Patent ID: 8652050

Claim:
An intravascular imaging device, comprising: an elongate member having a proximal portion and a distal portion; an actuator mechanism disposed adjacent the distal portion of the elongate member, the actuator mechanism comprising a first anchor, a second anchor, at least one movable element, a deformable component, and a first Shape Memory Alloy (“SMA”) actuator, and an imaging element connected to the at least one movable element; wherein the first anchor is connected to a first side of the at least one moveable element by the first SMA actuator and the second anchor is connected to a second side of the at least one movable element by the deformable component; wherein the first and second anchors are secured relative to the elongate member; wherein a longitudinal axis of the actuator mechanism extending between the first anchor and the second anchor is substantially parallel to the longitudinal axis of the elongate member; wherein the first SMA actuator has an activated state and a deactivated state; and wherein the at least one movable element and the imaging element move in a first direction relative to the elongate member upon activation of the first SMA actuator.
