Abstract: A catheter device for crossing occlusions includes an elongate body, a central lumen extending within the elongate body from the proximal end to the distal end, a rotatable tip at the distal end of the elongate body, and an OCT imaging sensor. The rotatable tip is configured to rotate relative to the elongate body. The OCT imaging sensor includes an optical fiber coupled with the rotatable tip and configured to rotate therewith. A distal end of the elongate body includes one or more markers configured to occlude the OCT imaging sensor as it rotates. A fixed jog in the elongate body proximal to the distal end of the catheter positions the distal end of the catheter at an angle relative to the region of the catheter proximal to the fixed jog and is aligned with the one or more markers on the elongate body.

Abstract: In the manufacture of sweets from a continuous rope of toffee or like confectionery material and the wrapping thereof in suitable wrapping material, it is customary to ensure that the feed of the rope is interfered with in the event of any interference with the supply of wrapping material. The present invention provides such interference by substantially instantaneously removing driving contact between the rope and the rope-driving surface, thus substantially preventing unwrapped sweets from coming into contact with the wrapping elements.

Abstract: A sweet-forming and wrapping machine includes feed rollers for feeding a rope of candy to a cutting mechanism and mechanism for transferring sweets cut from the leading end of the rope to a wrapping wheel, a wrapper being fed into the path of transfer of each sweet to the wrapping wheel. A detector operates in response to failure of the wrapper feed to stop the machine and also to divert the rope instantaneously out of its normal path of travel towards the cutting mechanism.
