A method of authorizing a limited use intravascular device can include determining if the intravascular device is in communication with a clinical system； determining if the intravascular device is authorized for clinical operation without providing the clinical system access to intravascular device data stored on the intravascular device； and providing an authorization signal to the clinical system. An intravascular device can include a flexible elongate member including a sensing component at a distal portion and a connector at a proximal portion, the connector including: a memory component configured to store a parameter value； a processing component； and a charge storage component configured to power the memory component and/or the processing component； wherein the processing component is configured to determine if the flexible elongate member is authorized for clinical operation using the parameter value without providing the parameter value to a clinical system.
