A bi-stable snap action ribbon spring incorporated into self-latching, spring-loaded mechanisms. The dual mode stability of the spring eliminates the need for complex latching mechanisms thereby simplifying the device manufacture and device reliability. The spring is stable in either a linear or coiled state enabling the simplified design of rolling, hinging and feeding mechanisms. A plan or map rolling and presentation device incorporates a bi-stable snap action ribbon spring along with optional spring end caps and stiffening elements.

A laser sustained plasma light source includes a plasma bulb containing a working gas flow driven by an electric current sustained within the plasma bulb. Charged particles are introduced into the working gas of the plasma bulb. An arrangement of electrodes maintained at different voltage levels drive the charged particles through the working gas. The movement of the charged particles within the working gas causes the working gas to flow in the direction of movement of the charged particles by entrainment. The resulting working gas flow increases convection around the plasma and increases laser to plasma interaction. The working gas flow within the plasma bulb can be stabilized and controlled by control of the voltages present on the each of the electrodes. A more stable flow of working gas through the plasma contributes to a more stable plasma shape and position within the plasma bulb.

The invention relates to devices and methods for reforming tissue surrounding the airway of a subject suffering from obstructive sleep apnea so as to open the airway and alleviate the occurrence of apneic events. Devices comprise a combination of resiliently deformable material and bioerodible material. The deformable portion of the device has a preferred shape that corresponds to the desired final shape of the device once placed in an airway. In making a transplant-ready device, however, the deformable portion is placed into a deformed shape and constrained in that shape by the bioerodible material. After implantation, the device gradually assumes the preferred shape as the constraining bioerodible material erodes. As the device gradually reforms toward the preferred shape, it reforms the tissue into the therapeutically desirable configuration. The gradual nature of the shape change generally stabilizes the device in the tissue, and supports tissue reforming into a stable configuration.
