Patent number: 10183168Abstract: Electrical stimulation of a target (e.g., nervous tissue) is performed, wherein balance phases are automatically determined, and at least one of the electrodes is indirectly monitored during therapy delivery. The stimulation system is further configured to generate correction currents when a voltage accumulated at associated double layer capacitances crosses pre-defined thresholds so as to reduce or cancel the accumulated voltages without therapy interruption. A finer automatic determination of balance phases permits minimizing the stimulus artifact for evoked response sensing. Closed-loop neurostimulation may be performed based on such evoked responses.Type: GrantFiled: March 7, 2017Date of Patent: January 22, 2019Assignee: BIOTRONIK SE & Co.

Patent number: 10092447Abstract: Ultra-short pulsed laser radiation is applied to a patient's eye to create a row of bubbles oriented perpendicular to the axis of vision. The row of bubbles leads to a region of the eye to be ablated. In a second step, a femtosecond laser beam guided through the row of bubbles converts it to a channel perpendicular to the axis of vision. In a third step, a femtosecond laser beam is guided through the channel to ablate a portion of the eye. Using a femtosecond laser with intensity in the range of 1011-1015 W/cm2 for the second and third steps facilitates multi-photon ablation that is practically devoid of eye tissue heating. Creating bubbles in the first step increases the speed of channel creation and channel diameter uniformity, thereby increasing the precision of the subsequent multi-photon ablation.Type: GrantFiled: April 26, 2016Date of Patent: October 9, 2018Inventors: Nicholas S.
