ABSTRACT:
A multi-function proximal end adapter (70, 86, 100) for a catheter (22) includes a hollow body (6) defining an axial lumen (8) extending between its proximal and distal ends (12, 10). An annular radially compressible seal (48) is positioned within the body along the axial lumen. A seal driver (58) is threadably mounted to the body and has a hollow extension (60) with a distal end adapted to axially compress the seal causing a radially inward deflection of the seal when the seal driver is threaded onto the body thereby providing a good seal against and securement for an object (such as a catheter or guide wire) passing through the axial lumen of the body. At least a portion of the proximal end of the axial lumen is defined by an internal tapered surface (36) sized to matingly and sealingly engage an external tapered surface (44) of a Luer lock connector (40) after the seal driver has been removed from the proximal end of the body.
