20130144326 | CLOT CAPTURE SYSTEMS AND ASSOCIATED METHODS - A clot capture system for disengaging a clot from a vessel wall and removing the clot from the vessel, comprises a clot capture device for placement on a distal side of a clot. The clot capture device has a retracted delivery configuration and an expanded deployed configuration. The clot removal device has a proximal support frame, and a distal fibre net. The support frame has a retracted delivery configuration and an expanded deployed configuration. The proximal support frame in the expanded configuration defines a proximal inlet mouth for engaging a clot and a net for confining the clot. An elongate member facilitates capture and/or withdrawal of a clot from a vessel. | 06-06-2013 |
20130184739 | CLOT ENGAGEMENT AND REMOVAL SYSTEMS - A device for the removal of clot obstructing the flow of blood through an arterial vessel comprises an elongate member, a clot engaging element and a capture basket. The elongate member extends in use from a point adjacent a target treatment site interior of the patient to a point exterior of the patient. The capture basket comprises a frame and a net, and has an expanded and a collapsed configuration. The clot engaging element comprises a plurality of struts having an expanded and a collapsed configuration. The plurality of struts form a first section and a second section, the first section tapering outward and distally from the elongate member and connected to the second section. The second section comprises a plurality of cells defined by a plurality of struts and arranged around at least a portion of the circumference of an axis substantially parallel to that of the elongate member. The clot engaging element and the capture basket are restrained in the collapsed configuration for delivery to the target site. The clot engaging element is located adjacent the distal end of the elongate member and proximal of the capture basket. | 07-18-2013 |

20140277079 | CLOT RETRIEVAL DEVICES - A self-expandable mechanical clot retrieval device is designed variously to dislodge, engage and retract blood clot from extremely small and tortuous vasculature. The retrieval device comprises an elongate member and a plurality of ring elements. The ring elements may comprise a plurality of struts and crowns interconnected by a tether formed at a distal end of the elongate member or may be a separate component attached thereto. At least one tether may connect each ring element to the elongate member to restrain the ring element in a collapsed configuration during delivery of the retrieval device through an intravascular microcatheter. The tether connecting the ring element to the elongate member disengages when the retrieval device is positioned at the occluded site and the microcatheter is retracted to allow the self-expandable ring elements to reach an expanded configuration. | 09-18-2014 |
20140371769 | CLOT REMOVAL DEVICE - A system may comprise a clot engagement element having a collapsed delivery configuration and an expanded configuration for engaging with a clot and for dislodging the clot from a first vessel segment. An elongate member may be configured to apply a pull force to the clot engaging element to dislodge the clot from the first vessel segment. A clot removal catheter may include a lumen at its distal end sized to receive the clot and configured to maintain a stable position in a second blood vessel segment proximal of and larger in diameter than the first blood vessel segment. A distal end of the elongate member may be configured to protect a third blood vessel segment between the first and second blood vessel segments from tractive forces transmitted by the elongate member during clot dislodgement from the first vessel segment. | 12-18-2014 |
20140371779 | CLOT RETRIEVAL DEVICE FOR REMOVING OCCLUSIVE CLOT FROM A BLOOD VESSEL - A clot retrieval device may include an elongate member and an expandable clot engaging element configured to extend across the clot in its expanded state. The expandable clot engaging element may include a first monolithic structure and a second monolithic structure. The first monolithic structure may encircle the second monolithic structure over at least a portion of its length. The second monolithic structure may include a proximal section, an intermediate section, and a distal section. The distal section may include an expansion. | 12-18-2014 |
20140371780 | DEVICES AND METHODS FOR REMOVAL OF ACUTE BLOCKAGES FROM BLOOD VESSELS - A clot retrieval device may include an elongate shaft and an expandable section. The expandable section may include a framework of interconnected strut elements. The connection region between adjacent strut elements may include crown elements. Additionally, the framework may be formed from a substrate material and at least a portion of a plurality of said strut elements may be coated with a coating material. Further, at least a portion of a plurality of said crown elements may not be coated with said coating material. | 12-18-2014 |
