Abstract: Vaginal dilator assemblies, devices and kits. Assemblies can include a base, and an adapter. The base can have an inner portion and the adapter can have an outer portion that is complimentary to the inner portion of the base such that the adapter is non-rotatably fitted into the base. Vaginal dilator devices can include a base defining a recess aligned with the longitudinal axis of the base. The recess can have a plurality of step tapered sections. Vaginal dilator kits are also provided that include a plurality of vaginal dilators having different diameters. Each of the plurality of vaginal dilators is configured to be axially aligned and securely fitted into one of the step tapered sections of the recess of the base.

Abstract: Multistage thermal trigger devices disclosed herein may include a first stage and a second stage, wherein the first stage activates at a first temperature, and wherein the second stage activates at a second temperature. The first stage activates an arming assembly so that the second stage is armed. The second stage may then activate the output of the multistage thermal trigger device, via the arming assembly, when the second temperature is reached. An autoignition material (AIM) capsule is also disclosed herein. The AIM capsule may be deployed in connection with the disclosed multistage thermal trigger devices.
