Inventor: BEHL ROBERT S
IPC: A61B18/28
Filed: 1990-09-12
Granted: 2002-04-23
Abstract: Hollow body organs, such as the gallbladder, may be ablated by introducing a substantially unheated thermally conductive medium to the interior of the organ. The thermally conductive medium is then heated to a temperature sufficient to necrose the enclothelial lining or mucous membrane of the organ. After the lining or membrane has necrosed, the interior of the organ will fibrose over time and the organ will eventually be resorbed by the body. A catheter useful in performing the ablation method comprises an elongate member having a heating element at its distal tip. The catheter will include at least one lumen for delivering the thermally conductive medium to the interior of the hollow body organ, and the heating means is used to raise the temperature of the thermally conductive medium after it has been delivered. Optionally, the catheter may include one or more inflatable balloons which facilitate sealing of the hollow body organ to inhibit leakage of the thermally conductive medium during the treatment process.

Granted: 1997-11-25
Abstract: The present invention relates to an improvement to a cryogenic process for the separation of air into its constituent components.  In the process, a distillation column system having at least two distillation columns, a high pressure distillation column and a low pressure column is used; these two distillation columns are in thermal communication with each other.  The low pressure column of the distillation column system operates at a pressure between 9 to 75 psig and a nitrogen product is produced from the top section thereof.  At least 50% of the air to the distillation column system is removed as this nitrogen product, which has a nitrogen concentration of at least 95% and is at a pressure of at least 9 psig.      The improvement to the process is a series of steps which allows for the production of liquid products from the cryogenic process in an efficient manner.  These steps are primarily the partial warming of the nitrogen product, its subsequent isentropic expansion and use of the inherent refrigeration of the expanded nitrogen.  These steps can be carried out in three ways.
