  • Medical device for preparing thermoplastic material
    Patent number: 9513014
    Abstract: A device for preparing a thermoplastic material, with dry heat, for use in patient fixation. The device generates circulated heat to a threshold temperature. Once the thermoplastic material has become pliable, it is molded into a cast for fixation purposes. The circulated heat may be generated by a device having a housing and a support member movably attached to the housing. The device also includes a heating element and an array of circulation elements.
    Type: Grant

Once the thermoplastic material has become pliable, it is molded into a cast for fixation purposes. The circulated heat may be generated by a device having a housing and a support member movably attached to the housing. The device also includes a heating element and an array of circulation elements to push air centrally at the central region and drawing air from a periphery region concurrently.

  • Machinable plastic compensator filter
    Patent number: 6381304
    Abstract: A compensator filter is used to adjust the radiation therapy beam of a linear accelerator device to compensate for tissue that may have been removed surgically. The compensator filter is formed of a plastic material having a density of about one to two times that of the patient's tissue, and is disposed in the filter tray of the linear accelerator for selectively attenuating the radiotherapy beam to compensate for the missing tissue. Preferably, the filter can be made from a blank cast of polyurethane filled with glass microspheres, such that the filter is substantially free of heavy metal substances and toxic materials. The blank can be milled in a compensator filter milling machine of the type that is found in radiotherapy clinics.
