| 20080287985 | Disposable surgical instrument having a locking device - The present invention discloses a surgical instrument having a locking device which locks the instrument in a closed position while bearing a load. The surgical instrument, which may function as forceps, or a tanaculum, is constructed of a disposable material in order to provide a single use medical instrument. By constructing the invention of a disposable material, the unique shape of the disclosed embodiment allows movement of the arms in order to allow tip penetration along the path of least resistance while also minimizing tissue damage and bleeding. The locking device described may further be used on other instruments. | 11-20-2008 |
| 20090093820 | ADJUSTABLE SPINAL STABILIZATION SYSTEMS - A spinal stabilization system includes a stabilization member with opposite end portions lying along a longitudinal axis and an adjustment mechanism between the end portions that allows the end portions to be moved toward and away from one another along the longitudinal axis. | 04-09-2009 |
| 20090248083 | ELONGATED CONNECTING ELEMENT WITH VARYING MODULUS OF ELASTICITY - A spinal system comprising a spinal rod with an outer wall, a proximal end, a distal end, and a first axis extending centrally through the spinal rod between the proximal and the distal ends. The spinal rod comprises a first region having a first modulus of elasticity, a second region having a second modulus of elasticity different from the first modulus of elasticity, and a third region between the first and second region having a modulus gradation ranging from the first modulus of elasticity to the second modulus of elasticity. | 10-01-2009 |
| 20090275986 | FLEXIBLE SPINAL STABILIZATION ELEMENT AND SYSTEM - Systems and devices for providing dynamic stabilization of one or more spinal motion segments are provided. The systems include a connecting element between two or more bone anchor assemblies that can be attached to two or more vertebral bodies of at least one spinal motion segment. The connecting element includes a first end, a second end, an intermediate resilient element and a sheathed tether extending from the first end to the second end and through the resilient intermediate element. | 11-05-2009 |
| 20090306480 | SYSTEMS AND METHODS FOR TISSUE RETRACTION - A retractor system for percutaneous surgery in a patient includes first and second retractor portions positionable opposite one another in an incision of the patient. An actuating member is coupled with and extends between ends of the retractor portions which are positionable above the incision. The actuating member is in communication with a controller which includes a user interface for receiving actuation commands from the user. In response to actuation commands, the actuating member is actuated and its length is adjusted to position the first and second retractor portions relative to one another in the incision. In another form, a method is directed to retracting tissue for percutaneous access to a surgical site in a patient. However, other embodiments, forms and applications are also envisioned. | 12-10-2009 |
| 20100004685 | IMPLANTABLE DEVICE AND METHOD OF FORMING - An implantable device includes a first arm member, a second arm member, a compressible member disposed between and coupled to the first arm member and the second arm member, and a tensioning member coupled to the first arm member and the second arm member. Wherein upon moving the first arm member toward the second arm member the tensioning member translates within the first arm member. | 01-07-2010 |
| 20100198261 | ADJUSTABLE SPINAL STABILIZATION SYSTEMS - A spinal stabilization system includes a stabilization member with opposite end portions lying along a longitudinal axis and an adjustment mechanism between the end portions that allows the end portions to be moved toward and away from one another along the longitudinal axis. | 08-05-2010 |
| 20100222644 | SURGICAL ACCESS INSTRUMENT - Embodiments of the invention include instruments and methods for providing surgical access to a surgical site. Some embodiments include a flexible arm that adjustably holds a retractor blade to enable access to the surgical site. | 09-02-2010 |
| 20100234954 | SPINAL IMPLANT AND METHODS OF IMPLANTATION AND TREATMENT - A spinal implant is provided that includes a first component for engaging a first vertebra, a second component for engaging a second vertebrae, and a damping member is positioned therebetween. The damping member has at least two chambers connected by an opening. A fluid is disposed within the chambers such that compression of the first and second components towards one another causes the fluid to be displaced from one of the chambers to another chamber through an opening. The opening has a reduced size relative to the chambers to restrict the flow of the fluid between the chambers and provide a dampening effect. In some instances, the rheologic properties of the fluid positioned within the chambers are dependent upon the strength a magnetic field passing through the fluid. In other aspects of the present disclosure, prosthetic devices, intervertebral implants, spinal systems, implantation methods, and treatment methods are provided. | 09-16-2010 |
