摘要:
Various exemplary methods and devices are provided for fixing an implant to native tissue, such as, bone. The devices can include a body having an upper surface, a lower tissue contacting surface, and an implant receiving opening extending therebetween. The body can further include first and second portions each having an implant contacting surface and a hinge for connecting the first and second portions. In use, the hinge can allow pivotal movement between the first and second portions such that an implant can be fixed therebetween.

A sensor is provided that is appropriate for transcutaneous detection of tissue or blood constituents. A sensor for tissue constituent detection may include a gas collection chamber with a conduit to a sensing component and a conduit from the sensing component to the chamber. A sensor as provided may also include a barrier layer to prevent water from infiltrating the sensor.

In the repair/regenerate of the intervertebral disc, all or a portion of the nucleus pulposus or annulus fibrosus is excised and treated for reinsertion into the disc or adjacent or alternate level disc. Alternatively certain bioactive agents may be injected into the degenerative disc without excising disc material.
摘要:
Apparatus for conducting operations on one or more spectacle lenses comprising: means for mounting on the apparatus one or more operating tool(s) adapted for at least shaping and/or drilling and/or buffing the or each lens, using one or more drilling and/or shaping tool(s) comprising one or more cutting diameters, means for displacing three-dimensionally the operating tool so that the tool is able to follow the path or paths of operation necessary to carry out its functions, one or more clamps each holding in use a single spectacle lens.
摘要:
Spinal implants and methods for spinal stabilization and/or fusion are provided. Exemplary implants described herein can be configured for delivery to a facet joint to stabilize and/or fuse the facet joint, and can optionally be anchored within the pedicle for added fixation. The implant can optionally include a fusion-promoting bioactive material thereby providing a single device capable of spinal stabilization and/or fusion. Furthermore, a method of placing such an implant within a facet joint is provided.

Embodiments disclosed herein may include systems and methods for determining a patient's respiratory effort and blood oxygen saturation based on data acquired from a pulse oximetry sensor and analyzing the parameters in conjunction with each other. For example, the respiratory effort may be determined based on a photo-plethysmographic waveform generated from light attenuation detected by the sensor, and the blood oxygen saturation may be a pulse -based estimate of arterial blood oxygen saturation determined from the detected attenuation. Analysis of the parameters may enable detection and classification of apnea (e.g., obstructive or central) or another underlying cause for respiratory instability. Furthermore, the measured respiratory effort may be compared to respiratory effort supplied by a ventilator to ensure proper sensor placement before enabling automatic adjustment of ventilator settings.
摘要:
A method of performing a procedure on an intervertebral disc includes inserting a cannulated delivery tube through an opening in an annulus fibrosus of the intervertebral disc, positioning an expandable portion of the tube within the opening in the annulus fibrosus, expanding the expandable portion into contact with the annulus fibrosus about the opening to create a seal between the expandable portion and the annulus fibrosus, performing a procedure through the cannulated delivery tube within the annulus fibrosis, removing the tube, and closing the opening in the annulus fibrosus.
