Abstract
Devices and methods for passing optical radiation into and out of a body lumen may include a rotatable ferrule for use in an optical guidewire and methods for using a rotatable ferrule. The rotatable ferrule may be either rotatably captured by and free to rotate within a guidewire, or may rotate upon release from a releasable, mechanically stable friction-fit engagement with a guidewire. Sterile interfaces for readily connecting and disconnecting an optical guidewire with and from other optical instrumentation while maintaining the sterility of the guidewire, and methods for using a sterile interface device are disclosed. Interface devices can be used to provide either direct or indirect optical and mechanical connection between an optical guidewire and peripheral instrumentation.
