Abstract: A corneal lenticule extraction procedure provides convenient re-treatment options when treatment interruptions occur. The procedure is executed by an ophthalmic laser system according to a programmed treatment plan, which defines an entry cut, an optional ring cut, a bottom lenticule incision having an optical zone, and a flat top bed incision. If an interruption occurs during the entry cut, the treatment plan is re-aligned with the partially formed entry cut and continued, or with a new entry cut placed at a different angular position. If an interruption occurs during the ring cut, the treatment plan is revised to define a larger ring cut concentric with the partially formed ring cut. If an interruption occurs during the bottom or top incision, the depth of the partially formed bottom or top incision is measured, and the treatment plan is revised to form a deeper bottom incision or a shallower top incision, respectively.

Abstract: Methods for surfactant enhanced laser-induced vapor bubbles for use in laser lithotripsy. Urinary tract stone disease is a common and costly disease that effects approximately 10% of the United States population. A preferred minimally invasive method for treatment of urinary tract stones is laser lithotripsy, which involves insertion of a flexible ureteroscope through the urinary tract to the stone's location, and then transmission of infrared (IR) laser energy through a flexible optical fiber, which is in turn placed through the single working channel of the ureteroscope. The IR laser energy is used for ablation of the urinary tract stone which is then removed. In order to have a more efficient ablation, the ureteroscope is fed with a surfactant composition which is flowed into the ureter and/or kidney of the subject. The laser causes larger bubbles to form in the surfactant composition, making a robust and longer lasting bubble.

Abstract: A wearable physiological monitoring device is configured to determine a wearer's sleep intention. In particular, the device evaluates activity that might be objectively associated with awaking from sleep in order to distinguish between a wearer's intention to end sleep and transitory stirring or other intermittent activity occurring in the context of a longer sleep interval. By evaluating sleep intention more accurately in this manner, the device can advantageously request sleep analysis from a remote server in those instances where a user intends to end a period of sleep (so that this data can be available to the user more quickly), while avoiding unnecessary or redundant server-side processing of sleep data in those instances where a user intends to continue sleeping.
