  • Publication number: 20140155946
    Abstract: A method of changing a bone angle includes creating an osteotomy between a first portion and a second portion of a tibia of a patient; creating a cavity in the tibia by removing bone material along an axis extending in a substantially longitudinal direction from a first point at the tibial plateau to a second point; placing a non-invasively adjustable implant into the cavity, the non-invasively adjustable implant comprising an adjustable actuator having an outer housing and an inner shaft, telescopically disposed in the outer housing, and a driving element configured to be remotely operable to telescopically displace the inner shaft in relation to the outer housing; coupling one of the outer housing or the inner shaft to the first portion of the tibia; coupling the other of the outer housing or the inner shaft to the second portion of the tibia; and remotely operating the driving element to telescopically displace the inner shaft in relation to the outer housing, thus changing an angle between the first porti

  • Patent number: 8690932
    Abstract: A collapsible bone screw for healing bone fragments across a bone fracture includes an externally threaded inner screw member and an externally threaded outer screw member. The inner screw member is initially screwed into an inner bone portion. An unthreaded portion of the outer screw member is movably joined to the inner screw member. The outer screw member is screwed until it gains purchase in an outer bone portion. As impaction occurs over time, the collapsible bone screw apparatus may shorten in length as the two screw members slide, telescope or otherwise axially move toward each other to shorten the overall length, thereby preventing any portion of the screw apparatus from protruding out of the bone. A bone screw kit of multiple inner and outer screw members are provided as well as a method of surgically fastening bone fragments.

  • Publication number: 20100280526
    Abstract: A medical device with an articulating shaft assembly includes at least one slat member which has a cross section that allows it to be substantially flexible in a first plane and relatively stiff in the plane perpendicular to the first plane. A bendable section located at the working end of the device includes at least a portion of one or more slat members, such that the bendable section will articulate in the first plane in response to tensive and/or compressive forces applied to the bendable section. The device also includes a shaft section which is coupled to and supports the bendable section, and at least one control mechanism arranged to cause the tensive and/or compressive forces needed to articulate the bendable section to be applied to the bendable section.

  • Publication number: 20090254102
    Abstract: A delivery mechanism for delivering tissue holding implants through tissues to be held in approximation includes a shaft having a tip at its distal end, and which is loaded with one or more implants. A wire channel which contains a driving wire is also located within the shaft. When the mechanism is actuated, the driving wire exhibits a proportional longitudinal displacement in the wire channel, such that the wire engages an implant, conveys it along the shaft's longitudinal axis towards the tip, and forces it through the tip. The implants are oriented such that they lie along or nearly along the shaft's longitudinal axis when being conveyed along the axis. The mechanism may optionally include an opposing jaw arranged such that, when actuated, the distal end of the jaw is moved towards the tip, such that tissues placed between the jaw and tip are pinned between them.
