  • Publication number: 20240193233
    Abstract: Methods, systems, and storage media for managing digital entitlements are disclosed. Exemplary implementations may: determine at least one digital entitlement; generate a digital backpack; select a third party platform; generate an application program interface (API) call associated with the at least one digital entitlement to a third party application; and store the at least one entitlement in the digital backpack.

  • Patent number: 9113858
    Abstract: Devices and systems are described for treating intraluminal locations such as in a patient's lung. The device has an elongated shaft with an inner lumen, preferably defined by an inner tubular member, formed of heat resistant polymeric materials such as polyimide. The device also has an outer surface formed of heat resistant material. High temperature vapor is directed through the inner lumen into the intraluminal location to treat tissue at and distal to the location. An enlarged or enlargeable member, such as a balloon, is provided on a distal portion of the shaft to prevent proximal flow of the high temperature vapor upon discharge from the device.

  • Patent number: 8585645
    Abstract: Methods are describe for treating intraluminal locations such as in a patient's lung. The device is a catheter which has an elongated shaft with an inner lumen, preferably defined by an inner tubular member, formed of heat resistant polymeric materials such as polyimide and high temperature vapor is directed through the inner lumen into the intraluminal location to treat tissue at and/or distal to the location. The outer surface of the catheter is also formed of heat resistant material. An enlarged or enlargeable member, such as a balloon, is provided on a distal portion of the catheter shaft to prevent proximal flow of the high temperature vapor upon discharge from the catheter.

  • Publication number: 20060161233
    Abstract: This invention relates to the treatment of a patient's lung, for example, a lung exhibiting chronic obstructive pulmonary disease (COPD) and in particular to methods and devices for affecting lung volume reduction, preferably for achieving acute or immediate lung volume reduction following treatment. The lung volume reduction is effected by delivering a condensable vapor at a temperature above body temperature to the desired regions of the patient's lung to damage tissue therein. Blood flow and air flow to the damaged tissue region is essentially terminated, rendering the target region non-functional. Alternative energy sources may be used to effect the thermal damage to the lung tissue.

  • Publication number: 20050227130
    Abstract: An improved fuel processor for fuel cells is provided whereby the startup time of the processor is less than sixty seconds and can be as low as 30 seconds, if not less. A rapid startup time is achieved by either igniting or allowing a small mixture of air and fuel to react over and warm up the catalyst of an autothermal reformer (ATR). The ATR then produces combustible gases to be subsequently oxidized on and simultaneously warm up water-gas shift zone catalysts. After normal operating temperature has been achieved, the proportion of air included with the fuel is greatly diminished.
