1. A gastric space filler device, comprising:
- a space filler including an opening;
a sleeve;
an infusing member coupled with the space filler and extending from outside the space filler to within an interior portion of the space filler,wherein the infusing member comprises an infusing lumen in fluid communication with the opening,wherein the opening is disposed on a portion of the infusing member that is within the interior portion of the space filler,wherein the opening provides fluid communication between the infusing lumen and the interior portion of the space filler, andwherein the sleeve covers the opening on a side thereof facing the interior portion of the space filler;
an inflation fluid within the interior portion of the space filler, wherein the inflation fluid is delivered from the infusing lumen through the opening; and
an oil delivered from the infusing lumen through the opening and received between the sleeve and the opening, wherein the oil is a material other than the inflation fluid, wherein the oil is configured to inhibit leakage of the inflation fluid out of the space filler.

Abstract
A gastric space filler device effective for reducing stomach volume comprises at least one inflatable space filler and a sleeve to prevent leakage out of the gastric space filler device. 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 are effective for inserting a gastric space filler device into a patient. The gastric space filler device may be provided with sheaths and methods for covering the gastric space filler device during delivery into a patient.

14. A method for treating obesity challenged patients the method comprising:
-
delivering a gastric space filler device to a stomach, wherein the gastric space filler device comprises a space filler including an opening, the opening being disposed on an infusing member extending from outside the space filler to within the space filler, and a sleeve covering the opening on a side thereof facing an interior portion of the space filler; inflating the interior portion of the space filler with an insufflation fluid from the infusing member through the opening; and providing mineral oil from the infusing member through the opening to between the sleeve and the opening of the infusing member, whereby the mineral oil displaces the insufflation fluid from between the sleeve and the opening of the infusing member to inhibit leakage of the insufflation fluid out of the space filler. - View Dependent Claims (15, 16, 17)

18. A method for emplacing a gastric space filler device in a patient, the method comprising:
-
delivering a gastric space filler device through an esophagus into a stomach of a patient, wherein the gastric space filler device comprises a proximal space filler and a distal space filler on an infusing member, a proximal sheath at least partially covering a proximal portion of the proximal space filler, and a central sheath at least partially covering a distal portion of the proximal space filler and a proximal portion of the distal space filler; inflating the proximal space filler, wherein inflating the proximal space filler causes the proximal sheath to be rolled onto itself toward a proximal end of the proximal space filler and the central sheath to be rolled onto itself toward a distal end of the proximal space filler; and inflating the distal space filler, wherein inflating the distal space filler causes the central sheath to be rolled onto itself toward a proximal end of the distal space filler. - View Dependent Claims (19, 20)
