    摘要: A method for estimating the physiological parameters defining the edema induced upon infusion of fluid from an intraparenchymally placed catheter including; acquisition of patient-specific medical data; estimation of pertinent tissue microstructure based on the patient-specific medical data and/or generalized information derived or drawn from one or more of the following: experience, literature, modeling, studies, research, analysis; acquisition of information about delivery parameters, and/or delivery device geometry, and/or fluid properties, such as: delivery device trajectory, flow rate, pressure, catheter diameter, catheter profile, fluid viscosity, fluid molecular size; and computing a field of values of predicted extracellular volume fraction over the tissue region using the information obtained above. According to a further aspect, a method of infusing or planning and/or monitoring an infusion of a contrast agent such that the distribution of such agent can be detected by medical data acquisition and observing and/or measuring the backflow length along the catheter track.

    摘要: A method for estimating the physiological parameters defining the edema induced upon infusion of fluid from an intraparenchymally placed catheter including; a) acquisition of patient-specific medical data; b) estimation of pertinent tissue microstructure based on the patient-specific medical data and/or generalized information derived or drawn from one or more of the following: experience, literature, modeling, studies, research, analysis; c) acquisition of information about delivery parameters, and/or delivery device geometry, and/or fluid properties, such as: delivery device trajectory, flow rate, pressure, catheter diameter, catheter profile, fluid viscosity, fluid molecular size; and d) computing a field of values of predicted extracellular volume fraction over the tissue region using the information obtained in (b) and (c). According to a further aspect, a method of infusing or planning and/or monitoring an infusion of a contrast agent such that the distribution of such agent can be detected by means of medical data acquisition (e.g. MRI, CT, x-ray, ultrasound, SPECT, PET) and observing and/or measuring the backflow length along the catheter track.

    摘要: Surgery is performed on a patient with a novel device by: excising tissue from tissue mass within a patient to create a cavity within the tissue mass; inserting a novel device of this invention into the cavity; shaping a flexible expandable component of the device to adjust dimensions on the flexible expandable component; providing a liquid into the component through the liquid input port; and controlling pressure or flow rate of the liquid in the component to move the liquid through the multiple openings and into the cavity. The device has a liquid inlet port, an exterior surface having length, width and depth, and multiple openings in the surface distributed throughout the length, width and depth to act as liquid delivery ports; the exterior surface of the liquid delivery device being shapeable by internal pneumatic pressure or hydraulic pressure to better fit inside dimensions of a surgical cavity; the multiple openings deliver the liquid through the multiple openings.
