What is the test for a plaintiff to invoke federal jurisdiction in a claim for damages arising out of a medical malpractice case?

Article III "requires federal courts to satisfy themselves that the plaintiff has alleged such a personal stake in the outcome of the controversy as to warrant [her] invocation of federal-court jurisdiction." Summers v. Earth Island Inst., 555 U.S. 488, 493 (2009) (internal quotation marks and citation omitted, emphasis in original). A plaintiff must show he or she has suffered an injury in fact, the injury is fairly traceable to the challenged action of the defendant, and it is likely, as opposed to merely speculative, that the injury will be redressed by a favorable decision. Maya v. Centex Corp., 658 F.3d 1060, 1067 (9th Cir. 2011).
