Inflation devices for intragastric devices with improved attachment and detachment and associated systems and methods
First Claim
1. A method of inflating an intragastric device, the method comprising:
- connecting an inflation device with a proximal cap of an intragastric device, wherein an outer detent of the inflation device is mated around the proximal cap, and wherein an inner detent of the inflation device is mated against a portion of the proximal cap, and wherein the proximal cap has a flanged section;
inserting a barb of the inflation device into an inflation port of the intragastric device such that the flanged section of the proximal cap expands into the outer detent;
delivering the intragastric device to a gastric cavity;
flowing a fluid into the intragastric device via the barb and the inflation port, wherein a balloon of the intragastric device is inflated with the fluid;
retracting the barb from the inflation port; and
removing the outer detent from around the proximal cap and the inner detent from against the proximal cap to disconnect the inflation device from the proximal cap.

Abstract
Inflation devices for inflating intragastric devices and associated systems and methods are disclosed herein. In several embodiments, an inflation device can include a tube, an inner detent, and an outer detent. The tube can extend from a proximal portion of the inflation device to a distal portion of the inflation device, and can include a handle at the proximal portion and a barb at the distal portion. The barb can have a cross-sectional dimension greater than a cross-sectional dimension of a corresponding inflation port of an intragastric device. The inner detent can be positioned over the barb and can include a mating interface. The outer detent can be positioned over the inner detent, and can be configured to attach over a proximal cap of the intragastric device. The tube can be longitudinally advanceable relative to at least one of the inner and outer detents.
