SUPPORT FOR CARDIAC VALVES OF ORGANIC TISSUES

Abstract

Abstract Translated from French L'INVENTION CONCERNE UN SUPPORT DE VALVULES CARDIAQUES EN TISSUS BIOLOGIQUES. SELON L'INVENTION, LE BORD PROXIMAL 1 DU SUPPORT POSSEDE UNE CONFIGURATION ONDULEE AVEC AUTANT DE CRETES QUE DE COMMISSURES SUR LA VALVULE AINSI SOUTENUE, LA PARTIE SAILLANTE MAXIMUM DE CES CRETES REPRESENTANT UN SIXIEME DE LA DISTANCE MAXIMUM ENTRE LES DEUX BORDS DU SUPPORT; LE BORD DISTAL 2 POSSEDE DES BRAS DE SOUTIENT 4 SEPARES PAR DES APPROFONDISSEMENTS DONT LA HAUTEUR EST DE L'ORDRE DE TROIS FOIS LA GRANDEUR DES CRETES DES ONDULATIONS DU BORD 1; UN CORDON CONTINU DE SUTURE 3 EST FORME DE FACON ONDULEE POUR CORRESPONDRE AUX PARTIES SAILLANTES ET AUX APPROFONDISSEMENTS DU BORD DISTAL, LES APPROFONDISSEMENTS DE LA PARTIE SAILLANTE DES CRETES DISTALES DU CORDON DE SUTURE ETANT D'UNE GRANDEUR NE DEPASSANT PAS LA MOITIE DE LA HAUTEUR TOTALE DU SUPPORT. L'INVENTION S'APPLIQUE NOTAMMENT A LA CHIRURGIE CARDIAQUE. THE INVENTION RELATES TO A CARDIAC VALVE SUPPORT IN BIOLOGICAL TISSUES. ACCORDING TO THE INVENTION, THE PROXIMAL EDGE 1 OF THE SUPPORT HAS A WAVY CONFIGURATION WITH AS MANY RIDGES ON THE VALVE THUS SUPPORTED, THE MAXIMUM PROJECTING PART OF THESE RIDGES REPRESENTING A SIXTH OF THE MAXIMUM DISTANCE BETWEEN THE TWO EDGES; DISTAL EDGE 2 HAS 4 SUPPORT ARMS SEPARATED BY DEPTHS OF WHICH THE HEIGHT IS OF THE ORDER OF THREE TIMES THE SIZE OF THE RIDGES OF EDGE 1; A CONTINUOUS CORD OF SUTURE 3 IS SHAPED IN A WAVY WAY TO CORRESPOND TO THE PROJECTING PARTS AND DEPTHS OF THE DISTAL EDGE, THE DEPTHS OF THE PROJECTING PART OF THE DISTAL RIDGES OF THE SUTURE CORD BEING NO MORE THAN THE HEIGHT EXCEEDING THE HEIGHT SUPPORT. THE INVENTION APPLIES IN PARTICULAR TO HEART SURGERY.
