| 20090102484 | BANDWIDTH EXPANSION IN MAGNETIC RESONANCE - A magnetic resonance imaging system includes a primary magnet and a secondary magnet operable to produce magnetic fields within a sample being imaged. The MRI system further includes at least one RF coil that is operable to receive electromagnetic frequencies from the sample. The RF coil is formed from tubing that serves as a cooling conduit through which flows a cooling fluid provided by a cooling source. The cooling fluid cools the RF coils to improve imaging of the sample. | 04-23-2009 |
| 20100066371 | INTRABODY MRI STACKED FLAT LOOP ANTENNAS AND RELATED SYSTEMS - Elongate intrabody MRI-antenna probes include opposing distal and proximal portions. The distal portion includes at least one multi-turn conductor arranged as a stack of substantially flat loops, each with a substantially rectangular elongate shape. A flat loop can reside on each of a plurality of adjacent vertically stacked substantially planar layers, the flat loops cooperate to define a MRI receive antenna. | 03-18-2010 |
| 20100137704 | MEDICAL MATS WITH ELECTRICAL PATHS AND METHODS FOR USING THE SAME - The disclosure describes medical mats that provide electrical paths with connectors that connect to various electronic medical or surgical tools. The medical mats can reduce the lengths of cables and define routes that preventing cross-over, looping and/or bunching of loose lengths of long cables. | 06-03-2010 |
| 20100217113 | CABLE MANAGEMENT SYSTEMS FOR MRI SYSTEMS AND RELATED METHODS - The disclosure describes cable management systems that provide adjustable lengths of cables that connect to various electronic medical or surgical tools. The systems can reduce the lengths of loose or hanging cables and define routes that preventing cross-over, looping and/or bunching of loose lengths of long cables. | 08-26-2010 |
| 20100317961 | MRI-Guided Devices and MRI-Guided Interventional Systems that can Track and Generate Dynamic Visualizations of the Devices in near Real Time - An MRI-guided medical device includes an elongated sheath, an elongated dilator, and an elongated needle. The sheath has a distal end, an opposite proximal end, and a central lumen extending between the proximal and distal ends. The sheath comprises MRI-compatible material and includes a tracking member located adjacent to the sheath distal end that is visible in an MRI image. The dilator comprises MRI-compatible material and is movably disposed within the sheath lumen. A distal end of the dilator is configured to extend outwardly from the sheath distal end and dilator includes at least one tracking member that is visible in an MRI image. The needle is movably disposed within the dilator lumen and is movable between stored and operative positions relative to the dilator. An RF shield may be coaxially disposed within the elongated sheath so as to surround a portion of the sheath central lumen. | 12-16-2010 |
| 20100317962 | MRI-Guided Devices and MRI-Guided Interventional Systems that can Track and Generate Dynamic Visualizations of the Devices in near Real Time - An MRI-compatible catheter includes an elongated flexible shaft having opposite distal and proximal end portions. A handle is attached to the proximal end portion and includes an actuator in communication with the shaft distal end portion that is configured to articulate the shaft distal end portion. The distal end portion of the shaft may include an ablation tip and includes at least one RF tracking coil positioned adjacent the ablation tip that is electrically connected to an MRI scanner. The at least one RF tracking coil is electrically connected to a circuit that reduces coupling when the at least one RF tracking coil is exposed to an MRI environment. Each RF tracking coil is a 1-10 turn solenoid coil, and has a length along the longitudinal direction of the catheter of between about 0.25 mm and about 4 mm. | 12-16-2010 |
| 20100321020 | BANDWIDTH EXPANSION IN MAGNETIC RESONANCE - An apparatus for use in a magnetic resonance examination includes a radio frequency receive coil ( | 12-23-2010 |
