A sack is formed at a distal end of the cooling catheter. The sack is in fluid communication with distal ends of the inlet channel and the outlet channel such that the sack is continually flushed with the cooling fluid as the cooling fluid flows into and out of the cooling catheter. The sack, when filled, takes the shape and size of the ventricular cavity filling the ventricular cavity in which it is positioned. The method further includes cooling the cooling catheter and the ventricular cavity through the closed flow of the cooling fluid through the cooling catheter. | 02-03-2011 |
| 20110054258 | FOAM PORT INTRODUCER - The present disclosure relates to devices for introducing a port within a body cavity.

| 20100251622 | SLIDER GATE - Standard ground track slide gates roll along a piece of inverted angle iron fastened to the ground the entire length of travel from the fully open to the fully closed position. Typically this is accomplished by a stationary post set on either side of the gate with rollers attached to where the top horizontal frame member passes. With this arrangement of rollers, a situation exists in which there is a heavy steel gate panel moving past two stationary posts. This can be a potentially dangerous situation since the chance of entrapment is a distinct possibility. The present invention describes a method of assembly by someone not necessarily skilled in the art and is intended to solve the problems associated with these safety issues as well as provide the possibility of a more decorative sliding gate | 10-07-2010 |

| 20080293473 | Wagering Game with Character Learning - Wagering game terminal and method of operating same are disclosed where the player characters or avatars learn from the experiences of previous games. Thus, the player characters or avatars in effect remember the paths they have taken and/or the choices they have selected previously. This learning or remembrance may occur across multiple games and may be manifested by visual and/or audio reminders, including removal of the previously taken paths/choices. Other indicators such as audio or text messages may also be used. The player characters or avatars may also refuse or be reluctant to repeat a particular path/choice. In this way, the player may retain the benefits of his earlier efforts, thereby increasing player excitement and enjoyment. | 11-27-2008 |
| 20100130276 | Wagering Game With Asset Trading - Method and system are disclosed for operating a wagering game terminal where players are allowed to transfer game assets that they may have accumulated to other players. The game assets may be transferred as part of an on-line auction won by one of the other players, as a gift to a preselected player, or as part of a trade with a preselected player. Neither the transferring player nor the receiving player is required to be present at a wagering game terminal at the time of the transfer. The transfer may be an anonymous transfer or it may be an identity-based transfer. For identity-based transfers, a predefined list of selected players may be used to facilitate the transfers. | 05-27-2010 |
