    摘要: A catheter assembly for deployment in a vessel includes a catheter shaft extending from a proximal end portion to a distal end portion. A balloon is operatively coupled to the distal end portion of the catheter shaft. At least one cutting member is coupled to the catheter assembly. As the balloon is inflated, the cutting member is moved to a position to cut a portion of the vessel.

    摘要: A medical device comprises a catheter having a catheter shaft and a medical balloon positioned thereon, as well as a rotatable assembly disposed about the balloon. The balloon has a pre-expansion state and an expanded state. The rotatable assembly comprises a sheath, wherein the sheath is disposed about the balloon in both the pre-expansion state and in the expanded state. The sheath is rotatable about the balloon in the pre-expansion state. The sheath comprises an inner layer and an outer layer, the inner layer is in rotatable contact with the balloon and the outer layer is disposed about the inner layer. The inner layer is at least partially constructed of at least one material having a durometer value greater than that of the outer layer.

    摘要: One or more multi-level NAND flash cells are operated so as to store only single-level data, and these operations achieve an increased level of charge separation between the data states of the single-level operation by requiring a write to both the upper and lower pages, even though only one bit of data is being stored. That is, the second write operation increases the difference in floating gate charge between the erased state and the programmed state of the first write operation without changing the data in the flash memory cell. In one embodiment, a controller instructs the flash memory to perform two write operations for storing a single bit of data in an MLC flash cell. In another embodiment, the flash memory recognizes that a single write operation is directed a high reliability memory area and internally generates the required plurality of programming steps to place at least a predetermined amount of charge on the specified floating gate.
