ABSTRACT:
A device for delivering medication into a human body, comprising a catheter having proximate and distal ends, and first and second lumina extending substantially the entire length of the catheter. A first opening in the catheter near its distal end drains fluid from a body when the catheter is inserted therein. There is a second opening in the catheter between the first opening and the distal end of the catheter. The second opening is fluidly connected with the second lumen. A diaphragm is located adjacent to the second opening for blocking off the second opening from the second lumen, and the diaphragm is burstable by a predetermined pressure for unblocking the second opening for fluidly connecting it with the second lumen. Thus, medications can be safely administered without the possibility of premature contact of the medication with the body. The catheter is particularly well suited to the administration of toxic substances such as BCG vaccine into the bladder of bladder cancer patients.
