FIELD: medicine.
SUBSTANCE: invention refers to medicine, cardiosurgery. Vascular implant of polytetrafluoroethylene contains base 1 and valve flap 2 wired to base 1 with arc-shaped edge 3 of the locking element. Edge 4 of valve flap part 2 sewn to base 1 is made in the form of arc, chord of which is equal to chord of arc-shaped edge 3 of locking element, having thickness from 0.1 to 0.15 mm. Length of arc-shaped edge 3 of locking element is not less than 1/3 of arc 4 part length of valve flap 2, sewn to base 1. Base 1 has thickness from 0.6 to 0.65 mm and is made with width exceeding length of arc 4 of valve flap 2, sewn to base 1, at least 1.2 times.
EFFECT: device increases biocompatibility, reduces the frequency of repeated interventions for developing hemodynamically significant stenosis and pulmonary arterial insufficiency.
