Abstract
Abstract A multiple needle holder (10) and multiple channel subcutaneous infusion port (20) are disclosed. The multiple needle holder carries a plurality of needles (12) which are each in separate fluid communication with a lumen of a plurality of lumens in a multilumen catheter (40). The multiple infusion port includes a septum (28) 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 the infusion port each of said needles is in communication with a different one of said isolated chambers.
