Patent number: 11925369Abstract: 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: March 12, 2024Assignee: Inari Medical, Inc.Inventor: David L.

Patent number: 11839545Abstract: A method of treating a defective heart valve includes inserting a delivery catheter through a small incision in a patient's groin, wherein the delivery catheter has a prosthetic device positioned along a distal end. The prosthetic device includes an insert member and an anchoring member. The insert member self-expands to plug gaps between leaflets of the heart valve. The anchoring member is preferably a stent connected to the insert member by at least one elongate member. The stent is deployed within an adjacent blood vessel for anchoring the insert member. After deployment of the prosthetic device, the leaflets of the heart valve form a tight seal against the insert member for preventing regurgitation when the leaflets are closed and wherein blood passes through the insert member when the leaflets are open.Type: GrantFiled: October 7, 2021Date of Patent: December 12, 2023Assignee: EDWARDS LIFESCIENCES CORPORATIONInventors: David L. Hauser, Jan Otto Solem, David Alon

Patent number: 11166817Abstract: Disclosed herein are devices for improving coaption of the mitral valve leaflets to reduce or eliminate mitral valve regurgitation. The devices may be used to perform mitral valve annuloplasty, or to serve as a docking station for a transcatheter prosthetic heart valve. The various embodiments of devices are configured for percutaneous and, in some cases, transvascular delivery. Delivery systems useful for routing the devices to the mitral valve are also disclosed, including catheters, balloons and/or mechanical expansion systems. The devices themselves include at least one tissue penetrating member. Methods of delivery include partially embedding the devices in the mitral valve annulus via at least one tissue penetrating member. Tissue penetrating members may be embedded into the tissue in a simultaneous or a nearly simultaneous fashion. Upon embedding, the devices employ various expansion and/or contraction features to adjust the mitral valve diameter.Type: GrantFiled: March 19, 2019Date of Patent: November 9, 2021Assignee: Edwards Lifesciences CorporationInventors: David M.
