CARCASSLESS PROSTHESIS OF AORTA ROOT Russian patent published in 2007 - IPC A61F2/24 

FIELD: medical engineering.

SUBSTANCE: device has tubular body with bulgings formed by rigid connection of three units. Vascular prostheses manufactured from synthetic material are attached to the upper and lower end faces. Each unit has external and internal member. The external member is 0.6-1.0 mm thick and is manufactured from synthetic material. The external member shape and size matches aorta root shape and size with two halves of subcommissural space and one-third of fibrous base of the aorta root. The internal member is sutured to the internal wall of external member along line corresponding to aorta root flaps attachment line to fibrous ring line and is manufactured from 0.1-0.3 mm thick synthetic material. The vascular prosthesis sutured to the upper end face has diameter of 26 mm and length of 25 mm. The vascular prosthesis sutured to the lower end face has diameter of 22-26 mm and width of 5 mm.

EFFECT: prolonged service life.
