Abstract: An intrauterine balloon apparatus to augment uterine birthing forces and assist fetal descent during parturition is provided. The body of the balloon apparatus begins packaged in a compressed state minimizing volume, enabling delivery through the birth canal. The apparatus is advanced to a proximal uterine location and deployed for operation by introducing a pressurized agent through its conduit, causing the body to expand and apply directional forces towards the infant and birth canal. The balloon body is shaped to apply pressures dispersed towards the infant and the bidirectional conduit enables fluid conduction as the infant descends. After the infant has successfully descended and been delivered through the birth canal, pressure within the balloon body is relieved through the conduit thereby collapsing the volume of the balloon body and enabling refraction through the birth canal.

Abstract: A handheld device measures all vital signs and some hemodynamic parameters from the human body and transmits measured information wirelessly to a web-based system, where the information can be analyzed by a clinician to help diagnose a patient. The system utilizes our discovery that bio-impedance signals used to determine vital signs and hemodynamic parameters can be measured over a conduction pathway extending from the patient's wrist to a location on their thoracic cavity, e.g. their chest or navel. The device's form factor can include re-usable electrode materials to reduce costs. Measurements made by the handheld device, which use the belly button as a ‘fiducial’ marker, facilitate consistent, daily measurements, thereby reducing positioning errors that reduce accuracy of standard impedance measurements. In this and other ways, the handheld device provides an effective tool for characterizing patients with chronic diseases, such as heart failure, renal disease, and hypertension.
