20140378775 | Unitary multilumen cranial bolt - A unitary multilumen cranial bolt for use in multimodal monitoring of a plurality of physiological parameters in brain tissue incorporates a plurality of lumens, each lumen directing a catheter borne sensor through a bore hole in the cranium and into brain tissue of a patient. The lumens are configured to cause the catheters to splay outward as they enter the cranial cavity and reach their intended depth of penetration. Each lumen is associated with a guide. The guides are adapted for use with introducers that enable fragile and/or flexible sensors to be introduced into brain tissue. Each catheter borne sensor can be positioned and repositioned within brain tissue independently of all other sensors. | 12-25-2014 |
20140303513 | Edema Monitor - An edema monitor uses patient-specific measurements of tissue conductivity and tissue perfusion and an empirically developed perfusion coefficient of thermal conductivity to obtain tissue intravascular water and tissue extravascular water components of tissue total water. Edema is an excess of tissue extravascular water. A value for edema is obtained by deducting from the obtained value for tissue extravascular water a normal value for tissue extravascular water. | 10-09-2014 |
20130218046 | System for assessing endothelial function - The system assesses the endothelial function of a subject. Particularly, peripheral tissue perfusion measurements taken in a subject are compared to reference perfusion data and the comparison yields the assessment of endothelial function. The reference may be data indicative of peripheral tissue perfusion in a healthy person. Also, peripheral tissue perfusion measurements taken in a subject when perfusion is in an unperturbed state (the reference) can be compared to perfusion measurements taken promptly after a challenge to normal or unperturbed tissue perfusion of the subject. | 08-22-2013 |
20130218034 | System for quantifying blood flow in tissue and updating tissue baseline conditions - Methods and apparatus for determining blood flow in tissue are disclosed. The methods and apparatus are used to establish a baseline for both thermal properties of the tissue and non-physiologic conditions. Periodic changes in either or both constituents of the baseline are determined and, when the changes correspond to a need for a new baseline, a new baseline is established. | 08-22-2013 |

The methods and apparatus are used to establish a baseline for both thermal properties of the tissue and non-physiologic conditions. Periodic changes in either or both constituents of the baseline are determined and, when the changes correspond to a need for a new baseline, a new baseline is established. | 09-23-2010 |

20090216136 | Blood flow monitor with arterial and venous sensors - A technique is disclosed for determining blood flow in a living body by changing the thermal energy level in the venous blood flow path and determining temperatures in both the venous and arterial blood flow paths. Blood flow is calculated as a function of the change in energy level and the temperature differences in the venous and arterial blood flow paths. | 08-27-2009 |
