Abstract: The disclosure relates to a plasma probe for generating a plasma for use in medical applications, in particular for treating tissue by coagulation. The probe has a probe body extending from a proximal probe end to a distal probe end and comprises at least one lumen configured for gas conduction. At the distal probe end, at least one electrode and at least one gas outlet opening are provided. The electrode comprises a flow guiding body that protrudes distally from the probe body at least in part and is provided with at least one guiding surface that is skewed with respect to the longitudinal axis (L). The guiding surface is configured such that a lateral flow component is superimposed on the discharging gas stream, thereby enabling targeted shaping and widening of the plasma zone. This improves, in particular, ignition stability and effectiveness in lateral applications.

Abstract: A plasma probe for coagulation and/or ablation of biological tissue of a patient is disclosed. It includes a hose that extends from a proximal hose end to a distal hose end and a probe head arranged on the distal hose end. The probe head comprises an electrode cage formed from multiple electrodes and extending from a proximal head end to a distal head end. The electrodes laterally project beyond the outer circumference of the hose at least in a section. The probe head additionally includes a central element and a centering element, wherein the central element defines a center axis of the probe head. The centering element is arranged at the distal head end. The electrodes of electrode cage are movable along the center axis relative to the central element.

Abstract: A surgical instrument for the treatment of a tissue surface, particularly for coagulation or ablation of the latter, an electrode consisting of carbon fibers or at least comprising carbon fibers for current conduction to the tissue surface. Anisotropy of the electrical conductance of the carbon fibers or the formed electrode results in a large area and uniform current distribution. Due to the configuration of the electrode surface by carbon fibers and particularly their high thermal conductivity, a sticking of the electrode to the tissue surface is effectively avoided.

Abstract: A method is provided for abruptly stopping a vibration motor providing tactile feedback (406) to the user of a portable communication device (100). The method comprises providing a drive waveform (401) including an attack signal (402), and a stop signal (411) out of phase with the attack signal (402), to one of the vibration motor (235) or the multi-function transducer (130) to quickly stop the vibration. The drive waveform may include an optional sustain signal (407) subsequent to the attack signal (402) and prior to the stop signal (411). A file stored in memory (212) is accessed to provide the drive waveform (401).

Abstract: An electronic device (100) comprises a housing (112), an input (118, 122) coupled mechanically to the housing for receiving data, an output (114, 118) coupled mechanically to the housing for presenting information to a user of the electronic device in at least one of an audio and visual mode, an electronic circuit (210) coupled mechanically to the housing for providing intelligent operations that receives the data from the input and provides the information to the output, and at least two electromechanical transducers (226), each providing a tactile alert to the user in response to the data, the tactile alerts occurring simultaneously or in succession.

Abstract: An electronic device (100) for performing intelligent operations includes a housing (112), a manually operable input (118, 122) for providing information to the electronic device, and a material (124) positioned between the manually operable input and the housing. An electromechanical transducer (218, 220) has a mechanical connection consisting of to the manually operable input and an electrical connection for receiving power, wherein substantially all of a mechanical output from the electromechanical transducer is provided to the manually operable input, the material preventing the mechanical output from being transmitted from the manually operable input to the housing.
