Abstract: A medical device optical connector lead for coupling with a guidewire including optical fiber is described herein. The connector can include or use a housing defining an aperture, an optical receptacle disposed within the housing, the optical receptacle configured to receive an exposed optical fiber end of the guidewire extending through the aperture, and a chuck configured to clamp around the guidewire. The chuck can be slidable within the housing between a first chuck position wherein the chuck is positioned closer to the optical receptacle than to the aperture and a second chuck position wherein the chuck is positioned closer to the aperture than to the optical receptacle. An actuator can laterally move the chuck between the first position and the second position and concurrently tighten or loosen the chuck.

Abstract: An inflatable balloon cuff associated with a tracheal tube may be adapted to reduce the passage of mucosal secretions into the lungs. A cuff as provided may include a sealing composition that plugs or seals any folds in the inflated cuff that may act as leak paths for mucosal secretions. Further, tracheal tube kits are provided for application and/or removal of the sealing composition.
