Beschreibung
Zusammenfassung:	A prosthesis for use in valvuloplasty. The prosthesis is formed as a linear reducer made of a material which is compatible with implantation and which in its direction of length is incompressible and inextensible but in the direction of its width is sufficiently flexible to assume a radius of curvature identical with that of the valvules; which can have needles introduced into it without tearing; which cannot be torn by the traction effect of the suture threads and of which the reduction ratio is governed by the distension of the deficient valvule. The prosthesis is intended for the surgical correction of certain mitral or tricuspid valvular disorders.
