Abstract
Multi-mode capacitive micromachined ultrasound transducer (CMUT) and associated devices systems, and methods are provided. In an embodiment, an intravascular device includes a flexible elongate member having a proximal portion, a distal portion, and a first sensor assembly disposed at the distal portion of the flexible elongate member. The first sensor assembly comprising comprises a first array of capacitive micromachined ultrasonic transducers (CMUTs). The first sensor assembly comprises at least two of a pressure sensor, a flow sensor, or an imaging sensor. In some embodiments, the intravascular device further includes a second sensor assembly comprising a second array of CMUTs.
Claims16
An intravascular device, comprising:
- a flexible elongate member having a proximal portion and a distal portion;
- and
- a first array of capacitive micromachined ultrasonic transducers (CMUTs) disposed at the distal portion of the flexible elongate member,
- wherein the first array of CMUTs is configured to obtain diagnostic data only such that the first array of CMUTs is not used for treatment,
- wherein the first array of CMUTs is operable as at least two different sensor types selected from the group consisting of a pressure sensor, a flow sensor, and an imaging sensor such that:
- at a first time, an individual CMUT of the first array of CMUTs obtains the diagnostic data corresponding to a first intravascular data type;
- and
- at a different, second time, the same individual CMUT obtains the diagnostic data corresponding to a different, second intravascular data type,
- wherein the first intravascular data type comprises a modality selected from the group consisting of intravascular pressure measurement, intravascular flow measurement, and intravascular imaging,
- wherein the different, second intravascular data type comprises a modality different from the first intravascular type,
- wherein the different modality is selected from the group consisting of the intravascular pressure measurement, the intravascular flow measurement, and the intravascular imaging, and
- wherein the intravascular pressure measurement and the intravascular flow measurement are different than the intravascular imaging such that the intravascular pressure measurement and the intravascular flow measurement do not obtain an image.

A method of obtaining intravascular data, the method comprising:
- controlling, using a computing device, an array of CMUTs positioned at a distal portion of an intravascular device inserted into vasculature of a patient to obtain diagnostic data only such that the array of CMUTs is not used for treatment, wherein the controlling comprises:
- controlling an individual capacitive micromachined ultrasonic transducer (CMUT) of the array of CMUTs to obtain, at a first time, the diagnostic data corresponding to a first intravascular data type;
- and
- controlling the same individual CMUT to obtain, at a different, second time, the diagnostic data corresponding to a different, second intravascular data type, wherein the first intravascular data type comprises a modality selected from the group consisting of intravascular pressure measurement, intravascular flow measurement, and intravascular imaging, and wherein the different, second intravascular data type comprises a modality different from the first intravascular type, wherein the different modality is selected from the group consisting of the intravascular pressure measurement, the intravascular flow measurement, and the intravascular imaging;
- processing, at the computing device, at least the diagnostic data corresponding to the first intravascular data type and the diagnostic data corresponding to the second intravascular data type;
- and
- providing, from the computing device to a display in communication with the computing device, graphical representations of at least the processed diagnostic data corresponding to the first intravascular data type and the processed diagnostic data corresponding to the second intravascular data type for display,
- wherein the array of CMUTs is operable as at least two different sensor types selected from the group consisting of a pressure sensor, a flow sensor, and an imaging sensor, and
- wherein the intravascular pressure measurement and the intravascular flow measurement are different than the intravascular imaging such that the intravascular pressure measurement and the intravascular flow measurement do not obtain an image.
