Implantable access port device and attachment system

A method for attaching an access port assembly for use in conjunction with an inflatable gastric band for the treatment of obesity, the access port assembly being for implantation in a patient by attachment to a tissue location of the patient with a delivery tool, the access port assembly having a tissue attachment mechanism, the delivery tool having a delivery head and an activation mechanism for deploying the tissue attachment mechanism, the method comprising:

• creating an incision in the patient, the incision offset from the tissue location;
• engaging the access port assembly with the delivery head of the delivery tool;
• inserting the delivery head of the delivery tool and the access port assembly into the incision in the patient;
• positioning the access port assembly substantially flat against the tissue location;
• activating the activation mechanism of the delivery tool;
• disengaging the delivery head of the delivery tool from the access port assembly;
• and
• removing the delivery head of the delivery tool from the incision in the patient.

A system for attaching to a tissue of a patient, an implantable access port for use in conjunction with an inflatable gastric band for the treatment of obesity, the system comprising:

• an access port assembly having
• an access port containing a fluid reservoir therein and having a needle penetrable septum, and
• a tissue attachment mechanism configured to attach the access port to the tissue of the patient;
• and
• a delivery tool having
• a delivery head configured to couple with the access port assembly,
• a handle coupled with the delivery head in an offset configuration wherein the delivery head extends away from the handle, and
• an activation mechanism configured to engage the tissue attachment mechanism when the delivery head is coupled with the access port assembly.
