INTRAPARIETAL AORTIC VALVE REINFORCEMENT DEVICE AND REINFORCED AORTIC VALVE

摘要

#CMT# #/CMT# The aortic valve intraparietal reinforcement (1), designed to be incorporated in a biological prosthesis (10) such as an aortic valve from an animal to maintain its shape after implanting, consists of a straight or spiral rod (2) inserted in the organic tissue of the prosthesis. The rod has a strut (3) fixed to one end and an attachment (4) at the other. The strut is in the form of a straight or curved bar, its curvature corresponding to the outer circumference of the biological prosthesis. The reinforcing rod is located, for example, in the outer tubular wall of the valve along the line of the wall's intersection with the valve's commissures. The can have a pointed tip that penetrates without damage to the organic tissue of the prosthesis; it can be made from a polymer or a supple metal such as titanium, and the rod and/or strut are/is covered with fabric. #CMT#USE : #/CMT# Prosthetic replacement heart valve for use in cardiac surgery. #CMT#ADVANTAGE : #/CMT# Combines advantages of stented and non-stented prostheses, especially by being retained in required shape without traditional stent and having maximum surface for primary function. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of the reinforced aortic valve prosthesis. 1 : Reinforcement 2 : Rod 3 : Strut 4 : Attachment 10 : Biological prosthesis 20 : Aorta 21 : Aortic root 22 : Rising aorta #CMT#POLYMERS : #/CMT# Preferred Material: The strut and/or attachment of the intraparietal reinforcing elements are covered with a Teflon(RTM; PTFE) fabric.
