Abstract
Abstract A multiple needle holder and multiple channel subcutaneous infusion port are disclosed. The multiple needle holder carries a plurality of needles which are each in separate fluid communication with a lumen of a plurality of lumens in a multilumen catheter. The multiple infusion port includes a septum which overlies a plurality of isolated chambers. Each chamber is accessed by a tube which connects to a different lumen of a subcutaneous multilumen catheter. When the needles of said needle holder are inserted through the septum of said infusion port each of said needles is in communication with a different one of said isolated chambers.
