OPINION OF THE COURT
In this medical malpractice action, we are called upon to determine whether a suture that was improperly affixed to an organ not involved in the operation for which plaintiff sought medical treatment constitutes a "foreign object” sufficient to delay accrual of the governing Statute of Limitations until the date that the object’s presence was or reasonably should have been discovered. Because the misplaced suture is not a "foreign object” within the rule of
Flanagan v Mount Eden Gen. Hosp.
(
In June 1971, defendant George Moront, a licensed physician, performed left hernia repair surgery at defendant Columbia Memorial Hospital on plaintiff Mark Rockefeller, who was then four years old. Seventeen years later, when plaintiff’s wife was unable to conceive, plaintiff underwent a medical examination which revealed that his semen contained no sperm. Exploratory surgery performed on plaintiff in November 1989 revealed that a suture had been permanently placed on his vas deferens, most likely during the 1971 herniorrhaphy.

Plaintiff instituted this medical malpractice action against defendants Moront and Columbia Memorial in October 1990, seeking damages for his irreversible sterility and emotional distress, as well as derivative damages on his wife’s behalf.

Supreme Court denied defendants’ respective motions to dismiss on Statute of Limitations grounds and granted plaintiff’s cross motion to dismiss those affirmative defenses, holding,
inter alia,
that the action was timely because it was commenced within three years of the discovery of the misplaced suture, a "foreign object.” The Appellate Division modified, by holding that the dismissal of the Statute of Limitations defense under the "foreign object” exception was without prejudice to its reassertion if, following discovery, defendants demonstrate that there is a triable issue concerning whether plaintiffs could have reasonably discovered the malpractice "at a point in time more than three years prior to the commencement of this action.” (
The limitations period for medical malpractice actions generally runs from the date of the last act constituting the basis of the claim, and not from the date of discovery of the resulting injury
(Rodriguez v Manhattan Med. Group,
In determining whether an object which remains in the patient constitutes a "foreign object,” the courts should consider the nature of the materials implanted in a patient, as well as their intended function. Objects such as surgical clamps, scalpels, and sponges are introduced into the patient’s body to serve a temporary medical function for the duration of the surgery, but are normally intended to be removed after the procedure’s completion. Clearly, when such objects are left behind, no assessment of the medical professional’s expert judgment or discretion in failing to remove them is necessary to establish negligence. By contrast, items which are placed in the patient with the intention that they will remain to serve some continuing treatment purpose constitute "fixation devices”
(Lombardi v DeLuca,
We have previously rejected an argument that the negligent failure to remove a "fixation device” from a patient’s body transforms that material into a "foreign object”
(see, Rodriguez v Manhattan Med. Group, supra,
at 222). In so doing, we reasoned that while the "foreign object” rule applies where the negligent act of forgetting a device in the patient’s body forms the basis of the complaint, it should not be extended to cover the "very different circumstances” presented by the "failure to detect the continued presence of a previously inserted device,” a form of negligence analogous to misdiagnosis
(id.,
at 223). By parity of reasoning, a claim based on a medical professional’s deliberate implantation of a "fixation device” in the wrong place does not transform it into a foreign object. Such a claim is more readily characterized as one predicated on negligent medical treatment, which, like misdiagnosis, is a category of malpractice not covered by the "foreign object” rule
(see, Merced v New York City Health & Hosps. Corp.,
To find negligence where an object classifiable as a "fixation device” has been deliberately implanted in the patient’s body with the intent that it remain, thé trier of fact must assess "whether the defendant physician’s diagnostic methods and conclusions were consistent with contemporary professional standards of care”
(Rodriguez v Manhattan Med. Group,
*566
Applying the aforementioned principles, we conclude that the suture deliberately and permanently implanted during plaintiffs hernia operation does not constitute a "foreign object” within the meaning of the our decision in
Flanagan
simply because it was improperly placed on plaintiff’s vas deferens, an organ not normally associated with the particular herniorrhaphy procedure. Sutures have been consistently characterized in decisional law as "fixation devices” because they are deliberately introduced into the body and intended to perform the continuing function of securing the surgical closure
(see, e.g., Lombardi v DeLuca,
We are not unmindful of the harsh consequences of this ruling to plaintiff, who first discovered the misplaced suture that caused his sterility only after undergoing exploratory surgery performed 18 years after the injury-producing herniorrhaphy. However, our holding is consistent with this Court’s prior cautionary directive that the "foreign object” exception must not be broadened beyond the narrow confines announced in
Flanagan (see, Rodriguez, supra,
at 221-222, 224;
Goldsmith v Howmedica, Inc.,
Because plaintiff cannot benefit from the "foreign object” exception’s date of discovery rule, and this suit was not commenced within three years of plaintiff’s eighteenth birth *567 day — the date the infancy toll was removed — this medical malpractice action is time-barred.
Accordingly, the Appellate Division order should be reversed, with costs, the defendants’ motions to dismiss the complaint granted and the certified question answered in the affirmative.
Chief Judge Kaye and Judges Simons, Hancock, Jr., Bellacosa and Smith concur.
Order reversed, etc.
Notes
. The derivative claims of plaintiffs wife are not before this Court.
. Since the alleged act of malpractice occurred in 1971, plaintiff’s action is not governed by CPLR 214-a, which establishes a 2ti-year Statute of Limitations for medical malpractice occurring on or after July 1, 1975. Rather, the timeliness of plaintiff’s suit is governed by the three-year limitations period for medical malpractice actions set forth in CPLR 214 (6) and the decisional law interpreting the foreign object rule as enunciated in Flanagan v Mount Eden Gen. Hosp. (supra). Further, because plaintiff was an infant at the time that the alleged malpractice occurred, the accrual of this cause of action was tolled until February 25, 1985 — plaintiff’s eighteenth birthday (see, CPLR 105 [j]) — under the infancy toll of CPLR 208. Accordingly, because plaintiff’s action was commenced in October 1990, it is barred by the applicable three-year Statute of Limitations unless plaintiff can establish that the suture constituted a foreign object. If the foreign object rule applies, this action, commenced within one year of its discovery in 1989, would be timely.
