Cannula connector and method of connecting medical tubes

摘要: A method for securing the connection of a medical tube to port fluid transfer instrument. The provides connections with superior resistance unexpected disconnection, and thus is particularly beneficial joining elastic tubes which are implanted within body conducting from one internal location another or between an external location. novel includes inserting rigid nipple on into lumen elastically deformable be joined port, placing initially loose fitting, nonelastically sleeve around nipple, deforming radially toward clamp nipple. extent deformation controlled prevent damaging tube. tool clamping also provided. invention further couplings include sleeves incorporated in connectors splicing together tubes. articles this preferably useful ventriculoperitoneal shunt procedures. connector has been discovered obviates need tie intradural ligature joint proximal catheter draining cerebrospinal ventricle brain. Medical made titanium containing metal provide radio-opacity without interfering magnetic resonance imaging.
