Intravascular Devices Having Information Stored Thereon And/Or Wireless Communication Functionality, Including Associated Devices, Systems, And Methods

摘要

Intravascular devices, systems, and methods are disclosed. In some embodiments, the intravascular devices are guide-wires that include one or more sensing components and a sensor control module that stores information about the guide-wire. In some instances, the information about the guide-wire stored in the sensor control module is calibration information for a sensing component of the guide-wire. In some embodiments, the intravascular devices are guide-wires that include wireless communication functionality. In some instances, the guide-wires include one or more antennas adjacent a proximal portion of the guide-wire. In some instances, the guide-wires include passive radio frequency devices integrated into the guide-wire. Systems associated with such intravascular devices are disclosed. Methods of using such devices and systems are also disclosed.
