摘要： A method and apparatus for-recanalizing a substantially totally occluded vessel (310) in a subject (100). An image of the substantially totally occluded vessel (310) is obtained using magnetic resonance. A recanalization device (330) is guided using the obtained image. The occlusion is recanalized with the recanalization device (330). In one embodiment, a magnetic resonance signal is received with at least one external antenna (160) located external to the body of the subject (100). A map image of the occluded vessel (310) is generated using the signal received by the external antenna (160). A magnetic resonance signal is received with an internal antenna (350) positioned within the body of the subject (100), proximate to the occluded vessel (310). The map image of the occluded vessel (310) is locally enhanced using the signal received by the internal antenna (350).

摘要： Medical devices incorporate therein imaging materials having selected MRI detectable nuclei to provide useful magnetic resonance images of the medical devices and proximate body tissue. Also, a method generates MRI images of such a medical device, and involves performing first and second MRI processes on a body portion including at least a portion of the medical device to obtain, respectively, first and second image data. The first MRI process is adapted to detect MRI detectable nuclei present in the proximate body tissue, and the second MRI process is adapted to detect the selected MRI detectable nuclei contained in the device's imaging material. The selected MRI detectable nuclei incorporated in the imaging material is not the same nuclei that the first MRI process is adapted to detect. The second image data are combined with the first image data to produce image data for the medical device and the proximate body tissue.

摘要： Various configurations of systems that employ leadless electrodes to provide pacing therapy are provided. In one example, a system that provides multiple sites for pacing of myocardium of a heart includes wireless pacing electrodes that are implantable at sites proximate the myocardium using a percutaneous, transluminal, catheter delivery system. Each of the electrodes contains a source of electrical energy for pacing the myocardium and is adapted to receive electromagnetic energy from a source outside the myocardium. The system also includes a source adapted for placement outside the myocardium and that uses locally measured electrocardiograms to synchronize pacing of the heart by sending electromagnetic commands to the electrodes to pace the myocardium surrounding the electrodes. Also disclosed is various configurations of such systems, wireless electrode assemblies, and delivery catheters for delivering and implanting the electrode assemblies.

摘要： A high performance guide wire with a pressure sensor for measuring blood pressure, may utilize a single electrical lead connected to the guide wire. An integrated circuit, powered by the single electrical connection on the guide wire, may interface with the pressure sensor, and may convert pressure information to an encoded signal. The encoded signal may be detectable in the electrical circuit, and can be used to display a pressure waveform as detected by the pressure sensor. For example, when utilized for percutaneous coronary interventions, such a guide wire can provide high quality blood pressure measurements (e.g., for fractional flow reserve), while also possessing excellent steerability and handling characteristics for navigating tortuous anatomy.

摘要： Some embodiments of pacing systems employ wireless electrode assemblies to provide pacing therapy. The wireless electrode assemblies may wirelessly receive energy via an inductive coupling so as to provide electrical stimulation to the surrounding heart tissue. In certain embodiments, the wireless electrode assembly may include one or more biased tines that shift from a first position to a second position to secure the wireless electrode assembly into the inner wall of the heart chamber.
