  • Patent number: 10357448
    Abstract: We disclose a composition comprising an echogenic liposome (ELIP) having an exterior surface, an interior surface, and at least one bilayer comprising at least one lipid selected from the group consisting of saturated phospholipids, unsaturated phospholipids, mixed phospholipids, and cholesterol, and a thrombolytic compound trapped by the ELIP. We also disclose a method of treating a medical condition in a patient characterized by a thrombus in the patient's vasculature, comprising administering to the patient the composition in an amount effective to reduce the size of the thrombus.

  • Publication number: 20190095589
    Abstract: Embodiments disclosed herein provide a system and method for selecting, modeling and analyzing various surgical treatments of mitral valves. In some embodiments, a mitral valve is simulated based on imaging and Doppler ultrasound data acquired from the mitral valve. The function of the mitral valve is simulated, and then a plurality of surgical techniques is simulated for the mitral valve to help determine the best mitral valve treatment.

  • Patent number: 5957950
    Abstract: A system and method for performing balloon angioplasty treatment on a patient. The system includes a catheter for insertion into an artery of the patient, a balloon coupled to the catheter with the balloon expandable by fluid passed through the catheter in order to apply pressure to plaque lesions deposited on vascular tissue of the artery. The balloon includes a PVDF piezoelectric transducer for sensing acoustic emission signals generated by deformation of the plaque lesions and the vascular tissue. The acoustic emission signals can be analyzed by frequency analysis, time domain analysis and wavelet analysis followed by neural net correlation evaluation.
