The disclosure enables bi-directional mobile communication by researchers, clinicians or counselors with their patients and study participants. An exemplary application is ecological momentary assessment of psychological and physical status related to weight management. The system may be combined with objective information to trigger a communication and enhance responses assessed on food choices, dietary intake, physical activity, exertion, mood and companions.

One embodiment provides a method implemented by a powered inflation device to prepare a balloon catheter for use during a medical procedure. In this embodiment, the method includes drawing an amount of medical fluid from a fluid reservoir into the inflation device during a first motorized operation of the inflation device, removing an amount of air from the balloon catheter during a second motorized operation of the inflation device, and injecting the amount of medical fluid from the inflation device into the balloon catheter during a third motorized operation of the inflation device to inflate a balloon located at a distal end of the balloon catheter. The powered inflation device may be a stand-alone device in one embodiment. In one embodiment, the powered inflation device is coupled to an angiographic injector system. When it is coupled to an angiographic injector system, the balloon inflation device and the injector system may be controlled by a common control panel, or console, in one embodiment.

A wearable system of one or more body position or motion sensors can include a flexible sensing element to be coupled to or worn on a body. When straight, the flexible sensing element defines a longitudinal axis. It includes a lumen carrying a flowable substance, such as a liquid, gas, or gel. A measurable parameter of the flowable substance, such as pressure, volume, or flow, provides an indication of a longitudinal axial bending, twisting, or elongation, such as due to movement of at least one body part to which the sensing element is coupled. The lumen is coupled to a transducer by at least one conduit for the flowable substance. The transducer converts the measurable parameter of the flowable substance into a transducer output signal indicative of the longitudinal axial bending, twisting, or elongation of the sensing element, from which body part position or movement information can be derived.

A medical stopcock is provided that is constructed and arranged to withstand high pressures and gamma irradiation. The stopcock generally includes a housing and a valve member. The valve member is trapped within the housing so that, when subjected to relatively high pressures, the valve member is unlikely to become separated from the housing. A handle member is attached to the valve member and allows the valve member to be rotated from open to closed positions. In some preferred embodiments, the handle member locks the valve member within the housing, when attached. All of the components are constructed of gamma-stable materials so that the stopcock may be sterilized, in its package, using gamma irradiation.
