Abstract: An improved medical device reduces the loss of longitudinal length during expansion of a stent-graft from a compressed state to an expanded state. For example, the stent-graft is placed over a cover that provides resistance to expansion of the balloon during inflation, which reduces longitudinal compressing forces exerted on the stent-graft.

Abstract: Synthetic training interface devices, methods, and systems. A synthetic training device includes a processor, a communications interface in communication with the processor, a measurement device in communication with the processor, and an input device disposed on a live training device and configured to receive input from a user. Calibration information is captured. The calibration information includes orientation, position, inertial, and/or geometric information regarding the synthetic training interface device, a live training device coupled to the synthetic training interface device, the user, and/or a synthetic training environment. The calibration information is captured via a measurement device and/or user input.

Abstract: A system and method for enabling two-way communication between a residents of a secure facility (inmate, patient, suspect, etc.) and outside parties shares a limited number of telephone numbers (ANIs) by creating distinct communication channels using other data in addition to the shared ANIs.
