#CMT# #/CMT# The annular prosthesis consists of a reinforcing wire in a continuous ring shaped in the form of a healthy aortic valve ring and having a suture zone extending all the way round. The suture zone is joined to the reinforcing wire, and the two are covered with a sleeve of polymer fibers. The reinforcing wire is supple to facilitate insertion into the aorta, being made from a stainless alloy such as Elgiloy(Cobalt chrome-nickel alloy - RTM). The prosthetic ring can be joined to an aortic segment prosthesis by suturing or thermal welding. #CMT#USE : #/CMT# Reinforcing an aortic valve to treat hemodynamic insufficiency. #CMT#ADVANTAGE : #/CMT# The prosthetic ring helps the surgeon to preserve the original aortic valve where possible. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of the aortic valve reinforcing ring. #CMT#POLYMERS : #/CMT# The reinforcing wire is covered with a sleeve of polyester fibers such as Dacron(RTM), and the suture zone consists of a Dacron(RTM) cord. |
