  • Patent number: 11484318
    Abstract: Disclosed herein are medical devices comprising a single-lobed, thin-walled, expandable body and a flexible, elongated delivery device for treating saccular vascular aneurysms and occluding segments of blood vessels and other biological conduits. The expandable bodies may include gold and other metals that can be compressed, positioned in the lumen of an aneurysm, or other biological conduit and expanded. The external surface of the expandable bodies can be configured to promote local thrombosis and to promote the growth of tissue into and around the surface in order to reduce migration of the expandable body and to occlude and seal the aneurysm or biological conduit. For the treatment of saccular aneurysms, the expandable body may be deployed in combination with one or more coiled wires that contact both the wall of the aneurysm and the expandable body and exert force on the expandable body to aid in sealing the aneurysm neck.

    Abstract: A catheter for prevention of stroke by diverting and filtering the blood flow to carotid and vertebral arteries is provided. The catheter includes at least one balloon with an outer mesh cover that expands upon the balloon inflation and collapses upon balloon deflation. Partial inflation of balloons provides for full mesh expansion in the target vessel with resulting capturing and retrieval of embolic particles. The inflation of the balloon in the aortic arch or head vessels expands the balloon associated filtering mesh leading to both filtering and deflection of embolic particles from the cerebral circulation, while balloon deflation triggers the mesh collapse and promotes its recapturing and retrieval while minimizing the risk of spillage of captured emboli.

  • Patent number: 11129715
    Abstract: Embodiments of the present disclosure provide an introducer device and method for introducing a delivery apparatus into a patient's vasculature. Disclosed methods can include positioning a sleeve of an introducer sheath in a blood vessel of a patient, the sleeve having a lattice layer with a lumen therethrough, inserting a distal end portion of the delivery apparatus and a prosthetic heart valve into the lumen, and advancing the distal end portion of the delivery apparatus through the lumen from the proximal end to the distal end. The method can then include expanding the lumen from a first diameter smaller to a second diameter at least equal to the diameter of the prosthetic heart valve to allow passage of the prosthetic heart valve through the lumen, and returning the lumen of the sleeve to a diameter smaller than the second diameter after advancing the prosthetic heart valve through the lumen.

  • Patent number: 11083573
    Abstract: A delivery system for an implantable stented device having a handle with a plurality of actuation members, each actuation member connected to one or more stent attachment elements, a sheath having a proximal end attached to the handle, and a plurality of tubes extending within the sheath. The stent attachment elements extend from distal ends of the tubes. A first actuation member is configured to move a first stent attachment element proximally toward the handle and a second actuation member is configured to move a second stent attachment element proximally toward the handle, sequentially releasing specific portions of the stented device by causing distal ends of the stent attachment elements to contact an exterior of the distal ends of the tubes, thereby disengaging the first and second stent attachment elements from the stented device.
