  • Assessment of right ventricular function using contrast echocardiography
    Patent number: 9883850
    Abstract: Systems and methods are provided for determining a right ventricular transit time for a patient. An echodense contrast is injected into a patient. A first representative region, representing the right ventricle of the patient, is selected. A second representative region, representing the bifurcation of the main pulmonary artery, is selected. Respective first and second time series of intensity values for the first and second representative regions are generated via echocardiography. The right ventricular transit time is determined from the first and second time series of intensity values. The right ventricular transit time is displayed to a user.

  • Ablation catheter having temperature-controlled anchor and related methods
    Patent number: 9259261
    Abstract: One aspect of the present disclosure includes a catheter. The catheter includes a catheter body having a temperature-controlled anchor element thereon that is configured to attach the catheter body to tissue by forming a congealed adherence layer between the anchor element and the tissue. The catheter also includes an ablation element connected to the catheter body. The ablation element is axially spaced apart from the anchor element. The ablation element is configured to ablate tissue when the anchor element is attached to the tissue.
