Inflation devices for intragastric devices with improved attachment and detachment and associated systems and methods
First Claim
1. A system, comprising:
- an intragastric device including an inflatable balloon, a proximal cap having a flanged section, and an inflation port at a proximal portion of the intragastric device; and
an inflation device comprising—
an outer detent at a distal portion of the inflation device configured to connect over the proximal cap of the intragastric device;
an inner detent having a mating interface; and
at least one tube fluidly connecting a handle at a proximal portion of the inflation device to a barb at the distal portion of the inflation device, the barb having a cross-sectional dimension greater than a cross-sectional dimension of the inflation port of the intragastric device when the inflation port is unengaged from the barb, wherein the barb is configured to expand the proximal cap when the barb is inserted into the inflation port such that the flanged section of the proximal cap expands into the outer detent.

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.
