    摘要： A catheter assembly includes a main catheter branch and a side catheter branch. The main catheter branch includes a main balloon, a side balloon and a side inflation member. The side inflation member intersects the side balloon at a location on the side balloon that is offset laterally from a central line passing from a distal most point on the side balloon to a proximal most point on the side balloon. The side balloon is configured to extend radially outward relative to the main balloon when the side balloon is inflated. The side catheter branch can be centrally aligned with the side balloon central line and be positioned laterally adjacent to the side inflation lumen.

    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.

    摘要： Multi-filar, open and closed coil, tubular medical stents that are introduced to a site in a body lumen and released to expand at the site to provide a passageway through the stent lumen are disclosed. Each stent filar is a coil wound in substantially the same pitch through the majority of its length between the ends thereof. The coils are attached together at least at one coil end to form an end of the stent and wound in an interleaved manner such that the adjacent coils are substantially evenly spaced apart or in close contact in the released state and do not cross over one another. In one open coil stent embodiment, both ends of each coil are attached in respective first and second common attachment junctions, and the resulting coils have relatively even predetermined spacing between adjacent coil turns through the majority of the length of the stent between the first and last coil turns when the stent is released. Preferably, the first and second stent ends are formed by attaching the coil ends in common, and the stent ends are squared by decreasing the pitch of the first coil turn extending from the stent end such that the spacing of the stent end from the adjacent coil is reduced from the predetermined spacing. Additionally, multi-filar closed coil stent embodiments are disclosed having only one end of each coil attached in common and adjacent coil turns in substantial mutual and overlying contact in the restrained state during implantation and non-overlying contact in the released state. Preferably each common attachment junction of attached coil ends and each free coil end is formed into an enlarged stent end in at least one dimension for ease of attachment to and release from a stent delivery catheter. The common attachment junction can be snared or grasped by a stent retrieval system and retracted from the body lumen.
