  • Patent number: 8945217
    Abstract: A medical device that includes a coating of a composite material that includes a polymeric material having a void structure and particulate ceragenin material (i.e., ceragenin particles) associated with the void structure. The average particle size of the ceragenin particles in the composite is in a range from 5 nm to 20 ?m, 50 nm to 10 ?m, 100 nm to 5 ?m, or 1 ?m to 10 ?m. The composite has a high loading of ceragenin particles (e.g., about 10% to about 25%, by weight). The composite has good polymer stability, the ability to release ceragenins from the ceragenin particles disposed in the composite over a sustained period of time at a characteristic elution rate, and the ability to kill large numbers of bacteria and other susceptible microbes over the sustained period of time.

  • Patent number: 8940043
    Abstract: A method of testing the performance of a collapsible prosthetic heart valve includes wrapping an aortic band around an outer surface of a portion of an aorta, fastening a first end portion of the aortic band to a second end portion of the aortic band, implanting a collapsible prosthetic heart valve in the aorta at an implantation site, and flowing a pressurized fluid through the aorta. The aortic band may be positioned near the sinotubular junction of the aorta. When installed around the aorta, the aortic band reinforces the portion of the aorta so as to be more resistant to radial expansion.

  • Patent number: 8920497
    Abstract: Methods and instruments for repairing a damaged acetabular labrum. The arc length of a portion of an acetabular rim proximal to the damaged (torn or broken) region of the acetabular labrum is measured, and a graft, such as a meniscal allograft or a gracilis autograft, is trimmed according to the measurement and secured in the damaged region of the acetabular labrum as a replacement.

  • Patent number: 8858632
    Abstract: Implants with hydrogel layers reinforced by three-dimensional fiber arrays can replace hyaline cartilage. Such implants should replace an entire cartilage segment, rather than creating a crevice around a plug, so these implants must be thin and flat, they must cover large areas, the tips of any tufts or stitches must not reach the hydrogel surface, and they must be flexible, for arthroscopic insertion. The use of computerized stitching machines to create such arrays enables a redesigned and modified test sample to be made with no delays, and no overhead or startup costs. This provides researchers with improved tools for making and testing implants that will need to go through extensive in vitro, animal, and human testing before they can be approved for sale and use. Fiber-reinforced hydrogels also can be secured to strong shape-memory rims, for securing anchoring to bones.

  • Patent number: 8858626
    Abstract: A two-optic accommodative lens system is disclosed. Two coupled lenses are located within the capsular bag to extend depth of focus and/or restore accommodation following extraction of a natural lens. The first lens comprises a spring-like structure attaching an optic to a ring-like support structure. The optic can be a monofocal or multifocal optical element having a positive or negative power. The first lens further comprises features designed to couple the ring-like structure to a second lens. The first lens can be located anteriorly within the capsular bag. The second lens is located posteriorly to the first lens within the capsular bag and can have an opposite or supplementary power to that of the first lens. The second lens can also be a monofocal or multifocal lens and comprises a plurality of haptics which can be used to size the lens system over a range of capsular bag sizes. The second lens further comprises features for coupling the second lens to the ring-like structure of the first lens.

  • Patent number: 8845751
    Abstract: An endoprosthesis component and a method for producing an endoprosthesis component is disclosed. The endoprosthesis component comprises a body predefining the shape of the endoprosthesis component. On surface portions with which the endoprosthesis component in the implanted state is in contact with human tissue, the body is covered with an outer layer which comprises a nitride, an oxynitride or an oxide based on a refractory metal and which contains silver and/or copper. An intermediate layer is arranged between the outer layer and the body in such a way that parts of the intermediate layer are accessible from the outside. The endoprosthesis component enables generation of a long-term antimicrobial action with the outer layer and, in addition, action on the surrounding tissue from the intermediate layer.

  • Patent number: 8845720
    Abstract: A prosthetic heart valve can include a valve frame having a wireform portion and a stent portion. The wireform and stent portions can be undetachably coupled together via a plurality of upright struts so as to form a one-piece prosthetic heart valve frame. Alternatively, a self-expanding wireform portion and a balloon-expandable stent portion can be coupled together via one or more leaflets and a subassembly having a flexible leaflet support stent and a sealing ring. The wireform portion can include cusps and commissures configured to support a plurality of leaflets. The prosthetic valve can be radially collapsible for minimally invasive and/or transcatheter delivery techniques. Disclosed embodiments can also provide flexion of the wireform portion (e.g., of the commissures) in response to physiologic pulsatile loading when the valve is implanted in a patient's native valve annulus. Methods of making and using prosthetic heart valves are also disclosed.
