Laser system delivering ultra-short pulses along multiple beam delivery paths
A laser system includes a laser source generating a laser beam having ultra-short pulses; a laser delivery assembly optically receiving the laser beam and comprising: a beam splitter configured to split the laser beam between a first beam delivery path and a second beam delivery path; and at least one focusing lens optically coupled to the beam splitter and configured to focus the laser beam from each of the first beam delivery path and the second beam delivery path to a focal point on a predefined plane; wherein the first beam delivery path intersects the predefined plane at a first angle, the second beam delivery path intersects the predefined plane at a second angle, and a first pulse from the first beam delivery path and a second pulse from the second beam delivery path are coincident at the focal point.
High speed corneal lenticular incision using a femtosecond laser
An ophthalmic surgical laser system and method for forming a lenticule in a subject's eye using “fast-scan-slow-sweep” scanning scheme. A high frequency scanner forms a fast scan line, which is placed by the XY and Z scanners at a location tangential to a parallel of latitude of the surface of the lenticule. The XY and Z scanners then move the scan line in a slow sweep trajectory along a meridian of longitude of the surface of the lenticule in one sweep. Multiple sweeps are performed along different meridians to form the entire lenticule surface, and a prism is used to change the orientation of the scan line of the high frequency scanner between successive sweeps. In each sweep, the sweeping speed along the meridian is variable, being the slowest at the edge of the lenticule and the fastest near the apex.
Automated surgical robot
An automated laser-surgery system for performing a closed-loop surgical procedure is disclosed. The procedure includes forming a post-procedural goal based on a three-dimensional (3D) image of a surgical site, planning a path for a surgical laser signal based on the post-procedural goal, performing a procedural pass by steering the surgical laser signal along the path, measuring the surface of the surgical site after the procedural pass, updating a model based on the measured effect at the surgical site, and evaluating the success of the procedural pass based on the surface measurement and the post-procedural goal. If necessary, a new path is planned based on the post-procedural goal and the surface measurement a new pass based on that path is performed, and the surface is again measured to evaluate the success of the new pass. These operations are repeated as a closed-loop sequence as many times as necessary to achieve success.
LASER SYSTEM DELIVERING ULTRA-SHORT PULSES ALONG MULTIPLE BEAM DELIVERY PATHS
A laser system includes a laser source generating a laser beam having ultra-short pulses; a laser delivery assembly optically receiving the laser beam and comprising: a beam splitter configured to split the laser beam between a first beam delivery path and a second beam delivery path; and at least one focusing lens optically coupled to the beam splitter and configured to focus the laser beam from each of the first beam delivery path and the second beam delivery path to a focal point on a predefined plane; wherein the first beam delivery path intersects the predefined plane at a first angle, the second beam delivery path intersects the predefined plane at a second angle, and a first pulse from the first beam delivery path and a second pulse from the second beam delivery path are coincident at the focal point.
Feedback detection for a treatment device
A system includes a focus optic configured to converge an electromagnetic radiation (EMR) beam to a focal region located along an optical axis. The system also includes a detector configured to detect a signal radiation emanating from a predetermined location along the optical axis. The system additionally includes a controller configured to adjust a parameter of the EMR beam based in part on the signal radiation detected by the detector. The system also includes a window located a predetermined depth away from the focal region, between the focal region and the focus optic along the optical axis, wherein the window is configured to make contact with a surface of a tissue.
TRANS-ORAL SURGERY DEVICE COMPRISING A BLADE WITH A DISTAL SCAFFOLD AND A SUPPORT ADJUSTABLE THROUGH TENDONS
A trans-oral surgery device has a scaffold insertable into the vicinity of the larynx or hypopharynx of a subject. A support is arranged for holding a flexible optical fiber for delivering light to the subject. A plurality of tendons is connected to the support, and slidably anchors the support to the scaffold. The tendons are adjustable to move the support relative to the scaffold. The scaffold is provided at the front end of a blade, and the blade is non-straight.
METHOD FOR MEASURING PATIENT-SPECIFIC TEMPOROMANDIBULAR JOINT RELATION AND TRANSFERRING IT INTO A VIRTUAL ARTICULATOR
The present invention relates to method of measuring patient-specific temporomandibular joint relation and transferring it into a virtual articulator (2) by using, a device (1) comprising: a transfer linkage (3) which can be attached from its upper end to a ace bow (4); an impression means (5) for bolding impression material (6) and for taking the impression of the upper jaw and/or the lower jaw of the patient through said impression material (6); at least a first form-fitting component (7) fixed at the lower end of the transfer linkage (3), for leaving an impression (8) on the impression material (6) to be placed on the grip (9) of the impressions means (5) projecting out of the mouth of the patient.
SYSTEMS AND METHODS FOR LASER-ASSISTED TOPICAL TREATMENT OF NAIL FUNGAL INFECTIONS
Systems and methods for a laser-assisted topical treatment of nail fungal infections are provided. The laser-assisted topical treatment includes a laser that is configured to output a beam that penetrates the infected nail and creates a channel therethrough. The laser-assisted topical treatment further includes a treatment agent comprising a vehicle and a drug. The treatment agent is applied to an exterior surface of the infected nail so that the treatment agent may flow into the channel.

METHODS AND APPARATUS FOR REMOVAL OF SKIN PIGMENTATION AND TATTOO INK
Methods and apparatus for dermatological laser treatment, e.g. for the removal of unwanted tattoos or other skin pigmentation. Removal of multiple colors with a single pulsed laser beam may be achieved using intensities in excess of about 50 GB/cm.sup.2. Methods for reducing the pain and tissue damage associated with laser tattoo removal include using a spot size of less than 2 mm with a fluence in the range of 0.5-10 J/cm.sup.2. Scanning the laser beam over an area of skin to be treated allows such areas to be treated accurately with scanning patterns calculated to promote rapid dissipation of heat away from treated portions of the skin. Multiple treatment rooms may be served by a single pulsed treatment laser by beam toggling, splitting or pulse-picking to minimise downtime of the laser.
