Abstract

According to features of the present disclosure, a gastric space filler device and methods effective for reducing stomach volume are disclosed. A gastric space filler comprising at least one inflatable space filler and a sleeve to prevent leakage out of the gastric space filler device is disclosed. The gastric space filler device may be inflated with an insufflation fluid and with mineral oil, which further has the effect of reducing leakage. Delivery systems and methods for inserting a gastric space filler device into a patient are also disclosed. Sheaths and methods for covering a gastric space filler device during delivery into a patient are also disclosed.

Claims

1-20. -20. (canceled)

21. A method of delivering a gastric space filler device, the method comprising:

delivering a guidewire through an esophagus to a stomach;

guiding a gastric space filler device and a delivery system configured to be releasably attached to the gastric space filler device along a path defined by the guidewire to the stomach; and

inflating a space filler of the gastric space filler device with a fluid provided from the delivery system through an infusing lumen in an infusing member of the gastric space filler device.

22. The method of claim 21 wherein the delivery system is attached to the gastric space filler device before the gastric space filler device and the delivery system are guided along the path defined by the guidewire, and wherein the method further comprises detaching the delivery system from the gastric space filler device after at least partially inflating the space filler.

23. The method of claim 22, further comprising attaching the delivery system to the gastric space filler device by inserting a barb of the delivery system into a gate at a proximal end of the infusing member of the gastric space filler device.

24. The method of claim 23 wherein attaching the delivery system to the gastric space filler device comprises attaching the delivery system such that the barb provides fluid communication between a delivery lumen of the delivery system and the infusing lumen of the gastric space filler device when the barb is inserted into the gate.

25. The method of claim 23, further comprising detaching the delivery system from the gastric space filler device by removing the barb from the proximal end of the infusing member after at least partially inflating the space filler.

26. The method of claim 25 wherein removing the barb from the proximal end of the infusing member causes the gate to close.

27. The method of claim 21 wherein the infusing member of the gastric space filler device comprises a filler guide wire channel and the delivery system comprises a delivery guide wire channel, and wherein the method further comprises threading the guidewire through at least one of the filler guide wire channel and the delivery guide wire channel before guiding the gastric space filler device and the delivery system along the path defined by the guidewire.

28. The method of claim 27 wherein the filler guide wire channel extends from a proximal end of the infusing member to a distal end of the infusing member.

29. The method of claim 21, further comprising at least partially covering the gastric space filler device with a sheath before guiding the gastric space filler device along the guidewire.

30. A gastric space filler device, comprising:

a flexible, elongate infusing member having a proximal end, a distal end, and a guide wire channel extending completely through the infusing member from the proximal end to the distal end; and

a plurality of inflatable gastric space fillers secured to the infusing member.

31. The gastric space filler device of claim 30, further comprising a delivery system configured to be releasably attached to the gastric space filler device, wherein the delivery system comprises:

a proximal barb positioned to engage a proximal delivery lumen of the infusing member and provide fluid communication between the delivery system and a proximal inflatable space filler coupled to the infusing member; and

a distal barb positioned to engage a distal lumen of the infusing member and provide fluid communication between the delivery system and a distal inflatable space filler coupled to the infusing member.

32. The gastric space filler device of claim 31 wherein the delivery system is configured to be attached to the gastric space filler device with a barb of the delivery system inserted into a gate at the proximal end of the infusing lumen.

33. The gastric space filler device of claim 31 wherein the delivery system further comprises a delivery guide wire channel aligned with the filler guide wire channel when the delivery system is releasably attached to the gastric space filler device.

34. The gastric space filler device of claim 33, further comprising a guidewire threaded through the filler guide wire channel and the delivery guide wire channel.
