The band may have a structural portal to be used for filling, or it may simply be constructed of a fabric-like material that allows a fill tube to perforate its walls to allow for filling. In the latter case, the perforated wall tends to self-seal once the fill tube is withdrawn. The band may be flat or tubular in cross-section. However, unlike a balloon, the band does not require either a bottom or a top, as we found that a top and bottom are unnecessary when using a band or hoop to enclose material injected into a reamed out intervertebral space.Type: GrantFiled: September 29, 2010Date of Patent: June 10, 2014Assignee: Spineology, Inc.Inventor: Patricia Kacian Kuslich

Patent number: 8747476Abstract: An implant for use in spinal surgery comprises a resilient element having an inflatable cavity. It is formed of a biologically compatible material and is arranged for placement between end plates of adjacent vertebra. The implant may also include a wound disc replacement element. A method of performing spinal surgery on a patient comprises securely mounting a patient onto a patient support table; imaging a spinal region of the patient; building up a three-dimensional image file of the spinal region of the patient; storing the image file; and utilizing the image file for planning and carrying out computer controlled spinal surgery on the patient utilizing the implant. A computer-controlled surgical implant system comprises a steerable endosurgical implanting assembly operative to install the implant at a desired location in a patient; and a computerized controlled, which operates the steerable endosurgical implanting assembly.Type: GrantFiled: March 23, 2012Date of Patent: June 10, 2014Assignee: NuVasive, Inc.Inventor: Amiram Steinberg

Patent number: 8747478Abstract: A prosthetic patellar implant has a posterior articulation surface and an anterior attachment surface. The anterior attachment surface has a medial attachment surface and a lateral attachment surface. The medial and lateral attachment surfaces can be planar and angled relative to one another, meeting at a common intersection medially offset from the sagittal centerline of the implant. The medial and lateral attachment surfaces can include convexities. The anterior attachment surface can have one or more pegs and/or recesses.Type: GrantFiled: February 6, 2012Date of Patent: June 10, 2014Assignees: IMDS CorporationInventors: Michael Ries, Nicholas Slater, Joshua A.

Patent number: 8747480Abstract: Methods and devices are disclosed for manipulating alignment of the foot to treat patients with flat feet, posterior tibial tendon dysfunction and metatarsophalangeal joint dysfunction. An inflatable implant is positioned in or about the sinus tarsi and/or first metatarsal-phalangeal joint of the foot. The implant is insertable by minimally invasive means and inflatable through a catheter or needle. Inflation of the implant alters the range of motion in the subtalar or first metatarsal-phalangeal joint and changes the alignment of the foot.Type: GrantFiled: June 20, 2011Date of Patent: June 10, 2014Inventor: Victor V. Cachia

Patent number: 8747482Abstract: An orthopaedic prosthesis includes a curved outer surface configured to abut a patient's bone when the orthopaedic prosthesis is implanted therein. The outer surface may or may not be electrically conductive. A channel is defined in the outer surface in which one or more electrical conductors are positioned. A switch is positioned at a first location on the outer surface and is configured to establish an electrical connection between the electrical conductor and the outer surface (e.g., an electrical trace) and/or another electrical conductor when the first location of the outer surface is pressed against the patient's bone. The switch may be embodied as an end of the electrical conductor or a more complex switch such as a push-button type switch.Type: GrantFiled: December 18, 2012Date of Patent: June 10, 2014Assignee: DePuy Synthes Products, LLCInventors: Said Gomaa, Jason Sherman

Patent number: 8747483Abstract: Apparatus and methods for closing a septal defect including a flap of tissue partially detached from a septum of a heart. A needle is advanced through a patient's vasculature within a delivery apparatus until the needle is disposed within a first chamber adjacent the septum. The needle is directed through the flap of tissue until the needle is disposed within a second chamber opposite the septum. A filament attached to an intermediate region of the needle is pulled, thereby causing the needle to pivot about the intermediate region such that the ends of the needle straddle the septal opening. A locking element is secured to the filament to secure the flap of tissue against the septum, and the filament is cut. Alternatively, the filament is biased to coil to engage the flap of tissue and secure the needle against the septum to close the opening.Type: GrantFiled: November 16, 2012Date of Patent: June 10, 2014Assignee: Promed, Inc.Inventor: Richard S. Ginn
