摘要： A medical electrical lead is disclosed that is adapted for placement in the coronary sinus, or a branch vein thereof. The lead includes a first and second pace/sense electrode. A selection mechanism is provided to select either the first or the second electrode for use as a cathode, with the other electrode being selected as the anode. According to another aspect of the invention, a high-voltage coil electrode may be provided between the first and second electrodes. The coil electrode may be electrically coupled to the anode to increase the shadow area of the coil electrode.

摘要： A magneto optic or optical disk drive comprises a laser source for providing laser beam, and a lens or compound lens for focussing the laser onto a currently inserted recording disk with specific overcoat thickness. In one embodiment, the lens is a compound lens that can focus aberration-free spots on different types of disk media having recording layers located under overcoats of different thicknesses. When a specific disk is inserted, only one spot in focussed onto the current recording layer. Furthermore, if the disk spins rapidly, it can wobble. The lens or compound lens comprises different regions where the focal length may vary slightly and continuously or discretely. Because of this, as the disk wobbles, the lens can nonetheless continue to focus laser light onto a small spot on the recording media, providing increased depth of focus in the vicinity of the currently inserted recording media. Furthermore, the increased depth of focus will also remedy problems related to the change in focal length of the lens with changes in wavelength of the laser source. Because some of these changes in wavelength occur abruptly, this is also a case in which the limited performance of the auto-focus tracking system would be overly burdened.
摘要翻译：磁光盘或光盘驱动器包括用于提供激光束的激光源和用于将激光聚焦到具有特定外涂层厚度的当前插入的记录盘上的透镜或复合透镜。在一个实施例中，透镜是可以将像差自由点聚焦在具有位于不同厚度的外涂层下的记录层的不同类型的盘介质上的复合透镜。当插入特定盘时，只有一个点集中在当前记录层上。此外，如果磁盘快速旋转，则可能会摆动。透镜或复合透镜包括不同的区域，其中焦距可以稍微和连续地或离散地变化。正因为如此，随着磁盘的摆动，透镜可以继续将激光聚焦到记录介质上的一个小点上，从而在当前插入的记录介质附近提供增加的焦点深度。此外，增加的焦深也将补救与激光源的波长变化相关的透镜焦距变化的问题。因为这些波长的一些变化突然发生，所以这也是自动对焦跟踪系统的有限性能过度负担的情况。

摘要： An improved system and method for deploying medical electrical leads is disclosed. The system includes a guiding device such as a guidewire used to navigate the vascular system of a body. The guiding device includes a fixation member that can be deployed to maintain the guiding device at a desired location within the vascular system. The fixation member may be an inflatable device such as a balloon, or alternatively, may be an expandable device constructed of flexible fibers that has both an expanded and a contracted state. The system may further include a coupling member located adjacent to the guiding device. The coupling member may be a rail extending distally from a proximal end of the guiding device to a point proximal the fixation member. In an alternative embodiment of the invention, the coupling member is a channel included in the body of the guiding device adapted to slidably engage an electrode assembly. The coupling member is adapted to allow the electrode assembly to be slid to the distal end of the coupling member and deployed at a predetermined implant site. In one embodiment of the invention, the coupling member is movable with respect to the guiding device. This allows the coupling member to be re-positioned to multiple implant sites to deploy more than one electrode while the fixation mechanism remains stationary within a patient's vascular system. According to yet another aspect of the invention, the guiding device includes a lumen to delivery fluoro visible medium.

摘要： A method for forming a novel head used in magneto-optic or optical disks comprises the steps of forming a diffractive lens on one side of a glass substrate and forming air bearing surface rails on a second side of said glass substrate. The glass substrate is then cut into separate heads. In this way, many magneto-optic or optical heads can be formed simultaneously without incurring the expense of bonding lenses onto a slider. In one embodiment, coils are deposited on the substrate to generate a magnetic field during magneto-optic write operations. In another embodiment, a glass wafer having diffractive lenses formed thereon is bonded to a silicon spacer structure. The glass lenses are used to define a waveguide structure on a transparent layer on the bottom of the silicon spacer

摘要： A method of treating cardiac conduction defects and/or congestive heart disease. The method involves identifying the branch arteries that feed blood to the specialized cardiac conduction cells of the heart and/or to any ischemic regions of the heart. Any occlusions in these arteries are then opened using conventional PTCA devices and procedures which, prior to the present invention, have not been used to treat occlusions in the branch arteries that supply blood to the heart.
