An implantable restriction device is configured to provide a restriction in a patient as a function of the pressure of fluid. The implantable restriction device includes one or more pressure sensors configured to sense pressure of the fluid within the implantable restriction device. Pressure data obtained by the one or more pressure sensors may be communicated to a device located external to the patient, which may process the pressure data, and may further provide a display to a user including information relating to the processed pressure data. Where the implantable restriction device comprises an adjustable gastric band, the one or more pressure sensors may be located in any number of the following locations: an injection port, an interface between the injection port and a catheter, in a catheter, in-line with a catheter, adjacent to a catheter, in a gastric band, in a gastric band buckle, or elsewhere.

What is claimed is: 1. A restriction system for forming a restriction in a patient, the system comprising: (a) an implantable restriction device, wherein the implantable restriction device is operable to form a restriction in a patient; (b) an implantable port in fluid communication with the implantable restriction device, wherein the implantable port is configured to receive fluid from a fluid source external to the patient, wherein the implantable port comprises a needle penetrable septum and a housing, wherein the septum is configured to receive a needle for injection of fluid into the port or withdrawal of fluid from the port; (c) an implantable fluid conduit positioned between the implantable restriction device and the implantable port, wherein the implantable conduit is configured to permit communication of fluid from the implantable port toward the implantable restriction device, wherein the implantable conduit is further configured to permit communication of fluid from the implantable restriction device toward the implantable port; (d) a fluid, wherein the fluid is located within each of the implantable restriction device, the implantable port, and the implantable fluid conduit; (e) a first implantable pressure sensor, wherein the first implantable pressure sensor is in fluid communication with the fluid and positioned within the implantable port, wherein the first implantable pressure sensor is operable to sense the pressure of the fluid within the implantable port, wherein the first implantable pressure sensor is further operable to communicate pressure data to an external monitor; and (f) a second implantable pressure sensor, wherein the second implantable pressure sensor is located in one of the implantable fluid conduit or the implantable restriction device. 2. The restriction system of claim 1, wherein the implantable restriction device comprises an adjustable gastric band. 3. The restriction system of claim 1, wherein the restriction has a variable size, wherein the size is a function of pressure of the fluid. 4. The restriction system of claim 1, wherein the first implantable pressure sensor comprises a mechanically deformable surface in communication with the fluid, wherein the mechanically deformable surface is configured to deform in proportion to the pressure of the fluid. 5. The restriction system of claim 1, wherein the implantable fluid conduit comprises a “T”-shaped portion, wherein the second implantable pressure sensor is located in the “T”-shaped portion of the implantable fluid conduit. 6. The restriction system of claim 1, wherein the second implantable pressure sensor is located in-line with the implantable fluid conduit. 7. The restriction system of claim 1, wherein the implantable fluid conduit comprises a first catheter and a second catheter, wherein the second implantable pressure sensor is located between the first catheter and the second catheter. 8. The restriction system of claim 7, wherein the second implantable pressure sensor is located within a housing, wherein the housing is fixedly secured to the first catheter and the second catheter, such that the housing forms part of the implantable fluid conduit. 9. The restriction system of claim 7, wherein the second implantable pressure sensor is located within a housing, wherein the housing is removably secured to the first catheter and the second catheter, such that the housing forms part of the implantable fluid conduit. 10. The restriction system of claim 9, wherein the housing comprises barbed connectors configured to engage the first catheter and the second catheter. 11. The restriction system of claim 1, wherein the implantable restriction device comprises a buckle, wherein the second implantable pressure sensor is located within the buckle. 12. An implantable restriction system, the system comprising: (a) a means for forming a restriction within a patient; (b) a means for adjusting the restriction within the patient, wherein the means for adjusting the restriction comprises a fluid in communication with the means for forming a restriction within the patient; (c) an injection port in fluid communication with the means for forming a restriction within the patient, wherein the injection port comprises a needle penetrable septum and a housing, wherein the septum is configured to receive a needle for injection of fluid into the port or withdrawal of fluid from the port; (d) a fluid conduit coupling the injection port with the means for forming a restriction within a patient; (e) a first means for sensing pressure of the fluid, wherein the first means for sensing pressure of the fluid is in fluid communication with the fluid, wherein the first means for sensing pressure of the fluid is positioned within the means for forming a restriction within the patient; (f) a second means for sensing pressure of the fluid, wherein the second means for sensing pressure of the fluid is in fluid communication with the fluid, wherein the second means for sensing pressure of the fluid is positioned within one of the injection port or the fluid conduit; (g) a means for processing fluid pressure data, wherein the means for processing fluid pressure data is located external to a patient; and (h) a means for communicating pressure data obtained with the first and second means for sensing pressure to the means for processing fluid pressure data. 13.
