| 20090234277 | DELIVERY SYSTEM - A covering for delivering a substance or material to a surgical site is provided. The covering, with substance provided therein, may be referred to as a delivery system. Generally, the covering may be a single or multi-compartment structure capable of at least partially retaining a substance provided therein until the covering is placed at a surgical site. Upon placement, the covering may facilitate transfer of the substance or surrounding materials. For example, the substance may be released (actively or passively) to the surgical site. The covering may participate in, control, or otherwise adjust, the release of the substance. | 09-17-2009 |
| 20100082072 | BONE ANCHORS FOR ORTHOPEDIC APPLICATIONS - Bone anchors and related methods for their use are described. The inventive anchor is suitable for placement in bone and for use in orthopedic surgery and dentistry. The bone anchor can be made from a bone/polymer or bone substitute/polymer composite, and can provide a firm and secure base for attaching a fastening device. The bone anchor can be used in various orthopedic and dental procedures including spinal surgery, where normal, cancellous, cortical, diseased or osteoporotic bone is present. The bone anchor can be resorbed and/or replaced with native bone tissue over a period of time. In certain embodiments, the bone anchor is made malleable or flowable and formed in situ or in vivo. | 04-01-2010 |

| 20100042204 | Stent Coating For Eluting Medication - A vascular stent comprising a drug-eluting outer layer of a porous sputtered columnar metal having each column capped with a biocompatible carbon-containing material is described. This is done by placing the stent over a close-fitting mandrel and rotating the assembly in a sputter flux. The result is a coating that is evenly distributed over the outward-facing side of the stent's wire mesh while preventing the sputtered columnar coating from reaching the inward facing side where a smooth hemocompatible surface is required. The stent is then removed from the mandrel, exposing all surfaces, and finally coated with a layer of carbon such as amorphous carbon or diamond-like carbon. The carbonaceous coating enhances biocompatibility without preventing elutriation of a therapeutic drug provided in the porosity formed between the columnar structures. The result is a stent that is adapted to both the hemodynamic and the immune response requirements of its vascular environment. | 02-18-2010 |

| 20100189879 | Method For Providing An Implantable Electrical Lead Wire - Implantable electrical lead wires, such as cobalt-chromium-molybdenum alloy wires, are coated with a metal, ceramic, or carbon to a thickness of about 100 nm or less to provide a non-reactive interface to polyurethane sheathing materials. Preferred is sputter coating an amorphous carbon intermediate the alloy wire and the polyurethane sheath. | 07-29-2010 |
