  • Patent number: 11147578
    Abstract: The present invention is directed to a method of endoscopically ablating/resecting/excluding (A/R/E) the mucosa of the gastric fundus and body. The method of the present invention is intended to cause cellular death to the X/A-like, ghrelin producing and other hormone cells. This is in contrast to present methods to provide only transient ischemia. The use of the method of the present invention results in a more permanent and robust method of reducing ghrelin and other hormone levels. In addition, a method according to the present invention can be used to induce scarring of the gastric fundus which will reduce gastric accommodation of excess food and result in early satiety.

  • Patent number: 11129671
    Abstract: A controller carries out a single outputting phase in which only first electric energy is supplied to an electrode, and transitions the single outputting phase to a simultaneous outputting phase in which the first electric energy and second electric energy are simultaneously output and treated target is denatured due to both of a high-frequency current and treatment energy generated in a functioning element. The controller sets a control pattern relating to the treatment energy in the simultaneous outputting phase, based on an impedance at a certain time point in the single outputting phase and/or a variation with time of the impedance in the single outputting phase.
