A surgical tool includes a member, a guide wire received within the member by a friction fit, and a guide wire pusher for application of a force to the guide wire to overcome the friction fit and advance the guide wire relative to the member. The device can simultaneously detect and quantitate multiple analytes in a sample. The system and the method enable a user to control media rendering from multiple storage devices andor multiple servers connected to the home network using the mobile device. The system uses a reservation entity, to which a thin device may subscribe, which reserves space for the thin device without allocating that space before it is need to service an IO request. A response may be interrupted to make another menu selection, or to repeat the current response.
