Propellant pillow
First Claim
1. An implantable pump system comprising:
- a propellant pillow including;
a propellant bag for containing a propellant;
a self-sealing septum attached to the propellant bag; and
a rigid member associated with the propellant bag, wherein the rigid member prevents piercing of the propellant bag by an injection device inserted through the septum; and
a fluid or medicament chamber associated with the propellant pillow, the fluid chamber being in communication with a conduit for delivering the fluid or medicament to a patient.

Abstract
A propellant pillow for use in an implantable pump is described herein. The propellant pillow generally includes a propellant bag having a septum attached thereto. In one embodiment, the pillow may further include a rigid member associated with the propellant bag to prevent piercing of the bag by an injection device inserted through the septum during a filling process. In another embodiment, the propellant pillow includes a propellant bag having a surrounding layer of resealable material encompassing the bag. The surrounding layer also serves to prevent piercing of the bag during filling of the pillow with a propellant. Methods of filling such propellant pillows with propellant as well as utilizing such pillows in connection with implantable pumps are also described herein.
