Publication number: 20140128881Abstract: 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.Type: ApplicationFiled: March 15, 2013Publication date: May 8, 2014Applicant: Monteris Medical Inc.Inventors: Richard Tyc, Salman Qureshi, Mark Andrew Grant, Luis Filipe Silva Fernandes, Daniel Prazeres Carreira, John Schellhorn

Publication number: 20130006230Abstract: 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.Type: ApplicationFiled: August 31, 2012Publication date: January 3, 2013Applicant: MONTERIS MEDICAL, INC.Inventors: Mark G. Torchia, Richard Tyc, John S. Pacak, Ken J. McTaggart

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.

Patent number: 7691100Abstract: 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.Type: GrantFiled: August 25, 2006Date of Patent: April 6, 2010Assignee: Monteris Medical, Inc.Inventors: Mark G.

Publication number: 20100042112Abstract: A drive system for controlling movement of an elongate member includes a base unit having a first rotatable knob and a second rotatable knob, a follower assembly including a follower slidably coupled to a guide rail, a longitudinal movement wire, and a rotational movement wire. The follower includes a longitudinal movement pulley, a rotational movement pulley, and an alignment element structured to receive an elongate member such that the elongate member is attachable thereto. The longitudinal movement wire operably couples the first rotatable knob to the longitudinal movement pulley such that rotation of the first knob drives the follower in a longitudinal direction along the guide rail. The rotational movement wire operably couples the second rotatable knob to the rotational movement pulley such that rotation of the second knob rotates the alignment element and attached elongate member.Type: ApplicationFiled: August 13, 2009Publication date: February 18, 2010Applicant: Monteris Medical, Inc.Inventors: Salman Qureshi, Mark Grant, Luis Filipe Silva Fernandes

Patent number: 7167741Abstract: 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.Type: GrantFiled: December 14, 2001Date of Patent: January 23, 2007Assignee: Monteris Medical, Inc.Inventors: Mark G.
