Comedian Joan Rivers remained on life support on Tuesday after being hospitalized in serious condition due to cardiac arrest, her daughter Melissa said.
Rivers, 81, was hospitalized in New York last week after she stopped breathing during outpatient surgery on her vocal cords at a Manhattan clinic.
"On behalf of my mother and our family, we are extremely grateful for all the love and support we've received. At this time, she does remain on life support," Melissa Rivers said in a statement.
She added that her mother would be overwhelmed by the kindness people have shown, and thanked everyone for keeping her mother in their prayers.
Rivers, an actress and stand-up comedian known for her acerbic brand of humor, has been at Mount Sinai Hospital in Manhattan since Thursday.
The comedian, who once described herself as the "plastic surgery poster girl" and joked about her numerous procedures, stopped breathing after suffering cardiac arrest.
A representative for the comedian said media reports that her family was planning to sue the endoscopy clinic where she was treated were not true.
During her lengthy career, the husky-voiced, Brooklyn-born comedian won fame for her put-downs and was known for asking, "Can we talk?"
Rivers wanted to be an actress but got into comedy after writing sketches for television's "The Ed Sullivan Show." A career in stand-up followed. She later worked as a regular guest host for Johnny Carson on NBC's "The Tonight Show."
When she started her own late-night talk show in 1986, on the rival Fox network, it caused a falling-out with Carson that lasted until he died in 2005. Rivers' show was canceled after seven months.
Rivers also had an Emmy Award-winning daytime talk show, "The Joan Rivers Show," and later hosted “Fashion Police,” commenting on the unfortunate red carpet choices of celebrities.
Rivers won Donald Trump's reality TV show "The Apprentice" in 2009 and starred in the reality TV program "Joan & Melissa: Joan Knows Best?"
