METHOD AND DEVICE FOR ENDOSCOPIC ABLATION OF GASTRIC MUCOSA NEOPLASMS Russian patent published in 2013 - IPC A61B17/94 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medicine and can be applied for endoscopic ablation of gastric mucosa. Step-by-step hydraulic dissection with preparation under pressure with automatic dosed supply of preparation is carried out. Device for ablation of neoplasms of gastric mucosa contains endoscope, provided with catheter, with located inside it electricity-conducting string with tip on distal end, and connected with coagulation device; prom proximal side it contains catheter, connected with automatic system, regulated in volume and pressure of preparation supply to place of neoplasm ablation, system includes command apparatus ruler, connected with drive cylinder and having upper mobile rest, fixed with screw, including tap cam, with fixer for supply of air pressure in drive cylinder, whose movement lifts regulated load, and preparation from reservoir with preparation is supplied into syringe through reverse valve; tap with fixer for stop of air pressure supply into drive cylinder and output of air from it, is switched by means of lower screw-fixed regulated rest, with cam; regulated load carries out supply of preparation with syringe through reverse valve via catheter to the place of neoplasm ablation.
