20120197331 | ISOLATING LEAD CONDUCTOR FOR FAULT DETECTION - Systems and methods for providing a cardiac stimulus device lead having fault tolerance and fault isolation are disclosed. A medical electrical lead is provided according to one aspect. According to one embodiment, the lead includes a first conductor and a second conductor for transmitting an electrical pulse from a pulse generator. The lead further includes a switching mechanism, a first electrode, and a lead assessment circuit. The switching mechanism selectively couples the first conductor to the first electrode. The first electrode is decoupled during a test phase and the switching mechanism directly couples the first conductor to the second conductor. The lead assessment circuit processes a signal associated with the electrical properties of the lead to determine whether the lead is exhibiting a lead related condition. | 08-02-2012 |
20120197365 | ISOLATED LEAD CONDUCTOR MEASUREMENTS FOR FAULT DETECTION - This disclosure relates to a medical electrical lead having fault detection and fault isolation. The lead may include a first conductor coupled to a first electrode and a second conductor coupled to a second electrode. A capacitor is disposed within the lead and selectively coupled to the first and second conductors of the lead. The capacitor is charged in a test mode of operation after the first and second electrodes have been isolated from the conductors via an isolation mechanism and the capacitor will discharge through the first and second conductors. The capacitor discharge morphology is processed to detect lead-related conditions. | 08-02-2012 |
20120316416 | Fault Tolerant Methods and Architectures for Embedded Intelligence in Medical Leads - The present disclosure pertains to methods, devices and systems for detection of a lead-related condition in a medical electrical lead. In accordance with the disclosure, a physiological waveform interpreter module embedded within the lead functions to sense the occurrence of a cardiac event and to generate a minimal impact signal. In an example implementation, the physiological waveform interpreter module is disposed proximate to the sensing site or vicinity of cardiac signals. The physiological waveform interpreter module transmits the minimal impact signal that may include one or more predetermined properties to a remotely located lead monitoring module upon sensing a cardiac event. The lead monitoring module receives and processes the minimal impact signal to determine whether a cardiac depolarization has occurred and simultaneously verify the integrity of the transmission medium. | 12-13-2012 |
20120316621 | Method and Apparatus to Manage Lead-Related Conditions for Fault Tolerance Enhancements - The disclosure describes methods and devices for providing early indicators of a lead-related condition in a medical electrical lead. Among other things, the methods and devices will detect, obtain, or provide indicators of static or intermittent disruptions in a conductive pathway of the lead based on changes in conductive continuity properties of a medical electrical lead. The conductive behaviors and properties will be managed to facilitate signal stability and fidelity. In some embodiments, the methods and devices may include functions to enable one or more of monitoring a lead's conductive pathway, detecting static and transient behaviors of the conductive pathway, stabilizing the monitored pathway, reconfiguring the pathway, and providing lead-related condition data to an associated implantable medical device. The early indicators may be generated in a real-time, continuous manner to provide early detection and notification of lead degradation. | 12-13-2012 |

20140031660 | ISOLATING LEAD BODY FOR FAULT DETECTION - Techniques are described for detecting lead-related conditions for implantable electrical leads. In some of the described embodiments, an implantable electrical lead assembly is provided with a coupling member for connecting a conductor and associated insulator(s) to an electrode/sensing element. The implantable medical device controls and performs a measurement of an electrical property of the electrical lead during periods when the conductor is decoupled from the electrode/sensing element. An indication of a lead-related condition is derived based on the measured electrical property. The lead-related condition may be associated with an insulator of a lead body of the electrical lead. | 01-30-2014 |

20100266222 | BAG - A thermoplastic bag for storing food items may include a first sidewall and an opposing second sidewall joined to the first sidewall to define an interior volume. The first and second sidewalls may be made from pliable, sheet-like thermoplastic web material. The sidewalls may be formed with a pattern of ribs. When a tensioning force is applied to the sidewall, the ribs may open so that the sidewall may become generally more planar. Opening the ribs may cause the sidewalls to stretch or expand thereby adding to the overall area of the bag. The thermoplastic material may have a shape memory characteristic that may cause the ribs to reform after the tensioning force is alleviated. | 10-21-2010 |
