Abstract: Featured is a reduction instrument being configured and arranged to allow correction of vertebral translation and applying distraction across a segment in an independent fashion. Such a reduction instrument embodies one or more identical modules that are configured as needed for correcting the deformity. In more particular embodiments, each of the one or more modules has two degrees of freedom (DOF) with uncoupled orthogonal translations. Such a reduction instrument allows the reorientation of the vertebral segment as needed via uncoupled orthogonal translations. Such a reduction instrument also is usable in combination with a plurality of vertebral anchors, such vertebral anchors being any such vertebral anchors as are know to those skilled in the art (e.g., conventional spinal pedicle screw instrumentation) or hereinafter developed so as to form a spinal implant system. Also featured are treatment methods utilizing such a reduction instrument.

Abstract: Featured is a device for NMR or MRI signals from excited nuclei as well as related apparatus, systems and methods. The device includes a strip array antenna including one or more conductor and N reactive tuning components, where N is an integer ?1 at least one of the N reactive components is electrically coupled to each of the one or more conductors as well as to ground/virtual ground. The apparent electrical length of the conductors is tuned with the reactive tuning components so it is equal to be about n?/4, where n is an integer ?1 and ? is the wavelength of the signal to be detected. The length of the strip also is such as to be substantially in the approximate range of 1.3 times the depth of interest. The strip conductors are also combined with loop coils to form quadrature detectors.

Abstract: Featured are a device with localized sensitivity to magnetic resonance signals, an imaging system using such a device and MRI methods for performing internal MRI or MRI Endoscopy. Such an MRI method includes introducing an MRI antenna or probe into the specimen to be imaged, the antenna being configured in accordance with the devices described herein, so that the spatial coordinate frame of imaging is inherently locked or defined with respect to the introduced antenna thereby providing imaging of the specimen from the point of view of the antenna. Further such imaging is conducted so that the MRI signal is confined substantially to a volume with respect to a particular region of the antenna or probe.

Abstract: Some embodiments are directed to MRI/RF compatible medical interventional devices.

Abstract: MRI/RF compatible leads include at least one conductor, a respective conductor having at least one segment with a multi-layer stacked coil configuration. The lead can be configured so that the lead heats local tissue less than about 10 degrees Celsius (typically about 5 degrees Celsius or less) or does not heat local tissue when a patient is exposed to target RF frequencies at a peak input SAR of at least about 4 W/kg and/or a whole body average SAR of at least about 2 W/kg. Related leads and methods of fabricating leads are also described.

Abstract: Use of stimuli in order to provide association with a training regime or other behavior modification technique is known. With regard to olfactory stimulation it will be appreciated that it is necessary that the olfactory is actively provided in the sense the it is not a continuous stimulation but provided in pulses for regular association. Without such distinct presentation of the olfactory stimulus a user may become desensitized. In order to achieve this the present olfactory stimulator comprises a regulator and specific delivery techniques such as the use of a fan or piston to direct the olfactory towards the user's nose.

Abstract: The use of stimuli in order to create association between training regimes subconsciously is known. Unfortunately, in highly noisy and other polluted environments it is difficult to provide ongoing reinforcement of previous behavior modification and training. By providing a stimulus phrase which comprises two or more stimuli in known combinations it is possible to provide keyed association with previous training regimes.
