  • 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 The venous-side end of the flexible device is withdrawn out the venous vasculature superior to the heart, and a pVAD is secured to the flexible device.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: 11045634
    Abstract: A hemostasis valve body provides strong sealing around a medical device during insertion of the medical device into a blood vessel, low forces for tearing, and stability during insertion of the medical devices as well as during peel away. The valve body comprises a first surface, a second surface opposite the first surface, an edge, helical slits, and a pair of longitudinal cuts. The helical slits are positioned at a center of the valve body and traverse the first surface to the second surface. The helical slits provide a seal around the medical device. Each respective longitudinal cut extends from the first surface partially through the valve body to a depth short of the second surface for at least part of a length of the respective longitudinal cut. The longitudinal cuts facilitate a separation of the valve body into two parts during a peel away action.

  • Patent number: 11040202
    Abstract: Passive tissue biasing circuitry in an Implantable Pulse Generator (IPG) is disclosed to facilitate the sensing of neural responses by holding the voltage of the tissue to a common mode voltage (Vcm). The IPG's conductive case electrode, or any other electrode, is passively biased to Vcm using a capacitor, as opposed to actively driving the (case) electrode to a prescribed voltage using a voltage source. Once Vcm is established, voltages accompanying the production of stimulation pulses will be referenced to Vcm, which eases neural response sensing. An amplifier can be used to set a virtual reference voltage and to limit the amount of current that flows to the case during the production of Vcm. In other examples, circuitry can be used to monitor the virtual reference voltage as useful to enabling the sensing the neural responses, and as useful to setting a compliance voltage for the current generation circuitry.
