I-Central Venous Catheters (CVC) ayinyumba, isetyenziselwa enye kuphela i-polyurethane catheters eyenzelwe ukuququzelela unyango lwe-infusion kwindawo yokunyamekela. Zifumaneka kwiindidi ezahlukeneyo zokucwangciswa kwe-lumen, ubude, ubungakanani besiFrentshi kunye neGauge. Iintlobo ezininzi ze-lumen zibonelela nge-lumens ezinikezelweyo kunyango lokufakelwa, ukujonga uxinzelelo kunye nesampulu ye-venous. I-CVC ipakishwe kunye namacandelo kunye nezixhobo zokufakwa kunye ne-Seldinger technique. Zonke iimveliso zicocwa nge-ethylene oxide.
