Gastric space filler device, delivery system, and related methods
First Claim
1. A method of delivering a gastric space filler device, the method comprising:
- attaching a delivery system to a gastric space filler device by releasably coupling a docking clip of the delivery system to a docking notch at a proximal end of an infusing member of the gastric space filler device;
delivering a guidewire through an esophagus to a stomach;
after the delivery system is attached to the gastric space filler, guiding the gastric space filler device and the delivery system together over the guidewire to the stomach;
inflating a space filler of the gastric space filler device with a fluid provided from the delivery system through an infusing lumen in the infusing member of the gastric space filler device;
detaching the delivery system from the gastric space filler device by removing the docking clip from the docking notch; and
removing the delivery system from the stomach without removing the gastric space filler device from the stomach.
