    摘要: 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.

    摘要: The occlusion balloon catheter includes an elongated tubular catheter body having a fluid lumen for inflation of an occlusion balloon detachably mounted to the catheter body by a tubular shape memory collar. The occlusion balloon includes a valve for sealing the occlusion balloon when it is inflated, and the collar of shape memory material clamps onto a stem of the valve. The shape memory collar can be heated by a fiber optic pusher member threaded through the catheter body to cause the collar to assume an enlarged configuration disconnecting the occlusion balloon. A method of detaching the occlusion balloon from the occlusion balloon catheter involves the steps of placing the occlusion balloon catheter within a guiding catheter, and placing the guiding catheter within the vasculature so that the distal opening of the guiding catheter extends into an aneurysm or other deformation to be treated. The fiber optic pusher is then used to expel the device into the aneurysm.

    摘要: This is an implantable vaso-occlusive device. It is typically a vaso-occlusive coil comprising a primary helically wound coil which may then be wound into a secondary shape. Central to the invention is the use of a stretch-resisting member extending through the lumen formed, which stretch-resisting member is fixedly attached, directly or indirectly, to the coil in at least two locations. The stretch-resisting member is preferably somewhat loose within the interior of the lumen so to prevent the coil from collapsing, binding, and therefore stiffening during passage of turns through the human body. The coil should bend easily. In some variations of the invention, the stretch-resisting member may be formed into coil tips at the ends of the coil using simple equipment such as soldering irons or the like. The tips are typically of the same diameter as is the coil body itself. This stretch-resisting member is for the primary purpose of preventing stretching of the coil during movement of that coil, e.g., by retrieval or repositioning after deployment. The device may have a self-forming secondary shape made from a pre-formed primary linear helically wound coil, although it need not have the secondary form. Desirably, the coil is extremely flexible and is controllaby released using a severable or mechanical joint such as an electrolytically detachable joint. External fibers may be attached to the device and affixed to the pre-formed linear member to increase thrombogenicity. The extremely flexible variation of the invention may be hydraulically delivered through the lumen of a catheter and is so flexible that it may be retrievably delivered therethrough a flow-directed catheter. The vaso-occlusive member may be also be covered with a fibrous braid. The device is typically introduced into the body through a catheter. The device is passed axially through the catheter sheath and assumes its secondary form upon exiting the catheter.

    摘要: The vasoocclusive apparatus can be used in a method of interventional therapy and vascular surgery by inserting the apparatus into a portion of a vasculature, for treatment of a body vessel such as an aneurysm in conjunction with a secondary vasoocclusive device to be placed within the vessel. The vasoocclusive apparatus includes a plurality of strut members connected together at a central hub that extend from a collapsed position to an expanded configuration to cross the neck of the aneurysm, dividing the neck into smaller openings, allowing the deployment of the secondary vasoocclusive device within the aneurysm but preventing migration of the secondary vasoocclusive device from the aneurysm. The strut members can be made from a twisted cable of strands of a superelastic material, such as a shape memory nickel titanium alloy, with at least one radiopaque strand. A shape memory collar is provided for detachably mounting the vasoocclusive apparatus to a pusher member and for detaching the vasoocclusive apparatus for deployment when a desired placement within an aneurysm to be treated and out of a parent vessel is achieved.
