Abstract A suprapubic catheter system comprising, a puncture member comprising an elongated needle, and having a distal end for placement in a patient, a proximal end and a lumen to receive the needle, a hollow connector attached to the proximal end of the catheter, connector is attached to the catheter proximal end, a hollow plug having a bore, a proximal annular flange and a device for releasably securing the plug to the proximal end of the connector, the internal diameter of the annular flange being of an increased diameter with respect to the diameter of the plug bore, and an elastic member having a pair of spaced annular flanges defining a groove to receive the plug flange, the pair of flanges including an inner flange and an outer flange, the internal diameter of the inner flange being approximately the same as the internal diameter of the plug bore, the internal portion of the elastic member inner flange thus forming a smooth continuation of the plug bore, and an end wall closing the bore and receiving the needle which may pass through the end wall, with the needle extending the distance between the elastic member and the distal end of the catheter.
A suprapubic catheter system comprising: a puncture member comprising an elongated needle; and a catheter assembly comprising an elongated catheter having a distal end for placement in a patient, a proximal end, and a lumen to receive the needle, a hollow connector attached to the proximal end of the catheter, means for attaching the connector to the catheter proximal end, a hollow plug having a bore, a proximal annular flange and means for releasably securing the plug to the proximal end of the connector, the internal diameter of the annular flange being of an increased diameter with respect to the diameter of the plug bore, and an elastic member having a pair of spaced annular flanges defining a groove to receive the plug flange, the pair of flanges including an inner flange and an outer flange, the internal diameter of the inner flange being approximately the same as the internal diameter of the plug bore, the internal portion of the elastic member inner flange thus forming a smooth continuation of the plug bore, and an end wall closing the bore and receiving the needle which may pass through the end wall, said needle extending the distance between the elastic member and the distal end of the catheter.
