1. A medical system, comprising: a medical device configured to be implanted within a patient, the medical device including capsule having an exterior surface and electronic componentry sealed within the capsule; andan engagement tool configured to couple to the medical device post implantation, such that the engagement tool can be used to adjust the position of the medical device when coupled to the medical device and wherein the electronic componentry includes electrical circuitry configured to generate stimulation pulses or drug delivery doses in accordance with a plurality of stimulation parameters. 2. The medical system of claim 1, further comprising a cannula configured to be inserted into the patient adjacent the implanted medical device, the cannula having a lumen through which the engagement tool is configured to be inserted. 3. The medical system of claim 1, further comprising a cannula configured to be inserted into the patient adjacent the implanted medical device, the cannula having a cutting edge configured for cutting away tissue surrounding the implanted medical device to release the medical device from the tissue, the cannula further having a lumen configured for receiving the released medical device. 4. The medical system of claim 3, wherein the engagement tool includes the cannula. 5. The medical system of claim 3, wherein the engagement tool is configured to be inserted into the lumen of the cannula. 6. The medical system of claim 1, wherein a rotation of the engagement tool is configured to release the medical device from surrounding tissue. 7. The medical system of claim 1, wherein the medical device includes an engagement component affixed to the exterior surface of the medical device capsule, and wherein the engagement tool is configured to couple to the engagement component, such that the engagement tool can be used to adjust the position of the medical device when coupled to the engagement component. 8. The medical system of claim 7, wherein the engagement component includes a plurality of crenulations located about the perimeter of the engagement component, and wherein the engagement tool includes a number of teeth configured to engage the crenulations. 9. The medical system of claim 8, wherein the engagement component includes a tapered edge configured to deflect the teeth outward as the engagement tool begins to engage the engagement component, such that the teeth lock into the respective crenulations as the teeth are slid over the crenulations. 10. The medical system of claim 9, wherein each of the teeth includes a tapered edge configured to slide against the tapered edge of the engagement component as the engagement tool begins to engage the engagement component. 11. The medical system of claim 1, wherein the engagement tool includes a net configured to be tightened around the implanted medical device. 12. The medical system of claim 11, wherein the engagement tool further includes one or more wires coupled to the net for adjusting a position of the net. 13. The medical system of claim 11, wherein the engagement tool further includes a needle for guiding the net to the implanted medical device. 14. The medical system of claim 1, wherein the engagement tool includes a syringe device configured to applying a vacuum pressure to the medical device to adjust the position of the medical device. 15. The medical system of claim 14, wherein the electronic componentry includes one or more processors. 16. The medical system of claim 1, wherein the engagement tool includes a cannula configured to be inserted into the patient adjacent the implanted medical device, the cannula having a lumen configured for receiving the medical device and one or more members inwardly extending within the lumen to prevent the medical device from advancing beyond a predetermined point within the lumen. 17. The medical system of claim 1, wherein the medical device includes one or more concave notches formed in the housing of the medical device, and wherein the engagement tool includes a cannula configured to be inserted into the patient adjacent the implanted medical device, the cannula having a lumen configured for receiving the medical device and one or more corresponding convex members configured to engage with the one or more corresponding concave notches of the medical device when the medical device is received within the lumen of the cannula. 18. The medical system of claim 1, wherein the engagement tool includes a cannula configured to be inserted into the patient adjacent the implanted medical device, the cannula having a lumen configured for receiving the medical device, wherein the lumen is at least partially filled with a fluid through which energy can be transmitted to the implanted medical device to loosen the medical device from surrounding tissue. 19. The medical system of claim 1, wherein the engagement tool includes a plurality of gripping arms configured to engage the medical device. 20. The medical system of claim 19, further comprising a cannula configured to be inserted into the patient adjacent the implanted medical device, the cannula having a lumen configured for receiving the medical device and through which the engagement tool is configured to be inserted, wherein the gripping arms are configured to be placed into an open position as they extend from the lumen of the cannula, such that the open gripping arms can be disposed around the medical device, and wherein the gripping arms are configured to be placed into a closed position as they are retracted within the lumen of the cannula, such that the closed gripping arms engage the medical device. 21. The medical system of claim 1, wherein the engagement tool includes a clamping member configured to clamp onto the medical device. 22. The medical system of claim 1, wherein the engagement tool includes an adjustable loop structure configured to couple to the medical device. 23. The medical system of claim 1, wherein the engagement tool comprises a magnet configured to magnetically couple to the medical device. 24. The medical system of claim 23, wherein the electronic componentry includes one or more processors. 25. The medical system of claim 1, wherein the electronic componentry further includes memory configured for storing the plurality of stimulation parameters. 26. The medical system of claim 1, wherein the electronic componentry further includes a power source configured for supplying the electrical circuitry with power. 27. The medical system of claim 1, wherein the electronic componentry includes one or more processors.
