Abstract
An infusion system for delivery of therapeutic fluids from a remote source into a patient'"'"'s body. The system has an infusion assembly, a rotating pivot joint member, a fluid connector assembly, and a sealing assembly retained within the infusion assembly between the housing of the infusion assembly and the rotating pivot joint member. The seal reduces leakage of fluids. The rotating joint may be pivoted to three distinct positions to allow for emplacement on the patient, delivery of the therapeutic fluid to the patient, and protected, sealed closure of the fluid channels to avoid patient fluid backflow.
