Abstract: Embodiments of the present invention allow more full characterization of a stenotic lesion by measuring both pressure drop across the stenotic lesion and the size of the vessel lumen adjacent the stenotic lesion, both with sensors delivered intravascularly to the stenotic lesion site. In preferred embodiments, the size (e.g., inner diameter, cross-sectional profile) of the vessel lumen adjacent the stenotic lesion can be measured via one or more intravascular ultrasound transducers. In preferred embodiments, the intravascular ultrasound transducer(s) can be delivered to the site of the stenotic lesion with the same delivery device that carries the pressure transducer(s).

Abstract: Methods of providing image-guided transendocardial injection of a therapeutic agent into a left ventricular wall of a heart. Some methods enable injections into heart tissue under visualization. The methods may include providing an endoventricular injection catheter having integrated echocardiographic capability. The endoventricular injection catheter may have an imaging core and an injection system carried on the elongated body with the imaging core. The method may include positioning the endoventricular injection catheter into the left ventricle of the heart, which inserts the imaging core into the heart. The method may also include transmitting ultrasonic energy via the imaging core, receiving reflected ultrasonic energy at the distal end, visualizing the left ventricular wall of the heart using the imaging core, identifying infarct regions of the left ventricle, and injecting a therapeutic agent into the visualized infarcted regions of the left ventricle using the injection system.

Abstract: An intravascular ultrasound imaging system comprises a catheter having an elongated body having a distal end and an imaging core arranged to be inserted into the elongated body. The imaging core is arranged to transmit ultrasonic energy pulses and to receive reflected ultrasonic energy pulses. The system further includes an imaging engine coupled to the imaging core and arranged to provide the imaging core with energy pulses to cause the imaging core to transmit the ultrasonic energy pulses. The energy pulses are arranged in repeated sequences and the energy pulses of each sequence have varying characteristics. The reflected pulses may be processed to provide a composite image of images resulting from each different characteristic.

Abstract: Systems and methods for image processing based on ultrasound data. The system may include an IVUS catheter configured to collect data vectors including ultrasound data and an imaging engine configured to process the ultrasound data of the data vectors. The imaging engine may receive the data vectors and divide the data vectors into different sets. The ultrasound data of each respective set may be averaged and then an envelope of each set may be detected. The envelopes of each set may then be averaged to generate an enhanced data vector which may be used to generate an image.

Abstract: Methods and systems are disclosed for detecting a region of disturbed blood flow within a blood-filled lumen and indicating the region of disturbed blood flow using a disturbed blood flow indicator. The region of disturbed blood flow can be detecting by processing a plurality of data vectors acquired by an imaging device. The plurality of data vectors can also be processed to generate an intravascular image. The intravascular image can be displayed to include the disturbed blood flow indicator at a region on the displayed image corresponding to a detected region of disturbed blood flow.
