Medical devices for agent delivery and related methods of use

A system comprising:

• a medical device including a catheter;
• an agent delivery device positioned outside of the medical device and fluidly coupled to the catheter, the agent delivery device is configured to store and deliver an agent towards the medical device and into the catheter;
• and
• a fluid delivery device positioned outside of the medical device and fluidly coupled to the catheter, the fluid delivery device is configured to store and deliver a fluid towards the medical device and into the catheter;
• wherein, the medical device is configured so that, when a distal end of the catheter is positioned at a target site, the medical device can deliver the agent received from the agent delivery device and the fluid received from the fluid delivery device towards the target site via the catheter.

A system comprising:

• a medical device including a catheter;
• an agent delivery device fluidly coupled to the medical device via a first tube that is in fluid communication with the catheter, the agent delivery device includes an agent stored therein, wherein, upon actuation, the agent delivery device is configured to deliver the agent towards the medical device and into the catheter via the first tube;
• and
• a fluid delivery device fluidly coupled to the medical device via a second tube that is in fluid communication with the catheter, the fluid delivery device includes a fluid stored therein, wherein, upon actuation, the fluid delivery device is configured to deliver the fluid towards the medical device and into the catheter via the second tube;
• wherein the medical device is configured to receive and guide the agent and the fluid towards a target site via the catheter.

A method for delivering an agent and a fluid to a target tissue through a medical device, the method comprising:

• coupling an agent delivery device to the medical device, the agent delivery device storing the agent;
• coupling a fluid delivery device to the medical device, the fluid delivery device storing the fluid;
• positioning a catheter of the medical device at the target tissue;
• and
• actuating the agent delivery device to guide the agent through the catheter and the fluid delivery device to guide the fluid through the catheter, thereby delivering each of the agent and the fluid towards the target tissue via the medical device.
