Abstract: Medical device balloons are formed from a tubular parison by a process or apparatus which establishes a controlled location (initiation zone) on the parison where radial expansion is initiated. Initiation within the initiation zone is achieved by heating the parison in that location to a higher temperature than the remainder of the parison for at least a portion of the blowing time. A variety of apparatus configurations are provided, some of which allow for the size and location of the initiation zone to be readily reconfigured. Balloons can also be modified, post-blowing, using heating apparatus and methods described.

Abstract: An apparatus for tacking a multi-lumen tubular assembly together comprises a laser, an optical member and a placement tray for retaining the tubular assembly. A portion of the optical member defines a window that is substantially transparent to laser energy emitted from the laser. The window has a substantially concave shaped surface. The placement tray and the window surface define a processing area for positioning at least a portion of the tubular assembly. The processing area receives the laser energy that is emitted from the laser and passed through the window of the optical member. The tubular assembly is defined by an outer tubular member disposed about at least a portion of at least one inner tubular member. The laser energy transmitted into the processing area is transmitted substantially through the outer tubular member and is substantially absorbed by at least one region of the least one inner tubular member.

Abstract: A memory module includes a memory module controller to be coupled to a system memory controller by a system memory bus and a plurality of memory devices coupled to the memory module controller, where signaling between the memory module controller and one or more of the memory devices is independent of signal loading or operating voltage of the system memory bus.

Abstract: Methods and apparatus for a memory system using a new memory module architecture are disclosed. In one embodiment, the memory module has two ranks of memory devices, each rank connected to a corresponding one of two 64-bit-wide data registers. The data registers connect to two 64-bit-wide ports of a 128:64 multiplexer/demultiplexer, and a 64-bit-wide data buffer connects to the opposite port of the multiplexer/demultiplexer. A controller synchronizes the operation of the data registers, the multiplexer/demultiplexer, and the data buffer. In an operating environment, the data buffer connects to a memory bus. When a data access is performed, both ranks exchange data signaling with their corresponding data registers during a single data access. At the buffer, the memory bus data transfer occurs in two consecutive clock cycles, one cycle for each rank. This allows the memory bus transfer rate to double for the same memory bus width and memory device speed.
