摘要： The lead configuration enhances the sensing characteristics of the lead and provides for stable location of the electrodes in the coronary sinus. The J-shaped bend in the distal portion of the lead body spaces the distal tip of the lead body less than about 0.9 inches laterally from the portion of the lead body that is proximal to the bend. The tip of the lead body is provided with a pacing/sensing electrode and the curved portion of the J-shaped bend carries an elongated coil electrode that serves as an indifferent electrode for pacing and sensing. For left atrial pacing, the lead tip electrode is located adjacent the wall of the coronary sinus closest to the left atrium, and the indifferent electrode is located adjacent the opposite wall of the coronary sinus, closer to the left ventricle. To enhance spatial distribution of the indifferent electrode and provide for greater averaging of the ventricular signal, which in turn reduces the far field of the ventricular signal, the indifferent electrode extends over 10-50 millimeters or multiple spaced indifferent electrodes are used.

摘要： A lead and a lead system for dispersion of a cardioversion/defibrillation electrode formed of one or more small diameter defibrillation electrodes in a heart chamber and for attaching a pace/sense electrode in contact with the heart. The small diameter defibrillation electrode or electrodes extend distally from the distal end of the lead body. If multiple electrodes are employed, they are preferably biased to spread apart when unrestrained and have a cross-section size small enough to be inserted into interstices of trabeculae in the ventricular chamber. The distal ends of the defibrillation electrodes may be free of attachment to the lead body or may be attached by a weak bond to the distal portion of the lead.

摘要： A computer implemented method and system is provided for managing neural stimulation therapy. The method comprises under control of one or more processors configured with program instructions. The method delivers a series of candidate stimulation waveforms having varied stimulation intensities to at least one electrode located proximate to nervous tissue of interest. A parameter defines the candidate stimulation waveforms is changed to vary the stimulation intensity. The method identifies a first candidate stimulation waveform that induces a paresthesia-abatement effect, while continuing to induce a select analgesic effect. The method further identifies a second candidate stimulation waveform that does not induce the select analgesic effect. The method sets a stimulation therapy based on the first and second candidate stimulation waveforms.

摘要： Techniques are provided for use with an implantable medical device for assessing stroke volume or related cardiac function parameters such as cardiac output based on impedance signals obtained using hybrid impedance configurations that exploit a multi-pole cardiac pacing/sensing lead implanted near the left ventricle. In one example, current is injected between a large and stable reference electrode and a ring electrode in the RV. The reference electrode may be, e.g., a coil electrode implanted within the superior vena cava (SVC). Impedance values are measured along a set of different sensing vectors between the reference electrode and each of the electrodes of the multi-pole LV lead. Stroke volume is then estimated and tracked within the patient using the impedance values. In this manner, a hybrid impedance detection configuration is exploited whereby one vector is used to inject current and other vectors are used to measure impedance.

摘要： An implantable cardiac therapy device and methods of using a device including an implantable stimulation pulse generator, one or more implantable leads defining sensing and stimulation circuits adapted to sense and deliver therapy in at least one right side heart chamber, and an implantable controller in communication with the stimulation pulse generator and the one or more patient leads so as to receive sensed signals indicative of a patient's physiologic activity and deliver indicated therapy. The controller is adapted to monitor at least one indicator of cardiac dysynchrony and to compare the at least one indicator to a determined dysynchrony threshold. The threshold is determined for indications that the patient be further evaluated for cardiac resynchronization therapy. The controller is further adapted to set an alert when the at least one indicator exceeds the threshold to indicate to a clinician that evaluation for bi-ventricular pacing might be indicated.

摘要： Techniques are provided for use by implantable medical devices for controlling multi-site left ventricular (MSLV) pacing using a multi-pole left ventricular (LV) lead. In various examples, a reduced number of “V sense”, “RV pace”, and “LV pace” tests are performed to determine preferred or optimal interventricular pacing delays (VV) for use with MSLV pacing. Additionally, techniques are described for sorting the order by which LV sites are to be paced during MSLV pacing. Furthermore, techniques are described for detecting and addressing circumstances where AV/PV delays are longer than corresponding AR/PR delays during MSLV.

摘要： Techniques are provided for configuring filters for reducing heating within pacing/sensing leads of a pacemaker or implantable cardioverter-defibrillator that might occur due to induced currents during a magnetic resonance imaging (MRI) procedure or in the presence of other sources of strong radio frequency (RF) fields.

摘要： Techniques are provided for controlling spinal cord stimulation (SCS) or other forms of neurostimulation. Far-field cardiac electrical signals are sensed using a lead of the SCS device and neurostimulation is selectively delivering using a set of adjustable SCS control parameters. Parameters representative of cardiac rhythm are derived from the far-field cardiac electrical signals. The parameters representative of cardiac rhythm are correlated with SCS control parameters to thereby map neurostimulation control settings to cardiac rhythm parameters. The delivery of further neurostimulation is then controlled based on the mapping of neurostimulation control settings to cardiac rhythm parameters to, for example, address any cardiovascular disorders detected based on the far-field cardiac signals. In this manner, a closed loop control system is provided to automatically adjust SCS control parameters to respond to changes in cardiac rhythm such as changes associated with ischemia, arrhythmia or heart failure.

摘要： Methods and systems are provided for discriminating heart arrhythmias. The methods and systems include identifying an arrhythmia, recording a predetermined number of beats during the arrhythmia as a base arrhythmia (BA) beats; delivering anti-tachy pacing (ATP) therapy to at least one chamber of the heart. After delivering the ATP therapy, the methods and system record at least one return beat representing cardiac activity following the ATP therapy, determines whether the return beat originated in a reference chamber of the heart, compares a morphology of the return beat to a morphology of the BA beat; and declares a VT or SVT based on the comparing operation.

摘要： Techniques are provided for estimating left atrial pressure (LAP) or other cardiac performance parameters based on measured conduction delays. In particular, LAP is estimated based interventricular conduction delays. Predetermined conversion factors stored within the device are used to convert the various the conduction delays into LAP values or other appropriate cardiac performance parameters. The conversion factors may be, for example, slope and baseline values derived during an initial calibration procedure performed by an external system, such as an external programmer. In some examples, the slope and baseline values may be periodically re-calibrated by the implantable device itself. Techniques are also described for adaptively adjusting pacing parameters based on estimated LAP or other cardiac performance parameters. Still further, techniques are described for estimating conduction delays based on impedance or admittance values and for tracking heart failure therefrom.
