US Patent:

8088074, Jan 3, 2012

Filed:

May 17, 2010

Appl. No.:

12/781105

Inventors:

Robert A. Baruch - Ellicott City MD, US
Ken M. Brady - Ellicott City MD, US

Assignee:

Raba Equity Partners II, LLC - Ellicott City MD
The Johns Hopkins University - Baltimore MD

International Classification:

A61B 5/00

US Classification:

600483, 600323, 600328, 600481, 600485, 600504

Abstract:

A monitoring device may include logic to receive arterial blood pressure data associated with a patient and receive tissue hemoglobin data associated with the patient. The logic may also calculate a linear correlation between the arterial blood pressure data and the tissue hemoglobin data. The correlation may be used to assess vascular reactivity.

Filed:

Nov 26, 2010

Appl. No.:

12/954787

Inventors:

Ken M. Brady - Sugar Land TX, US
Robert A. Baruch - Ellicott City MD, US

International Classification:

A61M 1/00
A61M 1/14
A61M 1/36

US Classification:

422 48, 422 44, 422 45, 604 401, 604 501, 604 614

Abstract:

A method may include obtaining information representing at least one of a concentration of carbon dioxide in a patient's blood, a concentration of oxygen in the patient's blood or a pH value of the patient's blood. The method may also include setting an initial carbon dioxide tension in a membrane oxygenator of an extra-corporeal membrane oxygenation (ECMO) system based on the obtained information.

Filed:

Jan 4, 2008

Appl. No.:

12/525029

Inventors:

Ken M. Brady - Baltimore MD, US

Assignee:

Johns Hopkins University - Baltimore MD

International Classification:

A61B 5/00

US Classification:

600301, 600485, 600500, 600309

Abstract:

A method of diagnosing cerebrovascular autoregulation in a patient includes measuring blood pressure of the patient, measuring, non-invasively, venous oxygen content of the patient's brain substantially simultaneously with the measuring blood pressure, correlating the blood pressure and the venous oxygen content measurements in a time domain, and determining a cerebrovascular autoregulation state of the patient based on the correlating the blood pressure and the venous oxygen content measurements.

Filed:

Jul 29, 2008

Appl. No.:

12/181502

Inventors:

Robert A. BARUCH - Ellicott City MD, US
Ken M. BRADY - Owings Mills MD, US

International Classification:

A61B 5/02

US Classification:

600368, 600485

Abstract:

A monitoring device may include logic to receive arterial blood pressure data associated with a patient and receive tissue hemoglobin data associated with the patient. The logic may also calculate a linear correlation between the arterial blood pressure data and the tissue hemoglobin data. The correlation may be used to assess vascular reactivity.

US Patent:

Filed:

Mar 29, 2012

Appl. No.:

13/433348

Inventors:

Ken M. Brady - Sugar Land TX, US
Robert A. Baruch - Ellicott City MD, US

Assignee:

RABA EQUITY PARTNERS II, LLC - Ellicott City MD

International Classification:

A61B 5/026
A61M 1/36

US Classification:

600507, 604 611

Abstract:

A method may include controlling a bypass pump to introduce blood flow variations to a patient. The method may also include analyzing blood volume in the brain of the patient with respect to the blood flow variations and determining, based on the analyzing, whether an autoregulatory mechanism associated with the brain is operating properly.

US Patent:

20130190632, Jul 25, 2013

Filed:

Jan 24, 2013

Appl. No.:

13/748833

Inventors:

Robert A. Baruch - Ellicott City MD, US
Ken M. Brady - Sugar Land TX, US
Ronald B. Easley - League City TX, US
Craig G. Rusin - Houston TX, US

International Classification:

A61B 5/00
A61B 5/03
A61M 16/12
A61B 5/0205
A61M 16/00
A61M 16/20

US Classification:

600484

Abstract:

A method may include controlling a ventilator to introduce mean airway pressure (MAP) variations in a patient to induce slow waves of substantially fixed amplitude and period to the patient. The method may also include analyzing arterial blood pressure in the patient with respect to the MAP variations and determining, based on the analyzing, whether an autoregulatory mechanism associated with the patient's brain is operating properly.
