Patent number: 10631771Abstract: Methods and apparatus for blood sampling from skin capillaries are provided. Blood extraction is improved by applying gradient pressure in a proximal to distal direction of an extremity. Blood is extracted and sampled from the skin capillaries with a blood sampling mechanism of at least a lancet and testing kit.Type: GrantFiled: January 6, 2009Date of Patent: April 28, 2020Inventors: Morteza Naghavi, Albert Andrew Yen, Haider Hassan, David Panthagani, Craig Jamieson, Gary L. McQuilkin, Timothy J O'Brien

Patent number: 8986342Abstract: Methods for ischemic conditioning treatments of a chronic medical condition are provided. Baseline disease-related parameters of a patient with a chronic medical condition are measured. Ischemia is induced in the patient by occluding and releasing arterial flow in one or more extremities of the patient. Post-ischemia parameters in the patient are measured. The baseline and post-ischemia parameters are compared to provide an assessment of an ischemic conditioning treatment of a chronic medical condition. The repeated, scheduled delivery of ischemic conditioning provides a beneficial, therapeutic effect on the chronic medical condition. Also provided is a device for pulse oximetry during periods of absent or low pulsatile blood flow including an artificial pulse generator as well as the use of said device in assessment of ischemic conditioning.Type: GrantFiled: November 25, 2008Date of Patent: March 24, 2015Assignee: IC TherapeuticsInventors: Morteza Naghavi, Albert Andrew Yen, Haider Hassan, David Panthagani

Patent number: 8956387Abstract: A system and method for inducing physiological effects of ischemic conditioning and physiological effects of shear stress in a subject's body that mimic the effect of exercise on the subject. The disclosure includes a first device configured to cause ischemia, a second device configured to mechanically generate arterial shear stress, and a third device configured to monitor one or more of markers of ischemia or hemodynamic parameters and further including a microcontroller and actuators to cause the ischemia for a preset duration and then stop the ischemia for a preset duration, and to repeat the ischemia and reflow periods according to a preset program, simultaneously cause the second device to mechanically generate arterial shear stress according to a preset program of mechanical pulse amplitude, duration, and frequency; and to concurrently monitor hemodynamic parameters or markers of ischemia.Type: GrantFiled: December 12, 2013Date of Patent: February 17, 2015Assignee: IC Therapeutics Inc.Inventors: Morteza Naghavi, Albert Yen, Timothy O'Brien, Stephan Cleboski, Timothy Brinkley, David Panthagani

Publication number: 20100185220Abstract: Methods and apparatus for ischemic conditioning treatment in a patient are provided. Transient ischemia is caused by interrupting blood flow to a tissue. Markers of ischemia and metabolism are monitored in the tissue and the induced ischemia is adjusted based on the monitoring results.Type: ApplicationFiled: May 23, 2008Publication date: July 22, 2010Applicant: IC THERAPEUTICS, INC.Inventors: Morteza Naghavi, Albert Andrew Yen, Haider Hassan, David Panthagani

Publication number: 20100081941Abstract: Methods and apparatus for improving measurements of cardiovascular health status in a given individual are provided. The comprehensive assessment of cardiovascular health includes at least two components: risk factor assessment based on epidemiologic studies and functional status of the individual. Structural studies of the individual can also be included in the comprehensive assessment of cardiovascular health. The invention aims to improve detection, treatment, devices, and administration of cardiovascular risk assessment.Type: ApplicationFiled: December 21, 2007Publication date: April 1, 2010Applicant: Endothelix, Inc.Inventors: Morteza Naghavi, Robin Antony Owen, Albert Andrew Yen, Craig Jamieson, Haider Hassan, David Panthagani, Gary L.
