Claim:
1. A downhole stimulation device, comprising: a rigid housing having a first end, a second end, and a longitudinal axis extending between the first end and the second end; an energetic material disposed within the housing and completely enclosed by the stimulation device; and an initiator positioned exterior to the housing and removably coupled to one of the first end and the second end of the housing, the initiator comprising a shaped charge for igniting the energetic material within the housing, wherein the shaped charge is configured to produce a projectile to penetrate the energetic material to ignite the energetic material along a majority of the housing from the first end to the second end of the housing, and wherein a majority of the energetic material is positioned in the housing radially outward from the initiator in order to produce a radial burn in the energetic material extending outward toward the housing after the energetic material has been ignited by the projectile, wherein the housing is adapted to deform under internal pressure in the housing caused by gases produced by combustion of the energetic material to form at least one aperture in the housing in order to expel the gases produced by the combustion of the energetic material.
