Patent ID: 8123670

Claim:
A vessel prosthesis comprising a tube having an internal surface that is provided with a pattern for swirling the blood flow in accordance with formulas: Q ⁡ ( t ) = ⌊ z + Z 0 ⁡ ( t ) ⌋ ⁢ r 2 φ = φ 0 + k ⁡ ( t ) ⁢ z k ⁡ ( t ) = Γ 0 ⁡ ( t ) 4 ⁢ π ⁢ ⁢ Q ⁡ ( t ) ⁢ C 0 ⁡ ( t ) wherein: φ 0 is the initial swirling angle in relation to the flow axis normal; φ, z and r are current values of the angular, longitudinal, and radial coordinates along the flow line; Q(t), Z 0 (t), k(t), Γ 0 (t), and C 0 (t) are parameters of a non-stationary swirled blood flow and geometry of the blood channel that depend on time because of non-stationary current and correspond to the individual normal indicators of the swirled blood flow measured by routine examination of a representative sample of patients showing no changes in the blood circulation system for a specific localization of the segment to be replaced with a prosthesis.
