Conference Paper
Full-text available
In the previous years, it has been shown that ionic liquids (IL) are good candidates as base material for thermo-electric generators (TEG). Having identified promising ILs, the next step is building a module integrating those liquids and enabling its use with consumer devices. To keep the flexibility given by a liquid TEG, all the involved material...

In previous work it was shown that Ionic Liquids as active substances in thermoelectric generators have the potential to reduce the thermal conductivity as compared to Solid State materials used in conventional TEGs. Furthermore, it was observed that the Seebeck coefficient could be significantly increased. After a large variety of experiments, it...

This report describes the initial clinical results with a newly designed guiding catheter and an 'over the wire' pacing lead based on angiolasty technology to stimulate the left ventricle using the transvenous route via the coronary sinus (OTW-CV lead). In 75% of the 15 patients (6 males, 9 females, mean age of 53 +/- 9 years) with congestive heart...
Article
Atrio-biventricular pacing (ABP) has recently been proposed for treating patients (pts) with drug refractory heart failure (HF) and intraventricular conduction delay (ICD). The aim of this study was to evaluate long-term effects of ABP on cardiac performance and clinical status in pts with severe congestive HF and ICD. Inclusion criterias were chro...

Article
Pressure measuring systems using fluid-filled catheters can result in the recording of distorted pressure waveforms. It results in phase delay, overestimation of systolic and, to a lesser extent, of diastolic pressure. We designed and evaluated a method to correct this pressure waveform distortion using an appropriate transfer equation obtained fro...
Article
We tested the hypothesis that right heart failure during endotoxin shock may result from altered ventriculovascular coupling responsible for impeding power transfer to the pulmonary circulation. The changes in vascular pulmonary input impedance and right ventricular contractility produced by low-dose endotoxin infusion were studied in 6 intact anes...
Article
In 11 anaesthetised pigs the accuracy of the three-element (WK3) and the four-element (WK4) Windkessel models to describe hemodynamic properties of the pulmonary circulation was compared during six different experimental conditions increasing pulmonary arterial pressure: increase in left atrial pressure, increase in alveolar pressure, increase in p...
Conference Paper
Fluid-filled catheter-pressure transducer systems are often used to measure pressure in the arterial system. An index is proposed to appreciate, in such systems, the distortion of input impedance at each frequency. Effects on the evaluation of input impedance and some usual derived parameters such as zero-phase frequency, distance to the effective...
