20100113958 | Active Implantable Medical Device Integrating Spirometric Means for Diagnosing Lung Diseases - An active implantable medical device, integrating a spirometric function for the diagnosis of lung diseases is disclosed. The active implantable medical device measures the respiratory activity of a patient to collect a transthoracic impedance signal according to changes in lung volume. The active implantable medical device comprises a spirometer function produces, from the transthoracic impedance signal collected over a respiratory cycle, a characteristic curve that couples of flow values (dV/dt) as a function of pulmonary volume (V) that represents a spirometric characteristic (S) of a patient. An spirometric analysis is performed to deduce from the spirometric characteristic (S) at least one parameter of the patient's pulmonary status and to produce a diagnostic indicator based on the comparison of the at least one parameter with a predetermined reference value. | 05-06-2010 |

20140336720 | IMPLANTABLE CARDIAC PROSTHETIC FOR RESYNCHRONIZATION BY BIVENTRICULAR PACING USING REVERSE REMODELING - An implantable prosthetic device for cardiac resynchronization by biventricular pacing including a cardiac reverse remodeling. The combination of the stimulation sites, the atrioventricular delay (AVD), and the interventricular delay (VVD) together define a common pacing configuration, temporarily switched from an original pacing configuration (a) to a modified pacing configuration (b) in a direction opposite to that of an optimization of the hemodynamic parameters, to cause an immediate change in the response to controlled stimulation of the myocardium. This response is assessed based on: the maximum value (P (b, a)) achieved by the peak-to-peak (PEA (i)) of the first peak of endocardial acceleration (PEA) after a pacing configuration change, the mean PEA value (A (b, a)) after stabilization, the PEA variability (V (b, a)) around this average value, and the duration (T (b, a)) of stabilization after the pacing configuration change. The analysis defines temporary, occasionally harmful stimulation sequences, forcing the myocardium to reverse remodeling, for, in the long term, improving its response in terms of pressure, ejected volume, and filling and ejection times. | 11-13-2014 |
