Abstract: Methods and apparatuses for determining operational parameters of a blood pump comprising a rotor which transports the blood are provided. The change in the behaviour of at least one first and one second operational parameter, independently from each other, of the pump, is determined. A determination of the flow through the pump and/or the difference in pressure across the pump and/or the viscosity of the blood takes into account the determined change in behaviour of the at least two operational parameters. A modelling for a dynamic model of the known quantities may be carried out and an estimation method using a Kalman filter may be used.

Abstract: This external stimulus application system is structured so as to comprise: an external stimulus unit that applies an external stimulus to a target area of a user's body; a detection unit that detects changes in a detected area of the user's body during an action of the user; a control unit that causes the external stimulus unit to produce a stimulus if a detected value detected by the detection unit satisfies a prescribed condition; and a storage unit that stores the detected value.

Abstract: Neurostimulation of a mixed nerve comprising a plurality of nerve fibre types. An implantable electrode array comprising a plurality of electrodes is positioned proximal to the mixed nerve. An electrical stimulus is delivered from at least one nominal stimulus electrode of the implantable electrode array, in accordance with a set of stimulus parameters. A recording of the electrophysiological response evoked by the electrical stimulus is obtained from at least one nominal recording electrode of the implantable electrode array. The recording is analysed by assessing one or more selected characteristics of the recording, and from the observed selected characteristics a level of recruitment of one or more fibre types recruited by the electrical stimulus is identified. The stimulus parameters are refined in a manner to effect selective recruitment of one or more fibre types relative to other fibre types of the mixed nerve.

Abstract: The present disclosure provides a method and system for treating affective disorders such as depression and/or anxiety and/or related disorders through neuromodulatory intervention that includes brain targets within the orbitofrontal cortex (OFC). This method includes the application of electrical stimulation through an electrical signal generator device where the distal end of the device comprises at least one stimulating electrode in contact with the OFC. The treatment system includes patient selection, implantation of at least one stimulating electrode in contact with the OFC, acute or chronic electrical stimulation of the OFC, and evaluation of the effects of stimulation on clinical symptoms and status.

Abstract: An unattended approach can increase the reproducibility and safety of the treatment as the chance of over/under treating of a certain area is significantly decreased. On the other hand, unattended treatment of uneven or rugged areas can be challenging in terms of maintaining proper distance or contact with the treated tissue, mostly on areas which tend to differ from patient to patient (e.g. facial area). Delivering energy via a system of active elements embedded in a flexible pad adhesively attached to the skin offers a possible solution. The unattended approach may include delivering of multiple energies to enhance a visual appearance.

Abstract: A portable complex sensor device for measuring multiple items of biometric information, according to the present invention, comprises: a plurality of electrodes for receiving the biometric information; a plurality of biometric information measuring circuits for measuring the biometric information received from the plurality of electrodes; a plurality of current sensors which are always supplied with power so as to sense electric current when an object to be measured contacts the electrodes; a wireless communication means for transmitting and receiving data to and from a smart phone; and a microcontroller for controlling the power supply of a battery by being operated in a sleep mode or an active mode on the basis of whether the current sensors have sensed the electric current.

Abstract: A medical procedure for treating human male and female patients suffering from erectile or sexual dysfunction, respectively, with focused extracorporeal shockwave therapy applied to strategic, gender-specific anatomical regions to improve sexual function. Some or all of the gender-specific anatomical regions may be anesthetized using a topical or local anesthetic, and focused extracorporeal shockwaves are applied to the anatomical regions at predetermined bar values, frequencies, and number of shockwave pulses, based on the severity of the sexual dysfunction. Focused extracorporeal shockwaves may be used in addition to convention methods of treating both erectile and sexual dysfunction.
