  • METHODS AND SYSTEMS FOR THERMOEMBOLIZATION
    Publication number: 20170143348
    Abstract: Thermoembolization systems and techniques may provide simultaneous embolization and ablation of bodily tissue. In some embodiments, thermoembolization may be induced, for example, by arterially infusing a viscous liquid carrying an electrophilic material into the feeding vessel(s) of a tumor. The viscous liquid serves to occlude the arterial supply to the tumor while the electrophilic material concurrently undergoes an exothermic reaction when it comes into contact with water present in bodily tissues. In result, thermoembolization induces simultaneous hypoxic and thermal stresses to the tumor, thereby overwhelming tumor cells.

  • TREATMENT FOR PULMONARY DISORDERS
    Publication number: 20120215212
    Abstract: A thermochemical ablation system can be used to ablate a portion of a bodily structure, such as a human airway. In some examples, the thermochemical ablation system includes a first ablation reagent, a second ablation reagent, and an expandable balloon positioned adjacent the distal end of a catheter. The expandable balloon can be inserted into the bodily structure and the two ablation reagents combined to cause an exothermic reaction that generates heat. The heat may create a substantially uniform temperature distribution across the surface of the expandable balloon, providing substantially uniform ablation of tissue adjacent the balloon.

  • 4-substituted 5-polycyclylpyrimidine herbicides
    Patent number: 5780465
    Abstract: 4-Substituted 5-polycyclylpyrimidine compounds in which the 5-substituent is polycyclic and is attached to the pyrimidine moiety through an aliphatic carbon atom, such as 5-(2,2-dimethylindan-1-yl)-4-methylthiopyrimidine, were prepared and found to possess excellent herbicidal activity. The compounds are especially useful for the control of undesirable vegetation in paddy rice.
