  • Patent number: 9387042
    Abstract: 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.

  • Patent number: 9333038
    Abstract: 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.

  • Patent number: 7691100
    Abstract: An MRI guided surgical apparatus includes a heat source formed by a laser and an optical fiber carrying the heat energy into a part to be coagulated by hyperthermia with an end reflector to direct the energy in a beam to one side of the fiber end. A reinforcing sleeve for the fiber is mounted in a shielded, Piezo-electric motor which causes movement of the fiber longitudinally and angularly within a rigid elongate cannula. A magnetic resonance imaging system is arranged to generate a series of output signals over a period of time representative of temperature in the part as the temperature of the part changes during that time. The heat source is controlled in heat energy applied and location and orientation of the beam to stop heating when the temperature at the boundary of a tumor reaches the required hyperthermic temperature. Cooling of the tip portion of the probe is effected by expansion of a supplied cooling fluid in gaseous form through a restrictive orifice into an expansion zone at the probe end.

  • Patent number: 7167741
    Abstract: This surgical device uses a laser beam to coagulate tissue. The elongate device carries the beam through an optical fiber that has a chamfered end for deflecting the beam out of a distal end of the device at an angle. Tissue coagulation is monitored using a magnetic resonance imaging system that provides periodic tissue temperature data. A small fluid supply duct provides cooling fluid that expands to a gas near the distal end of the device, thereby cooling the tip.

  • Patent number: 6418337
    Abstract: An MRI guided surgical apparatus includes a heat source formed by a laser and an optical fiber carrying the heat energy into a part to be coagulated by hyperthermia with an end reflector to direct the energy in a beam to one side of the fiber end. The fiber includes a reinforcing sleeve along its length to prevent bending and twisting. The sleeve is mounted in a shielded, Piezo-electric motor which causes movement of the fiber longitudinally of its axis to move the end within the part and rotation of the fiber about its axis to cause the beam to rotate about the axis. A rigid elongate cannula is arranged for insertion to a position at the part of the patient having a bore for receiving a portion of the fiber adjacent the outlet end in sliding engagement therein such that the end can pass through the cannula into engagement with the part of the patient. A part of the sleeve projecting beyond the cannula is rigid and a further part connecting to the motor is stiff but less rigid.

  • Patent number: 5431201
    Abstract: A system for filling containers with a prescribed medication includes a support head for receiving a disposable syringe which allows the syringe to be pumped to transfer liquid to an from the syringe. A robot arm is also provided to carry medication and diluent containers to the syringe for withdrawing diluent to the syringe and injecting it into the medication container for mixing. In order to ensure alignment of the containers with the syringe, there is provided on the support head an additional needle grasping system which grasps and locates the needle for penetration of the membrane of the container. The support head includes a weigh scale as an integral element thereof so that the syringe is weighed after each step of the process.
