    摘要： A radially expandable stent comprising a plurality of spaced band-like elements and intersecting links is disclosed. The band-like elements have a generally serpentine configuration to provide continuous waves of generally sinusoidal character to each band-like element. The waves are characterized by a plurality of peaks and troughs taking a generally longitudinal direction along the cylinder such that the waves in the band-like elements open as the stent is expanded from a first diameter to a second diameter. The intersecting links are substantially U-shaped and terminate in first and second shanks. The first shank of a link emanates from a region between a peak and trough on a band-like element and the second shank of the link emanates from a region between a peak and trough on an adjacent band-like element.

    摘要翻译： 公开了一种包括多个间隔开的带状元件和相交连接件的可径向扩张的支架。 带状元件具有大致蛇形结构，以向每个带状元件提供大致正弦曲线的连续波。 波的特征在于沿着圆柱体大致纵向方向的多个峰和谷，使得当支架从第一直径扩展到第二直径时，带状元件中的波浪打开。 交叉连接件基本上为U形并终止在第一和第二柄部中。 链节的第一柄从带状元件上的峰和谷之间的区域发出，并且链节的第二柄从相邻带状元件上的峰和谷之间的区域发出。

    摘要： Improved stent configurations exhibiting limited recoil, resistance to compression and improved longitudinal flexibility are disclosed. The stent comprised of a plurality of annular elements aligned to form a cylindrical stent body. The annular elements are comprised of a plurality of open, generally boomerang-shaped segments interconnected top-to-bottom around each of the annular elements. Adjacent annular elements are interconnected by interconnecting element.

    摘要： Some embodiments of an electrical stimulation system employ wireless electrode assemblies to provide pacing therapy, defibrillation therapy, or other stimulation therapy. In certain embodiments, the wireless electrode assemblies may include a guide wire channel so that each electrode assembly can be advanced over a guide wire instrument through the endocardium. For example, a distal tip portion of a guide wire instrument can penetrate through the endocardium and into the myocardial wall of a heart chamber, and the electrode assembly may then be advanced over the guide wire and into the heart chamber wall. In such circumstances, the guide wire instrument (and other portions of the delivery system) can be retracted from the heart chamber wall, thereby leaving the electrode assembly embedded in the heart tissue.
