The health clinic in New York City where comedienne Joan Rivers went into cardiac arrest in late August, and subsequently died, is being targeted by the comedienne's daughter in what is expected to be a multimillion dollar lawsuit.

Melissa [R] is filing a wrongful death suit against the clinic that caused Joan [L] to go into cardiac arrest

Melissa has acquired the services of the high-powered Manhattan law firm Gair, Gair, Conason, Steigman, Mackauf, Bloom & Rubinowitz, to file a wrongful death suit against Yorkville Endoscopy, and the doctors involved in performing the procedure in question.

Managing partner of the law office, Ben Rubinowitz, has also confirmed the firm's involvement in the case via a statement. "In order to fully determine all of the facts and circumstances surrounding the death of Joan Rivers, we confirm that our firm has been engaged by Melissa Rivers and her family," he said.

On August 28th, Rivers was hospitalized for going into cardiac and respiratory arrest after stopping breathing during a minor throat procedure at the clinic. Nearly a week after being placed into a medically induced coma, her grieving family decided to take her off a life support machine on September 4th, she passed away shortly after, aged 81.

The New York City Office of Chief Medical Examiner concluded that Joan's cause of death was "a predictable complication" during a routine medical procedure that resulted in a cut-off of her oxygen supply which in turn led to brain damage.

Since the controversial comedienne's untimely death, the Upper East Side clinic may be forced to shut down after the health department discovered several serious deficiencies throughout the facility.
