Abstract: Methods, apparatus, and systems for intravascular analysis combine at least three analytical modalities. In one implementation, intravascular ultrasound, optical coherence tomography, and near infrared spectroscopy are combined to enable detection of multiple, different abnormalities in the arterial morphology during a single intravascular procedure.

Abstract: A local protractive message on hold device, which contacts and interacts with a server, in order to receive from the server the audio programming and to install and alter the audio programming on the message on hold device. The device may interact with said server by any sort of electronic communication medium capable of transmitting digitized information as binary code or as binary code embedded in a text format based on ASCII. The local protractive device identifies itself to the server, then either the local device or the server checks specific areas within the storage system of the server to see if there are programming changes available for the local device. If there are no changes available in the storage system of the server; local device terminates its link to said server and then resumes normal operation.
