1. An intravascular device comprising:
- a ring-shaped transducer array located at a distal end of the intravascular device, wherein the ring-shaped transducer array is configured to image a tissue;
a therapy lumen located at the distal end of the intravascular device, wherein the therapy lumen passes through the ring-shaped transducer array and terminates in a therapy port that is configured to deliver a therapy to a tissue; and
a sensor located distal to the therapy port at a distal-most tip of the distal end of the intravascular device, wherein the sensor is separate from the ring-shaped transducer array and is configured to measure blood flow in an environment associated with the tissue.

Abstract
Using the disclosed intravascular devices it is possible to image tissues, deliver therapy, and evaluate the tissue after the therapy is delivered. One embodiment is a catheter configured to provide ultrasound imaging, drug delivery, and Doppler flow analysis. The devices can use ultrasound imaging as well as optical coherence tomography (OCT).

14. An intravascular device for simultaneous imaging, monitoring and therapy of tissue located within a patient, the intravascular device comprising:
-
a ring-shaped ultrasonic transducer array located at a distal end of the intravascular device, wherein the ring-shaped ultrasonic transducer array is configured to image the tissue; a therapy lumen in fluid communication with a proximal end and the distal end of the intravascular device, wherein the therapy lumen passes through the ring-shaped ultrasonic transducer array and terminates in a therapy port at the distal end of the intravascular device to apply a therapy to the tissue; and a blood flow sensor located distal to the therapy port at a distal-most tip of the distal end of the intravascular device, wherein the sensor is separate from the ring-shaped ultrasonic transducer array and is configured to measure blood flow in an environment associated with the tissue. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)
