Abstract: A system may generate a prescription file including a plurality of data fields, assign the prescription file to a first queue for processing, provide a first queue GUI that includes the plurality of data fields grouped in a plurality of information modules and indicates an approval status of each information module, and receive user input editing one or more data fields. The system may assign the prescription file to a second queue, provide a second queue GUI that includes the plurality of information modules and indicates the approval status of each information module, and receive user input setting the approval status of each information module. If an information module is not approved, the system may reassign the prescription file to the first queue. If all information modules are approved, the system may assign the prescription file to a third queue for further processing.

Abstract: A torque control mechanism for a medical catheter, comprising a torque wire affixed to a tip of the catheter, and attached to a rotation control mechanism carried by a proximal end of the catheter. The torque wire has high torsional stiffness but longitudinal flexibility, so that rotation of the torque wire is efficiently transmitted to the catheter tip, but so that the torque wire may flex easily as the catheter is put into place adjacent a treatment site within a patient. The catheter tip includes a guide wire lumen for sliding over a conventional guide wire in emplacing the catheter, and rotation of the torque wire causes the catheter tip to rotate about an axis of the guide wire. However, when high friction is encountered by the catheter, rotation of the torque wire causes rotation of the catheter tip about a central axis of the catheter. This is assisted by the configuration of a preferred embodiment, wherein the catheter tip is rotatable separately from the catheter body.
