    摘要： A vaso-occlusive implant has a primary helical-coil shape that defines a primary axis and a three-dimensional secondary shape. The secondary shape includes a substantially helical section and a second section having a plurality of non-overlapping loops or loop sections. Each loop defines a plane that is oriented at an angle from about 30-150 degrees relative to a plane defined by an immediately preceding or immediately succeeding loop along the primary axis. The coil sections or loops can be generally circular loops or other smooth shapes.

    摘要： Described herein are devices, systems and methods for determining if a nerve is nearby a device or a region of a device. In general, a device for determining if a nerve is nearby a device includes an elongate body having an outer surface with one or more bipole pairs arranged on the outer surface. Bipole pairs may also be referred to as tight bipoles. The bipole pairs may be arranged as a bipole network, and may include a cathode and an anode that are spaced relatively close together to form a limited broadcast field. In general, the broadcast filed is a controlled or “tight” broadcast field that extends from the bipole pair(s). Methods of using these devices and system are also described.

    摘要： A method and system for inserting an implant, such as vaso-occlusive device, an embolic containment device, or a stent into a vascular space to a vascular site in a body utilizing a lumen-reducing catheter. The method and system can be used to treat aneurysm, tumors and other vascular malformations. A guide is inserted into the vascular space. First and second catheters are inserted into the vascular space along the guide. The first or delivery catheter defines a first cavity, and the second or lumen-reducing catheter defines a second, smaller cavity. The second catheter is inserted within the first catheter. In one embodiment, an implant is advanced together with the first and second catheters to a vascular site. In an alternative embodiment, after the first and second catheters are positioned, the guide and the second catheter are removed from the first cavity, and an implant is inserted through the first cavity. With these configurations, radial movement of the guide is restricted to the smaller, second cavity rather than the larger, first cavity.

    摘要： This device is an apparatus for endovascular occlusion through the formation of thrombi in arteries, veins, aneurysms, vascular malformations, and arteriovenous fistulas. In particular, the device includes multiple vaso-occlusive members connected by electrolytically disintegratible links. Each link connects to the vaso-occlusive member by electrically insulative and conductive joints on opposite ends of the link. The vaso-occlusive members are delivered through a delivery catheter having on its distal end an electrode for electrical contact with the vaso-occlusive member. Upon application of an electrical current through electrode to the vaso-occlusive member and its conductive joint to electrolytically disintegratible link, the link disintegrates, selectively detaching the desired number of vaso-occlusive members into the target thrombus formation site.
