摘要:
The temperature mapping balloon of the present invention provides a device for locating inflammation and increased metabolic activity associated with conditions such as vulnerable plaque, by mapping temperature of a body lumen, such as an artery or blood vessel. The temperature mapping balloon comprises a balloon with a thermal mapping coating disposed on the inside or outside of the balloon. The thermal mapping coating can be a thermochromic coating that changes color in response to temperature or a sensor coating comprising a plurality of temperature sensors.
摘要:
A method and apparatus for determining vulnerable plaque in a cardiovascular lumen is disclosed. In one embodiment, a guide member comprising a temperature sensor and a distance sensor are inserted into the cardiovascular lumen. The temperature of the cardiovascular wall is measured with the temperature sensor, and the distance from the temperature sensor to the cardiovascular wall is determined. The cardiovascular wall temperature is adjusted based on the distance determination, and the vulnerable plaque is determined based on the adjusted wall temperature measurement.

摘要:
A data collection system includes remote, implantable sensors for monitoring one or more patient parameters, collecting and processing data from those sensors and utilizing that data in the performance of a clinical study of a drug or other pharmacological agent. The system assists with preparation of a protocol for a clinical trial; presentation of that protocol; assuring compliance with the protocol; and generating useful results from data collected via the system and externally for presentation to an approval forum.
摘要:
A PCI card is inserted through an I/O opening in a computer panel. On one edge of the card is a cover from one end of which projects a tab. A resilient gasket is attached to the panel to create a flexible EMC seal around the opening. Preferably the gasket is formed of tin-plated beryllium copper. The gasket has alternate staggered spring fingers oriented opposite to the direction of insertion of the PCI card. To retain the gasket the panel is formed with slots at either end and an outward struck projection at the middle. The gasket is formed with a tongue at either end to be inserted in one of the slots and a punched-out opening to receive the projection.
摘要:
A medical device for implantation within a patient comprising a lead body including a conductor within the lead body and a transducer supported by the lead body. The conductor is electrically coupled to the transducer by a conductive fluid, paste or gel. The conductive fluid, paste or gel may be contained within a well in the lead body. The transducer may be a MEMS chip and/or an integrated circuit and may perform any of a variety of functions such as sensing physiological data.

An intelligent patient management system collects data from a variety of sources, processes that information, and provides relevant information to an appropriate caregiver in context at the proper time. The system has multiple information sources available from which to gather additional information based upon conclusions drawn or issues identified from the patient data.

PCI cards are plugged into vertical risers, the lower edges of which have been plugged into a motherboard. This involves a considerable force being applied to the riser card, both during insertion and removal, and may damage the card or the underlying motherboard. A support for the top edge of the riser card clips onto the upper end thereof. Rearward extensions of the support are gripped by tabs struck out of a wall of the enclosure.
摘要:
In general, the invention is directed to methods and devices for determining an ion concentration in the extracellular fluid of a patient. As examples, the ion may be one or more of potassium, sodium, chloride, or calcium. A system includes an electrode deployed in or near a tissue, such as a skeletal muscle, of the patient. A pulse generator supplies one or more stimulations to the tissue, and a sensor, such as an accelerometer, detects the response of the tissue to the stimulations. A processor determines a concentration of ions in the extracellular fluid as a function of the response. The system may detect an ion imbalance based upon the determined concentration of ions.
