  • Patent number: 9974574
    Abstract: Disclosed is a cervical plate having a polyester staple fiber laminated within a polycarbonate urethane. The polyurethane provides a flexible, high resilience structure with a Dacron® material providing a flexible skeleton. The result is a cervical plate that is flexible but provides the necessary rigidity. An inflatable balloon can be used to mimic the properties of the natural disc by maintaining the intervertebral disc space through a full range of natural motion.

  • Patent number: 9078761
    Abstract: The present disclosure describes embodiments for treating a defect in a tissue, the tissue having internal and external surfaces. A device includes a first portion for positioning at one of the internal and external surfaces for applying a treatment force to the defect. In addition, the device has a second portion for applying a counter-force, where the second portion is operable to be positioned so that the counter-force is applied on the other of the internal and external surfaces, away from the defect so as to substantially avoid application of force at the defect. Furthermore, the device includes a coupling member for connecting the inner and outer portions. Methods of using the device are described, for example in an intervertebral disc having a herniation.

  • Patent number: 8951254
    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 (1) and arranged therebetween a stabilization portion (2). The anchorage portions (1) include a thermoplastic material which is liquefiable by mechanical vibration. The stabilization portion (2) preferably has a surface which is equipped for enhancing osseointegration. The anchorage portions (1) have a greater thickness (T1) and a greater depth (D) than the stabilization portion (2). Then the fusion device is pushed between the articular surfaces and mechanical vibration, in particular ultrasonic vibration, is applied to the proximal face (4) 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.

  • Patent number: 8858565
    Abstract: A positioning and installation tool for a fixation implant is inserted through a single, simple drill hole and positioned in place. The device controls the degree to which the implant is deployed and prevents accidental disengagement of the device from the implant before deployment has completed. The device also guides the components of the implant involved in active tendon compression at the aperture of the bone tunnel. The implant is deployed simply by rotating a knob, thereby creating an anchor point of high stiffness and fixation strength. When deployment has completed, the inserter is disengaged from the affixed implant by simply pulling a release mechanism.

  • Patent number: 8771274
    Abstract: A surgical drill for providing holes at an angle for use in repair and replacement of the ACL is disclosed, generally comprising a drill guide having a head that is angularly adjustable with respect to a body, a flexible guide pin and a flexible drill. The adjustable head of the drill guide allows a surgeon to drill a hole in the femur at an angle to a tunnel provided in the tibia. Because the surgeon can access the femur via the hole in the tibia, the surgical drill of the present invention obviates the need for a second hole in the tissue and also makes placement of femur hole more precise for securement of the ligament or tendon graft within the hole.

  • Patent number: 8617063
    Abstract: A blade assembly has a blade body and a blade body surround. A retractor attachment structure is attached to the blade body at the first end portion thereof extending from an exterior surface thereof. The retractor attachment structure is configured for having one of the blade body mounting structures of the retractor engaged therewith in a manner whereby the blade body is independently pivotable about and translatable along the blade body mounting structure. An alignment member protrudes from an interior surface of the blade body adjacent its first end portion. A slot extends through the blade body at its first end portion. The blade body surround and the blade body jointly form a generally cylindrical-shaped structure when the blade body is in a seated position within the slot. The cylindrical structure defines a central passage extending between the first and second end portions of blade body surround.

  • Patent number: 7244264
    Abstract: An integrated lancing test strip includes a pair of blade members that each have a lancing tip that are configured to lance skin. A pair of spacer members connect the blade members together such that the blade members define an internal capillary. A test strip is positioned along the internal capillary, and the test strip is configured to test analyte levels in the bodily fluid. During use, the lancing tips form one or more incisions in the skin. The fluid from the incisions is drawn via capillary action through the internal capillary and onto the test strip.

  • Patent number: 6800080
    Abstract: Immobilization and/or retrieval of material from a body can be accomplished, in accordance with the invention, with a device that includes a sheath and a basket. The basket is movable relative to the sheath from a retracted position in which the basket is withdrawn within the sheath and an expanded position in which the basket is extended beyond the distal end of the sheath and open. The basket has a first portion and a second portion with two or more legs extending from the first portion to the second portion. The basket further includes an intermediate portion between the first and second portions in which the legs are spirally arranged, substantially parallel, and non-intersecting. The intermediate portion of the basket is displaced radially outward relative to the first and second portions when the basket is in the expanded position. The basket in the expanded position may be used to immobilize and/or capture material within a body.

  • Patent number: 6607547
    Abstract: Apparatus and method for dilation of tissue utilize a tissue expansion device positioned on an inner cannula with an outer overlying expansive sheath that expands upon translation of the tissue expansion device therethrough. The tissue expansion device may be an olive or wedge formed near the tip of the cannula, and the expansible sheath includes two elongated shells that are fixably attached near proximal ends, and that are resiliently connected near distal ends. Translating the tissue expansion device through the expansible sheath expands the dimension of the shells to provide even dilation of surrounding tissue. Additionally, tissue dilation is performed in one continuous motion of retracting the inner cannula through the expansible sheath or pushing the tissue expansion device through the expansible sheath. The outer expansible sheath may be removed from the inner cannula to provide a dissection instrument having minimal outer diameter.

  • Patent number: 6527787
    Abstract: Methods and devices for harvesting veins from the body. The methods and devices allow vein harvesting using laparoscopic procedures. A working space is created over the vein using standard laparoscopic procedures and a side-hooked wire is inserted into the working space and twisted to insert the side-hook under the vein. The wire is then pulled or drawn along the vein to separate the vein from the surrounding tissue. In an alternative embodiment, vein separation is accomplished by threading a soft rubber tube under the vein, grasping the ends of the tube so as to surround the vein, and then pulling the tube along the vein. In other embodiments, the working space is created with everting balloons.
