Abstract
Abstract An intra-aortic balloon pump (IABP) having improved automated electrocardiogram (ECG) based intra-aortic balloon deflation timing. Said IABP capable of automatically determining to either deflate the intra-aortic balloon upon the detection of the next cardiac cycle (non-predictive deflation) or at an earlier point derived from predicting the occurrence of the next cycle (predictive deflation). This automated determination is based upon a quantitative assessment of the performance of the intra-aortic balloon pump in predicting the prevailing cardiac rhythm.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
84 words
An intra-aortic balloon pump comprising a balloon inflation and deflation means and a control logic module for controlling said balloon inflation and deflation means, said control logic module having a setting in which it bases its decision of automatically activating and/or deactivating a non-predictive deflation mode on its assessment of its performance in a predictive deflation mode, said control logic module assessing the performance of the intra-aortic balloon pump by comparing prediction errors and consequently deflation timing errors to total diastolic augmentation time available.
Claim 2
Dependent Claim
84 words
An intra-aortic balloon pump comprising a balloon inflation and deflation means and a control logic module for controlling said balloon inflation and deflation means, said control logic module having a setting in which it bases its decision of automatically activating and/or deactivating a non-predictive deflation mode on its assessment of its performance in a predictive deflation mode, said control logic module assessing the performance of the intra-aortic balloon pump by comparing prediction errors and consequently deflation timing errors to total diastolic augmentation time available.
Claim 3
Dependent Claim
88 words
An intra-aortic balloon pump comprising a balloon inflation and deflation means and a control logic module for controlling said balloon inflation and deflation means, said control logic module having a setting in which it bases its decision of automatically activating and/or deactivating a non-predictive deflation mode on its assessment of its performance in a predictive deflation mode, said control logic module assessing the performance of the intra-aortic balloon pump by comparing actual diastolic augmentation for a given beat to the total potential diastolic augmentation that can be realized.
Claim 4
Dependent Claim
88 words
An intra-aortic balloon pump comprising a balloon inflation and deflation means and a control logic module for controlling said balloon inflation and deflation means, said control logic module having a setting in which it bases its decision of automatically activating and/or deactivating a non-predictive deflation mode on its assessment of its performance in a predictive deflation mode, said control logic module assessing the performance of the intra-aortic balloon pump by comparing actual diastolic augmentation for a given beat to the total potential diastolic augmentation that can be realized.
Claim 5
Dependent Claim
21 words
The intra-aortic balloon pump as claimed in claim 1 or 2 wherein the non-predictive deflation mode is a P-wave deflation mode.
