VSU "RPMZ named Akad. V. Vakhidov street" together with NYSAFP Academy of Sciences of Uzbeki-stan developed a new aerial and hemostatic implant "Gabriel" which has passed preclinical testing. The article presents the results of clinical studies of the developed implant. Studies have shown that the use of a biological implant "Geprotsel" has reduced the need for additional single stitching lung tissue to ensure adequate Aero-and hemostasis from 38.2% to 11.4% and multiple strengthening seams from 29.4% to 5.7% (χ2=7,706; Df=2; P=0.021). The introduction of the domestic biological implant into lung surgery allowed to reduce the period to achieve Aero-and hemostasis from 32.8±2.5 to 12.5±1.2 minutes (P<0.001), the total duration of the operation from 135.6±6.1 to 107.2±4.7 minutes (P<0.001), as well as to reduce the duration of pleural drainage from 3.38±0.31 to 2.09±0.06 (P<0.001) and the entire period of hospitalization from 12.1±0.4 to 10.7±0.2 days (P<0.01)
