catheter. The terminals on the delivery catheter serve as markers so the relationship between the detachment capsules and the terminals is easily visible under x-ray.
