A device receives trick play signals during a playing of content. The map information reading section reads map information. A lightguide element is permanently connected to the handle and has a light input face, which is successively moved past the light sources when the handle rotates, and a light output face, which is assigned to a photosensitive element. Such structural features can include a set of concentric rings having an approximately non-linear cross section, and protrude into the surface of the dielectric plate. The catheter wall thickness in the deflecting segment of the guide catheter is about 1 French or less, and includes a slotted deflection tube, and this construction allows a very tight turning radius which in turn enables guide catheter access to regions of the vasculature that are otherwise inaccessible. , a balanced valve, which normally blocks medication flow to the outlet port and opens only in response to a pump induced unbalancing force.
