Clot retrieval device for removing occlusive clot from a blood vessel
A clot retrieval device for removing an occlusive clot from a blood vessel. The device includes a clot engagement section having a constrained delivery configuration and an expanded deployed configuration, wherein in the expanded deployed configuration. The clot engagement section can include a plurality of peak sections configured to vary contact pressure between the clot and the device along a length of the device; and a plurality of troughs between respective peak sections comprising a clot reception space. Each peak is configured to exert a relatively high compressive force on the clot whereas each trough is configured to exert little or no compressive force on the clot.

INVERTING THROMBECTOMY APPARATUSES AND METHODS OF USE
Described herein are methods using mechanical inverting tube apparatuses to remove clot (e.g., thrombectomy), the apparatuses including an inversion support catheter having an expandable funnel-shaped distal end, and a flexible tube that can be continuously rolled over the funnel-shaped distal end and invert into the inner lumen of the inversion support catheter.
SYSTEMS AND METHODS OF REDUCING IN-HOSPITAL MORTALITY RATE
Method for using a clot retrieval device for treating a clot in a blood vessel for use in the treatment of ischemic stroke to reperfuse an obstructed vessel. Use of the clot retrieval device reducing in-hospital mortality.

SUCTION CATHETER SYSTEMS WITH DESIGNS ALLOWING IMPROVED ASPIRATION AND EVALUATION OF ASPIRATION CONDITION
An aspiration thrombectomy system is described with an aspiration catheter assembly having fittings interfaced with conduit and a pump. The aspiration catheter assembly can include a guide catheter and an aspiration catheter. The aspiration catheter can be positioned into an artery with a distal opening positioned proximal to a clot. The fittings can include a filter for removing thrombus from the aspiration flow. The fittings can include a flow meter for measuring flow to the pump. The fittings can include a pressure sensor for measuring pressure in the fittings. The aspiration catheter can be manipulated based on pressure and flow measurements. The fittings can include a docking manifold that can dock the connection suction of the suction extension to allow removal of the suction extension from hemostatic isolation and clearing of clots from the suction extension without further fittings such that the cleared suction extension can be efficiently reinserted for additional use.
Clot Retrieval Device for Ischemic Stroke Treatment
A clot removal device has a segment that has two main struts that serve as a frame for holding a plurality of secondary struts. Each of the two main struts has a proximal end that is connected at a proximal point of the segment and extends along a generally circumferential path, with each main strut terminating at a separate connecting point that is distal from the proximal point. The connecting points are connected to each other to form a generally tubular structure defining an inner lumen. The plurality of secondary struts forms a lattice of cells, with each cell surrounded by four secondary struts. Two generally straight distal struts are connected to the lattice of cells at a distal end of the segment, and are connected to each other to form a distal point.
