In еarly 1989, following five unsuccessful pregnancies, Betty Ferguson again became pregnant. She went to the emergency room at D.C. General Hospital on June 12 and June 17, 1989, complaining of abdominal pain and cramps, and was treated on an outpatient basis. She returned to the hospital on June 18, 1989, with the same complaints. Approximately one-half hour after arriving at the hospital, a fetus weighing eleven ounces emerged from Ms. Ferguson. Upon emergence, 1 the fetus had a heartbeat and engaged in some form of respiratory effort. Within a short time, however, these functions ceased and the fetus died.
Ms. Ferguson brought this action in Superior Court against the District of Columbia (“the District”) on behalf of the fetus under the local survival statute, D.C.Code *16 § 12-101 (1989). 2 The complaint alleged that the employees of D.C. General Hospital, which is owned by the District, were negligent in failing to admit her to the hospital and in failing to provide the treatment necessary to prevent her fetus from emerging prematurely. 3 As legal representative of the fetus, Mrs. Ferguson sought recovery for the damages suffered by the fetus as a cоnsequence of that negligence, including its death. The District moved for dismissal or in the alternative for summary judgment on the ground that the fetus was not viable and therefore had no cause of action under the survival statute. The trial court granted the motion for summary judgment. 4
Appellant presents two arguments in seeking reversal of the summary judgment: first, that because the fetus emerged alive, a cause of action existed under the survival statute regardless of whether or not the fetus was viable; second, to the extent that viability is relevant, the fetus’s viability was a disputed issue of fact preventing the grant of summary judgment. We think existing case law mandates the rejection of both arguments on the record before us and accordingly we affirm the judgment.
I.
We first address apрellant's argument that because the fetus emerged alive a cause of action existed under the survival statute. In
Greater Southeast Community Hosp. v. Williams,
We revisited this area of the law in
Jones v. Howard University,
We take the viеw that to authorize the mother to pursue, in her own right, claims for injury to a non-viable fetus represents a more orderly approach to the adjudication of such claims than does a requirement that such claims be pressed as wrongful death and survival claims.
Id.
at 423. Thus, we established that during the period of non-viability, the cause of action pertained to the mother and not to the non-viable fetus.

Since, as
Williams, supra,
Appellant attempts to distinguish these cases by arguing that if a non-viable fetus is “born alive,” which she asserts is the case here, that fact should be decisive for purposes of the survival statute. We think that this approach is foreclosed by the reasoning of Williams, where we expressly rejected live birth as the line in determining fetal rights. Just as a viable fetus that is injured possesses rights under the survival statute whether death occurs prior to or subsequent to birth, likewise, the existence of rights vel non of a nonviable fetus under the survival statute cаnnot turn on that happenstance either. 9 The concept underlying our survival statute is that the representative is merely bringing a lawsuit that decedent could have brought had he or she not died. Where the fetus emerges from the mother without the developmental capacity to survive, it would contradict the theory of a survival action to provide a cause of action to the representative of the fetus. Absent clear indication of contrary legislative intent, it would be anomalous to view an action as one that could have been brought by the fetus had the fetus not died when the fetus had never developed the capacity to survive in the first place. Indeed, the logic of viability rather than physical emergenсe of the fetus as the dividing line in interpreting the survival statute is inherent in the concept of viability itself, an issue to which we now turn in dealing with appellant’s second argument.
II.
Appellant argues that even if viability is the correct line in determining when a cause of action on behalf of the fetus exists under the survival statute, the question of whether the fetus here was “viable” was a disputed quеstion of fact that precluded the grant of summary judgment.
Appellant argues that because the fetus was “born alive,” that is, with a heartbeat,
*18
it was necessarily viable. Appellant’s argument, however, is based upon a misunderstanding of the concept of “viability,” at least for the purposes of the survival statute. In the
Bonbrest
case, which formed the basis for our jurisprudence in this area, the court stated that “the term ‘viable’ means that the foetus has reached such a stage of development that it can live outside of the uterus.”
Bonbrest, supra,
In the case before us, it is undisputed that Ms. Ferguson’s pregnancy had not progressed beyond twenty and one-half weeks. In its motion for summary judgment, the District presented authority for the proposition that no fetus at that stage of development сan survive apart from its mother, even with artificial aid. The District referred to decisions of the United States Supreme Court such as
Roe v. Wade, supra,
Thе earliest point at which a fetus can survive is 23-24 weeks_
[[Image here]]
While even more of the ... approximately 24-28-week[ ] fetuses are expected to survive in the near future, there is an “anatomic threshold” for fetal survival of about 23-24 weeks of gestation_ This is because the fetal lung does not mature sufficiently to permit normal or even mechanically assisted respiration ... before week 23-24 of gestation.
*19 The District also presented a portion of the deposition testimony of its own expert, Dr. John W. Larsen, Jr., who testified regarding the alleged respiratory effort of a fetus at such an early stage of pregnancy. Dr. Larsen explained that the fetus could “make little chest motions, but there are no lungs with open alveoli behind them to supрort them. It is like an early reflex chest motion_” 11
In contradistinction to this extensive authority, appellant presented a one-sentence conclusory assertion by its expert that “[i]t is my professional opinion that to a reasonable degree of medical certainty that the Ferguson child was born viable.” The expert included no specific bases for this conclusion, 12 nor were any other facts offered by appellant in support of her position. Moreover, and importantly, the expert gave no definition of the precise concept of viability to which his opinion was addressed.
Summary judgment may be granted if the moving party demonstrates through “ 'the pleadings, depositions, answers to interrogatories, and admissiоns on file, together with the affidavits ... that there is no genuine issue as to any material fact and that the moving party is entitled to a judgment as a matter of law.’ ”
Nader v. Toledano,
In light of these principles, we think that summary judgment was proper here. In light of the District’s particularized and extensive presentation, the expert’s mere unsupported contrary assertion was insufficient to create the requisite genuine issue of fact as to viability within the legal definition of that term.
See Weight-Rite Golf Corp. v. United States Golf Ass’n,
[A]ny affidavits offered in opposition to the [summary judgment] motion must set forth “specific facts” that would be admissible in evidence in order to show that a genuine issue exists for trial. This [r]ule applies equally to affidavits submitted by experts. While the expert may base his [or her] opinion on facts or data reasonably relied upon by experts in the field, and this data need not be admissible in evidence, an expert’s affidavit must nevertheless set forth specific facts in order to create an issue of fact for trial. Theoretical speculations, unsupported assumptions, and conclusory allegations advanced by an expert ... are not entitled to any weight when raised in opposition to a motion for summary judgment.
Bell v. Swift Adhesives, Inc.,
More importantly, appellant had the obligation to demonstrate that her expert was applying the legally correct definition of “viability” for purposes of this litigation under the survival statute rather than using the term as synonymous to merely being alive. If by asserting that the fetus was viable, appellant’s expеrt meant no more than that the fetus emerged alive, then the issue of whether the fetus had the developmental capacity to survive outside of its mother remained undisputed. All of appellant’s arguments presented to the trial court on the issue of viability indicated that appellant was applying an incorrect definition of the term for purposes of the survivаl statute, and in this posture there was no reason to think that appellant’s expert was not doing likewise.
III.
We emphasize that we are deciding only the issue before us, a matter of interpretation of a particular statute dealing with a narrow issue of tort law. We hold that under existing law, the District of Columbia survival statute, D.C.Code § 12-101 (1989), does not grant to the legal representаtive of a non-viable fetus any cause of action brought in the name of the fetus, and that on the record in this case, summary judgment was properly granted under that principle.
Affirmed.
Notes
. We use the word "emergence" as a neutral term to describe what appellant calls a "birth” and appellee calls a "miscarriage.”
. That section reads: "On the death of a рerson in whose favor or against whom a right of action has accrued for any cause prior to his death, the right of action, for all such cases, survives in favor of or against the legal representative of the deceased.”
. No claim was made that the death of the fetus was due to insufficient care by hospital personnel after the emergence of the fetus.
. In addition to the claim under the survival statute, both parents sought damages in their own right. The grant of summary judgment on these other counts is not contested on appeal.
. Several years before
Jones,
we recognized the distinction between injuries to a viable fetus and injuries to the mother, making clear that the mother has a cause of action for her own injuries quite apart from those that the fetus might have for injuries to it under
Williams. See Coughlin v. George Washington Univ. Health Plan, Inc.,
. The twins were subsequently born healthy in all respects.
. We had recognized this same dichotomy in
Coughlin, supra

. The only extant case on this exact point of which we are aware is presently рending after argument before the Supreme Court of Pennsylvania.
See Hudak v. Georgy,
. Chief Justice Rehnquist delivered the opinion of the Court in
Webster
as to parts I, II-A, II-B, and II-C. As to parts II-D and III, which contained the above quoted language, the Chief Justice wrote an opinion in which Justices White and Kennedy joined.
See also Casey, supra,
. We are not unmindful of the consideration recognized by the Supreme Court that viability cannot be determined solely by reference to one particular factor, "be it weeks of gestation or fetal weight or any other single factor,”
Colautti v. Franklin,
. He stated only that he had reviewed the medical records and that he questioned a rating of the physical condition of the fetus (apgar scores) in light of the fact that it had "a beating heart” and "obvious respirations.”
. We note again that no malpractice was alleged with respect to the treatment of the fetus after its emergence.
