This is thе second appeal arising from a products liability action filed by the plaintiff-appellee, Dorothy Marie Reeves (“Reeves”), alleging that a metal bone implant manufactured and marketed by the defendant-appellant, AcroMed Corporation . (“AcroMed”) aggravated and compounded her back injuries. In the first appeal this court vacated the district court’s judgment in favor of Reеves based on a jury verdict awarding her damages of $475,000 against AcroMed and remanded the ease for retrial.
Reeves
v.
AcroMed Corporation,
BACKGROUND
In December 1985, the plaintiff-appellee, Dorothy Marie Reeves, seriously injured her back. She was diagnosed as having spinal stenosis. To alleviate this condition, her neurosurgeon attempted a complicated procedure that entailed fusing grafts of bone from Reeves’ hip into her spine at fоur different levels of her vertebrae. As part of this surgery, metal bone plates and screws manufactured by the appellant, AcroMed, were implanted into Reeves’ back to secure the fusion. Reeves’ condition initially improved after surgery. However, six months after the surgery, Reeves began to suffer from back pain that had not existed prior to the surgery. Reeves continued to suffer from this pain and in Decеmber 1991, filed suit against AcroMed alleging that AeroMed’s products implanted in her back were defective. Reeves based her cause of action on several theories of recovery including, failure to warn, defective design, defective manufacturing, and the “unreasonably dangerous per se” category of products liability.
Reeves I,
at 308; See
Halphen v. Johns-Manville Sales Corp.,
In Reeves I, this court held that the failure to warn theory was preempted by the Medical Device Amendments to the Food, Drug, and Cosmetic Act, 21 U.S.C. §§ 301 et seq., and that Reeves failed to produce sufficient evidence to recover on her defective design and manufacturing theories. Accordingly, we vacated the judgment of the district court and remanded for retrial of Reeves’ action prеdicated solely on the unreasonably dangerous per se theory. However, in Reeves I we found that Reeves presented sufficient evidence to have her unreasonably dangerous per se claim submitted to the jury, including the questions of whether the medical device was an unreasonably dangerous per se product and, if so, whether this product condition caused the exacerbation of Reeves’ baсk injury. Id. at 308.
After trial on remand, the jury awarded Reeves $318,000 finding that AcroMed’s medical device was unreasonably dangerous per se and this product condition caused the aggravation and compounding of Reeves’ back injuries. On remand Reeves also *445 brought a cause of action based on the unreasonably dangerous per se theory of recovery against Dr. Arthur Steffee, the inventor of the metal bone plates and screws implanted in Reeves’ back and the chairman of the board of AcroMed. 1 Before the commencement of Reeves’ jury trial, the parties stipulated that if the jury returned a verdict in favor of Reeves, the judge would rule on Steffee’s liability. After the jury rendered a verdict in Reeves’ favor, the trial judge determined that Dr. Steffee was personally liable. We conclude that Reeves’ unreasonably dangerous per se claim is not preempted, the law of the case doctrine mandates that we not reconsider the sufficiency of the evidence and causation issues with respect to Reeves’ unreasonably dangerous per se claim against AcroMed, and the jury acted reasonably in awarding Reeves $318,000. However, we conclude that the district court erred in part by holding Steffee liаble.
STANDARD OF REVIEW
We employ a three-tiered standard of review in this case. A court’s findings of fact are reviewed for clear error and conclusions of law are reviewed de novo.
Peaches Entertainment v. Entertainment Repertoire,
DISCUSSION
I. Reeves’ Claim Against AcroMed
AcroMed first asserts that Reeves’ state law unreasonably dangerous per se claim is preempted by the Medical Device Amendments of 1976 (MDA or Act) to the Food, Drug, and Cosmetic Act. 90 Stat. 539. 21 U.S.C. § 301,
et. seq.
In light of the Supreme Court’s decision in
Medtronic, Inc. v. Lohr,
518 U.S. -,
Congress enacted the MDA to give the FDA authority to regulate medical devices.
Lohr,
518 U.S. at-,
Medical devices are divided into three classes. Class III devices present potential unreasonable risks and are subject to the most intensive regulation.
Id.
The metal bone plates and screws implanted in Reeves’ back are Class III devices. In order for a new Class III device to be marketed, the manufacturer of the device must provide the FDA with a reasonable assurance that the device is both safe and effective.
Id.
(citing 21 U.S.C. § 360e(d)(2)). This process, known as the “premarket approval” (PMA) process, is quite rigorous in that the FDA spends an average of 1200 hours on each submission.
Id.
at---,
There are two exceptions to the PMA requirement. First, the statute grandfathers in all pre-1976 devices and allows those devices to remain on the market until the FDA initiates and completes a PMA.
Id.
at-,
However, all “substantially equivalent” devices are subject to the requirements of 21 U.S.C. § 360(k). That section imposes a limited form of review on every manufacturer intending to market a new device by requiring it to submit a “premarket notification” to the FDA. This process is also known as the “§ 510(k) notification or process,” after the *446 number of the section in the original act. We will use it hereinafter to avoid confusion between 21 U.S.C. § 360(k)(§ 510(k) notification or process) and 21 U.S.C. § 360k(a)(pre-emption provision). If the FDA concludes on the basis of the § 510(k) notification that the dеvice is “substantially equivalent” to a preexisting device, it can be marketed until the FDA initiates the PMA process for the underlying pre-1976 device to which the new device is “substantially equivalent.” Id. In contrast to the rigorous PMA process, the § 510(k) process averages only 20 hours instead of 1200. Id.
The preemption provision of the MDA, 21 U.S.C. § 360k(a), reads as follows:
§ 360k. State and local requirements respecting devices
(a) General rule
Except as provided in subsection (b) of this section, no State may establish оr continue in effect with respect to a device intended for human use any requirement—
(1) which is different from, or in addition to, any requirement applicable under this chapter to the device, and
(2) which relates to the safety or effectiveness of the device or to any other matter included in a requirement applicable to the device under this chapter.
In
Medtronic, Inc. v. Lohr,
518 U.S. -,
Although the Supreme Court determined that it need not go beyond § 360k(a)’s preemptive language to determine whether Congress intended the MDA to pre-empt at least some state law, citing
Cipollone v. Liggett Group, Inc.,
The Court determined that the Lohrs’ design claims were not pre-empted because the FDA’s “substantially equivalent” determination as well as its continuing authority to exclude a device from the market do not amount to a specific, federally enforceable design requirement that cannot be affected by the type of state law pressures imposed by those claims. Because the § 510(k) process is focused on
equivalence,
not safety, the Court observed, substantial equivalence determinations provide little protection to the public. Neither the statutory scheme nor legislative history suggests that the § 510(k) process was intended to do anything other than maintain the status quo, which included the possibility that a device’s manufacturer would have to defend itself against state law negligent design claims.
Lohr,
518 U.S. at ---,
The Supreme Court also held that the Lohrs’ manufacturing and labeling claims are not pre-empted because § 360k(a) does not
*447
prе-empt state rules that merely duplicate the FDA’s rules regulating manufacturing practices and labeling. That the state requirements may be narrower than the federal rules does not make them “different” under § 360k(a).
Id.
at -,
In the present case, we conclude, for the same reasons, that Reeves’ unreasonably dangerous per se claim is not preempted by § 360k(a). As the Supreme Court noted, quoting the court below with approval, “ ‘[t]he 510(k) process is focused on
equivalence,
not safety.’
Lohr v. Medtronic, Inc.,
In concluding its review with respect to the Lohrs’ defective design claims, the Court stated:
Thus, even though the FDA may well examine § 510(k) applications for Class III devices (as it examines the entire medical device industry) with a concern for the safety and effectiveness of the device ..., it did not “require” Medtronics’ pacemaker to take any particular form for any particular reason; the agency simply allowed the pacemaker, as a device substantially equivalent to one that existed before 1976, to be marketed without running the gauntlet of the PMA process.....There is no suggestion in either the statutоry scheme or the legislative history that the § 510(k) exemption process was intended to do anything other than maintain the status quo with respect to the marketing of existing medical devices and their substantial equivalents. That status quo included the possibility that the manufacturer of the device would have to defend itself against state-law claims of negligent design____ [T]he Court of Appeals properly concluded that the “substantial equivalence” provision did not pre-empt the Lohrs’ design claims.
Id.
at ---,
Applying these principles to the present case, we conclude that the “substantial equivalence” provision did not pre-empt Reeves’ unreasonably dangerous per se claim. When Reeves’ claim arose, Louisiana and many other jurisdictions recognized that a product may be unreasonably dangerous because of its design for reasons very similar to those underlying the unreasonably dangerous per se claim. This widely recognized defective design theory accrued when ‘.‘[a] reasonable person would conclude that the danger-in-fact, whether foreseeable or not, outweighs the utility of the product.”
Halphen v. Johns-Manville Sales Corp.,
This court’s decision in
Feldt v. Mentor Corp.,
Considering the background behind the “substantial equivalence” exemption, the fact that the purpose of Congress is the ultimate touchstone in every pre-emption case,
Lohr,
518 U.S. at -,
Alternatively, AcroMed asserts that the judgment of the district court should be reversed because there was not sufficient evidence from which a reasonable juror could find that the medical device was unreasonably dangerous per se and that this condition of the product caused the aggravation of Reeves’ injuries. In Reeves I this court concluded, however, that Reeves’ evidence was sufficient to supрort submitting her unreasonably dangerous per se claim to the jury, including the questions of whether the product was unreasonably dangerous per se and whether that product condition caused the exacerbation of Reeves’ back injuries. On this appeal these issues are controlled by the law of the case doctrine.
Under the law of the case doctrine, we follow the prior decisions in a cаse as the law of that case. Thus, we will not reexamine issues of law addressed by a prior panel opinion in a subsequent appeal of the same case unless: “(i) the evidence on a subsequent trial was substantially different, (ii) controlling authority has since made a contrary decision of the law applicable to such issues, or (iii) the decision was clearly erroneous and would work a manifest injustice.”
Alberti v. Klevenhagen,
We find nothing improper or unreasonable regarding the jury’s verdict with respect to the quantum of damages. In light of the deference that we are required to give, we cannot overrule the jury’s verdict in this case. The record indicates that the jury’s award of compensatory damages to Reeves was within reasonable bounds.
*449 II. Reeves’ Claim Against Dr. Steffee
Finally, we address' whether the district court erred in holding Steffee liable as the manufacturer or supplier of an unreasonably dangerous product. Under product liability theories of recovery, the plaintiff must establish that the defendant was the manufacturer or supplier of the defective product.

See e.g. Halphen v. Johns-Man-ville Sales Corp.,
CONCLUSION
For the foregoing reasons, the judgment of the district court in favor of Reeves is affirmed insofar as it was rendered against AcroMed but it is reversed insofar as it affects Steffee. Accordingly, the judgment of the district court is AFFIRMED IN PART AND REVERSED IN PART.
Notes
. In Reeves I, Reeves also brought a claim against Dr. Steffee, but the parties apparently agreed not to submit the claim against Dr. Steffee to the jury because AcroMed’s insurance would cover any judgment. However, Dr. Steffee was never dismissed as a party.
. The Louisiana Supreme Court has recognized that professional vendors may also be subject to liability under product liability theories.
