Prepackaged collections of the devices and supplies (either custom or standard) needed for injection of a liquid agent into specific gastrointestinal tissue (e.g., the region of the lower esophageal sphincter) and allowed to precipitate as a solid permanent implant increasing tissue bulk. Items in these kits usually include two containers with the implantable solution (e.g., a biocompatible copolymer and a radio opaque marker) and a liquid solvent respectively, a catheter with an injection needle, a syringe, and a hypodermic needle. These kits may be supplied in supporting trays (i.e., procedure trays) consisting of a flat-bottomed receptacle with a border around the periphery supporting all the instruments and supplies needed for the procedure; the trays are usually covered or wrapped. Gastrointestinal bulking agent injection procedure kits and trays are intended for the treatment of specific disorders (e.g., esophageal sphincter reflux).
