Sasori-Donna, How does he die?

yes....when Sasori is about to attack Chiyo with a poisned bladed sword, Sakura comes in the way and gets hurt...he tries to pull the sword out of her, but she doesnt let go of him....then Chiyo makes the Father and Mother puppets put a sword through Sasoris heart(cylindrical thing on his chest)...and then he dies after telling Sakura about Orochimaru's spy n all
