  • Patent number: 9339656
    Abstract: The present disclosure pertains to cardiac pacing methods and systems, and, more particularly, to cardiac resynchronization therapy (CRT). In particular, the present disclosure pertains to determining the efficacy of CRT through use of an effective capture test (ECT). One or more embodiments comprises sensing a signal in response to a ventricular pacing stimulus. Through signal processing, a number of features are parsed from the signal. Exemplary features parsed from the signal include a maximum amplitude, a maximum time associated with the maximum amplitude, a minimum amplitude, and a minimum time associated with the minimum amplitude. The data is evaluated through use of the ECT. By employing the ECT, efficacy of CRT is easily and automatically evaluated. In one or more other embodiments, the reason for ineffective capture is displayed to the user. Exemplary reasons for ineffective capture include pseudo-fusion pacing and lack of capture of the ventricle.

  • Patent number: 9278169
    Abstract: The present disclosure provides a system for oxygenating blood. The system may include an implantable blood pump that may draw a supply of blood from the circulatory system of a mammalian subject, such as a human being. The blood pump may provide the supply of blood to an adaptor, where the supply of blood may be supplied to either or both of a first branch or second branch. The first branch may lead to an external blood oxygenator. The oxygenator may oxygenate the blood, and the blood may be returned to the circulatory system of the mammalian subject. The second branch may bypass the oxygenator and may connect to the circulatory system of the mammalian subject. In this regard, while the blood is supplied to the second branch, the oxygenator may be disconnected and blood may be prevented from entering the first branch.
