摘要:
A system and method for decompensation prediction of a heart failure patient with one or more injectable detecting systems communicating wirelessly with a remote monitoring system. The system includes one or more injectable detecting systems having a plurality of sensors that provide an indication of at least one physiological event of a patient, a wireless communication device coupled to the one or more injectable detecting systems and configured to transfer patient data directly or indirectly from the one or more injectable detecting systems to a remote monitoring system, and a remote monitoring system coupled to the wireless communication device, the remote monitoring system using processed data to determine heart failure status and predict impending decompensation of the patient.

A method carried out by an implantable medical device (IMD) for coordinating performance of one or more designated functions includes waiting in a low-power state for a predetermined event, detecting the predetermined event, and, responsive to detecting the predetermined event, searching for a wake-up command from a coordinating device implanted in the human body. The method further includes, receiving the wake-up command, and responsive to receiving the wake-up command, performing the one or more designated functions, and returning to the low-power state. A system includes a network of one or more implantable medical devices (IMDs) implanted in a human body. The system includes a satellite IMD operable to change between a plurality of power states, search for a wake-up command, and transmit an identification signal. The system may include a primary unit operable to receive the signal and coordinate a wake-up time based on the signal.

One embodiment of the present invention relates to a system for deriving physiologic measurement values that are relative to ambient conditions. In one embodiment, the system comprises an implantable medical device (“IMD”), an external computing device, and a backend computing system. The IMD determines an absolute physiologic parameter value within a patient's body, and communicates the absolute physiologic parameter value outside the patient's body, for example, to the external computing device. Further, the external computing device receives the absolute physiologic parameter from the IMD and communicates it to the backend computing system. The backend computing system receives the absolute physiologic parameter value and obtains an ambient condition value outside the body that can affect the absolute physiologic parameter value. The backend computing system then calculates a relative physiologic parameter value from the ambient condition value and the absolute physiologic parameter value, and in some embodiments, stores the relative physiologic parameter value in a storage location, such as a memory or database.
摘要:
All or a portion of a surface of an implantable sensor is covered with a biocompatible coating formed at least partially of a biomaterial matrix having properties that promote a substantially even growth of tissue cells over the surface of the coating. Additional materials, such as growth factors, agents that recruit endogenous stem cells, and cell adhesion motif arginine, glycine, aspartic acid may be included in the coating. Autologous cells may be added to the coating prior to implantation. The sensor surface may also be textured, by etching or abrading, in order to promote even tissue growth. Alternatively, the sensor surface may be covered with a coating having properties that inhibit the growth of tissue. These coatings may include a biomaterial, a biomaterial matrix having a drug, such as a sirolimus or a steroid, an active component, or a self assembled monolayer.

Systems and methods for correlating biometric trends with a related temporal event are disclosed. A preferred embodiment utilizes an implantable medical device comprising at least one sensor in electronic communication with a patient management system adapted to temporally analyze and correlate biometric data. Some embodiments of a system disclosed herein also can be configured as an Advanced Patient Management system that helps better monitor, predict and manage chronic diseases.
摘要:
A system and method for restoring a microprocessor-based system to a previously booted target state in which an image of memory and the processor registers in the previously booted state is saved and stored in a storage device. A restore routine executing in ROM retrieves the image from the storage device and restores the system memory and processor registers to the target state. An operating system return routine then returns control of the system to the operating system software. In an exemplary implementation, a system in accordance with the invention is incorporated into a microprocessor-based external programmer for a cardiac rhythm management device in order to allow quick starting of the programmer from a powered down condition without going through a time consuming boot process.
