| 20090264754 | METHOD AND APPARATUS FOR EVALUATING OSTEOINTEGRATION OF MEDICAL IMPLANTS - Ultrasound vibrometry is employed to determine the amount of bony in-growth (i.e., osteointegration) into a surgically implanted prosthetic component (or conversely, the degree of implant looseness). While specifically developed for assessing osteointegration for total ankle replacements, the technique has broader application to any joint arthroplasty device. With respect to ankle arthroplasty, a vibration is induced in a patient's ankle in a range of frequencies. A Doppler ultrasound unit scans the ankle, with an imaging plane focused on an implant surface. The vibrations input into the ankle are sinusoidal frequencies, in a range from 80-500 Hz. At a frequency determined to best facilitate vibration of the ankle (e.g., a resonant frequency), the output signal from the Doppler ultrasound is Fourier transformed so that the frequency components of the output signal can be observed. These output Fourier signatures have been shown to correspond to a graded response of implant osteointegration (or looseness). | 10-22-2009 |

| 20090095869 | CONVERTIBLE DISPLAY STAND SYSTEM AND METHOD - A convertible mounting system for selectively positioning a flat panel display on either a generally horizontal surface or a generally vertical surface. In some embodiments, the convertible mounting system includes a first mount portion and a second mount portion. The first mount portion cooperates with the second mount portion in a first orientation to position a flat panel display on a generally horizontal surface. The first mount portion also cooperates with the second mount portion in a second orientation to position the flat panel display on a generally vertical surface. | 04-16-2009 |

| 20090287263 | MEDICAL DEVICE WITH LIQUID FILLED HOUSING - Embodiments of the invention are related to medical devices filled with a liquid composition, amongst other things. In an embodiment, the invention includes a hermetically sealed housing defining an interior volume, a component module disposed within the interior volume, the component module comprising a circuit board, the component module displacing a portion of the interior volume. A liquid composition can be disposed within the housing, the liquid composition filling at least 80% of the interior volume not displaced by the component module. Other embodiments are also included herein. | 11-19-2009 |

| 20110098763 | VENTED SET SCREW FOR IMPLANTABLE MEDICAL DEVICE - A vented set screw is used to secure a connection between an implantable medical device and an implantable lead. The vented set screw includes one or more venting channels that allow liquid and/or gas to flow out of the implantable medical device when the implantable lead is being inserted into the implantable medical device and secured during an implantation procedure. This prevents pressure from building up at the connection, thereby ensuring proper performance of sensing and/or therapy delivery functions of the implantable medical device. | 04-28-2011 |
