Delivery system for inflatable implant

Abstract

An implant delivery system can be used to deliver an implant into a body. The implant delivery system can include an inflation tube and a tubular member surrounding the inflation tube. The inflation tube can be used to provide an inflation medium to the implant. The tubular member can have a distal tip and an opening spaced from the tip to allow the implant to be released through the opening into an anatomical structure within the body.
