Low profile combination device for gastrostomy or jejunostomy applications having anti-granuloma formation characteristics
First Claim
1. A combination device for gastrostomy or jejunostomy usage, said device comprising a retaining member, an elongated member and an activatable sealing member, said elongated member having a proximal portion connected to said retaining member and having a longitudinal axis, said elongated member comprising a first lumen and a second lumen, said sealing member being mounted on said elongated member, said retaining member being arranged to be located on skin of a being adjacent a stoma in an abdominal wall of the being and having a low profile with respect to the being'"'"'s skin, said retaining member including a first access port and a second access port, each of said access ports extending generally parallel to said longitudinal axis and being arranged to have a respective tube coupled thereto, said elongated member being arranged to pass through the stoma so that said first lumen can serve as a gastrostomy tube and said second lumen can serve as a jejunostomy tube, said sealing member being located on said proximal portion of said elongated member and being arranged to seal an interface between the stoma and said proximal portion of said elongated member, said first lumen having a distal end and at least one first access port adjacent said distal end of said first lumen, said second lumen having a distal end and at least one second access port adjacent said distal end of said second lumen, each of said first and second access ports being arranged to provide communication to respective ones of said first and second lumens.

Abstract
A combination device for gastrostomy or jejunostomy usage having a retaining member, an elongated member having a gastrostomy lumen and a jejustomy lumen, and an inflatable balloon mounted on the elongated member. The retaining member is of a low profile and is arranged to be located on the skin adjacent a stoma in the abdominal wall through which the elongated member extends. The balloon seals the stoma about the elongated member. The retaining member includes at least one access port to communicate with respective ones of the lumens. The device, related compositions, and processes can prevent and/or treat granulomas.
