Specifically, because the pull wire facilitates changing a bend angle of the deflectable distal portion of the catheter shaft, the catheter can fit in a wide variety of differently sized nasal cavities and Eustachian Tubes. Optionally, a visualizing distal tip can be positioned distally from the deflectable distal portion of the catheter shaft and include a distally facing camera that can be used to confirm that the deflectable distal portion is properly positioned in the patient.

A virtual endoscopic view shows a surgical area and surrounding anatomy and may also show a position of a surgical instrument in use during a surgical procedure, allowing a surgeon to virtually view the surgical area when direct viewing or actual endoscopic views are incomplete, obstructed, or otherwise unavailable or undesirable. In order to render the endoscopic view, an IGS navigation system may be configured with an observer point and an observer orientation within 3-D space based upon user inputs. A user interface for defining these points allows a user to view a virtual endoscopic preview in real-time while providing inputs, thus improving the likelihood that the resulting virtual endoscopic view is as desired by the user; and reducing time spent redefining and reconfiguring the virtual endoscopic view. The virtual endoscopic preview may provide combinations of static and dynamic images to illustrate the spatial relationship of the provided inputs.

HEMOSTATIC SEALANT POWDER FOR SEALING LEAKS IN TISSUES
Disclosed herein are powdered compositions comprised of fibrinogen, thrombin, glycerol-water solution, and optionally oxidized cellulose (OC), wherein the glycerol is present at a concentration ranging from about 0.7% to about 6%, by weight; and wherein the OC is present at a concentration below about 9%, by weight, or is absent. Methods of making the compositions, and uses of the compositions in methods for treating a bleeding tissue, and for sealing leaks in tissues are further disclosed.
A healthcare system accommodates spasmodic clinical workflows for populating a records database associated with a surgical platform or other digital healthcare platform. An interoperability engine receives data streams including events from various electronic health records systems that provide data events according to varying format, order, and timing dependent on their corresponding clinical workflows. The interoperability engine maps indeterminate events to expected events associated with a clinical workflow based on a clinical workflow management file, an industry standard model, a general parsing model, or a combination thereof. The interoperability engine may furthermore detect non-compliance of received events and may generate feedback indicative of a compliance assessment.

G16H 10/60 - ICT specially adapted for the handling or processing of patient-related medical or healthcare data for patient-specific data, e.g. for electronic patient records
A guide sheath includes ports at a handle portion through which flexible endoscopic tools may be advanced until they emerge from corresponding ports at a distal tip of the guide sheath. The guide sheath includes a position sensor at its distal tip that is compatible with an image guided surgery (IGS) system, such that a virtual view of the distal tip's position relative to a surgical site may be presented by the IGS system. The virtual view may assist a surgeon in precisely positioning the distal tip at the surgical site, and then one or more flexible endoscopic tools may be advanced the length of the guide sheath for use at the surgical site. The guide sheath may also include an articulating portion at the distal tip that may be deflected in one or more directions in order to provide additional control over placement within the surgical site.

A method includes inserting a dilation catheter into a nostril of a patient and positioning a first dilator of the dilation catheter between a turbinate of the patient and an adjacent lateral nasal wall of the patient. The method also includes expanding the first dilator, thereby applying pressure to the turbinate of the patient, and removing the dilation catheter from the nostril of the patient.
A method includes inserting a variable distance electrode assembly within a patient. A first electrode of the variable distance electrode assembly is placed adjacent to a targeted tissue area. A second electrode of the variable distance electrode assembly is placed adjacent to the targeted tissue area such that the first electrode and the second electrode are spaced from each other to define a first distance. The first and second electrodes are activated to apply electrical energy to the targeted tissue area. The first electrode is translated relative to the second electrode to define a second distance between each other while the first electrode and the second electrode continue to apply electrical energy to the targeted tissue area.

Disclosed is a sealant, and techniques for making and using the sealant. The sealant may include three components that, when combined, produce the sealant: an electrophilic component, a nucleophilic component, and a doping component. The electrophilic component may include a first electrophilic material having a first functionality of a first reactive group. The nucleophilic component may include a first nucleophilic material having a second functionality of a second reactive group. The doping component may include a second electrophilic material having a third functionality of the first reactive group greater than the first functionality and/or a second nucleophilic material having a fourth functionality of the second reactive group greater than the second functionality. The doping component may be present in an amount sufficient to provide a 2-20% molar contribution of the first reactive group and/or the second reactive group in the sealant.
