  • Fistula grafts having a deflectable graft body portion
    Patent number: 8535349
    Abstract: This invention provides, in certain aspects, unique devices and methods for treating fistulae. In one embodiment, an inventive device includes an elongate graft body having a proximal end and a distal end. The graft body is configurable to a first condition and a second condition, the second condition including the distal end deflected laterally relative to its position in the first condition of the body. The device also includes a tether, which is connected to the graft body, and is configured to traverse proximally along the body. The tether is manipulable to convert the graft body from the first condition to the second condition. Such a device may also include one or more additional tethers connected to the graft body. For instance, a second tether can be configured to extend distally from the distal end of the graft body, and may be effective in pulling the graft body along a fistula tract.

  • COATINGS FOR MODIFYING MONOFILAMENT AND MULTI-FILAMENTS SELF-RETAINING SUTURES
    Publication number: 20130072974
    Abstract: The present invention provides that coatings applied to natural, synthetic and recombinant expressed polymer filaments can be used to modify the properties of monofilament and multifilament self-retaining sutures. In an embodiment of the invention, the coating enables the suture to be easily inserted into tissue, whereupon the extended interaction of the coating and the tissue increase the ability of the tissue retainers to hold the suture in the tissue. In an embodiment of the present invention, the coated polymers have a melting point in the range from between approximately 40° C. to approximately 180° C. while retaining tensile strength. In an embodiment of the invention, the increased strength is due in part to the tissue specific reaction generated by the suture coating.

  • MEDICAL SUTURE HAVING MICRO COGS ON SURFACE AND METHOD OF MANUFACTURING THE SAME
    Publication number: 20130072971
    Abstract: Provided are a medical suture having micro cogs on a surface thereof and a method of manufacturing the medical suture. The method of manufacturing a medical suture includes steps of: producing a suture preform where micro cogs are formed on a surface thereof by heating and pressing a raw material of a suture for surgery in an overflow mould in a heat-press solid-phase forming method; and producing a suture with twist maintained by applying a tensile force and a rotational force to the suture preform in a vacuum state where a specific temperature condition is maintained.

  • Looped Suture
    Publication number: 20130066368
    Abstract: A method of forming a loop in a thread is provided. The method includes the steps of providing a loop forming system including, a base for securely retaining a thread to be formed and a welding assembly for forming a loop in the thread, contacting at least a portion of the thread with a super-critical fluid and securing the previously immersed portion of the thread to the base such that a first section of the previously immersed portion is maintained adjacent to a second section of the previously immersed portion. The method further includes the steps of approximating the welding assembly and the base towards each other, and approximating the welding assembly and base away from each other. Also provided is a medical device formed from the method.

  • IMPLANTS FOR CREATING CONNECTIONS TO TISSUE PARTS, IN PARTICULAR TO SKELETAL PARTS, AS WELL AS DEVICE AND METHOD FOR IMPLANTATION THEREOF
    Publication number: 20130060265
    Abstract: Implants for forming a positive connection with human or animal parts include a material, such as thermoplastics and thixotropic materials, that can be liquefied by means of mechanical energy. The implants are brought into contact with the tissue part, are subjected to the action of ultrasonic energy while being pressed against the tissue part. The liquefiable material liquefies and is pressed into openings or surface asperities of the tissue part so that, once solidified, the implant is positively joined thereto. The implantation involves the use of an implantation device that includes a generator, an oscillating element, and a resonator. The generator causes the oscillating element to mechanically oscillate, and the element transmits the oscillations to the resonator. The resonator is used to press the implant against the tissue part to transmit oscillations to the implant.
