1. A cardiac care, medical system comprising: an implantable, medical device housing comprising a header, wherein the header includes a port comprising a probe receptacle and a membrane assembly positioned at an entrance to the probe receptacle, wherein the probe receptacle is configured to receive a probe from outside a body of a patient through the membrane assembly after the housing has been implanted inside the body of the patient, and wherein the probe receptacle comprises multiple, separate conductive segments arranged serially along a longitudinal axis of the probe receptacle and configured to align with corresponding multiple, separate conductive segments arranged serially along a longitudinal axis of the probe when the probe is inserted through the patient's skin and into the probe receptacle; andwherein the port is viewable with medical imaging while inside the body of the patient to facilitate guidance and mating of the probe to the port. 2. The medical system of claim 1, wherein the port includes an opaque material that makes it viewable with the medical imaging. 3. The medical system of claim 2, wherein the medical imaging includes X-ray imaging. 4. The medical system of claim 1, wherein the separate conductive segments arranged serially along the longitudinal axis of the probe receptacle comprise one or more contacts configured to provide one or more connections for transmitting communication signals to and/or from the medical system via the corresponding separate conductive segments of the probe when the probe is inserted into the probe receptacle. 5. The medical system of claim 1, wherein the port is configured to receive the probe in electrical isolation from the body of the patient. 6. The medical system of claim 1, wherein the probe receptacle includes one or more seals arranged serially along the longitudinal axis of the probe receptacle and configured to electrically isolate the individual conductive segments of the probe receptacle from each other. 7. The medical system of claim 6, wherein the membrane assembly includes a bodily fluid seal configured to seal the probe receptacle segments from bodily fluid when the probe enters the probe receptacle through the port after piercing the patient's skin. 8. The medical system of claim 7, wherein the bodily fluid seal is adjacent to the entrance to the probe receptacle. 9. The medical system of claim 1, wherein the housing includes a body orientation sensing unit configured to determine a physical orientation of at least a portion of the patient's body and to output orientation data corresponding to the physical orientation of the at least a portion of the patient's body. 10. A medical system comprising: an implantable medical device comprising a header, wherein the header includes a port comprising a probe receptacle and a membrane assembly positioned at an entrance to the probe receptacle, wherein the probe receptacle is configured to receive a probe from outside a patient's body through the membrane assembly after the medical device has been implanted inside the body of the patient, and wherein the probe receptacle includes multiple electrically-conductive segments arranged serially along a longitudinal axis of the probe receptacle;a probe comprising one or more electrically-conductive segments arranged serially along a longitudinal axis of the probe, and wherein the probe is configured to deliver at least one of energy and data to the medical device from outside of the patient's body after the probe has been inserted into the probe receptacle of the medical device through the port, thereby causing individual electrically-conductive segments of the probe to contact corresponding individual electrically-conductive segments of the probe receptacle; andwherein the port is viewable with medical imaging while inside the patient's body to facilitate guidance and mating of the probe to the port. 11. The medical system of claim 10, wherein the probe is configured to mate with the implantable medical device via the port by inserting the probe through the patient's skin and into the probe receptacle after the medical device has been implanted inside the body of the patient. 12. The medical system of claim 11, wherein the multiple electrically-conductive segments of the probe are configured to act as one or more cathode connections and one or more anode connections for energy delivery to the implantable medical device from a power source located outside of the patient's body. 13. The medical system of claim 11, wherein the multiple electrically-conductive segments of the probe are configured to provide one or more connections for transferring communication signals to and/or from the implantable medical device to/from a communications device located outside of the patient's body. 14. The medical system of claim 10, wherein the multiple electrically-conductive segments of the probe are electrically isolated from each other, and wherein the multiple electrically-conductive segments of the probe receptacle are electrically isolated from each other. 15. The medical system of claim 14, wherein the probe has a needle-shape, is smooth along its outer surface, and has a tip to ease penetration of the skin. 16. The medical system of claim 15, wherein the probe includes a smooth outer surface to at least a depth required to penetrate the patient's body to reach and engage a distal end of the probe receptacle. 17. The medical system of claim 14, wherein the probe is tapered from a tip to ease penetration into the patient's body. 18. The medical system of claim 14, wherein the probe includes one or more sets of cathode and anode segments configured to transfer electrical energy into the implantable medical device from a power source located outside of the patient's body, and one or more sets of communications interfaces configured to transmit data to/from the implantable medical device to/from a communications systems located outside of the patient's body. 19. The medical system of claim 18, wherein the membrane assembly positioned at the entrance to the probe receptacle is configured to prevent moisture from leaking into the probe receptacle. 20. The medical system of claim 19, wherein the probe receptacle is generally cylindrical. 21.
