1. A device comprising:
- a catheter member defining a first guidewire lumen sized to advance over a first guidewire, the catheter member having a longitudinal axis defined along a length of the catheter member; and
a guidewire housing member defining a second guidewire lumen sized to advance over a second guidewire and being axially fixed relative to the catheter member, the guidewire housing member having a distal end portion, the distal end portion including at least one activatable material configured to move the distal end portion between at least a first directional arrangement and a second directional arrangement upon application of a stimulus, the first directional arrangement providing a parallel arrangement of the second guidewire relative to the longitudinal axis, and the second directional arrangement providing an angled arrangement of the second guidewire relative to the longitudinal axis.

Abstract
A medical device having at least one static state, at least one activated state, and at least one active region including electroactive polymer (EAP) capable of fine electro-activated movements. The EAP movements include bending components for proper alignment, rotating components for proper fittings, making components more rigid or flexible, and increasing and decreasing the volume of components. The fine movements allow for highly versatile and adaptable medical devices.
