  • Expansible fixing plug
    Patent number: 11767869
    Abstract: An expansible fixing plug, having a sleeve-like portion, an expander body, and an expansion part which has expansion elements which, in a non-expanded state, are integrally joined to the sleeve-like portion and to the expander body. In addition, the expansion part has connecting elements which integrally join the sleeve-like portion and the expander body in the non-expanded state and also in the expanded state. The connecting elements are interlockingly connected to the expander body.

  • Intralumenal microwave device
    Publication number: 20070055224
    Abstract: A microwave device that can be used to effectively treat esophageal pathologies comprises a coaxial, triaxial or quadraxial microwave antenna housed in an esophageal dilator or balloon. The device can be introduced into the esophagus alongside or through an endoscope, and will deliver microwave energy to tissue. This energy heats the affected tissue, which subsequently undergoes necrosis thereby eliminating the potential of the tissue to undergo malignant transformation. The dilator or balloon is used to keep the antenna in the center of the lumen allowing for symmetrical heating of the esophagus. The depth of penetration of the coagulation effect can be varied depending on the amount of power that is applied, the location of the antenna relative to the tissue, and the duration of the power application.
