Abstract
An apparatus includes an intraluminal device. The intraluminal device includes a flexible elongate shaft that is positioned within a body lumen of a patient and a pullwire disposed within the flexible elongate shaft that transitions a distal portion of the flexible elongate shaft between a first configuration and a second configuration. The intraluminal device also includes a handle coupled to a proximal portion of the flexible elongate shaft. The handle includes an actuation mechanism connected to the pullwire. The actuation mechanism transitions the distal portion between the first configuration and the second configuration, maintains the distal portion in the first configuration or in the second configuration without continuous input by a user.
