Organization conformity heart valve sewing ring

摘要

The artificial heart valve sewing ring which consists of the material which possesses the physical properties which resemble to peripheral organization conforms to peripheral organization and the emergency. This invention in and so on offers the sewing ring which possesses similar elasticity the elastic sewing ring, or soft organization. The illustrate material, silicone and the polyurethane, polyurethane copolymer, includes thermoplastic erasutoma of the rubber, and other blood conformity and organism conformity. When the said material, is more desirable from approximately 100psi to 5000psi and 10,000psi with modulus of elasticity, approximately 5000psi and 60,000psi between to 2000psi, from specifies from 200psi, from approximately 5000psi tensile strength between 50,000psi, and from approximately 100% between up to 3000%, it can possess the tensile growth rate between up to 1000% desirably from approximately 100. The said sewing ring, in order one somatotype or removal of the seam thread deviation from to become the help which is prevented, can be the fiber mat which possesses the fiber for strengthening which among those is embedded.
