Abstract: A method includes obtaining a first physiological parameter indicative of a non-invasively measured airway pressure of a subject, obtaining a second physiological parameter indicative of a non-invasively measured air flow into the lungs of the subject, and estimating a third physiological parameter indicative of an intra-pleural pressure of the subject based on the first and second physiological parameters and generating a signal indicative thereof. An other method includes obtaining a first physiological parameter indicative of a non-invasively estimated intra-pleural pressure of a subject, determining a second physiological parameter indicative of a lung volume of the subject that is based on a third physiological parameter indicative of a non-invasively measured air flow into the lungs of the subject, and determining a work of breathing based on the first and second physiological parameters and generating a signal indicative thereof.

Abstract: A medical modeling system and method predict a risk of a physiological condition, such as mortality, for a patient. Measurements of a plurality of predictive variables for the patient are received. The plurality of predictive variables are predictive of the risk of the physiological condition. The risk of the physiological condition is calculated by applying the received measurements to at least one model modeling the risk of the physiological condition using the plurality of predictive variables. The at least one model includes at least one of a hidden Markov model and a logistic regression model. An indication of the risk of the physiological condition is output to a clinician.

Abstract: A crutch includes a base, one or more leg support members coupled to the base, and an axillary support member coupled to the base. The leg support members are configurable to at least partially the weight of a person through the person's leg. The axillary support member is configurable to extend under one of the user's arms to at least partially bear weight of the person. The axillary support member may be adjustable to reversibly transform the crutch between axillary support of the person and leg support of the person. The crutch can be selectively configured for use in a hands-free walking mode, an axillary support mode, a sitting mode, or a compact mode.

Abstract: The current invention provides novel nitinol alloys, particularly, nitinol alloys containing a third metallic element referred to as ternary nitinol alloys. Accordingly, the current invention provides nitinol alloys including, but not limited to, Nickel-Titanium-Chromium (NiTiCr) and Nickel-Titanium-Tantalum (NiTiTa). The current invention also provides implants manufactured from the ternary nitinol alloys. The implants comprise the ternary nitinol alloys and are, optionally, surface treated to promote anti-thrombogenicity and biocompatibility, for example, through magnetoelectropolishing (MEP). Accordingly, the current invention provides nitinol alloys and implants comprising the nitinol alloys that reduce the risk of clotting due to stagnant blood flow, eliminate flushing, and minimize infection and damage to blood vessels.
