  • Patent number: 11090174
    Abstract: A temporary expandable tissue support device includes a plurality of helical filaments superimposed on top of one another to form a tubular body. A first end of the tubular body is coupled to an inner shaft, and a second end of the tubular body is coupled to an outer shaft slidably disposed over the inner shaft. Actuation of the inner and outer shafts in a first direction compresses the plurality of filaments thereby radially expanding the tubular body into an expanded configuration adapted to engage and support tissue at a treatment site without obstructing a fluid from flowing past the tubular body. Actuation of the shafts in a second direction opposite the first direction tensions the plurality of filaments thereby radially collapsing the tubular body into a collapsed configuration that is adapted to be delivered to or removed from the treatment site.

  • Patent number: 10792471
    Abstract: A delivery sheath includes an elastic outer tubular layer and an inner tubular layer having a thick wall portion integrally connected to a thin wall portion. The inner tubular layer can have a compressed or folded condition wherein the thin wall portion folds onto an outer surface of the thick wall portion under urging of the elastic outer tubular layer. When an implant passes therethrough, the outer tubular layer stretches and the inner tubular layer unfolds into an expanded lumen diameter. Once the implant passes, the outer tubular layer again urges the inner tubular layer into the compressed condition with the sheath reassuming its smaller profile. The sheath may also include selectively placed longitudinal rods that mediate friction between the inner and outer tubular layers to facilitate easy expansion and collapse, thereby reducing the push force needed to advance the implant through the sheath's lumen.

  • Patent number: 10751206
    Abstract: A method for delivering catheters, and stents composed of soft, compliant polymers through anatomical passages. These devices have a bulbous or enlarged anchorage end with a diameter greater than the rest of the catheter. To facilitate implant and delivery a pusher catheter or sheath with an internal lumen larger than the outer diameter of the catheter but smaller than the outer diameter of the bulbous or enlarged anchorage end is provided. The distal end of pusher catheter or the sheath physically engages the proximal end of the bulbous or enlarged anchorage end and applies an axial force to coaxially advance the catheter over a guidewire through anatomical passages. This method allows a physician to move the catheter to an anatomical site without the device exhibiting buckling due to axial force applied. Similarly, this delivery method will allow more force to be applied to the distal end of the catheter diminishing the likelihood of buckling.

  • Patent number: 10537308
    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 stays expanded after the balloon is deflated. The inflation of the balloon in the aortic arch or head vessels provides the deflection of embolic particles from the cerebral circulation and expands the outer mesh that provides for filtering and deflection of cerebral emboli after the balloon is deflated. An associated method of prevention of cerebral emboli and embolic stroke is provided.

  • Patent number: 10500377
    Abstract: A delivery sheath includes an outer tubular layer and an initially folded inner tubular layer. When an implant passes therethrough, the outer tubular layer expands and the inner tubular layer unfolds into an expanded lumen diameter. The sheath may also include selectively placed longitudinal support rods that mediate friction between the inner and outer tubular layers to facilitate easy expansion, thereby reducing the push force needed to advance the implant through the sheath's lumen.
