| 20100114301 | Vessel Right Sizer - An anastomotic device includes a tube and anastomotic coupler rings having vessel openings attached to each end of the tube. In an embodiment, the diameters of the vessel openings are different. | 05-06-2010 |
| 20100114293 | Multibranch Vessel Extender - An anastomotic device has a tube with three or more tube portions that are connected together. A first anastomotic coupler ring is attached to a first tube portion. A second anastomotic coupler ring is attached to a second tube portion. In an embodiment, a third anastomotic coupler ring is attached to a third tube portion. | 05-06-2010 |
| 20100114292 | Vessel Extender - An anastomotic device includes a tube and anastomotic coupler rings having vessel openings attached to each end of the tube. In an embodiment, the diameters of the vessel openings are the same. | 05-06-2010 |
| 20090326354 | Noninvasive Sensor Housing - A flexible sensor pad includes a cavity to hold a sensor unit with an attached cable. According to one aspect of the present invention, a light-shielding layer is coupled to a bottom surface of the sensor pad, surrounds the sensor unit, and extends past two sides of the sensor pad. A transparent adhesive layer is coupled to the light-shielding layer and extends past two sides of the light-shielding layer. Another light shielding layer is coupled to a top surface of the sensor pad and covers the sensor unit. The cable divides the sensor pad into a first side and a second side which are mirror images of each other. | 12-31-2009 |
| 20090292187 | Device for Assessing Ischemia in Nerve Root Tissue Using Oxygen Saturation - A retractor has an oximeter sensor at its tip, which allows measuring of oxygen saturation of a tissue being retracted by the retractor. The tip includes one or more openings for at least one source and detector. A specific implementation is a spinal nerve root retractor with an oximeter sensor. | 11-26-2009 |
| 20090149715 | Surgical Elevator Oximeter - A surgical elevator has an oximeter sensor at its tip, which allows measuring of oxygen saturation of a tissue. | 06-11-2009 |
| 20080319290 | Tissue Retractor Oximeter - A retractor has an oximeter sensor at its tip, which allows measuring of oxygen saturation of a tissue being retracted by the retractor. The tip includes one or more openings for at least one source and detector. A specific implementation is a spinal nerve root retractor with an oximeter sensor. | 12-25-2008 |
| 20080316488 | Measuring Cerebral Oxygen Saturation - A device includes source and detector sensors. In a specific implementation, the device has two near detectors, two far detectors, and two sources. The two near detectors are arranged closer to the two sources than the two far detectors. A light-diffusing layer covers the two near detectors. The device may be part of a medical device that is used to monitor or measure oxygen saturation levels in a tissue. In a specific implementation, light is transmitted into the tissue and received by the detectors. An attenuation coefficient is first calculated for a shallow layer of tissue. The attenuation coefficient is then used to calculate an attenuation coefficient for a deep layer of tissue. | 12-25-2008 |
| 20080269621 | Diagnosing Peripheral Vascular Disease by Monitoring Oxygen Saturation Changes During an Ischemia Phase - Peripheral vascular disease is diagnosed through measurements of oxygen saturation. In a specific implementation, peripheral vascular disease is diagnosed based on changes in oxygen saturation in tissue. Ischemia is induced, and then measurements of changes in oxygen saturation in tissue are made. Based on changes in oxygen saturation during the induced ischemia phase, a diagnosis is provided of whether a patient has or does not have peripheral vascular disease. | 10-30-2008 |
| 20080269620 | Diagnosing Peripheral Vascular Disease by Monitoring Oxygen Saturation Changes During an Accumulation Phase - Peripheral vascular disease is diagnosed through measurements of oxygen saturation. In a specific implementation, peripheral vascular disease is diagnosed based on changes in oxygen saturation in tissue. Ischemia is induced, and measurements of changes in oxygen saturation in tissue are made. Based on changes in oxygen saturation during an accumulation phase, a diagnosis is provided of whether a patient has or does not have peripheral vascular disease. | 10-30-2008 |
| 20080269574 | Diagnosing Peripheral Vascular Disease by Monitoring Oxygen Saturation Changes During a Hyperemia Phase - Peripheral vascular disease is diagnosed through measurements of oxygen saturation. In a specific implementation, peripheral vascular disease is diagnosed based on changes in oxygen saturation in tissue. Ischemia is induced, and then measurements of changes in oxygen saturation in tissue are made. Based on changes in oxygen saturation during a hyperemia phase, a diagnosis is provided of whether a patient has or does not have peripheral vascular disease. | 10-30-2008 |
