Embodiments of the present disclosure are configured to assess the severity of a blockage in a vessel and, in particular, a stenosis in a blood vessel. In some particular embodiments, the devices, systems, and methods of the present disclosure are configured to provide FFR measurements over a length of a vessel of interest in a small, compact device that integrates with existing proximal and distal pressure measurement systems and does not require a separate power source.

Embodiments of the present disclosure are configured to assess the severity of a blockage in a vessel and, in particular, a stenosis in a blood vessel.

A system and method are disclosed for providing an equalized ultrasound echo signal for the rendering intravascular images. The system includes an ultrasound catheter including an ultrasound transducer probe. An intravascular ultrasound console receives an ultrasound echo signal corresponding to reflections of an ultrasound signal by backscatterers. An ultrasound echo signal time-gain compensation equalizer compensates the ultrasound echo signal according to sub-bands within a frequency response spectrum of the ultrasound echo signal. After applying selective amplifier gains on the sub-bands, the sub-band signals are combined to create an equalized ultrasound echo signal.

System and method for equalizing received intravascular ultrasound echo signals

A signal conditioning device is disclosed that interfaces a variety of sensor devices, such as guide wire-mounted pressure sensors, to physiology monitors. The signal conditioning device includes a processor for controlling sensor excitation and signal conditioning circuitry within the signal conditioning device. The processor also supplies signals to an output stage on the signal conditioning device representative of processed sensor signals received by a sensor interface of the signal conditioning device. Power for the signal conditioning device processor is supplied by an excitation signal received from a physiology monitor that drives the output stage. In addition, a temperature compensating current source provides an adjustment current to at least one of a pair of resistive sensor elements to compensate for differences between temperature change upon the pair of resistive sensor elements, thereby facilitating nullifying temperature effects upon the resistive sensor elements.
