Abstract: An insertable catheter device includes a shaft including a proximal end and a distal end, an expandable balloon, and an actuator configured to expand and retract the expandable balloon. The actuator includes a fluid conduit that extends through the shaft and is coupled with the expandable balloon to enable inflation and retraction of the expandable balloon via injection or withdrawal of a fluid to or from the expandable balloon via the fluid conduit. The expandable balloon is displaceably retractable into the shaft and extendable from the shaft. A fluid pump is coupled with the fluid conduit to pump the fluid through the fluid conduit. A patch is positioned to be displaced by the expandable balloon when the expandable balloon is inflated, and the expandable balloon is displaceably retractable into the shaft and displaceably extendable from the shaft.

Abstract: Methods and systems for detecting overstride in runners include measuring, using an inertial measurement unit affixed to a shank of a person, an acceleration and an angle of the shank during a stride, monitoring, using a microprocessor, the shank acceleration measurements to detect an acceleration profile indicative of the corresponding foot making initial contact with the ground during the stride, determining, using the microprocessor, the corresponding shank angle at initial contact from the shank angle measurements, comparing, using the microprocessor, the shank angle at initial contact to a threshold shank angle, and identifying, using the microprocessor, an overstride of the corresponding leg if the shank angle at initial contact exceeds the threshold shank angle.

Abstract: A multi-segment reinforced actuator includes (a) a soft actuator body that defines a chamber and (b) a plurality of distinct reinforcement structures on or in respective segments of the soft actuator body. First and second reinforcement structures are respectively configured to produce a first and second actuation motions, respectively, in first and second segments of the soft actuator body when fluid flows into or out of the chamber. The actuation motions are selected bending, extending, expansion, contraction, twisting, and combinations thereof; and the first actuation motion differs from the second actuation motion. The actuator can be used, e.g., to facilitate bending of the thumb with corresponding bending, extending, expansion, contraction, and twisting actuation motions.

Abstract translation: 多段增强致动器包括（a）柔性致动器主体，其限定腔室和（b）柔性致动器主体的相应部分上或其中的多个不同的加强结构。 第一和第二加强结构分别构造成当流体流入或流出腔室时，分别在软致动器主体的第一和第二段中产生第一和第二致动运动。 致动运动被选择为弯曲，延伸，膨胀，收缩，扭转及其组合; 并且第一致动运动与第二致动运动不同。 可以使用致动器，例如，以便于拇指以相应的弯曲，延伸，膨胀，收缩和扭转致动运动弯曲。
