  • Publication number: 20240099601
    Abstract: A manometry system includes a manometric catheter configured to sense pressure within a gastrointestinal tract, a wireless assembly configured for transmitting/receiving signals to/from the catheter, and a base unit configured to calibrate the catheter prior to usage thereof and to store and charge a wireless electronics module of the wireless assembly.

  • Publication number: 20230363660
    Abstract: A manometric catheter probe includes a flexible printed circuit, one or more pressure sensor assemblies coupled to the flexible printed circuit along a length of the flexible printed circuit, and a first flexible sleeve. Each pressure sensor assembly includes a body. The body includes a central cavity configured to receive the flexible printed circuit and an annular recess of the body. Each pressure sensor assembly further includes a microelectromechanical systems (MEMS) sensor disposed in the annular recess, an electrical connector configured to electrically couple the MEMS sensor and the flexible printed circuit, and a first flexible sleeve disposed over the annular recess of the body. The first flexible sleeve includes a fluid configured to communicate pressure to the MEMS sensor, and a second sleeve is disposed over the pressure sensor assembly.

  • Patent number: 6269813
    Abstract: Tracheal gas insufflation (TGI) therapy is performed by a bypass valve and a controller which control a flow of TGI gas to a TGI catheter inserted into an endotracheal tube in the tracheal of a patient. The bypass valve is activated into a pass-through state to admit the TGI gas into the catheter and into a bypass state to divert the TGI gas from the TGI catheter. Potentially dangerous over-pressure may be sensed and the TGI gas flow terminated, but then quickly resumed after the over-pressure condition passes. Selectively applying and diverting the TGI gas allows phasic TGI therapy to be performed using heated and humidified gas and also allows the heat and humidity levels of the TGI gas to be maintained during continuous TGI therapy.
