Abstract: An example system for estimating an injury risk relating to a fall for a patient can include: at least one processor; and memory encoding instructions which, when executed by the at least one processor, cause the at least one processor to: access first data associated with an estimated likelihood of a fall for the patient; access second data associated with an estimated severity of a fall for the patient; and calculate a score based upon the first data and the second data.

Abstract: An example system for estimating a likelihood of a fall for a patient includes: at least one processor; and memory encoding instructions which, when executed by the at least one processor, cause the at least one processor to: access first data associated with acute action of and environment for the patient; access second data associated with attributes of the patient over time; calculate a composite fall score based upon the first data and the second data.

Abstract: A heat transfer system and method for cryoablation includes a cryo-catheter with a tip, and a temperature sensor mounted at the distal end of the cryo-catheter. A system controller is in electronic communication with both a pressure regulator and the temperature sensor. The system takes advantage of the transfer of latent heat to minimize the tip temperature at the distal end of the cryo-catheter. More specifically, after measuring the temperature at the distal end of the cryo-catheter, and comparing the temperature data and input pressure to a known pressure-temperature curve, the input pressure of the liquid fluid refrigerant may be adjusted. At the correct pressure setting, the liquid fluid refrigerant will begin to boil at the distal end of the cryo-catheter, and the tip temperature will be at a minimum.

Abstract: A system and method for transferring heat requires a supply tube connected in fluid communication with a capillary tube. A tip member is positioned to surround the distal end of the capillary tube to create a cryo-chamber. In operation, a liquid refrigerant is introduced into the supply tube at a working pressure (e.g. 450 psia). The pressure is then significantly reduced on the liquid refrigerant as it transits through the capillary tube. The refrigerant then exits the distal end of the capillary tube, still in its liquid state. Inside the cryo-chamber, at a pressure of less than about one atmosphere, the refrigerant transitions into its gaseous state. The resultant refrigeration causes heat to transfer into the cryo-chamber.
