APPARATUS AND METHODS FOR CONTAINING AND DELIVERING THERAPEUTIC AGENTS

摘要

The present embodiments provide apparatus and methods suitable for containing and delivering a therapeutic agent to a target site. The apparatus generally comprises at least one container (18) for holding a therapeutic agent, and a pressure source (70) for facilitating delivery of the therapeutic agent. In one embodiment, the pressure source may be placed in selective fluid communication with a proximal region of the container and fluid from the pressure source may flow through at least a portion of the container to urge the therapeutic agent through the container towards the target site. In an alternative embodiment, the pressure source may be selectively in fluid communication with either a first hollow tube (62) and the container so that therapeutic agent is urged into a catheter, or with a second hollow tube (63) and a catheter so that a fluid from the pressure source bypasses the container and enters the catheter.
