A removable and replaceable sheath may be coupled to a medical instrument used during a procedure, and may enable one or more functional features of the medical instrument while maintaining a sterile barrier between the instrument itself and the treatment site. The sheath may be replaced prior to a subsequent use, and sterilization of the medical instrument is not required due to the sterile barrier. Sheaths may include an embedded memory that stores procedure configurations and procedure results, longitudinal channels for delivering power or irrigation, optical elements for providing procedure specific endoscopic views, and other features. One sheath may be fitted to an endoscope for imaging and tissue ablation. Another sheath includes a balloon usable during sinuplasty procedures. Yet another sheath may be fitted to a sonic ablation instrument to provide improved transmission of sonic power to tissue.

A method of multimodal scanning may include generating surface scan data of an intraoral structured using structured light. The method may include generating volumetric scan data of an internal structure of the intraoral structure with OCT scanning. The OCT scan data may be aligned with the surface scan data. A three-dimensional volumetric model of the patient's dentition may be generated based on the aligned OCT scan data and the surface scan data.

One aspect of the invention relates to an intubation aid (10). The intubation aid (10) comprises an elongated main part (12), and the intubation aid (10) is provided with an operating device (26). The main part (12) is designed to be curved in a first region (18) of the main part (12), and the main part (12) is additionally designed to be curved in a second region (20) of the main part (12), said second region being separated from the first region (18) and being arranged adjacently to the free end (16) of the main part (12). The main part (12) additionally comprises a positioning device (24) which is designed to limit a translational displacement of a tube (46) placed on the intubation aid (10) in at least one direction. A second aspect of the invention relates to an intubation aid which can be placed on an endoscope.

Systems and methods for visualizing ablated tissue are disclosed. In some embodiments, a system for imaging tissue comprising: a catheter having a distal end and a proximal end; an inflatable balloon disposed about the distal end of the catheter; and an optical housing extending from the distal end of the catheter into the balloon, the optical housing being configured to position inside the balloon a light source for illuminating a tissue outside the balloon and a camera for imaging the illuminated tissue.
