20090043184 | CATHETER AND PROBE FOR MEASURING ANALYTES OR OTHER PARAMETERS - A medical sensing system including an access tube with a fluid infusate lumen and a sensing probe that can be passed through a second lumen in the access tube and extended into the vasculature for sensing a blood parameter. The sensing probe has a sensor on a distal end thereof and a shape that permits it to extend from the access tube such that the sensor is displaced laterally from the access tube, and out of the infusate flow. If the sensing probe passes through the lumen opening at the distal tip of the catheter, the distal end of the probe bends or otherwise deflects laterally so that the sensor is displaced laterally from the infusate flow path. Alternatively, the probe may exit a side port of the access tube upstream of an infusate side port. The deflectable probe is particularly useful for sensing glucose in blood through any number of conventional, off-the-shelf catheters. | 02-12-2009 |
20090312622 | Device And Method For Determining A Value Of A Physiological Parameter Of A Body Fluid - A device for determining a value of a physiological parameter of a body fluid of a body under investigation, the device comprising a fluid reservoir for containing a perfusate fluid, a body interface insertable into the body under investigation for a fluid communication between the fluid reservoir and the body fluid, a fluid conduit between the fluid reservoir and the body interface, a bidirectional fluid transport unit for transporting the perfusate fluid from the fluid reservoir through the fluid conduit a the body interface into the body under investigation and for subsequently transporting a mixture of the perfusate fluid and the body fluid from the body under investigation through the body interface into the fluid conduit, and a sensor for sensing the value of the physiological parameter based on an analysis of the mixture of the perfusate fluid and the body fluid. | 12-17-2009 |
20120203089 | MONITORING SYSTEMS AND METHODS WITH FAST INITIALIZATION - Some embodiments provide a system for synchronizing and configuring monitoring devices. In some embodiments, a patient monitoring device settings module is configured to automatically provide configuration settings to a plurality of patient monitoring devices. A monitoring device data module is configured to receive measurement data from at least one of the patient monitoring devices. An electronic medical records system interface is configured to provide patient data at least partially derived from the received measurement data to an electronic medical records system. A patient records interface is configured to provide patient data to at least one of the patient monitoring devices. | 08-09-2012 |
20130165758 | MINIATURE INFUSION PUMP - A miniature infusion pump (MIP) suitable for use with a human patient is configured for non-human animal testing. In one example, a MIP includes an electromagnetic piston pump, a circuit board, and a housing. The pump is configured to deliver a therapeutic agent from a reservoir through an implantable catheter. The circuit board includes programmable electronics configured to control the pump to deliver the therapeutic agent through the catheter. The pump and the circuit board are sealed within the housing. The MIP is sized to be at least one of harnessed to or implanted in a non-human test subject including a weight greater than or equal to approximately 150 to approximately 250 grams. | 06-27-2013 |
20130225961 | DIALYSIS PROBE - A dialysis probe includes a tubular dialysis membrane sealed at its tip, a support tube coupled at a tip to a rear end of the dialysis membrane, a cap portion for securing a rear end of the support tube, an inlet conduit extending through the cap portion toward the tip of the dialysis membrane within a space to guide a perfusate into the space, an outlet conduit extending through the cap portion toward the tip of the dialysis membrane within the space to guide the perfusate in the space outside the space, and at least one air-exposure through-hole provided in the cap portion for maintaining the space at atmospheric pressure. The inlet conduit has a longer protruding length from the rear end of the support tube when compared to the outlet conduit. | 08-29-2013 |
20140081109 | Microdialysis Sampling/Delivery Device - This present invention provides real-time in vivo sampling via ultra-small volume microdialysis of the intervertebral disc to assay single molecules of interest. The invention consists of three lumena, two that are capped with a membrane capable of sampling tissues via diffusion. A guide wire can provided between these two lumena so that they may be extended beyond the housing of the three lumena and directed via the guide wire. The third lumen can be utilized for injection or aspiration. Theoretically, agents including treatments such as stem cells or pharmaceutical agents may be introduced to the disc via this third lumen and the real-time effects may be assayed with the first two lumena. The three lumena may be placed adjacent to each other or in a concentric fashion to minimize the total size of the device. | 03-20-2014 |
20140296677 | METHOD OF MEASURING TOTAL VASCULAR HEMOGLOBIN MASS - A method of measuring total vascular hemoglobin mass. One step of the method is to store a volume of fluid to be injected using a processor. A hemoglobin value is measured in vivo on a substantially continuous basis. The method also measures a total circulating vascular volume based on the volume of fluid to be injected by detecting a change in blood concentration over a period of time upon injection of a fluid into a body. The total hemoglobin mass is calculated based on the measured hemoglobin value and the measured total circulating vascular volume. | 10-02-2014 |
