20080199548 | Efficient method for producing compositions enriched in total phenols - A product made by a process which results in compositions enriched in total phenols includes purification steps not involving the addition of bisulfite ions. The enriched compositions are characterized as containing monomeric, oligomeric and polymeric phenols, total phenol concentration >12% and exhibiting in vitro COX-2 inhibitory activity enhanced by a factor of at least 2.5 over a standard aspirin dose of 660 μg/mL. | 08-21-2008 |
20080207770 | COMPOSITIONS ENRICHED IN PHENOLIC COMPOUNDS AND METHODS FOR PRODUCING THE SAME - Provided are processes for the preparation of compositions enriched in phenolic compounds from a crude plant extract. One process includes a novel column purification step using a polymer resin that releasably adsorbs the phenolic compounds but does not retain polar non-phenolic compounds, wherein the resin comprises aromatic rings substituted with one or more electron-withdrawing groups. This invention also includes compositions enriched in phenolic compounds. This invention encompasses methods of using the phenolic-enriched compositions for treating warm-blooded animals, including humans, infected with paramyxovaridae such as respiratory syncytial virus, orthomyoxovaridae such as influenza A, B, and C, parainfluenza, Herpes viruses such as HSV-1 and HSV-2, and Flaviviruses such as West Nile Virus, and for treating inflammation such as caused by arthritis, stress and digestive disease. The compositions are also useful as meat additives to inhibit food-borne pathogens. | 08-28-2008 |

20100168819 | RF TELEMETRY LINK QUALITY ASSESSMENT SYSTEM AND METHOD - A system comprises an implantable medical device (IMD), a external user interface device, and a radio frequency link quality assessment (LQA) device. The external user interface device and the IMD are adapted to potentially use one or more of a plurality of available wireless communication channels to communicate. The LQA device is positioned to receive a radio frequency communication between the IMD and the external user interface device. At least one of the IMD, the external user interface device, and the LQA device is adapted to evaluate signal and noise strength of the available channels to determine respective signal and noise levels for each channel by using the noise level for the target channel and interference potential for corresponding adjacent channels to the target channel as inputs to a function to provide a value for a LQA for the target channel, and select a preferred communication channel based on the LQA value for each of the available wireless communication channels. | 07-01-2010 |
20110313494 | PACEMAKER RF TELEMETRY REPEATER AND METHOD - A system and method for repeating radio frequency (RF) transmissions between a programmer and an implantable medical device (IMD) is provided. One aspect of this disclosure relates to an RF repeater. According to various embodiments, the repeater includes a first antenna and a first communication circuit electrically connected to the first antenna. The first communication circuit is adapted to communicate with an IMD, the IMD including a built-in active telemetry transceiver, over a first channel. The device also includes a second antenna and a second communication circuit electrically connected to the second antenna. The second communication circuit is adapted to communicate with a programmer over a second channel different from the first channel. The device also includes a control circuit coupled to the first and second communication circuits. The control circuit is adapted to enable or disable the first and second communication circuits. Other aspects and embodiments are provided herein. | 12-22-2011 |
20120046559 | CROSS-CHECKING OF TRANSTHORACIC IMPEDANCE AND ACCELERATION SIGNALS - A first chamber minute ventilation rate is determined based on a first transthoracic impedance signal received from a first chamber of a heart and a second chamber minute ventilation rate is determined based on a second transthoracic impedance signal received from a second chamber of the heart. A processor compares the minute ventilation rates to determine a rate. In one embodiment, an accelerometer sensor provides data for evaluating propriety of a rate. Before implementing a rate change, signals from multiple sensors are cross-checked. | 02-23-2012 |

20100262032 | Systems and Methods for Indicating Aberrant Behavior Detected by an Implanted Medical Device - Various systems and methods provide for intervening where aberrant heart and/or respiratory functionality is detected. For example, some embodiments of the present invention provide a monitor capable of detecting the occurrence of various aberrant events, and in some cases for intervening in the event. In some cases, a pacemaker or some other medical device detects an abnormality, and an information signal indicating the detected abnormality is transmitted from the pacemaker to a bedside monitor or some other monitor associated with the patient. Based on the received information signal, the bedside monitor can deliver an appropriate therapy. Such a therapy can be, but are not limited to, the sounding of an audible alarm to awake the patient, and/or the programming of a medical device implanted in the patient. Further, in some cases, the detected aberrant behavior and/or events surrounding the aberrant behavior can be transmitted from the bedside monitor to a remote monitor. Information can be retrieved from the remote monitor by a clinician and used in real time, or at a later time to diagnose and/or treat the patient. | 10-14-2010 |
20110071587 | Adaptive Safety Pacing - Methods and systems involve adjusting an energy used for safety pacing based on the capture threshold. The safety pacing energy may be adjusted prior to a capture threshold test. During the capture threshold test, backup safety paces are delivered using the adjusted pacing energy. Following suspension of automatic capture verification, the device may enter a suspension mode. During the suspension mode, safety pacing pulses are delivered using a pacing energy adjusted based on capture threshold. | 03-24-2011 |
