  • Publication number: 20170266018
    Abstract: An implant or endoprosthesis suitable to be implanted in human or animal tissue includes two (or more than two) parts to be joined in situ. Each one of the parts includes a joining location, the two joining locations facing each other when the device parts are positioned for being joined together, wherein one of the joining locations includes a material which is liquefiable by mechanical vibration and the other one of the joining locations includes a material which is not liquefiable by mechanical vibration and a structure (e.g. undercut cavities or protrusions) suitable for forming a positive fit connection with the liquefiable material. The joining process is effected by pressing the two device parts against each other and by applying ultrasonic vibration to one of the device parts when the two parts are positioned relative to each other such that the two joining locations are in contact with each other.

  • Patent number: 9757237
    Abstract: The fusion device for fusing a synovial joint of a human or animal patient, in particular a human facet joint, finger joint or toe joint, includes two pin-shaped anchorage portions and arranged therebetween a stabilization portion. The anchorage portions include a thermoplastic material which is liquefiable by mechanical vibration. The stabilization portion preferably has a surface which is equipped for enhancing osseointegration. The anchorage portions have a greater thickness and a greater depth than the stabilization portion. Then the fusion device is pushed between the articular surfaces and mechanical vibration, in particular ultrasonic vibration, is applied to the proximal face of the fusion device. Thereby the liquefiable material is liquefied where in contact with the bone tissue and penetrates into the bone tissue, where after re-solidification it constitutes a positive fit connection between the fusion device and the bone tissue.

  • Publication number: 20160317248
    Abstract: A dental appliance removal tool is provided with one or more booster tubes each having a pressure-actuated expandable distal portion or cushion which, when inserted between a gum line and an implant-supported denture and connected to a supply of pressured fluid, expands radially to increase the circumference of the cushion and apply pressure to the gum line and denture to loosen or release the denture from an implant or the like. The tool may have an actuation mechanism such as a lever arm which applies pressure to a fluid chamber in communication with the booster tube, causing the cushion to expand, or a manually operated fluid pump or other pressurized fluid supply may be connected to the booster tube or multiple booster tubes to expand the cushion or cushions.

  • Patent number: 9387023
    Abstract: A system and method of angularly stable fixation of an implant on a bone includes the steps of making at least one hole in the bone by means of a bone drill. An implant is placed on the bone in a desired position and joining the implant with the bone, such that the implant is prevented from rotation about its attachment point. A system is provided for use in the above described method. The system comprises a bone drill, an implant and a sonotrode for angularly stable fixation of the implant on the bone. The system can further comprise a joining element to join the implant with the bone.

  • Publication number: 20160074085
    Abstract: A perforated sheath is anchored in a tissue opening with the aid of a tool, wherein the anchorage is achieved with the aid of mechanical vibration and a material which is liquefiable by the vibration. The tool includes a vibrating element and a counter element. Distal portions of both elements are introduced into the sheath to be in contact with each other at an interface. The vibrating element is connected to a vibration source and the vibrating element and the counter element are held against each other for effecting liquefaction of the liquefiable material at the interface. Under the effect of the force applied to the vibrating and counter element for holding them against each other, the liquefied material flows from the interface through the sheath perforation and penetrates the tissue.

  • Publication number: 20160074171
    Abstract: A spine stabilization device having an interbody spacer shaped to be inserted between a vertebral body of an upper vertebra and a vertebral body of a lower vertebra. The device further includes a fixation device to be inserted after placement of the interbody spacer, the fixation device having a support portion securing the interbody spacer against escaping from between the vertebral bodies into a ventral direction. The support portion rests against a portion of an anterior surface of the interbody spacer, and includes an anchor. The anchor has an anchoring material portion that is inserted, in a liquid state, into cancellous bone tissue of at least one of the vertebral bodies of the upper and lower vertebra, to thereby infiltrate the cancellous bone tissue, and to harden thereafter so as to fix the support portion to the vertebral body.

  • Publication number: 20150045838
    Abstract: A punching device for preparing a recess in a bone has a punching tool usable for such a punching device. An implant usable with the punching tool is provided and a method for preparing a recess in a bone are disclosed. The punching device comprises an ultrasonic sonotrode and a punching tool which is fixable to the sonotrode at its proximal extremity. At its distal extremity, the punching tool has a thin-walled portion having a non-rotational symmetric cross-section. By ultrasonic vibration of the punching tool, the thin-walled portion can be forced into a bone thereby preparing a recess of which is not rotationally symmetric. Subsequently, an implant can be held in such recess. Due to its lack of rotational symmetry, the implant may absorb rotational forces around its longitudinal axis.
