OPINION
Plaintiffs appeal the district court’s denial of leave to amend their complaint in this product liability action and the grant of summary judgment to Defendant Med-tronic, Inc. based on this court’s earliеr decision in
Kemp v. Medtronic, Inc.,
BACKGROUND
Plaintiffs collectively sued Defendant alleging defects in Defendant’s pacemaker leads implanted in them or their spouses. Their cases were consolidated with
Kemp v. Medtronic, Inc.,
No. C-1-97-103, 1999 (N.D. Ohio June 27, 1997) for the purposes of discovery. After all cases were consolidated in the Southern District of Ohio and after the district court denied Plaintiffs class certifiсation, consolidation for trial, and permissive joinder, the parties agreed to administratively close all claims save
Kemp.
That case was fully litigated and appealed.
Kemp v. Medtronic, Inc.,
After resolution of the Kemp cаse, Plaintiffs filed a motion to reinstate their actions and file an amended complaint to present new causes of action that federal law does not preempt, and to raise arguments that are distinguishable from the arguments made in Kemp. Defendant did not oppose reopening the case and moved the court to grant it summary judgment pursuant to a motion it had earlier filed at the conclusion of the Kemp appeal.
Plaintiffs’ proposed amended complaint comprised eight counts. Counts I and II alleged post-sale “failure to warn” and post-sale “failure to recall” сlaims against Defendant based on “information learned after FDA review of the Model 4004/4004M PMA Supplement Applications.” 1 Count III alleged that Defendant failed “to [cjomply with [fjederal [r]equire- *423 mеnts [consistent with [s]tate [requirements.” (“Medtronic failed to comply with applicable CFR regulations in its Model 4004/4004M PMA Supplement applications.”). Count IV alleged Defendant’s “Negligence Per Se” in its “fаilure to comply with the [Food and Drug Administrations’s (FDA) ] conditions of approval.” Counts V through VIII reasserted claims originally plead by Plaintiffs in their original complaint with greater factual specificity.
The district court disposed of Plaintiffs’ motion to amend in three separate opinions and then granted summary judgment to Defendant in a final opinion. In the first opinion, issued on December 10, 2001, the district court found that counts V through VIII were directly precluded by
Kemp.
It also found that count IV was preempted because it was, in essence, a disguised fraud on the FDA claim. The district court found that federal law рreempts such claims (citing
Kemp
and
Buckman Company v. Plaintiffs’ Legal Committee,
Plaintiffs failed to file the required amended complaint within the allotted time and, instead, on January 14, 2002, requested that the court reconsider its decision. Before the court ruled оn that motion, the parties requested a stay to allow them to engage in settlement discussions. The court granted the stay. After lifting the stay, on November 11, 2002, the district court denied Plaintiffs’ request to recоnsider its earlier decision. On December 13, 2002, Plaintiffs then requested leave to amend their complaint to allege the claim the court had previously allowed.
In its third opinion, filed on September 10, 2003, the district court denied Plaintiffs leave to amend their complaint, as previously allowed, holding that justice did not require granting Plaintiffs leave at that time, because of the opportunities given them to amend their complaint in a more timely fashion. The district court also expressed concern that Defendant would be unduly prejudiced were it to grant Plaintiffs leave to amend in viеw of how much time had elapsed since Plaintiffs filed their original complaint. The district court also directed Plaintiffs to show cause why it should not grant Defendant’s motion for summary judgment. Finally, on January 13, 2004, aftеr Plaintiffs filed a response to the show cause order, the district court granted summary judgment to Defendant on the remaining claims. This appeal followed.
.On appeal, Plaintiffs allege threе errors. First, Plaintiffs claim that the district court erred in denying them leave to amend their complaint to allege that Defendant was negligent per-se in failing to comply with the FDA’s conditions of apрroval (count IV of the proposed amended complaint). Second, Plaintiffs allege that the district court erred in denying them leave to amend their complaint to assert Defendant’s рost-sale failure to warn and post-sale failure to recall claims (counts I and II of the amended complaint). Finally, Plaintiffs request that this court revisit its holdings in Kemp (and consequently reverse the district court’s denial of leave to amend for counts V through VIII). Plaintiffs did not appeal the district court’s denial of leave to amend count III of the proposed amended complaint.
*424 ANALYSIS
We rеview de novo the district court’s determination that granting Plaintiffs leave to amend would be futile.
See Ziegler v. IBP Hog Market,
Federal law also preempts proposed amended counts I and II because those counts would impose state requirements “different from” or “in addition tо” the federal requirement.
See
21 U.S.C. § 360k(a) (“no State or political subdivision of a State may establish or 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.”). As recognized in
Kemp,
the FDA requires continuous updates as part of the pre-market approval (PMA) application and supplement process.
Kemp,
Finally, Plaintiffs ask us to revisit our holding in
Kemp.
We may not do so. “A panel of this Court cannot overrule the decision of another panel. The prior decision remains controlling authority unless an inconsistеnt decision of the United States Supreme Court requires modification of the decision or this Court sitting en banc overrules the prior decision.”
Salmi v. Secretary of Health and Human Services,
CONCLUSION
For the foregoing reasons, we AFFIRM the decision of the district court.
Notes
. Paragraphs 41 and 48 of these two counts read: "These duties are independent of any obligation a manufacturer may have tо comply with applicable federal regulations.”
. There appears to be significant disagreement between the parties over whether Minnesota or Ohio law applies to this dispute. That question is irrelevant to our disposition of these issues. Federal law would preempt Plaintiffs’ claims regardless of whether Minnesota or Ohio law applied.
