  • Patent number: 11571555
    Abstract: An automatic pump-based fluid management system, as described herein, comprises an intercostal pump that is, generally, a resiliently flexible bulb having an inlet and an outlet. The inlet is attached to a first tube that extends from the intercostal pump to a first area of a patient's body, for example, the patient's pleural cavity. The outlet is connected to a second tube that extends from the intercostal pump to a second area of a patient's body, for example, the patient's peritoneal cavity. In use, the intercostal pump is placed between a first rib and a second rib in a patient. The intercostal pump operates by being successively compressed and decompressed between the first and second ribs as the patient breaths.

  • Patent number: 11565095
    Abstract: Embodiments of the invention provide swallowable devices, preparations and methods for delivering drugs and other therapeutic agents (TA) within the GI tract and in particular to an antrum wall (AW). Particular embodiments provide a swallowable device (SD) such as a capsule for delivering drugs or other TA into the AW. The SD may contain a pressure sensitive component or assembly which triggers release and insertion of a therapeutic agent preparation (TAP) comprising at least one TA into the AW in response to external pressure, such as pressure applied to the swallowable capsule or other SD by antrum contractions. Particular embodiments of the SD may be shaped so that they self-align within an antrum to properly orient before injection of the TAP into the AW. Embodiments of the invention are particularly useful for orally delivering drugs or other TAs which are degraded within the GI tract and require parenteral injection.

  • Patent number: 11554214
    Abstract: A surgical fluid management system includes a console and a cassette for delivering fluids to a surgical site. The console has a pump rotor and a pressure-sensing membrane. The cassette has a cassette housing, a flexible fluid delivery tube in the housing. The flexible fluid delivery tube has a lumen configured to interface with the pump rotor and to deliver a flow of fluid from a fluid source as the rotor is rotated. A pressure-transmitting membrane is located in a wall of the cassette housing and in fluid communication with said fluid delivery lumen. The pressure-transmitting membrane flexes outwardly in response to a positive pressure in the lumen and flexes inwardly in response to a negative pressure in the lumen. The pressure-transmitting membrane detachably adheres to or presses against the pressure-sensing membrane to cause the pressure-sensing membrane to move in response to pressure changes in the flexible fluid delivery tube.
