An example medical device includes a support member having a proximal end region and a distal end region and a sensing member having a proximal end region and a distal end region, the distal end region of the sensing member coupled to the distal end region of the support member. The medical device also includes one or more ultrasound sensors disposed along the sensing member and a support shaft having a first end coupled to the sensing member and a second end coupled to the support member. Additionally, the sensing member is configured to shift from a first configuration in which the sensing member is adjacent to the support member to a second configuration in which at least a portion of the sensing member extends away from the support member. ## Claims ### Claim 1 A medical device, comprising: a support shaft having a proximal end region and a distal end region; a sensing member having a proximal end region and a distal end region, the distal end region of the sensing member coupled to the distal end region of the support shaft; one or more ultrasound sensors disposed along the sensing member;
