20130006230 | HYPERTHERMIA TREATMENT AND PROBE THEREFOR - A probe that emits energy to coagulate lesions is disclosed. The probe is constructed and arranged to emit light from its distal end, either at an angle to its longitudinal axis, or along its longitudinal axis. Optionally, an end reflector may be used to direct the energy in a beam to one side of the fiber end. An MRI system is arranged to generate a series of output signals indicative of temperature in the targeted area. The application of energy is stopped when the temperature at the boundary of the lesion reaches the required hyperthermic temperature. Cooling of the tip portion of the probe is effected by expansion of a supplied cooling fluid through a restrictive orifice into an expansion zone at the probe end to minimize collateral tissue damage. | 01-03-2013 |
20140012241 | HYPERTHERMIA TREATMENT AND PROBE THEREFOR - In vivo hyperthermia treatment of a target tissue can include imaging the target tissue with a magnetic resonance imaging (MRI) system, positioning a hyperthermia treatment probe in or proximate to the target tissue based on the imaging, and heating the target tissue by the probe. During the heating, changes in temperature of a volume of tissue that includes the target tissue can be monitored with the MRI system to determine an amount of the heating applied to the target tissue, and the heating can be terminated when the amount of the heating reaches a predetermined amount. | 01-09-2014 |
20140128881 | IMAGE-GUIDED THERAPY OF A TISSUE - Image-guided therapy of a tissue can utilize magnetic resonance imaging (MRI) or another medical imaging device to guide an instrument within the tissue. A workstation can actuate movement of the instrument, and can actuate energy emission and/or cooling of the instrument to effect treatment to the tissue. The workstation and/or an operator of the workstation can be located outside a vicinity of an MRI device or other medical imaging device, and drive means for positioning the instrument can be located within the vicinity of the MRI device or the other medical imaging device. The instrument can be an MRI compatible laser probe that provides thermal therapy to, e.g., a tissue in a brain of a patient. | 05-08-2014 |
20140288542 | HYPERTHERMIA TREATMENT AND PROBE THEREFORE - A method of using a probe that emits energy to coagulate lesions is disclosed. The probe is constructed and arranged to emit light from its distal end, either at an angle to its longitudinal axis, or along its longitudinal axis. Optionally, an end reflector may be used to direct the energy in a beam to one side of the fiber end. A reinforcing sleeve for the fiber is mounted to a shielded, Piezo-electric motor constructed and arranged to move the fiber both longitudinally and rotationally within an optional elongate cannula. An MRI system is arranged to generate a series of output signals indicative of temperature in the targeted area. The application of energy is stopped when the temperature at the boundary of the lesion reaches the required hyperthermic temperature. Cooling of the tip portion of the probe is effected by expansion of a supplied cooling fluid through a restrictive orifice into an expansion zone at the probe end. The fiber is encased in a stiff tubular titanium probe with a relatively small fluid supply duct inside the probe with the interior of the probe acting as a return duct for the expanded liquid. The temperature of the probe end is monitored by a sensor in the probe end and controlled by controlling the pressure in the supplied cooling fluid. | 09-25-2014 |
20150087961 | IMAGE-GUIDED THERAPY OF A TISSUE - Image-guided therapy of a tissue can utilize magnetic resonance imaging (MRI) or another medical imaging device to guide an instrument within the tissue. A workstation can actuate movement of the instrument, and can actuate energy emission and/or cooling of the instrument to effect treatment to the tissue. The workstation and/or an operator of the workstation can be located outside a vicinity of an MRI device or other medical imaging device, and drive means for positioning the instrument can be located within the vicinity of the MRI device or the other medical imaging device. The instrument can be an MRI compatible laser probe that provides thermal therapy to, e.g., a tissue in a brain of a patient. | 03-26-2015 |
20150087962 | IMAGE-GUIDED THERAPY OF A TISSUE - Image-guided therapy of a tissue can utilize magnetic resonance imaging (MRI) or another medical imaging device to guide an instrument within the tissue. A workstation can actuate movement of the instrument, and can actuate energy emission and/or cooling of the instrument to effect treatment to the tissue. The workstation and/or an operator of the workstation can be located outside a vicinity of an MRI device or other medical imaging device, and drive means for positioning the instrument can be located within the vicinity of the MRI device or the other medical imaging device.

20150087963 | MONITORING AND NOISE MASKING OF THERMAL THERAPY - Image-guided therapy of a tissue can utilize magnetic resonance imaging (MRI) or another medical imaging device to guide an instrument within the tissue. A workstation can actuate movement of the instrument, and can actuate energy emission and/or cooling of the instrument to effect treatment to the tissue. The instrument can be an MRI compatible laser probe that provides thermal therapy to, e.g., a tissue in a brain of a patient. By tracking a probe position within tissue through feedback, multiple data slices provided around the probe position can be processed to monitor treatment and view thermal data. The operator selects treatment area reference points with the assistance of noise masking. | 03-26-2015 |
20150088108 | PROBE DRIVER - Image-guided therapy of a tissue can utilize magnetic resonance imaging (MRI) or another medical imaging device to guide an instrument within the tissue. A workstation can actuate movement of the instrument via a probe driver, and can actuate energy emission and/or cooling of the instrument to effect treatment to the tissue. The workstation and/or an operator of the workstation can be located outside a vicinity of an MRI device or other medical imaging device, and drive means for positioning the instrument can be located within the vicinity of the MRI device or the other medical imaging device. The instrument can be an MRI compatible laser probe that provides thermal therapy to, e.g., a tissue in a brain of a patient. The probe driver allows for precise positioning, stabilization and manipulation of a probe. | 03-26-2015 |
