Catheter devices and drainage systems for delivering therapeutic agents

A system for drainage of a wound and delivering a therapeutic agent at or near the wound of a patient, the system comprising:

• a catheter having a proximal end configured to receive the therapeutic agent and permit passage of bodily fluid, the proximal end configured to be coupled to a drainage tube and a therapeutic agent delivery device, the catheter having a distal end for insertion at or near the wound, the catheter having a body disposed between the proximal end and distal end of the catheter and configured to receive the therapeutic agent from the proximal end of the catheter, the body having a first set of holes configured to allow passage of the therapeutic agent from the proximal end to a site at or near the wound and a second set of holes configured to allow drainage of bodily fluid from the wound;
• a tube having a first end and a second end, the first end coupled to the proximal end of the catheter, the second end of the tube coupled to a collection container and delivery of the therapeutic agent to the catheter, the tube having a lumen configured to allow bodily fluids to pass through it to the collection container;
• and at least one port connected to the tube between the first and second end for administration of a therapeutic agent through the tube and into at least the proximal end of the catheter and through the first set of holes, wherein the first set of holes is disposed on at least a first, second and third region of the catheter and the second set of holes is disposed on at least a fourth, fifth and sixth region of the catheter in an alternating arrangement, and the first set of holes is a different diameter than the second set of holes, and the at least one port is disposed between the catheter and the collection container, wherein the at least one port comprises three ports with each port being coupled to a lumen forming a trilumen tubing, at least one of the ports having a cap configured to close one of the at least three ports, each lumen of the trilumen tubing being fluidly connected to a different drug channel of the tube such that therapeutic agents originating from each of the three ports are released from the first set of holes in different regions of the catheter.
