Abstract
A delivery system having a telescoping spring is used to drive a plunger. The telescoping spring includes a nested inner spring that uses the unused volume on the inside of an outer spring. The telescoping spring has a staged release of each spring. The inner spring is connected to a non-anchored end of the outer spring, and rides within a container located within an inner dimension of the outer spring. The spring constant K of each spring can be the same or different. The delivery system can be fully mechanical or implemented as a smart delivery system under electronic control.
