  • Patent number: 6936055
    Abstract: This is a device for bridging the neck of either a wide-necked or narrow-necked aneurysm in the vasculature. In general, it is a device used to stabilize the presence of vaso-occlusive devices (such as helically wound coils) in the aneurysm. The device preferably is delivered by a core wire which terminates in an electrolytically severable joint. The core wire will often be insulated. The retainer assembly itself is also attached to the electrolytic joint and 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. After deployment of this retainer, the aneurysm is at least partially filled with a vaso-occlusive device such as helically wound coils.

  • Patent number: 5603991
    Abstract: This invention is in the general field of surgical instruments and, in particular, catheters. Specifically, it relates to procedures for coating the interior surfaces of surgical devices with a cross-linkable lubricious polymer, preferably one which is hydrophilic. These catheters may be variously used in cardiovascular and endovascular procedures to deliver diagnostic, therapeutic, or vaso-occlusive agents or devices to a target site within a human or animal body and to catheters used to guide other catheters to a particular site in that body. The interior of the catheters are coated using the noted procedure in such a way that the interior is exceptionally slippery and very durable.
