<p>An apparatus for performing correction of the pathology of pectus excavatum comprises at least one elongated bar and means of suture suitable to constrain the elongated bar in the vicinity of its first and second ends, in body tissues, either directly or by means of suitable stabilizers. The elongated bar, which must have certain mechanical characteristics of breaking load, yield strength and elasticity to withstand the stresses imposed by the chest, is made of a composite material made from a bioresorbable polymer matrix in which are disposed elongated metal. A method of removing the apparatus provides for performing an incision on one side of the chest, and then pull out one by one the elongated metal, taking advantage of the high flexibility of the foregoing.</p> |
