Abstract: A liquid embolic delivery system is provided for trapping an injected liquid embolic composition to prevent the liquid embolic from solidifying or otherwise passing outside of an embolization area. The delivery system includes a catheter for delivery of a liquid embolic composition and a containment member positioned at a distal end of the catheter which is shaped to trap the liquid embolic composition delivered through the lumen of the catheter. The containment member is formed as a brush, nest, sponge, swab, flexible sack, or other shape into and around which the liquid embolic composition is injected. The liquid embolic composition is trapped or meshes with the containment member during solidification containing the liquid embolic and preventing the embolic composition from passing into the blood stream.

Abstract: The present invention provides a process for producing an electroactive substrate. The process includes providing a substrate having an oxidant layer on a surface thereof, exposing the surface containing the oxidant layer to a vapour containing an aryl or heteroaryl monomer that is polymerizable to form an electroactive polymer, and polymerizing the aryl or heteroaryl monomer in the presence of a volatile Lewis base to form a polyaryl or polyheteroaryl electroactive polymer film on the surface of the substrate. The invention also provides electroactive substrates formed by the process.

Abstract: Systems methods and devices address and ameliorate intralumenal aneurysms by excluding the same through endograft by pass techniques. Percutaneuous emplacement, use of improved aortic-stent assemblies and shotgun neck framing facilitates placement of modular graft sections, for example, to treat abdominal aortic aneurysms.

Abstract: The present invention relates to a process for the preparation of graphene which can be used in the development of graphene paper or films, graphene-based composites and articles for nanoelectronics, nanocomposites, batteries, supercapacitors, hydrogen storage and bioapplications. This process comprises reducing purified exfoliated graphite oxide in the presence of a base.

Abstract: A temporary vascular filter system comprising a catheter and an elongate filter slideably carried near the distal end of said catheter. The vascular filter system can be inserted into a vessel percutaneously with the filter in a narrow-diameter “closed position” and expanded into a large diameter “open position” at the desired intravascular site. After deployment, the proximal portion of the catheter can be secured to the patient at the insertion site. While deployed, the filter component is capable of sliding along a portion of the catheter throughout a range of motion. The filter may have two filter meshes, which may have different degrees of porosity. The temporary vascular filter system can be left in the patient for hours or days and then collapsed into a withdrawal tube for removal from the patient.
