Abstract: A method for treating an occlusion comprises positioning a catheter at a treatment site in a patient's vasculature. A blockage is located at the treatment site. The method further comprises performing a medical treatment at the treatment site. The medical treatment is configured to reduce the blockage. The method further comprises making a plurality of measurements at the treatment site.

Abstract: This is an implantable vaso-occlusive coil which is implanted using minimally invasive surgical techniques. It is a complex, helically wound coil made up of a primary helically wound coil which is then wound into a specific secondary shape. The secondary shape is itself a series of helical turns. At least a portion of the turns in the secondary shape form a cylindrical region and adjacent that region on at least one end is a conical region which tapers from a diameter approximating that of the central cylindrical region to a smaller diameter. The device is desirably self-forming upon exit from the distal end of a delivery catheter. Also, the conical tipped vaso-occlusive device may also utilize thrombus-enhancing filamentary material.

Abstract: A device for occluding a space within the body, and particularly,the device usefle as a vaso-occlusive device. In partiular, the device typically comprises a metallic core or core member, and two polymeric conjuncts, often polymeric members, of differing thrombogenicity. Typically, the core member comprises a metallic helically-wound coil; the first polymeric member and second polymeric member are fibrous materials woven into a braid. The device may be placed at the desired site within a mammal to facilitate the formation of an occlusion. The device promotes the formation of scar tissue, healing tissue, or neocapillaries in vascular occlusions made by the device.

Abstract: This is a device for bridging the neck of either a wide-necked or narrow-necked aneurysm as may be found in the vasculature. It may be used to stabilize the placement of vaso-occlusive devices such as helically wound coils in the aneurysm or may be used to, at least partially, close the aneurysm neck. The vaso-occlusive devices, commonly helically wound coils, are delivered by a core wire which is linked to the coils by an electrolytically severable joint. The core wire will often be insulated. The retainer assembly itself is also attached to another delivery device, such as a core wire, and desirably is severed from the core or delivery wire by the use of another electrolytically severable joint. The inventive neck bridge typically has a number of array elements which are intended to be resident within the aneurysm after the device is deployed from the distal end of a catheter. Central to this invention is the use of array elements having differing flexibility or constituent members of the array elements, e.

Abstract: This is an implantable vasoocclusive device. It is constructed of a primary helically wound coil, which primary coil is further wound into secondary shapes which are at least partially substantially conical. Other portions of the secondary shape may have sections of constant diameter or of other conical shapes. The primary coil may be made in such a way that it has regions of differing flexibility. Fibrous materials may be placed on the coils in tufted, streamer, or woven configurations so to increase the thrombogenicity of the overall assembled device.
