Abstract
Methods and apparatus for short term and long term intravenous therapy including hyperalimentation are disclosed. The proximal end of a flexible catheter having a one way valve adjacent its proximal end is inserted through the skin of a patient and into a vein having a suitably large flow of blood therethrough. The distal end of the catheter has a threaded male coupler for connecting it to a flow reducing adaptor and thence to a source of intravenous solution. The solution flows by gravity through the catheter and into the vein. A passer which can be connected to the male coupler is provided for subcutaneously threading the catheter during long term catheter placement.
