  • Patent number: 10925714
    Abstract: The techniques of this disclosure generally relate to a variable permeability layered prosthesis including an impermeable outer layer and a permeable inner layer. The impermeable outer layer is well suited to seal a dissection opening of a dissection. The permeable inner layer allows fluid to enter into a dead space between the impermeable outer layer and the permeable inner layer. The fluid in the dead space coagulates in the dead space providing a media for tissue growth into the prosthesis. The ability of tissue to integrate into the prosthesis provides biological fixation of the prosthesis in vessels and prevents endoleaks and migration of the prosthesis.

  • Patent number: 10893947
    Abstract: A femoral augment, or set of augments, for use with a knee joint prosthesis, where the femoral augment includes a main body portion, an aperture formed within the main body portion and extending in a generally distal/proximal direction, and a pair of legs extending outwardly from said main body portion in a generally posterior direction. In the preferred embodiment, the aperture is configured to receive a stem extension implant, and to allow it to pass through. Additionally, the legs of the femoral augment are preferably configured to be seated proximal of a proximal side of a pair of condylar portions of a femoral component of a knee joint prosthesis. The present invention is intended for situations in which the distal portion of the femur is defective, and it provides a method and devices that allow for preservation of healthy peripheral bone, while still providing the necessary augmentation to the distal portion of the femur.

  • Patent number: 10888411
    Abstract: Disclosed herein is an intravascular stent for being implanted into blood vessels and a method for manufacturing the same. The intravascular stent is woven by at least one weaving wire, and the stent is in a tubular structure. The at least one wire has an even number of free ends, and the free ends of the at least one wire are aligned and jointed together with each other, which have cutting portions. The cutting portions of the two free ends that are aligned and jointed with each other match each other to make the two free ends be engaged into a joint portion with a diameter identical to that of the wire. The intravascular stent has seamless connection, and the distribution of radial force and axial force of the free ends is uniform, leading to convenience for laser welding. Moreover, the intravascular stent has great flexibility, excellent operability and perfect appearance.

  • Patent number: 10856965
    Abstract: A needle lattice is used to form openings within a graft material to selectively enhance permeability of a prosthesis for tissue integration therein. The needle lattice may be disposed on, for example, a surface of a roller or press. The needle lattice precisely places openings in any pattern and location, and on any textile that forms the graft material. The needle lattice can be heated to fuse the surrounding material of the openings of the textile to prevent movement of the textiles and to prevent collapse of the openings. All parameters of the openings, including varying density, patterns, and size of each opening, can be controlled, allowing for the opportunity to selectively enhance and optimize the permeability of the graft material in a vessel. The needle lattice can quickly form multiple openings within a graft material, allowing for quick manufacturing of the prosthesis.

  • Patent number: 10849667
    Abstract: The invention relates to a biodegradable, magnesium-containing bone screw for implanting into a patient body for use in medical applications, such as, orthopedic, craniofacial and cardiovascular surgery. The bone screw has a head, shaft and tip. The thickness of the head is greater than the thickness of conventional bone screws. The shaft includes both a non-threaded and a threaded portion. The tip is non-threaded and pointed, such as, conical in shape. The composition of the bone screws provide for improved biodegradability and biocompatibility, and the features of the structure of the bone screws facilitate guidance and placement during implantation as well as reduce the potential for mechanical failures.

  • Patent number: 10799375
    Abstract: An aortic bare stent and an aortic dissection stent are disclosed. The aortic bare stent is in a tubular net structure, with multiple support stents in circles and arranged along an axial direction. Two adjacent support stents are connected by a connector stent. The connector stent is made of a hyper-elastic material. A flexural rigidity of the connector stent is less than that of the support stent. The support stent is made of a single-strand hyper-elastic nickel titanium wire or formed by cutting a nickel titanium tubing. The connector stent is made of a multi-strand composite wire. The multi-strand composite wire is formed by twisting or weaving multiple strands of filaments, and each strand of filament is independently of a nickel titanium material.
