Abstract

A delivery system for delivering a therapeutic agent to a patient includes a catheter, a stop feature, a container and a bar. The catheter has a proximal end and a distal end and includes a body defining a lumen that extends to the distal end of the catheter. The stop feature is in proximity to the distal end of the catheter. The container is configured to house the therapeutic agent and is insertable and slidably disposable in the lumen of the catheter. The container is also configured to engage the stop feature of the catheter. The bar is slidably disposable in the lumen of the catheter. Sliding of the bar distally in the lumen forces the therapeutic agent out of the container and out of the lumen when the container is engaged with the stop feature. The stop feature is configured to inhibit the container from exiting the lumen.
