Abstract: A humidification system can include a heater base, a humidification chamber, and a breathing circuit. A cartridge can be removably coupled to the heater base. The cartridge can include various sensors, probes, sensor wire connectors, heater wire connectors, and/or other features. The cartridge can include features configured to mate with corresponding features on the humidification chamber and the heater base. The cartridge includes a memory, such as an EEPROM, or other suitable storage device. When the cartridge is installed on the heater base, the memory is electrically connected to a processor and/or memory of the heater base. Various models of cartridges can be produced for use with different humidification chambers, breathing circuits, and/or therapies. A connector can be configured to couple an inspiratory conduit to an outlet port of the humidification chamber. The connector can provide a pneumatic connection to the outlet port and an electrical connection to the cartridge.

Abstract: The invention pertains to a method and apparatus for enhancing the depth of the acetabulum to improve the containment of the femoral head, and the concepts of the invention are employed to correct an unstable hip joint, particularly as occurs with children. A synthetic extracapsular curvalinear prosthesis is affixed to the ilium by fasteners and the prosthesis includes a concave surface corresponding to the configuration of the acetabular socket wherein the prosthesis increases the depth of the acetabulum without disturbing the existing anatomy.
