Patent number: 11839393Abstract: A method is disclosed for removing a vascular occlusion, such as a clot, from a blood vessel. A tubular sheath is inserted into the vessel and a self-expanding Nitinol mesh filter is deployed from a distal end of the tubular sheath at a location proximal to a clot. An inner catheter is advanced through the tubular sheath and through the mesh filter for contacting the clot. An expandable agitation element is provided along a distal end portion of the inner catheter for cutting or chopping the clot, thereby facilitating removal of the clot and improving blood flow through the vessel. Resulting clot particles are captured by the mesh filter. Negative pressure may be applied along a proximal end portion of the sheath for aspirating remaining particles. Certain embodiments of the method are well-suited for treating deep vein thrombosis and do not require the use of thrombolytic drugs.Type: GrantFiled: February 11, 2022Date of Patent: December 12, 2023Assignee: Inari Medical, Inc.Inventor: David L. Hauser

Patent number: 11839373Abstract: A magnet-assisted suture grasper for grasping a magnetic suture is provided. The magnet-assisted suture grasper includes a suture retrieval needle, a retriever body, a grasper wire, a grasper arm, and a grasper magnet. Translation of the retriever body within a needle lumen of the suture retrieval needle in a first direction causes the grasper arm to move from a first position to a second position, thereby exposing the grasper magnet from the needle lumen and allowing contact between the grasper magnet and a magnetic suture attracted thereto. Translation of the retriever body within the needle lumen in a second direction opposite the first direction causes the grasper arm to move from the second position to the first position, thereby sequestering the grasper magnet and grasping the magnetic suture within the needle lumen.Type: GrantFiled: May 17, 2022Date of Patent: December 12, 2023Assignee: APPLIED MEDICAL TECHNOLOGY, INC.Inventors: Grant Wesley Phillips, Steven Alfred Soeder, George J.

Patent number: 11819203Abstract: A system includes a first tube, a sharp coil at a distal end of the first tube, a second tube displaceable within the first tube, and a sharp housing at a distal of the second tube for storing fasteners. The housing can be positioned at a first tissue, and the coil rotated to advance the coil into engagement with the first tissue. The first tube is retracted to retract the first tissue, and then a first fastener is deployed at the first tissue location. Then, without removing the system from the patient, the distal end of the system is moved adjacent a second tissue location, and the process is repeated for a second fastener at the second tissue location. A suture extends between the first and second fasteners, and tension is applied to the suture to draw the first and second tissues toward each other to reconfigure the tissue.Type: GrantFiled: October 1, 2019Date of Patent: November 21, 2023Assignee: Apollo Endosurgery US, Inc.Inventors: Vladimir Mitelberg, Charles Dean
