Coding techniques for a video image compression system involve improving an image quality of a sequence of two or more bi-directionally predicted intermediate frames, where each of the frames includes multiple pixels. The mounting structure comprises a case, one pair of sliding slots and at least one recess. Such simultaneous inspection processing and transmission may be implemented using two ownership bits for the packet, one to indicate \u201cownership to process\u201d and one to indicate \u201cownership to send,\u201d instead of the single ownership bit that is used in conventional systems. The two slots into which the marbles fall may equate to two dice being rolled in certain traditional craps games. The catheter includes a guidewire configured to carry a balloon and deploy directly in a branch leg without traversing acute bends. A method for producing the same is also provided.
