  • Patent number: 9597019
    Abstract: A method of operating a glucose test meter is provided. The method can be achieved by storing a plurality of glucose readings to a first memory of the test meter, each of the glucose readings having a time stamp and an order index, the time stamp comprising a date and a time when the glucose reading was performed, the order index indicating an order in which the plurality of glucose readings was saved to the first memory; determining whether successively saved glucose readings have time stamps in chronological order consistent with the order index; and indicating that the date and the time setting in the test meter is incorrect if there are successively saved glucose readings having time stamps inconsistent with the order index.

  • Patent number: 8758245
    Abstract: A diabetes management system or process is provided herein that may be used to analyze and recognize patterns for a large number of blood glucose concentration measurements and other physiological parameters related to the glycemia of a patient. In particular, a method of monitoring glycemia in a patient may include storing a patient's data on a suitable device, such as, for example, a blood glucose meter. The patient's data may include blood glucose concentration measurements. The diabetes management system or process may be installed on, but is not limited to, a personal computer, an insulin pen, an insulin pump, or a glucose meter. The diabetes management system or process may identify a plurality of pattern types from the data including a testing/dosing pattern, a hypoglycemic pattern, a hyperglycemic pattern, a blood glucose variability pattern, and a comparative pattern.

  • Patent number: 8172783
    Abstract: The invention presents is a fluid isolation system and method for confining fluid is a biological mass having at least one upstream channel and downstream channel. The system includes a delivery conduit for administering fluid to the biological mass and a collection conduit having and external seal and for retrieving the fluid. In the use of the system, the delivery conduit is positioned adjacent to or into the upstream channel and the collection conduit is inserted adjacent to or into the downstream channel. In one manner to confine the fluid, the seal on the collection catheter is activated to occlude outside fluid flow and divert the fluid into the lumen of the catheter.

  • Publication number: 20110245634
    Abstract: Described herein is a method of analyzing an analyte distribution from discrete, quasi-continuous or continuous measurements to determine a glycemic state of a patient in order to understand how often, and for how long, a patient's post-prandial glucose is out of control without requiring laboratory blood test and especially post-prandial levels laboratory analysis. The systems, devices, and methods assist in predicting risk levels of developing diabetes-associated complications. Therefore applicants have recognized also a need for a tool which facilitates stratification of patients for risk of and/or onset of one or more complications having the same HbA1c level.

  • Patent number: 7150738
    Abstract: A catheter assembly is provided having a balloon disposed at the distal end thereof. The balloon is capable of being inflated to selectively dilate from a collapsed configuration to an expanded configuration. A syringe assembly is in fluid communication with a delivery lumen of the catheter assembly for allowing a therapeutic substance to be injected into a tissue of a passageway. The syringe assembly includes a portion capable of pivoting from a first position towards a second position when the balloon is being inflated from the collapsed configuration to the expanded configuration. The portion of the syringe assembly is also capable of pivoting from the second position back towards the first position when the balloon is being deflated.

  • Patent number: 6902556
    Abstract: A method and device for occluding a patient's ascending aorta, maintaining circulation of oxygenated blood in the patient and delivering cardioplegic fluid to arrest the patient's heart. An aortic occlusion catheter has an occluding member for occluding the ascending aorta. The aortic occlusion catheter passes through a cannula. Delivery of oxygenated blood is accomplished through either the cannula of the aortic occlusion catheter. In another aspect of the invention, an arterial cannula having a curved or angled distal portion. An introducer straightens the distal portion for introduction into the patient. In still another aspect of the invention, an open-mesh stabilizer is used to stabilize a discoid occluding member.

  • Patent number: 6599267
    Abstract: A catheter including an injection port at or near the distal end thereof and a mechanism for causing the injection port to move between a first position and a second position. In the first position the injection port is substantially aligned with a central axis of the catheter. Upon activation of the mechanism, the injection port moves between the first position and the second position perpendicular to the central axis of the catheter. The mechanism also causes the injection port to move away from the central axis of the catheter and into a wall of the vasculature.

  • Publication number: 20020072708
    Abstract: A device and method for occluding a patient's ascending aorta, maintaining circulation of oxygenated blood in the patient and delivering cardioplegic fluid to arrest the patient's heart. An aortic occlusion device has an occluding member in the form of a non-inflatable structure which is moved mechanically between collapsed and expanded orientations. The device is introduced into the ascending aorta in its collapsed orientation and is moved to its expanded orientation to occlude the aorta. The aortic occlusion includes a lumen through which blood is delivered to the patient. The lumen may be provided in the aortic occlusion device or in a separate cannula coupled to the device.
