Abstract: The present invention relates to substrates and composites having dynamic, reversible micron-level luminal surface deformation including texture or geometric instabilities, e.g., surface wrinkling and folding. The surface deformation and its reversal to the original surface form or to another, different surface form, is effective to reduce or prevent surface fouling and, more particularly, in certain applications, to reduce or prevent unwanted platelet adhesion and thrombus formation. The substrates and composites include a wide variety of designs and, more particularly, biomedical-related designs, such as, synthetic vascular graft or patch designs.

Abstract: A system for prescribing insulin doses is provided, wherein a first titration application component structured to is implemented on a patient computing device of the patient, wherein the first titration application component logs glucose level data measured from the patient and insulin dose data indicative of a number of insulin doses given to the patient. The system includes a provider computing including a second titration application component, wherein the second titration application component is structured and configured to receive the glucose level data and the insulin dose data from the patient computing device, determine a correction factor based on a sensitivity constant specified by the healthcare provider, and determine the insulin dose recommendation for the patient based on the insulin dose data, the glucose level data and the correction factor, wherein the provider computing device is structured and configured to transmit the insulin dose recommendation to the patient computing device.

Abstract: Disclosed cannula systems can detect the tissue type within which the cannula tip is located in real time using electrodes adjacent the cannula tip. The sensing cannula system can differentiate when the cannula tip is in adipose tissue or muscle based on electrical impedance. The system can be used in fat grafting and liposuction procedures, for example. An operator can detect if the cannula tip enters muscle by watching for an indicator light or audible alarm that is automatically activated by the device based on a change in sensed impedance. The device may also stop the flow of fat through a pump halting injection into the sub-muscular space.

Abstract: Disclosed herein are endotracheal tubes that have multiple inflatable cuffs to help form a seal for ventilation, to reduce unwanted migration of the tube relative to the patient, reduce focalized pressure from a single cuff, and to help prevent aspiration of materials between the outside of the tube and the tracheal walls. Some devices include first and second distal cuffs for placement within the trachea and a proximal third cuff for blocking the entrance to the trachea. The cuffs can include ridges or textures to enhance sealing. The device can also include inflation channels, vacuum channels, and pressure sensors.

Abstract: A computer-based workflow management method is provided for use in connection with a process for printing an object with a three-dimensional printer. The method includes executing a request queue phase comprising receiving instructions for defining a request for printing the object; executing an anatomic modeling phase comprising generating an anatomic three-dimensional model representing the object; and executing a build phase comprising printing an object in response to the generated anatomic model. The method includes generating and displaying various user interface screens programmed for visualizing different aspects of phases or stages of the three-dimensional printing process.

Abstract: Disclosed herein are endotracheal tubes that have external baffles near the distal end of the tube to reduce unwanted migration of the tube relative to the trachea and to help prevent materials from passing between the outside of the tube and the tracheal walls. The baffles can be made of soft flexible material that conforms to and seals against the trachea. The baffles can be angled proximally or distally, or both. The baffles can be tapered in thickness and can vary in radial length. Some embodiments can include a supraglottic umbrella. Some embodiments can include an axially expandable portion along the tube. Some embodiments can include a loading tube that helps set the deflection orientation of the baffles within the trachea.

The arm and attachable tools can be detachable, disposable and/or sterilizable, while other system components can remain mounted in a fixed location as the arm is removed and replaced. The arm can hold multiple tools in any desired orientation around subject work location.
