MagPro is a complete line of non-invasive Magnetic Stimulation Systems, including both dedicated and general-purpose stimulators.
Large, or Small Coils - circular or figure of 8? Large coils provide a high penetration depth, but are not very focused. The small coils are more focused, but have a relatively shallow penetration depth. Thus there is an inverse relation between penetration depth and focus.The coils come in many sizes and shapes. The two most commonly used coils are the circular shaped coil and the butterfly shaped coil also known as the “figure of 8” coil. Circular Coils When applying the circular coil, the induced current in the tissue occurs under the windings. A fairly large area of body tissue will be stimulated. The circular coil may be positioned conveniently over many parts of the body, and usually serves well as a “general purpose coil”. Butterfly Coils The Butterfly coils are more focused in comparison with the circular coils. The two windings are placed side-by-side, enabling the coil to stimulate structures with focus right under its center. The butterfly coil is useful in focused stimulation. Coils with Fluid Magnetic stimulating coils become warm during use, because energy is deposited in the coil due to electrical resistance. To prevent fast overheating in the coil, coils with a reservoir of fluid (F-coils) have been developed. The fluid partially absorbs the heat, enabling the coil to perform more stimuli. Coils with External Cooling Where a very high number of stimuli is required at High Repetition Rates and long pulse trains, extra cooling is necessary.Cool-Coils with external Cooler Unit fulfill these requirements. Useful Features Some of the coils include useful features, such as the trigger button in the handle for clinical operation, and the power control in the handle, making remote control of the amplitude possible. Customer Design and Modifications Customer designed coils are available as well as modification of existing coils, ranging from extending the coil cable to a complete change of geometry of the coil. Please contact MagVenture for further details. Coil Converter All coils are designed for use with MagPro and MagPro Compact*).*) Provided MagPro Compact is equipped with a Coil Converter, see accessories (Except for C-100, C-B60 and MMC-140-II).
