Patent number: 9877787Abstract: A needle holder for use in an image guided intervention procedure. The needle holder includes a clip for holding a needle and a guide arrangement for supporting the clip and directing the needle at a desired angle relative to a patient's body. The clip includes a releasable connection such that the needle can be disengaged from the guide arrangement by a lateral movement of the clip and/or the guide arrangement relative to the longitudinal axis of the needle.Type: GrantFiled: June 16, 2014Date of Patent: January 30, 2018Assignee: NEORAD ASInventors: Knut Brabrand, Nicolay Berard-Andersen, Gjermund Fjeld Olsen, Vegard Bakke

Patent number: 8814793Abstract: A respiration monitor comprises a transducer array 5 having a plurality of individual transducer elements 7 that span at least part of the region of diaphragm movement of a patient. A patient 1 having a lung 2 and an abdomen 3 being separated therefrom by a diaphragm 4 is fitted with an ultrasound transducer array 5 over the lung sinus 6 prior to being given a CT or MRI scan. Each individual transducer element 6 emits an ultrasound pulse and then detects its echo in the known manner. Because air has a much higher acoustic impedance than tissue, the reflection of the ultrasound beam is much more pronounced when the lung is insonated. By measuring the strength of the receiving signal, it is possible to determine to a high degree of accuracy the position of the patient's diaphragm.Type: GrantFiled: December 3, 2003Date of Patent: August 26, 2014Assignee: Neorad ASInventor: Knut Brabrand

Patent number: 7801583Abstract: Ultrasound Doppler probe 2 is placed above the vein downstream of the infusion site. Processor 4 converts the output from the probe 2 into a form that may be displayed as an image on display unit 5. It also determines whether the velocity corresponds to a flow of contrast medium along the vein. If the cannula 13 is properly sited and the contrast medium flows as desired along the vein, this will lead to an increased flow velocity in the vein. This is detected by ultrasound probe 2 and, as described above, the processor unit 4 will therefore determine that no extravasation has occurred. However, where extravasation of contrast medium occurs this results in a low or zero velocity output from the probe 2 from which the processor unit 4 determines that extravasation has occurred. It therefore immediately sends a “stop” signal to pump controller 11 which stops pump 10.Type: GrantFiled: December 10, 2003Date of Patent: September 21, 2010Assignee: Neorad ASInventor: Knut Brabrand

Patent number: 6443960Abstract: An apparatus for assisting percutaneous light beam guided biopsy, having means for rotating a laser device about first and second rotation axes, the laser device providing its laser beam along an axis intersecting an intersection point between the first and second rotation axes and at right angles thereto. Inclinometers are installed for providing signal values as a function of two- or three-dimensional orientation directions of the said laser device relative to direction of gravitation. Encoding means provide feedback of rotary position information of the laser device. Comparing means compare set calculated instrument insertion angle values, provided from an input device, with encoder feedback signals and inclinometer signals and inhibits rotation operation of the laser device upon reaching specific threshold values.Type: GrantFiled: February 15, 2001Date of Patent: September 3, 2002Assignee: NeoRad A/SInventors: Knut Brabrand, Ole Henrik Eriksen, Ørjan Låg, Jan Martin Bendiksen, Dag Almar Hansen, Steinar Småstuen

Patent number: 6334067Abstract: A method and an apparatus for assisting percutaneous computed tomography-guided surgical activity inside a human or animal body, such as withdrawal of body tissue or body liquid sample, withdrawal of excess body liquid, insertion or injection, said method for determining insertion depth, transversal insertion angle and craniocaudal insertion angle for a needle-type surgical instrument to be inserted into the human or animal body from an insertion entry point on a skin surface of said body to a target inside said body. From a first tomography image coordinate values of said entry point are determined, and from said first or a second tomography image coordinate values of said target point are determined. Based on said coordinate values values of said insertion depth, transversal insertion angle and craniocaudal insertion angle are calculated.Type: GrantFiled: January 19, 2000Date of Patent: December 25, 2001Assignee: Neorad A/SInventor: Knut Brabrand
