20130025122 | METHOD OF ASSEMBLING AN IMPLANTABLE MEDICAL LEAD HAVING PASSIVE LOCK MECHANICAL BODY TERMINATIONS - Disclosed herein is a method of assembling an implantable medical lead configured to receive a stylet. The lead is provided with a tubular insulation layer, an electrode is disposed on the tubular insulation layer, an electrical conductor is routed through the tubular insulation layer, and a stylet stop is inserted into a distal end of the tubular insulation layer. The electrical conductor is directly and mechanically connected to the stylet stop and is in electrical communication with the electrode. | 01-31-2013 |
20130030509 | IMPLANTABLE MEDICAL LEAD HAVING PASSIVE LOCK MECHANICAL BODY TERMINATIONS - Disclosed herein is an implantable medical lead configured to receive a stylet. The lead may include a tubular body and a structure. The tubular body may include a distal end and a proximal end. The body may be configured to receive the stylet. The structure longitudinally may extend through the body between the distal end and the proximal end. The structure may be anchored within the body such that a tensile force arising within the body by the stylet being extended through the body causes the tensile force to be substantially carried by the structure. | 01-31-2013 |
20130053714 | SYSTEM AND METHOD FOR DETECTING AND CORRECTING ATRIAL UNDERSENSING - A method for operating an implantable medical device includes delivering a plurality of pacing pulses to an atria of a patient's heart and monitoring intrinsic atrial activity to detect intrinsic atrial contractions between one or more of the plurality of pacing pulses. The method further includes detecting atrial undersensing as a function of the detection of intrinsic atrial contractions. | 02-28-2013 |
20130066181 | IMPLANTABLE HEMODYNAMIC MONITOR AND METHODS FOR USE THEREWITH - Provided herein are implantable systems that include an implantable photoplethysmography (PPG) sensor, which can be used to obtain an arterial PPG waveform. In an embodiment, a metric of a terminal portion of an arterial PPG waveform is determined, and a metric of an initial portion of the arterial PPG waveform is determined, and a surrogate of mean arterial pressure is determined based on the metric of the terminal portion and the metric of the initial portion. In another embodiment, a surrogate of diastolic pressure is determined based on a metric of a terminal portion of an arterial PPG waveform. In a further embodiment, a surrogate of cardiac afterload is determined based on a metric of a terminal portion of an arterial PPG waveform. | 03-14-2013 |
20130123872 | LEADLESS IMPLANTABLE MEDICAL DEVICE WITH DUAL CHAMBER SENSING FUNCTIONALITY - A leadless implantable medical device (LIMD) is provided with dual chamber sensing functionality, without leads, despite the fact that the entire device is located in one chamber. In one embodiment, the LIMD senses local activity in the right atrium (RA) and local activity in the right ventricle (RV), even though it is entirely located in the RA. The sensing electrodes enable sensing in different chambers of the heart while reducing cross talk interference and thus provide accurate tracking of myocardial contraction in multiple chambers. | 05-16-2013 |
20130150913 | METHOD AND SYSTEM FOR IDENTIFYING A POTENTIAL LEAD FAILURE IN AN IMPLANTABLE MEDICAL DEVICE - A method for detecting potential failures by a lead of an implantable medical device is provided. The method includes sensing a first signal over a first channel between a first combination of electrodes on the lead and sensing a second signal from a second channel between a second combination of electrodes on the lead. The method determines whether at least one of the first and second signals is representative of a potential failure in the lead and identifies a failure and the electrode associated with the failure based on which of the first and second sensed signals is representative of the potential failure. Optionally, when the first and second sensed signals are both representative of the potential failure, the method further includes determining whether the first and second sensed signals are correlated with one another. When the first and second sensed signals are correlated, the method declares an electrode common to both of the first and second combinations to be associated with the failure. | 06-13-2013 |

20130053919 | IMPLANTABLE SYSTEMS AND METHODS FOR MONITORING BNP LEVELS, HF AND MI - Methods for monitoring a patient's level of B-type natriuretic peptide (BNP), and implantable cardiac systems capable of performing such methods, are provided. A ventricle is paced for a period of time to provoke a ventricular evoked response, and a ventricular intracardiac electrogram (IEGM) indicative of the ventricular evoked response is obtained. Based on the ventricular IEGM, there is a determination of at least one ventricular evoked response metric (e.g., ventricular evoked response peak-to-peak amplitude, ventricular evoked response area and/or ventricular evoked response maximum slope), and the patient's level of BNP is monitored based on determined ventricular evoked response metric(s). Based on the monitored level's of BNP, the patients heart failure (HF) condition and/or risks and/or occurrences of certain events (e.g., an acute HF exacerbation and/or an acute myocardial infarction) can be monitored. | 02-28-2013 |
20130060296 | ACQUIRING NERVE ACTIVITY FROM CAROTID BODY AND/OR SINUS - An exemplary includes acquiring an electroneurogram of the right carotid sinus nerve or the left carotid sinus nerve, analyzing the electroneurogram for at least one of chemosensory information and barosensory information and calling for one or more therapeutic actions based at least in part on the analyzing.
