Abstract: This invention provides a nasal guard, which can be constructed according to various manufacturing techniques (e.g. molding. 3D printing, etc.) for use during nasal sinus and skull base surgery to reduce aerosolized transmission to protect surgical staff, conserve the volatile supply of personal protective equipment (PPE) and reduce the introduction of particles into the operating room. The novel nasal guard, according to embodiments of this invention, can be readily applied to the patient's nose/nasal region during surgery and, while exposing the nostrils for access by surgical procedures, reduces aerosol emission from the nares. This allows for an adequate seal on a variety of face sizes/shapes without impeding access for surgical tools and/or does not otherwise interfere with surgical approach. The nasal guard herein is also compatible with standard suction equipment. The nasal guard is easy-to-use and ergonomic, and can be (is) constructed from biocompatible materials.

Abstract: A method for cardiovascular-dynamics correlated imaging includes receiving a time series of images of at least a portion of a patient, receiving a time series of cardiovascular data for the patient, evaluating correlation between the time series of images and the time series of cardiovascular data, and determining a property of the at least a portion of a patient, based upon the correlation. A system for cardiovascular-dynamics correlated imaging includes a processing device having: a processor, a memory communicatively coupled therewith, and a correlation module including machine-readable instructions stored in the memory that, when executed by the processor, perform the function of correlating a time series of images of at least a portion of a patient with a time series of cardiovascular data of the patient to determine a property of the at least a portion of a patient.

Abstract: A system and method for creating a cavity with a drill assembly provides a powered drill shaft assembly having an articulating tip and a position sensor along the drill shaft; a drill motor assembly with a rotational motor, linear actuator, torque sensor, rotation sensor, electrical resistance sensor and a controller unit having a plurality of programs providing user interface and controlling the operation of the powered drill arrangement; a shroud for the drill shaft with a water port; and a computer software package that combines user specifications with sensor data to control activation and displacement of the drill with a user interface, controls the motor for rotational speed and drilling depth, and gives sensor status, and a display displaying status of a drilling procedure and an image from an imaging device, and that is programmable for a set of parameters for a drilling procedure.

Abstract: A support rig for a medical instrument can hold a medical instrument that is inserted into a patient in a fixed position and orientation relative to patient, so that the position and orientation of the medical instrument is not affected by the breathing or other motion of the patient. The support rig and medical instrument can be radiolucent and non-metallic, so that an image can be taken of the patient while the medical instrument is inserted in the patent and held by the support rig. The radiolucent support rig and medical instrument can allow for imaging, including x-ray, CT, and/or MRI, to occur simultaneously during the surgery. Surgical outcomes can be improved by using imaging to provide information about a tumor and/or anatomical structures during surgery.

Abstract: This invention provides a system and method that employs multiple measurements of various, relevant tissue states of a patient to detect and predict OH and similar conditions. These multi anatomic measurements are transformed by a multivariate algorithm to outputs that convey the diagnostic and prognostic risk of the disease of interest. This novel, multiple-measurement technique avoids use of a single measurement, which is generally unlikely to adequately extract sufficient information to drive a clinically useful test in the setting of complex system disease. The system and method herein thereby allows automated monitoring of currently stable patients who, are known or suspected to have OH and/or similar internal conditions on a substantially continuous basis.
