Abstract: An active prosthetic socket including a prosthetic socket shaped to fit a residual limb. An active adjustment system is integrated with the prosthetic socket and is configured to dynamically adjust the fit of the active prosthetic socket to the residual limb of a user during ambulation or motion.

Abstract: A flow rate sensor system for non-invasively measuring the flow rate of a bodily fluid. The system includes an encapsulated implant having a flow tube having an inlet and an outlet configured to receive a flow of a bodily fluid. A heating element externally coupled to the flow tube is configured to dissipate heat at a predetermined rate over a predetermined amount of time. A temperature sensor externally coupled to the heating element is configured to measure a temperature rise of the heating element over the predetermined amount of time. An implant microcontroller coupled to the temperature sensor is configured to determine the flow rate of the bodily fluid in the flow tube from the measured temperature rise and a curve fit to a stored set of previously obtained calibration measurements. An implant power and communication subsystem is coupled to the implant microcontroller configured to wirelessly receive power and wirelessly transmit and receive data.

Abstract: A two-stage system for oxygenating and removing carbon dioxide from a physiological fluid, including: a primary exchange module configured to receive a gas having oxygen therein and a carrier fluid having carbon dioxide therein. The primary exchange module is configured to transfer oxygen from the gas to the carrier fluid and transfer carbon dioxide from the carrier fluid to the gas to create an oxygen loaded carrier fluid and a carbon dioxide load gas. A secondary exchange module is configured to receive the oxygen loaded carrier fluid and a physiological fluid having the carbon dioxide therein. The secondary exchange module is configured to transfer the oxygen from the oxygen loaded carrier fluid to the physiological fluid and transfer carbon dioxide from the physiological fluid to the carrier fluid to create an oxygen loaded physiological fluid.

Abstract: A steerable delivery system with a steerable section rigid along its longitudinal axis and flexible in at least one direction off-axis and a follower section rigid along its longitudinal axis and flexible in at least the same direction as the steerable section, both the steerable section and the follower section advanceable in the direction of the longitudinal axis. A pivot member is disposed between a proximal end of the steerable section and a distal end of the follower section. A steering mechanism is located on the proximal end of the follower section for actively flexing the steerable section at the pivot member, and steering the steerable section in said one direction, the follower section flexing to follow the steerable section.
