摘要： An implantable medical lead comprising one or more tines configured to extend and/or retract from a lead body. The implantable medical lead includes a torque member within the implantable medical lead and configured to rotate a drive shaft within the implantable medical lead. The drive shaft is threadably engaged with an interior surface of the implantable medical lead and configured to convert the rotation into a lateral translation of the drive shaft. The one or more tines are configured such that the lateral translation of the torque member laterally translates the one or more tines. The one or more tines are each electrically connected to a conductor extending through a lumen of the implantable medical lead and electrically isolated from each other.

摘要： Treatment of an aneurysm or other vascular defect can be facilitated or enhanced by a galvanic cell formed by an implantable medical device configured to be implanted at or within the aneurysm or other vascular defect. The implantable medical device can include a primary structure including an anodic metal and a cathodic metal. The anodic metal and the cathodic metal each form a fraction of a total surface area of the primary structure. A galvanic cell formed by the anodic metal and the cathodic metal is configured to induce a galvanic voltage within blood for a duration of time to promote thrombosis. The thickness of the anodic metal can be less than or equal to 5 μm, for example, to provide galvanic activity for between 5 and 30 minutes.

摘要： A fistula catheter that can prevent separating from the fistula by an inner balloon even if an outer balloon collapses by configuring an internal fixed part with an inner side balloon and an outer side balloon is disclosed. The fistula catheter A has an external fixed part, a supply tube with a primary cavity and a secondary cavity, and an internal fixed part on the tip end side outer periphery of the supply tube, expandable by a compound liquid that includes barium sulfate and distilled water supplied though the secondary cavity. The internal fixed part can be an inner balloon and an outer balloon that communicate with the secondary cavity through filler ports on the peripheral surface of the supply tube. A filter on the filler port can enable distilled water in the compound liquid to be filled into the outer balloon from the secondary cavity through the filter, and the compound liquid can be filled into the inner balloon.

摘要： A vascular remodeling device is provided. The device includes an anchor portion, sized for deployment in a blood vessel, that is radially expandable from a collapsed state to an expanded state. The device also includes a distal portion that is sized for deployment in a blood vessel. The distal portion is radially expandable from a collapsed state to an expanded state and, in some embodiments, has a distal face that is sufficiently occlusive in the distal- to-proximal direction to perform a therapeutic blocking function at an aneurysm. Some embodiments have an intermediate portion that connects a distal end of the anchor portion and a proximal end of the distal portion, and in some embodiments, the anchor portion and distal portion are able to pivot relative to each other at or near the intermediate portion.
