Abstract: Various aspects of the present disclosure are directed toward implantable medical devices, systems, and methods for cardiac assistance.

Abstract: Collecting, validating, managing, and sharing data, for example healthcare and patient data, may include using a networked portable device. A forms-based system and process (referred to in some embodiments as DirectForms™) may allow clinical staff to efficiently collect and validate data on portable devices. In accordance with an embodiment, the system combines a portable computing device, validation of data, network connectivity, and an opportunity for shared effort among users via industry-standard (for example HL7 compliant) or customized interfaces. A server-based utility may route forms and HL7-compliant data transaction exports. Interfaces may provide for merging data into appropriate patient records. Some systems may be used in an ambulatory care setting. Various aspects may provide for improved clinical assessment, effective patient management, cost savings, and the ability to provide a more efficient billing process.

Abstract: A sealing system for a plug-type unloader includes a bonnet having a guide bore with a stem reciprocably mounted within the guide bore. One end of the stem is affixed to a plug and the other end of the stem is connected to an actuator. A bellows member is positioned around the stem within the plug. The bellows member includes an expandable and contractible bellows having one end attached to the bonnet and the other end attached to the stem. Static seals are provided between one end of the bellows and the bonnet and the other end of the bellows and the stem. The bellows between the ends allows the bellows member to expand and contract as the stem reciprocates within the unloader. No dynamic seals are required. The plug of an unbalanced unloader includes a bore slidingly receiving an adapter around the bellows member to protect the bellows member from the pressure pulsations around the plug.

Abstract: The edges of the port exits of a poppet valve seat member are each provided with a 30 degree chamfer and a counter-bore immediately upstream of the chamfer to significantly reduce exit flow losses. The depth/width of the counter-bore is between about 2:1 and about 3:1.
