A fiducial is generated on an internal anatomical structure of the eye of a patient with a surgical laser. A toric artificial intraocular lens (IOL) is positioned so that a marker of the toric IOL is in a predetermined positional relationship relative to the fiducial. This positioning aligns the toric IOL with the astigmatic or other axis of the eye. The toric IOL is then implanted in the eye of the patient with high accuracy.

A medical device deployment system includes a main body and a guidewire capable of being passed through the main body and including a lumen. An optical shape sensing (OSS) system is configured to pass through the lumen in the guidewire. The OSS system is configured to measure shape, position or orientation of an endograft relative to a blood vessel for placement of the endograft.

The present invention provides methods and devices for controlling a cold slurry that is delivered to a target tissue and for limiting heat transferring from surrounding tissue to the target tissue. In particular, a balloon structure is deployed at or near a point of delivery to act as a physical and/or thermal barrier. In some instances, the balloon structure can act as a pressure device obstructing the flow of warm blood into a treatment area, which can melt the cold slurry.

A surgical system according to one or more embodiments may include: manipulators respectively supporting an endoscope and first and second surgical instruments; a remote control apparatus including a display device, a first operation handle for right hand to operate the first surgical instrument, and a second operation handle for left hand to operate the second surgical instrument; and a control apparatus. The control apparatus may display, on the display device, a graphical user interface, overlapped with the image captured by the endoscope, the graphical user interface including a first area that displays information on the first surgical instrument to be operated by the first operation handle, a second area that displays information on the second surgical instrument to be operated by the second operation handle, and a third area that displays information on the endoscope, which are arranged side by side in order from right to left.

A system may comprise a first catheter having a first steerable segment and a second catheter disposed within the first catheter. The second catheter may have a second steerable segment. The system may also comprise an imaging element supported at a distal end of the second catheter, a coil reference sensor supported at a distal portion of the second catheter, and a processor in electrical communication with the coil reference sensor. The processor may be configured to determine a position of a distal portion of the first catheter with reference to the coil reference sensor.

The present disclosure provides a medical device and method to determine proper implant screw sizing for inserting within the intramedullary canal of a patient's bone. The medical device includes a radiolucent base that includes radiopaque markings indicative of an implant screw. The markings therefore appear on a radiographic image taken of the provided medical device. The markings may include first diameter markings and length markings, and may also include second diameter markings. The first and second diameter markings may be indicative of a major and minor diameter of an implant screw, respectively. The markings may also include an indication of a type or model of implant screw. In some instances, the medical device may include multiple sets of markings. In such instances, each set of markings is indicative of a different implant screw.

A method for creating a patient-specific surgical plan includes receiving one or more pre-operative images of a patient having one or more infirmities affecting one or more anatomical joints. three-dimensional anatomical model of the one or more anatomical joints is created based on the one or more pre-operative images. One or more transfer functions and the three-dimensional anatomical model are used to identify a patient-specific implantation geometry that corrects the one or more infirmities. The transfer functions model performance of the one or more anatomical joints as a function of anatomical geometry and anatomical implantation features. surgical plan comprising the patient-specific implantation geometry may then be displayed.

The present disclosure relates to devices, systems and methods for subdermal tissue tightening through soft tissue coagulation and for use in cosmetic surgery applications. The devices, systems and methods of the present disclosure may be used for a minimally invasive application of plasma energy to subcutaneous tissue for the purpose of tightening lax tissue. The present disclosure further provides tissue tightness measurement devices, systems and methods, which are used to determine the tightness of tissue. The measurements obtained by the tissue tightness measurement devices and/or systems are used to determine when a desired tissue tightness has been achieved during a tissue tightening procedure.

The invention relates to a marker element for marking body tissue. The marker element has an at least approximately rotation-symmetric geometry about a longitudinal axis, is formed by interlinked, elastic and preformed wire members and can assume a radially compressed and a radially expanded state. The wire members are interlinked at their respective ends, preferably in pairs.

A medical device and a method of using same are provided. The medical device includes a first arm and a second arm mounted on a support rail, each of the first arm and the second arm having a bone contacting region. The medical device also includes a mechanism for reducing a distance between the bone contacting regions hereby applying a force to a bone or bones positioned therebetween and a force gauge for indicating a force applied by the bone contacting regions.
