Abstract
Apparatus for intravenous therapy including hyperalimentation comprises a flexible closed-end catheter having a valve adjacent its proximal end. It is inserted through the skin of a patient and into a vein having a suitably large flow of blood therethrough. A removable internal stiffening member comprising a doubled, twisted flexible wire abuts the proximal closed catheter end. A distal female fluid flow fitting is fixed to the distal end of the stiffening member and is releasably attached to the distal catheter end. The distal end of the catheter has a male coupler allowing releasable connection of the fluid flow fitting of the internal stiffener to a source of intravenous solution which flows by gravity or pump means through the catheter and into the vein.
