Claims29
A system for controlled drug delivery on-demand to a gastrointestinal system of a patient, the system comprising:
- a gastric space filler;
- a drug reservoir in the gastric space filler;
- a pump secured to the reservoir and configured to dispense a drug from the drug reservoir;
- and
- a sensor configured to receive at least one signalling parameter from an interior of a stomach of the patient, the sensor being functionally connected to the pump and configured to trigger delivery of the drug when the at least one parameter reaches a threshold of a preset value.
A system for sustained drug delivery to a gastrointestinal system of a human patient, the system comprising:
- a gastric space filler comprising a wall having an exterior surface, wherein the gastric space filler comprises at least two balloons connected by a conduit, and wherein the gastric space filler is configured to occupy a substantial volume of a gastric cavity in the human patient in an inflated state;
- and
- a drug coated onto at least a portion of the exterior surface of the wall and impregnated in at least a portion of the wall, wherein the drug coating comprises a drug carrier loaded with a drug.
