  • Patent number: 11065438
    Abstract: A system and method used to deliver a percutaneous ventricular assist device (pVAD) or other cardiac therapeutic device to a site within the heart, such as a site at the aortic valve. A flexible device is percutaneously introduced into a vasculature of a patient and positioned to run from a femoral vein, through the heart via a transseptal puncture, and to a femoral artery. The venous-side end of the flexible device is withdrawn out the venous vasculature superior to the heart, and a pVAD is secured to the flexible device. The pVAD is pushed in a distal direction while the arterial-side end of the flexible device is pulled in the proximal direction to advance the pVAD to the target site. A left ventricle redirector aids in orienting the pVAD and preventing migration of the flexible member towards delicate structures of the heart during advancement of the pVAD.

  • Patent number: 10828049
    Abstract: A medical device and method are disclosed which can cause a filter included in a cylinder to capture a capturing target by causing a fluid including a circulating flow to flow inside and around the cylinder introduced into a living body. The medical device has a filter, a cylinder, and an impeller. The filter captures a capturing target present inside a living body. The cylinder includes a lumen having the filter arranged therein, an aspiration section, which is open on the distal side of the lumen, and a discharge section which is open on a side surface on a proximal side of the lumen. The impeller is arranged on a proximal side of the filter in the lumen, and causes the lumen to aspirate the capturing target together with a fluid by causing the fluid to flow from the aspiration section toward the discharge section inside the living body.
