6. The apparatus of claim 5 wherein the control processor analyzes transitions from video signal for plural laser scan lines to determine if a barcode like object is located in an active image field for the imaging scanner.
7. The apparatus of claim 6 wherein the control processor automatically drives the lighting arrangement and triggers the imaging scanner to attempt to read the barcode like object located in the active image field.
8. The apparatus of claim 1 wherein the imaging scanner further comprises a manual trigger which is active when the imaging scanner is not in the docked position.
9. The apparatus of claim 1 wherein the control processor is in the dual aperture scanner and drives a wireless transmitter to transmit control signals to the imaging scanner to control the lighting arrangement.

11. The apparatus of claim 1 wherein the imaging scanner and the dual aperture scanner share the control processor.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A method, comprising the steps of:
inducing a pressure difference across the peritoneum of a patient to increase a total volume of peritoneal fluid in an implanted medical device,
performing one or more steps selected from the group consisting of:
1) dialyzing the blood across the peritoneal membrane, wherein peritoneal fluid is conveyed to a space inside of the implanted medical device and then conveyed to a dialysis chamber having a dialysate to reduce the concentration of waste components in the peritoneal fluid conveyed to the implanted medical device;
2) dialyzing the blood across the peritoneal membrane, wherein peritoneal fluid is conveyed to an inside of the implanted medical device and then contacted with a dialysis chamber having dialysate to reduce the concentration of waste components in the peritoneal fluid conveyed to the implanted medical device and using an electrical potential to regenerate the dialysate; and
3) removing excess fluid from the patient by removing at least part of the fluid from the implanted medical device from the patient, and
inducing a pressure difference across the peritoneum to decrease the total volume of fluid in the implanted medical device and return fluid from inside the medical device to the patient.
2. The method of claim 1, further comprising the step of cleansing the dialysate in a closed loop.
3. The method of claim 1, further comprising the step of directing at least part of the peritoneal fluid to the patient’s urinary bladder.
4. The method of claim 1, wherein the dialysis chamber or an electrodialyzer for using an electrical potential to regenerate the dialysate is located extracorporeally.
5. The method of claim 4, wherein the electrodialyzer further comprises an adjustable voltage generator to generate electrical fields of varying magnitudes for selective removal of waste components.
6. The method of claim 3, further comprising a pump to assist andor control flow of the peritoneal fluid through a catheter to the patient’s urinary bladder.
7. The method of claim 6, further comprising piezoelectric vibrators placed adjacent to the catheter to reduce calcification of the catheter.
8. The method of claim 1, further comprising regenerating the dialysate from the dialysis chamber using a dialysate cleansing unit.
9. The method of claim 8, wherein the dialysate cleansing unit comprises sorbent packages.
10. The method of claim 9, wherein the sorbent packages are replaceable.
11. The method of claim 1, further comprising supplying a fresh supply of dialysate to the dialysate chamber.
12. The method of claim 1, wherein the implanted medical device comprises a partially porous mesh that forms a fibrosis cage upon implantation into a patient, the fibrosis cage defining a space for accessing fluid from the patient.
13. The method of claim 12, wherein the mesh is treated with at least one of a surface coating of fibrosis-inducing agents, and extracellular matrix components to promote growth of fibrous tissue.
14. The method of claim 12, wherein the implanted medical device further comprises a pumping means for pumping fluid into and out of the fibrosis cage.
15. The method of claim 12, wherein the fibrosis cage further comprises a material impermeable to cells surrounding the partially porous mesh.
16. The method of claim 14, wherein the pumping means is one selected from the group consisting of a bellows pump, a peristaltic pump, a pulsatile pump, an impeller pump, and a syringe pump, said pump means positioned inside the partially porous mesh, outside the partially porous mesh or adjacent to the partially porous mesh.
