In one aspect, embodiments relate to a system for preventative dental laser treatment that ensures even irradiation of a laser beam. The system includes, a laser arrangement configured to generate the laser beam. The laser beam has one or more of a super-Gaussian energy profile and a transverse ring mode. The system also includes a focus optic. The focus optic is configured to converge the laser beam with a numerical aperture of 0.1 or less to a focal region. The system also includes a hand piece configured to direct the laser beam at a surface of a dental hard tissue. The system additionally includes a controller. The controller is configured to control one or more parameters of the laser source, such that a portion of the surface of the dental hard tissue is heated to a temperature in a range between 400° Celsius and 1300° Celsius.

A system that compensates for movement during a surgical procedure on a patient includes a lidar array and a processor. The surgical procedure operates according to a surgical plan. The lidar array tracks the movement of the patient, a medical instrument, and/or a medical professional during the procedure. The processor modifies the surgical plan to compensate for one or more of the movements.

In one aspect, embodiments relate to a system for performing preventative dental laser treatment. The system includes, a code reader configured to read a machine readable code, a processor configured to verify the machine readable code and prevent future verification of the machine readable code, and a laser treatment system configured to perform a laser treatment, based upon the verified machine readable code. The laser treatment system includes a laser arrangement configured to generate a laser beam, an optical arrangement configured to direct the laser beam toward a dental hard tissue, and a laser controller configured to control a parameter of the laser beam in order to heat at least a portion of a surface of the dental hard tissue to a temperature above 400° Celsius.

A method and system for increasing safety of cardiac ablation procedures comprises a computer based system that monitors the esophageal temperature, and a fluoroscopy (medical images) based cardiac mapping system for cryoballoon or radiofrequency (RF) ablations. The esophageal temperature is monitored utilizing an esophageal probe which may have any number of temperature sensing members. The esophageal probe may also have pre-formed shape. During atrial fibrillation ablations, based on a pre-determined increase in esophageal temperature (from any thermistor), the computer based system activates different levels of alarm(s), and/or initiates ablation energy interrupt based on pre-defined programmed values. The method and system is also used for guiding placement of cryoballoon and performing cryoablations. The placement of cryoballoon catheter or a circular catheter is based on superimposing a high resolution (dye injected) image and a live fluoroscopy image and adjusting transparency between the two images.

The illustrated embodiments include an apparatus to reduce or eliminate full thickness injury in tissue and to deform tissue which includes a probe or mechanism for deforming tissue, and a subsystem for selectively cooling and/or heating tissue while deformation is of the tissue is being performed. The illustrated embodiments of the invention also extend to a method to reduce or eliminate full thickness injury in tissue and to deform tissue including the steps of deforming tissue, and selectively cooling and/or heating tissue while deformation of the tissue is being performed.

A nozzle device (1) comprises a plurality of multi-fluid nozzles (5) and a body (2) with a bore (8). The bore (8) has a laser entrance (82) and a laser exit (81). The nozzle device (1) is adapted to be mounted to a laser medical device such that a laser beam generated by the laser medical device enters the laser entrance (82) of the bore (8) of the body (2) and exits the laser exit (81) of the bore (8) of the body (2). The body (2) houses the multi-fluid nozzles (5) and the multi-fluid nozzles (5) are arranged around the laser exit (81) of the bore (8) of the body (2). The nozzle device (1) allows to conditioning a tissue at and near where it is cut or drilled by the laser beam of the laser medical device. Thus, the nozzle device (1) is particularly suitable for a laser osteotomic device allowing to minimize collateral damages of the tissue when being cut or drilled.

A method and apparatus are disclosed for preventing injury to an esophagus caused by heat or cold being delivered to the left atrium, the method including altering a heat exchange device from an insertable configuration to a heat exchanging configuration which has an inflated generally flattened cross section (e.g. capsule-shaped, elliptical) corresponding with the cross section of the inside of the esophagus such that the esophagus is maintained in its natural shape and location. In some embodiments the heat exchange device has a heat exchanger which is inflated to be in the heat exchanging configuration.
