20110006212 | DETECTING PHOTONS IN THE PRESENCE OF A PULSED RADIATION BEAM - A detector system adapted for monitoring a radiation treatment system comprising a pulsed beam radiation source for treating a body with a given beam intensity and beam configuration, with pulse times and intervals between pulses less than 100 milliseconds, using at least one monitoring radiation source located inside or outside the body, the detector system comprising; a) a detector designed to detect radiation from the monitoring source, and subject to interference radiation from the beam source; and b) control circuitry that creates a data record of radiation received by the detector, to provide information about the body; wherein, when the detector detects radiation in real time during operation of the beam, the data record selectively excludes data for radiation received by the detector during the pulses, as opposed to data for radiation received by the detector between pulses. | 01-13-2011 |
20110105897 | HYBRID MEDICAL DEVICE LOCALIZATION SYSTEM - A hybrid radioactive and impedance tracking system for tracking a target in a human or animal body, comprising: a) a radioactive tracking subsystem for tracking the target; b) an impedance tracking subsystem for tracking the target; and c) a processor that uses data from the radioactive tracking subsystem in combination with data from the impedance tracking system to estimate a position of the target. | 05-05-2011 |
20110118588 | Combination MRI and Radiotherapy Systems and Methods of Use - A combination MRI and radiotherapy system comprising: a) an MRI system for imaging a patient receiving radiotherapy, comprising a magnetic field source suitable for generating a magnetic field of strength and uniformity useable for imaging, capable of being ramped up to said magnetic field in less than 10 minutes, and ramped down from said magnetic field in less than 10 minutes; b) a radiation source configured for applying radiotherapy; and c) a controller which ramps the magnetic field source down to less than 20% of said magnetic field strength when the radiation source is to be used for radiotherapy, and ramps the magnetic field source up to said magnetic field strength when the MRI system is to be used for imaging. | 05-19-2011 |
20140371786 | EXPANDABLE MEDICAL ANCHOR DEVICE FORMED OF CUT METAL TUBE - A radially expandable anchor device formed of a cut metal tube is described. The tubular wall of the cut metal tube has a plurality of slits thereon, which together form a plurality of bands. The plurality of slits is configured to allow the plurality of bands to splay outward in the form of overlapping petals when an axial compressive force is applied to the cut metal tube. The cut metal tube may have a combination of radial and non-radial cuts. The non-radial cuts allow the adjacent sections of the tubular wall on opposing sides of the cut to overlap each other when they are pressed together by an axial compressive force, thus facilitating the radial expansion of the cut metal tube. | 12-18-2014 |
20150066008 | DEVICE FOR AUTOMATIC ANCHOR UNDEPLOYMENT AND RETRACTION - A tissue closure device and a treatment method for closing an opening in a tissue wall are described. The tissue closure device comprises a heating element and a removable anchor having an anchor shaft and an occluding element at or near a distal end of the anchor shaft. The occluding element of the anchor is configured to be expanded and collapsed. The treatment method comprises introducing the occluding element of the anchor into a body canal through an opening in a tissue wall of the body canal, and deploying the anchor such that the occluding element expands to temporarily occlude the opening in the tissue wall. The tissue region surrounding the opening is then heated to cause shrinkage of collagen-containing tissue, thereby contracting the opening in the tissue wall. When a predefined trigger associated with the treatment method is met, the anchor is automatically undeployed and retracted from the body canal. | 03-05-2015 |
