Publication number: 20230233818Abstract: Devices, systems, and methods for performing thrombectomy procedures are disclosed herein. The devices can include an aspiration catheter which optionally has a beveled distal end. The aspiration catheter is advanced to a position adjacent a thrombus. A blocking element can be expanded near the distal end of the aspiration catheter to block fluid flow during the procedure. The devices can include a thrombus retrieval device supporting a braided assembly that grips and facilitates removal of the thrombus. The braided assembly is expandable to a range of expanded outer diameters by varying the level of tension in an activation wire attached thereto. An expander can be deployed beneath the braided assembly to exert an outward expansion force upon the braid, thereby increasing the grip between the braided assembly and the thrombus. The braided assembly contacts the thrombus and the retrieval device pulls it proximally toward the aspiration catheter.Type: ApplicationFiled: January 27, 2023Publication date: July 27, 2023Inventors: Ajit Nair, Ravish Sachar, Hung Ha

Publication number: 20230103258Abstract: The device disclosed herein is used to the remove a thrombus from the vasculature. It includes an aspiration catheter and a thrombus retrieval device that extends through the lumen of the aspiration catheter. An expandable braided assembly extends over a distal region of the retrieval device, and an activation wire extends through the lumen of the retrieval device to attach to and control the expansion of the braided assembly. Applying tension to the activation wire causes the braided assembly to expand to a diameter of the practitioner's choosing. For example, the practitioner may apply a first level of tension to the activation wire to deploy the braided assembly to a first diameter and then later change the diameter by applying a different level of tension. The expanded braided assembly contacts the thrombus and is pulled proximally toward the aspiration catheter to assist in thrombus removal.Type: ApplicationFiled: November 1, 2022Publication date: March 30, 2023Inventors: Ravish Sachar, Eugene Serina, Hung Ha, Dave Stern
