DEVICE OF A DIVISIBLE PROSTHETIC MECHANICAL HEART VALVE

摘要

Device of a divisible prosthetic mechanical heart valve, consisting of two structural elements: A. An external stationary ring (1) consisting in turn of two subsequent elements (1 i, 1 ii), and B. An internal moving part (2), which are connected with a connecting wire (3). The external part consists of an annular metallic ring with female groove and an opening (1 i), and of a second ring made out of cloth (1 ii). The internal part (2) consists of a metallic ring and of moving semicircular wings, which can be clamped after implantation of the external ring (1). The advantage of this device is that during valve implantation, initially the external ring is placed and then the internal. Also, in case of post operational implication, total valve removal is not needed, but only the internal part can be removed and then its replacement or implantation can follow.
