Abstract
A system for augmenting uterine forces includes a medical apparatus having a balloon body that transitions between a compacted state and an expanded state, a catheter that receives the medical apparatus and obtains electrical signals indicative of intrinsic uterine contractions, and a controller coupled to the catheter to receive the electrical signals, and to a source of an agent. The controller processes the electrical signals to detect an onset of an intrinsic uterine contraction, an increase in uterine contraction forces, or a decrease in uterine contraction forces. In response to a detection of an onset of an intrinsic uterine contraction or an increase in uterine contraction forces, the controller causes an agent to be delivered from the agent source to the balloon body to expand the balloon body. In response to a detection of a decrease in uterine contraction forces, the controller causes agent to discharge from the balloon body to collapse the balloon body.
