A first gear is coupled to the base, and a first anchor is coupled to the first gear. A second gear is coupled to the base, and a second anchor is coupled to the second gear. A top portion of the injection port is spaced apart from the base of the port and has a first plurality of top teeth that engage with a first plurality of gear teeth on the first gear. This engagement occurs prior to rotation of the second gear. The top portion rotates, which causes rotation of the first gear, which in turn causes movement of the first anchor through the anchor opening of the base and into the tissue of the patient. The first gear and the second gear rotate non-simultaneously. ## Claims ### Claim 1 An implantable injection port for use with a gastric band for treating obesity and for attaching to a tissue of a patient, the implantable injection port comprising: a base having a first anchor opening;

a first drive band coupled to a trigger of the actuation device; a second drive band coupled to the first drive band for translating motion from the trigger of the actuation device to the second drive band, wherein the second drive band is configured to interface with a top portion of the implantable injection port to facilitate deploying an anchor of the implantable injection port into the tissue of the patient; and a switch operable to direct the second drive band to rotate the top portion of the implantable injection port in an implanting direction or a retracting direction. ### Claim 17 (depends on 16) The actuation device of claim 16, wherein a face of the first drive band is substantially perpendicular to a face of the second drive band, and wherein the first drive band is a horizontal drive band and the second drive band is a vertical drive band. ### Claim 18 (depends on 16) The actuation device of claim 16, wherein the head is a gripping portion configured to be coupled to the implantable injection port via a snap feature. ### Claim 19 (depends on 16) The actuation device of claim 16, wherein the implanting direction of the top portion facilitates implanting the anchor in the tissue of the patient, and wherein the retracting direction of the top portion facilitates retracting the anchor from the tissue of the patient. ### Claim 20 (depends on 16) The actuation device of claim 16, wherein the implanting direction is clockwise and the retracting direction is counter clockwise. ### Claim 21 (depends on 16) The actuation device of claim 16, wherein the switch is manually or automatically toggled to a retracting mode after the trigger is depressed and released to implant the anchor in the tissue of the patient. ### Claim 22 (depends on 21) The actuation device of claim 21, wherein the switch is toggled by rotating from a first position to a second position, wherein the first position guides the second drive band to rotate the top portion of the implantable injection port in the implanting direction, and wherein the second position guides the second drive band to rotate the top portion of the implantable injection port in the retracting direction. ### Claim 23 A method for implanting an implantable injection port in a tissue of a patient, the method comprising: coupling a gripping portion of an actuation device to a top portion of the implantable injection port; depressing a trigger of the actuation device when a switch in the actuation device is located in an implanting orientation; directing a vertical drive band through the switch to contact the top portion of the implantable injection port and rotate the top portion in an implanting direction; implanting, at a first time, a first anchor into the tissue of the patient in response to a first set of top teeth causing a first gear to rotate, wherein the first anchor is coupled to the first gear; implanting, at a second time, a second anchor into the tissue of the patient in response to the first set of top teeth causing a second gear to rotate, wherein the second anchor is coupled to the second gear; and toggling the switch to an extracting orientation in response to the trigger being released. ### Claim 24 A system for implanting an implantable injection port in a tissue of a patient, the system comprising: an actuation device for attaching the implantable injection port to the tissue of the patient, the actuation device comprising: a head configured to be coupled to the implantable injection port; a first drive band coupled to a trigger of the actuation device; a second drive band coupled to the first drive band for translating motion from the trigger of the actuation device to the second drive band, wherein the second drive band is configured to interface with a top portion of the implantable injection port to facilitate deploying an anchor of the implantable injection port into the tissue of the patient;
