A method and apparatus associated with the production of hydrocarbons is disclosed. The body has a medial face and a lateral face. Each data processing path may perform configurable operations in parallel on a same data. The followers are mounted rotatably on the dropouts and pivotally to at least one link mount being connected to the ground link. Also, the crossover point of the circumflex artery and coronary sinus may be determined and avoided when the device is deployed. The shell body defines a first offtake opening and a second offtake opening that extend in a circumferential direction about the longitudinal axis.
