Apparatus and methods for containing and delivering therapeutic agents
First Claim
1. Apparatus suitable for facilitating delivery of a therapeutic agent, the apparatus comprising:
- a pressure source;
a container having proximal and distal ends with an inlet port at the proximal end for receiving a fluid from the pressure source;
a therapeutic agent disposed within the container;
a tube member having proximal and distal ends, the proximal end of the tube member positioned within the container; and
a flow obstruction member positioned within the container between the inlet port and the proximal end of the tube member, the flow obstruction member structured to direct fluid around the flow obstruction member and towards the proximal end of the tube member, the flow obstruction member and the tube member being spaced relative to each other to cause the fluid to flow around the obstruction member and draw the therapeutic agent into the tube member and direct the therapeutic agent distally therethrough.

Abstract
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 for holding a therapeutic agent, and a pressure source 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 and the container so that therapeutic agent is urged into a catheter, or with a second hollow tube and a catheter so that a fluid from the pressure source bypasses the container and enters the catheter.
