摘要: This is a device for bridging the necks of wide-necked or narrow-necked aneurysms in the vasculature. It is a device which may be used by itself to bridge the neck of an aneurysm or used to stabilize the presence of other vaso-occlusive devices such as helically wound coils in that aneurysm. The included vaso-occlusive devices may be delivered to the aneurysm in a variety of different ways, e.g., by a core wire which is linked to the coils by an electrolytically severable or mechanically detachable joint. The vaso-occlusive devices may also be simply pushed into the aneurysm. The aneurysm neck bridge may also be delivered in a variety of ways, but preferably is attached to an electrolytically severable joint for its deployment. The inventive neck bridge may contain one or two sections: a first or inner section to be placed within the aneurysm and an optional second or outer section suitably placed outside the aneurysm. The first section 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. The optional second or outer section has one or more array elements which are to be placed outside the aneurysm. The array elements typically extend from and are attached to an attachment area, often centrally located. The inventive device is at least partially formed of thin, usually metallic, sheets. After deployment of this retainer, the aneurysm may be partially filled with vaso-occlusive devices such as helically wound coils.

摘要: In one embodiment, a neck bridge for bridging the neck of an aneurysm includes a junction region, a number of radially extending array elements attached to the junction region, and a cover attached to one or both of the junction region and an array element. The array elements are configured to be positioned within the aneurysm after the neck bridge is deployed from a delivery device. In a second embodiment, the neck bridge includes a junction region and a braided or mesh-like structure secured to the junction region. The braided or mesh-like structure is made from an elastic material.

摘要: An apparatus for accessing a site within a body includes a cannula and an elongate member. The cannula has a proximal end, a distal end, and a lumen extending therebetween. The elongate member has a distal end configured for insertion into the lumen, wherein the distal end of the elongate member is attachable to and releasable from the distal end of the cannula. A method for accessing a site within a body includes inserting a distal end of an elongate member into a lumen of a cannula, detachably attaching the distal end of the elongate member to the cannula, and steering a distal end of the cannula to a desired site using the elongate member.

摘要: An improved guiding member for use within a body lumen having a unique combination of superelastic characteristics. The superelastic alloy material has a composition consisting of about 30% to about 52% (atomic) titanium, and about 38% to 52% nickel and may have one or more elements selected from the group consisting of iron, cobalt, platinum, palladium, vanadium, copper, zirconium, hafnium and niobium. The alloy material is subjected to thermomechanical processing which includes a final cold working of about 10 to about 75% and then a heat treatment at a temperature between about 450° and about 600° C. and preferably about 475° to about 550° C. Before the heat treatment the cold worked alloy material is preferably subjected to mechanical straightening. The alloy material is preferably subjected to stresses equal to about 5 to about 50% of the room temperature ultimate yield stress of the material during the thermal treatment. The guiding member using such improved material exhibits a stress-induced austenite-to-martensite phase transformation at an exceptionally high constant yield strength of over 90 ksi for solid members and over 70 ksi for tubular members with a broad recoverable strain of at least about 4% during the phase transformation. An essentially whip free product is obtained.
