Esteem isn't for deaf people. It is only for hard of hearing people .You need to have good speech scores to get these.
You are correct that the FDA recommends the Esteem for those with moderate to severe hearing loss and (hearing-aided) word recognition scores at no less than 40%. However, there is mounting evidence that Middle-Ear-Implants such as the Esteem can treat severe-to-profound hearing loss in the upper pitches better than hearing aids. And considering that you would be the one to pay for these (not covered by any insurance), the FDA guidelines are only that: guidelines. Not rules. It's up to you and the doctor.
I didn't say that the Esteem was for deaf people. I said that it has shown particular promise for people like you and I who have usable hearing in the lower pitches but profound hearing loss in the upper pitches, who find little benefit from traditional hearing aids. (Pardon me if I am being presumptuous based on your posted audiogram.)
See the following clinical trial results from December 2010:

Summary:
Objective: This study seeks to assess the efficacy of the Envoy Esteem totally implantable hearing device in treating profound high-frequency sensorineural hearing loss.
Patients: Five patients with profound high-frequency hearing loss participating in a prospective, multi-center, nonrandomized Food and Drug Administration clinical trial.
Intervention: Implantation with Esteem totally implantable hearing device and comparison to baseline unaided and aided conditions.
Main Outcome Measure: Speech reception threshold and word recognition scores (WRS) at 50 dB HL presentation level.
Results: Preoperative speech reception threshold improved from an unaided 65 dB and aided 48 dB average to 26 dB with the Esteem at 12 months. WRS at 50 dB scores improved from an unaided 10% and aided 23% average to 78% postoperatively.
Conclusion: The Esteem totally implantable middle ear hearing device provides appreciable functional gain and improvement in WRS to rehabilitate hearing in patients with a profound high-frequency sensorineural hearing loss
