1. A prosthesis for use in valvuloplasty comprising a linear reducer made of a material which is compatible with the implantation, which in the direction of its 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 suture threads, and of which the reduction ratio is governed by the distension of the deficient valvule.
