This is a braided tubular device used in the occlusion of various lumen or cavities in the body. In particular, it may be used to form an endovascular occlusion. Most desirably, it is braided of a majority of super-elastic alloy ribbons and therefore is both inherently non-stretching and most difficult to permanently deform. It may be deployed using an electrolytically severable joint. A radio-fre...

One side of the enlarged section (43) has a groove (36) of part circular cross-section which matc...

The invention relates to an agent specific for peripheral sensory afferents. The agent may inhibit the transmission of signals between a primary sensory afferent and a projection neuron by controlling the release of at least one neurotransmitter or neuromodulator from the primary sensory afferent. The agent may be used in or as a pharmaceutical for the treatment of pain, particularly chronic pain.
