POLYTETRAFLUOROEHTYLENE IMPLANT AND METHODS OF THORACOSCOPIC PLASTY OF DIAPHRAGM IN NEWBORNS OR CHILDREN OF EARLY AGE WITH APPLICATION OF IMPLANT Russian patent published in 2012 - IPC A61F2/02 

FIELD: medicine.

SUBSTANCE: group of inventions relates to field of medicine, namely to thoracoscopic surgery, and can be applied in plastic operations on diaphragm in newborns or children of early age. For this purpose applied is implant from porous stretched polytetrafluoroethylene (PTFE), which includes not fewer than 10 layers of more porous PTFE and not fewer than 1 layer of less porous PTFE with total implant porosity being not less than 80% and thickness 1-1.5 mm. Less porous layer has smooth surface and volume share of space of cavities 20-40%, specific surface of space of cavities 0.10-0.35 mcm³/mcm², average distance between cavities in volume 1-10 mcm, average volume chord 1-5 mcm. More porous layer has rough surface, volume share of space of cavities 80-95%, specific surface of space of cavities 0.75-0.95 mcm³/mcm², average distance between cavities in volume 30-45 mcm, average volume chord 15-25 mcm. Methods of diaphragm plasty with aplasia of its cupula and with congenital diaphragmatic false hernias include application of patch from said implant. Patch is introduced through thoracoscopic hole in folded form. Patch is placed in such a way that its smooth surface faces abdominal cavity, and rough surface faces pleural cavity.

EFFECT: application of said group of inventions makes it possible to carry out adequate correction of diaphragm cupula in newborns, reduce mortality and development of complications.
