    Abstract: An endovascular stent (12) for vascular vessels which can be used to occlude the vessel or which can be used to bridge damaged areas in the vessel. The endovascular stent comprising a stent that can be permanently expanded from a first diameter to a larger second diameter. The stent can be a helically wound wire stent, each wire comprising at least two strands. The two strands being twisted. The twisted strands securing fibers to form a fabric pile (18) extending outwardly from stent, and optionally extending inwardly into the stent. In a second embodiment, the stent is enclosed with a tubular-like expandable graft. The graft having an exterior fabric pile made up of individual fibers. In both embodiments, the fibers or the pile are optionally coated with a hydrophilic polymeric gel which expands upon being wetted.

    Abstract: Implant devices for filtering blood flowing through atrial appendage ostiums have elastic cover and anchoring substructures. The substructures may include reversibly folding tines or compressible wire braid structures. The devices are folded to fit in catheter tubes for delivery to the atrial appendages. The devices elastically expand to their natural sizes when they are expelled from the catheter tubes. Filter elements in the covers block emboli from escaping through the ostiums. The devices with tine substructures may have H-shaped cross sections. These devices seal the appendages by pinching an annular region of ostium tissue between the cover and the anchoring substructures. The shallow deployment depth of these H-shaped devices allows use of an universal device size for atrial appendages of varying lengths. The devices may include remotely activated fixtures for refolding the tines for device recovery or position adjustment.

    Abstract: Apparatus and method are disclosed by which a hollow distal end portion of a wire may be deposited at selected sites in body passageways. The apparatus includes an elongate wire (16) (solid or hollow) having a distal end section for detachment and delivery to a target location, the wire (16) also having a discontinuity (20) located rearwardly of the distal end section for rupturing when vibrational energy is applied to the wire (16). The discontinuities may take the form of cuts (38) formed in the wire (30), reduced diameter sections (49) in the wire (40), adhesive, welded or soldered couplings between the wire (50, 55, 60) and the distal end section, or the wire (200) transitioning from the wire (200) to a large mass (204) disposed on the distal end section. A catheter (304) is coupled to or surrounds the elongate wire (302) to deliver therapeutic liquid to a target body location. The apparatus includes a vibrational energy source (400) couplable to the proximal end of the wire (16) for selectively applying vibrational energy to the wire (16) to travel to the discontinuity (20) and cause detachment of the end section.

    Abstract: What is disclosed are medical devices comprising a rounded, thin-walled, expandable metal structure ("ballstent") and a flexible, elongated delivery device ("delivery catheter") and systems and methods of use for treating saccular vascular aneurysms with the medical devices. Ballstents comprised of gold, platinum, or silver that can be compressed, positioned in the lumen of an aneurysm, and expanded to conform to the shape of the aneurysm are disclosed. The external surface of ballstents can be configured to promote local thrombosis and to promote the growth of tissue into and around the wall of the ballstent in order to seal the aneurysm and fix the ballstent in place in the aneurysm. The wall of the ballstent can also be configured to release drugs or pharmacologically active molecules, such as those that promote thrombosis, cell proliferation, extracellular matrix deposition, and tissue growth.
