An implant unit is implanted in an area of a body and a foreign body capsule is allowed to form around the area of the implant unit. The sensor may be directed into a body cavity such as, for example, the peritoneal space, subcutaneous tissues, the foreign body capsule, or other area of the body. A subcutaneous area of the body may be tunneled to place the sensor. The system may include an implant unit such as, for example, for delivering drug to a human body and a sensor for detecting a physiological parameter. The sensor may be separate from and connectable to the implant unit and may be placed in a non-vascular area of the human body. ## Claims ### Claim 1 A method for non-vascular implant of a sensor comprising: implanting an implant unit in an area of a body capable of forming a foreign body capsule without passing the implant unit through a vascular system; allowing a foreign body capsule to form around the area of the implant unit; directing a sensor into the foreign body capsule; and connecting the sensor to the implant unit subsequent to formation of the foreign body capsule. ### Claim 2 (depends on 1) The method of claim 1, wherein implanting an implant unit comprises incising an area of the body large enough for the implant unit. ### Claim 3 (depends on 1) The method of claim 1, further comprising placing a material around the implant unit for promoting growth characteristics. ### Claim 4 (depends on 1) The method of claim 1, wherein the implant unit comprises electronics. ### Claim 5 (depends on 1) The method of claim 1, wherein the implant unit comprises a pump. ### Claim 6 (depends on 1) The method of claim 1, wherein allowing a foreign body capsule to form comprises inserting materials around the implant unit to promote growth characteristics. ### Claim 7 (depends on 1) The method of claim 1, further comprising attaching the sensor to the implant unit. ### Claim 8 (depends on 7) The method of claim 7, wherein the sensor is attached to the implant unit prior to formation of the foreign body capsule. ### Claim 9 (depends on 7) The method of claim 7, wherein the sensor is attached to the implant unit subsequent to formation of the foreign body capsule. ### Claim 10 (depends on 1) The method of claim 1, further comprising incising an area of the body large enough for the sensor. ### Claim 11 (depends on 10) The method of claim 10, wherein the incised area of the body large enough for the sensor is smaller than an incised area of the body large enough for the implant unit. ### Claim 12 (depends on 1) The method of claim 1, wherein implanting the implant unit includes inserting the implanting unit into an incision and closing the incision. ### Claim 13 (depends on 1) The method of claim 1, wherein the sensor is located away from the location of the implant unit area. ### Claim 14 (depends on 1) The method of claim 1, wherein the area of the body capable of forming a foreign body capsule includes abdominal, spinal or chest cavities. ### Claim 15 (depends on 1) The method of claim 1, wherein directing the sensor into the foreign body capsule is performed after the formation of the foreign body capsule. ### Claim 16 (depends on 1) The method of claim 1, wherein directing the sensor into the foreign body capsule comprises making a small incision in the foreign body capsule to allow access to the implant unit. ### Claim 17 (depends on 1) The method of claim 1, wherein allowing a foreign body capsule to form includes waiting a sufficient time after implanting the implant unit for the formation of the foreign body capsule. ### Claim 18 A method for non-vascular implant of a sensor comprising: implanting an implant unit in a body cavity capable of forming a foreign body capsule; allowing a foreign body capsule to form around the implant unit; directing a sensor into the foreign body capsule; and connecting the sensor to the implant unit subsequent to formation of the foreign body capsule. ### Claim 19 (depends on 18) The method of claim 18, wherein implanting the implant unit includes, inserting the implanting unit into an incision and closing the incision. ### Claim 20 (depends on 18) The method of claim 18, wherein the body cavity capable of forming a foreign body capsule includes abdominal cavity, spinal cavity or chest cavity.
