Abstract: A device includes a handle, an expandable structure including a plurality of splines extending from a proximal hub to a distal hub, a first electrode on a first spline of the plurality of splines, an outer tube extending from the handle to the proximal hub, and a shaft extending through the outer tube from the handle to the distal hub. The expandable structure has a collapsed state and a self-expanded state. The handle is configured to retract the shaft. Retracting the shaft may expand the expandable structure outward of the self-expanded state.

Abstract: Some embodiments of a medical device anchor system include an anchor device that receives a medical instrument (such as a catheter or the like) and secures the instrument in place relative to a skin penetration point. In some circumstances, the anchor device may allow the anchor device to be used after medical instrument is already in place without the need for a second penetration point for the anchor device.

Abstract: A write cache operation builder for use in building a write operation for writing data from a cache to a disk drive in a computer system is disclosed. The write cache operation builder is built from a CMS of a DASD. It converts the CMS entries of the CMS into a FIFO entry and scans the FIFO entry in order to calculate a write operation comprising the largest number of sectors of data. The write cache operation builder may be implemented via hardware or software.
