MEMORANDUM **

Todd Kenneth Horob, a federal prisoner, appeals pro se from the district court’s judgment dismissing his action brought under Bivens v. Six Unknonm Agents of Fed. Bureau of Narcotics, 403 U.S. 388, 91 S.Ct. 1999, 29 L.Ed.2d 619 (1971), challenging the validity of his conviction and the conditions of his confinement. We have jurisdiction under 28 U.S.C. § 1291. We review de novo a dismissal under 28 U.S.C. § 1915A. Resnick v. Hayes, 213 F.3d 443, 447 (9th Cir. 2000). We affirm.

The district court properly dismissed without prejudice Horob’s action because his allegations against the United States regarding his trial necessarily imply the invalidity of his conviction, and Horob has not shown that his conviction has been invalidated. See Heck v. Humphrey, 512 U.S. 477, 487, 114 S.Ct. 2364, 129 L.Ed.2d 383 (1994) (§ 1983 complaint in which “a judgment in favor of the plaintiff would necessarily imply the invalidity of his conviction or sentence ... must be dismissed unless the plaintiff can demonstrate that the conviction or sentence has already been invalidated”); Martin v. Sias, 88 F.3d 774, 775 (9th Cir. 1996) (applying Heck to actions brought against federal actors).

We do not consider arguments, including those regarding access to the law library, made for the first time on appeal. See Smith v. Marsh, 194 F.3d 1045, 1052 (9th Cir. 1999). Issues not raised in the opening brief, including those regarding conditions of confinement, are deemed waived. Id.

Horob’s remaining contentions are unpersuasive.

AFFIRMED.
