Abstract: Systems and methods for receiving product data for products featured in a media asset are described. In some embodiments, the system includes control circuitry that receives from a server data for a plurality of products featured in a media asset. The control circuitry generates for display a list including the plurality of products. The control circuitry determines whether a product in the list is associated with a coupon and/or a preferred vendor. The control circuitry visually distinguishes the product from other products in the list in response to determining that the product is associated with a coupon and/or a preferred vendor.

Abstract: A trocar assembly includes an elongate trocar device and a surrounding cannula. The trocar device incorporates an electrosurgical cutting element which is used to make a guide hole for the cannula and thus enables the remainder of the trocar assembly to enlarge the puncture. An electronic control circuit senses the current flow to the cutting element and, when the trocar device breaks through the wall of the organ being cut, this circuit cuts off the connection to the associated electrosurgical generator. Further control circuitry prevents a surgeon from resuming electrosurgery until a predetermined time period has elapsed. Multiple trocars of different diameters are provided for the same assembly.

Abstract: A trocar assembly includes an elongate trocar device and a surrounding cannula. The trocar device incorporates an electrosurgical cutting element which is used to make a guide hole for the cannula and thus enables the remainder of the trocar assembly to enlarge the puncture. The cutting element comprises a bi-polar electrode assembly. An electronic control circuit senses the current flow to the cutting element and, when the trocar device breaks through the wall of the body cavity being cut into, this circuit cuts off the connection to the associated electrosurgical generator. Further control circuitry prevents a surgeon from resuming electrosurgery until a predetermined time period has elapsed. Multiple trocars of different diameters are provided for the same assembly.
