Abstract: This invention is an apparatus for the formation of occlusions in spaces in the human body, occluding such as thrombi in arteries, veins, aneurysms, vascular malformations and arteriovenous fistulas. In particular, it deals with a one piece assembly having an improved electrolytically erodable link to an occlusive member and further having an incorporated return electrode in the assembly. The occlusion-forming member is introduced to and is intended to remain at the desired occlusion site. The invention also relates to the joint itself. The invention further includes a method for introduction and electrolytic separation of the device.

Abstract: Disclosed herein catheters, assemblies comprising a single-lumen catheter having one or more sources of electro-magnetic radiation disposed within the wall of said catheter. Methods of using these catheters and assemblies are also provided.

Abstract: Compositions comprising devices for retrieving objects from a subject, for example the subject's vasculature, are described. Also described are methods of making and using these devices.

Abstract: This is a surgical device usually delivered through an intravascular catheter. It may be used in several ways. It may, for instance, be used to open a clear passageway adjacent thrombus to allow both blood and medication to bypass the clot. It may be used to pierce and to remove thrombus. These thrombus are often found in tortuous vasculature. The device includes several sections. The device has a core element, typically a core wire. Placed around the distal end of the core element is a collapsible but preferably self expanding proximal cage assembly and a distal filter, preferably a self-expanding cage assembly or other filter component. The various portions of those components are preferably radio-opaque. The proximal end of the proximal cage is typically is affixed to an actuator in such a way as to allow expansion of the cage after deployment.

Abstract: A surgical device for opening a passageway adjacent a thrombus to allow both blood and medication to bypass a clot. The surgical device may also be used to pierce and remove a thrombus. The device includes a core element or wire having an expanding proximal cage assembly and a distal filter or expanding cage assembly placed around the core wire. Components of the device are preferably radio-opaque. The proximal end of the proximal cage may be affixed to an actuator to allow expansion of the cage after deployment. The proximal cage assembly may be used for collecting emboli or for displacing emboli to allow blood flow to resume, either with or without concurrent clot-dissolving drug treatment. The distal section is placed distally of the thrombus to collect portions of the thrombus which may loosen during the treatment or removal procedure.
