Abstract: The present invention provides an intravascular blood pump comprising an expandable and collapsible region distal to a pump assembly. In some embodiments, the expandable and collapsible region may comprise expandable and collapsible proximal and/or distal transition sections adjacent a central expandable and collapsible region. Support structure, e.g., an expandable and collapsible stent may comprise at least a part of the expandable and collapsible region.

Abstract: An implantable system includes a first leadless pacemaker (LP1) implanted in or on a first chamber of a heart and a second leadless pacemaker (LP2) implanted in or on a second chamber of the heart. The LP1 is configured to time delivery of one or more pacing pulses delivered to the first chamber of the heart based on timing of cardiac activity associated with the second chamber of the heart detected by the LP1 itself. The LP1 is also configured to transmit implant-to-implant (i2i) messages to the LP2. The LP2 is configured to time delivery of one or more pacing pulses delivered to the second chamber of the heart based on timing of cardiac activity associated with the second chamber of the heart as determined based on one or more i2i messages received by the LP2 from the LP1.

Closed-loop transcranial stimulation and monitoring is also disclosed in which the patient is engaged in a cognitive task.

Abstract: An auscultatory sound signal acquired by a recording module is coupled through a high-pass filter having a cut-off frequency in the range of 3 to 15 Hz and subsequently filtered with a low-pass filter, and optionally subject to variable-gain amplification under external control—via a USB or wireless interface—of an associated docking system, responsive to the resulting processed auscultatory sound signal. A sound generator in the docking system generates an associated test signal having an integral number of wavelengths for each of a plurality of frequencies. The test signal is applied to a corresponding auscultatory sound-or-vibration sensor to test the integrity thereof. Resulting sound signals recorded by the recording module are analyzed using a Fourier Transform to determine sensor integrity.

Those sensor readings can then be compared by a processor component to derive a cardiac performance indicator relating to the patient.

Abstract: Medical device systems, methods, and algorithms are disclosed for providing complex stimulation waveforms. The waveforms may selectively modulate or activate specific neural targets or selected ratios of specific neural targets. Some of the waveforms include pre-pulse phases defined by parameters, the value of which changes during the pre-pulse phase. Also disclosed herein are graphical user interfaces (GUIs) that allow the selection of waveforms configured to selectively modulate or activate specific neural targets or selected ratios of the neural targets. Adjustable parameters of the waveforms are adjusted automatically based on selection of user-defined parameters.

Abstract: An energy harvester converts into electrical energy the external stresses applied to the implant at the heartbeat rhythm. This harvester comprises an inertial unit and a transducer delivering an electrical signal that is rectified and regulated for powering the implant and charging an energy storage component. The charge level of the energy storage component is compared with a lower threshold to detect an insufficient charge, and a dynamic charging control circuit modifies, as and whenever necessary, and if the current patient's state allows it, a stimulation parameter in a direction liable to increase in return the mean level of the mechanical energy that is produced and harvested.

The present invention identifies areas on vessel walls that are innervated with nerves; provides indication on whether energy is delivered accurately to a targeted nerve; and provides immediate post-procedural assessment of the effect of energy delivered to the nerve. The method includes at least the steps to evaluate a change in physiological parameters after energy is delivered to an arterial wall; and to determine the type of nerve that the energy was directed to (none, sympathetic or parasympathetic) based on the evaluated results. The system includes at least a device for delivering energy to the wall of blood vessel; sensors for detecting physiological signals from a subject; and indicators to display results obtained using this method.
