Abstract:
1. A method for making an elongated shaft for an intracorporal device, the method comprising: providing a proximal shaft portion having a proximal end and a distal end, attaching the distal end of the proximal shaft portion to a proximal end of a proximal connector; attaching a proximal end of an actuating shaft portion to a distal end of the proximal connector wherein the actuating shaft portion includes a shape memory material and is configured to shift from a first configuration to a second configuration; attaching a distal end of the actuating shaft portion to a proximal end of a distal connector; attaching a distal end of the distal connector to a proximal end of a distal shaft portion; attaching a proximal end of an actuating member to an outer surface of the proximal connector, attaching a distal end of the actuating member to an outer surface of the distal connector, the actuating member being free of a shape memory material and being configured to bias the actuating shaft portion into the first configuration; and attaching a thermal activator to the actuating shaft portion, thermal activator being configured to selectively activate a region of the actuating shaft portion.
