A gastric band for placement around the stomach is described which is useful for the treatment and control of morbid obesity. The gastric band has an inner surface and an outer surface. The inner surface has an inflatable member disposed thereon which substantially completely covers the inner surface of the band. A remote fill port is in fluid communication with the interior of the inflatable member. The gastric band is invasively placed in an encircling position around the stomach by the facile closure of a single fastening means. After the band is fastened around the stomach, a fluid is injected into the inflatable member thereby constricting the stoma of the stomach. Preferably, measuring means situated within the stomach provides a measure of the stoma opening. The inflatable member is adjusted so that the stoma opening is at the desired diameter. The advantage of the present gastric band over prior art bands is that adjustment of the tensioning the band prior to inflation is not required inasmuch as the latitude for inflation provided by the enlarged inflatable member enables a versatile range of adjustment.
