[New textile vascular prostheses made of polymer composition materials]

Area of Science:

• Biomaterials Science
• Biomedical Engineering
• Materials Science

Background:

• The functional performance of blood vessel prostheses is critically dependent on the longitudinal elasticity of their walls.
• Designing prostheses with appropriate physico-chemical properties requires theoretical frameworks and specialized measurement techniques.
• Existing vascular prostheses often do not fully replicate the elastic characteristics of natural blood vessels.

Purpose of the Study:

• To develop and evaluate novel textile vascular prostheses capable of modeling biological tissue properties.
• To compare the elasticity and functional properties of new textile prostheses with natural blood vessels and traditional prostheses.

Main Methods:

• Development of theoretical foundations for designing the physico-chemical properties of prosthesis walls.
• Creation of specialized methods and measuring apparatuses for evaluating prosthesis properties.
• Comparative theoretical and experimental analysis of natural blood vessels, traditional prostheses, and new textile prostheses.

Main Results:

• New vascular textile prostheses were engineered using multiple polymer thread types with varying elasticity to model biological tissues.
• Comparative studies demonstrated that the new textile prostheses exhibit elasticity closest to the requirements for natural blood vessels.
• The novel prostheses showed promising functional properties.

Conclusions:

• The developed textile vascular prostheses demonstrate superior elasticity, closely matching natural blood vessels.
• These new prostheses represent a significant improvement over traditional designs, offering enhanced functional properties for vascular applications.
