Abstract:
A nucleus pulposus implant that can be converted to an interbody fusion cage is provided. Kits including the nucleus pulposus implant and other delivery components are also provided. Methods of delivering the implant into a damaged disc space are also provided.
Abstract:
A binder mechanism is disclosed having a first ring assembly and a binding portion. The first ring assembly includes at least one first ring half. At least the first ring assembly or the binding portion are a pivotable half that is pivotable with respect to the other to a locked position about a first longitudinal axis. In the locked position, the first ring half is engaged with the binding portion cooperatively defining a loop that is substantially closed to retain a stack of papers or a workpiece. The first ring assembly and the binding portion are lockable with respect to each other in the locked position to prevent pivoting of the pivotable half from the locked position. At least one of the first ring assembly and the binding portion is movable with respect to the other from the locked position in an unlocking direction oriented at less than 180° from the longitudinal axis to permit the pivotable half to pivot about the longitudinal axis to an open position in which the loop is substantially open.
Abstract:
Systems and methods for increasing bandwidth capability of an envelope elimination and restoration (EER) transmitter. A frequency response of a power supply modulator of the transmitter is approximated. An inverse response is applied to the envelope signal prior to digital-to-analog conversion (DAC) and before the signal reaches the power supply modulator to pre-emphasize the signal thereby counteracting distorting affects of the modulator. The filter is implemented using any of a variety of different digital techniques including programmable logic, DSP, etc.
Abstract:
Disclosed is an improved disposable exercise glove. The device includes a latex glove with an opening for each finger section, a flock-lined interior, and a padded palm area. The flock lining enables a user to easily don the gloves, while the padding provides an enhanced grip when grasping exercise equipment. The gloves can be worn and disposed of after a single use or can be reused as desired. The present invention is substantially all in one piece, and is easy to put on and take off of the user's hand. The disposable exercise glove is composed of resilient material that not only readily adjusts itself to the user's hand when placed thereon, but snugly and tightly fits the same. The present invention provides a hygienic and protective barrier to make otherwise long or strenuous workouts more comfortable.
Abstract:
A first tool is configured to cut a polymer implant, and includes a handle, a cutting portion, and a bending portion. A second tool is configured to cut a polymer implant, and includes a handle, a first cutting portion, and a second cutting portion. The cutting portions contain a cutter that is preferably a blade. In the second tool, the blades are preferably angled with respect to each other between about 45°. The tools can be used to reshape an implant that is to be used to replace a portion of a skull.
Abstract:
The present invention is directed to a resorbable containment device for use in treating voids in bone and restoring the anatomy of diseased or fractured bone. The resorbable containment device may be a balloon of varied size or shape to conform to the bone to be treated and may be deployed in any type of bone where collapsed fractures of cortical bone may be treated by restoring the bone from its inner surface. The containment device may be formed from a pluronic based polymer and may degrade in-vivo within a period of weeks after implantation into bone. The balloon may have multiple layers to provide desired surface characteristics, resistance to puncture and tearing, or other beneficial properties, as appropriate for the particular application of the device.
Abstract:
A portable eye washing station includes a spike that can pierce a fluid source and the spike is hollow to pass fluid therethrough. A feed tube is fluidly coupled to the spike to receive the fluid from the spike. A fitting is fluidly coupled to the second end of the feed tube and the fitting has a pair of outputs to pass the fluid therethrough. A distribution tube is fluidly coupled to each of the outputs on the fitting such that the distribution tube forms a closed loop for wearing around a user's head. A cannula is fluidly coupled to the distribution tube to release the fluid and the cannula has a pair of outlets. Each of the outlets is aligned with a respective one of the user's eyes when the distribution tube is worn around the user's head. Thus, each of the outlets directs the fluid into the user's eyes for flushing the user's eyes.
