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.

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.

The invention relates to biodegradable bilayer sealants for tissue closure. The sealants of the invention are composed of two layers with different compliances. The layer in immediate contact with the tissue has high compliance. The second layer located immediately above the first sealant layer has low compliance, i.e. the sealant is much stiffer. The burst pressure of the bilayer sealants is enhanced relative to either a single layer elastic sealant or a single layer stiff sealant. The improved sealant compositions herein provide a water-tight seal, can access hard to reach tears, be applied in a dry or wet environment, are low-swelling, and can repair a range of incision or tear sizes. The bilayer sealants are particularly useful for sutureless dural closure or as adjuncts to sutured dural closure. Also provided herein are methods of preparing and using the biodegradable sealant compositions.

A method of treating a patulous Eustachian tube includes forming a first pocket in a wall of a nasopharynx region proximate to a pharyngeal ostium, inserting a resiliently biased implant within the first pocket, and allowing the resiliently biased implant to expand within the first pocket to thereby urge the Eustachian tube towards a closed state. The wire implant may include a resilient stent or other resilient wire structure. In some versions, a deployment device having a balloon is used to deploy a malleable implant. This deployment device has a malleable implant disposed around the balloon, which is disposed around a guide catheter. The balloon is inflated and expands the malleable implant. The malleable implant retains the expanded shape and urges the Eustachian tube toward a closed state.

Methods and Devices for Changing the Flow Rates of PH Modifying Fluids for Controlling Cross-Linking Rates of Reactive Components of Biocompatible Sealing Compositions
A method of making a biocompatible composition for sealing tissue includes mixing a first fluid having a first reactive component (e.g., an electrophile) and a second fluid having a second reactive component (e.g., a nucleophile) to form a mixture and expressing the mixture. During expression, a pH modifying fluid (e.g., NaOH) is added to the mixture at a rate that changes. In one embodiment, a higher ratio of the pH modifying fluid is added to the mixture during a first expressing stage and a lower ratio of said pH modifying fluid is added to the mixture during a second expressing stage. During the first expressing stage, a mixing ratio of the pH modifying fluid, the first fluid and the second fluid is 0.7-1.4:1:1. During the second expressing stage, the mixing ratio of the pH modifying fluid, the first fluid and the second fluid is 0.12-0.24:1:1.
