Methods and systems are disclosed for treating diseased tissue by gentle heating. The method induces vasodilation on tissue disposed about an lumen having both healthy tissue and diseased tissue. The method includes coupling a probe surface to the luminal tissue at a target location and transmitting desired quantities of tissue remodeling energy from the coupled probe into each of a plurality of discrete remodeling zones in the luminal tissue so that the tissue remodeling energy heats the plurality of remodeling zones, the remodeling energy being configured to avoid muscular contraction and inhibit both acute and long-term occlusion of the lumen.

Inducing desirable temperature effects on body tissue

Medical devices and methods for making and using medical devices are disclosed. An example method may include a method for heating a body tissue region adjacent to a body lumen. The method may include positioning an energy delivery portion of a catheter within the lumen and engaging the body lumen with the energy delivery portion. Engaging the body lumen may complete a plurality of circuits. The method may also include determining a pulse characteristic in response to a thermal property of a first tissue type and applying controlled pulsed electrical energy with the pulse characteristic from the energy delivery portion through the plurality of circuits.

Selective accumulation of energy with or without knowledge of tissue topography

Methods and systems for heating a body tissue region adjacent a body lumen using selective accumulation of energy without knowledge of tissue topography. Methods include positioning an energy delivery portion of a catheter within the lumen adjacent the body tissue region, determining a pulse characteristic in response to a thermal property of a first tissue type and applying pulsed energy with the characteristic to treat a second tissue type within the region by drawing heat from the first tissue at a rate that inhibits thermal damage to the first tissue while building-up heat in the second tissue. Systems include a catheter body having an energy delivery portion processor configured to control a pulse characteristic of pulsed energy to therapeutically treat the second tissue by drawing heat from the first tissue at a rate that inhibits thermal damage to the first tissue while building-up heat in the second tissue.

A wearable ballistic impact protection system detects impacts to a body. The system includes multiple sensors for detecting vibration. The sensed vibrations are converted to electrical signals which are filtered. Electronic components are provided to determine whether the filtered signal have frequency and amplitude characteristics of impact that cause injury to a body. Preferably, the sensors are Piezo-electric film sensing elements. Information regarding the extent of the impact and injuries to the body may be transmitted to a remote location so that medics or other personnel may be informed to the extent of injuries to the body so that they may provide medical assistance.

Ballistic impact detection system

The invention generally pertains to reducing artifact noise signals present when non-invasive capacitive-type signal measurements are taken of static electric fields produced by an object of interest. According to a first preferred embodiment of the invention, a given static artifact signal is reduced by minimizing the potential difference between a ground point of sensor circuitry and the potential of the object. According to a second preferred embodiment of the invention, the change in signal due to motion of the sensor in the field produced by the object is minimized by reducing the impact of changes in coupling to the signal source.
