I have a note from Furinkan here, it seems VIZ did a good job at translating the double meaning though.

"The shinigami tool that Rokumon uses to revive Rinne is called a "hazumidama capsule" (弾み玉カプセル). Hazumi can mean "bouncing" (as in bouncing ball which is what the item looks like) but it can also mean "to stimulate" or "to become lively" which is what the ball is meant to cause Rinne to do."

Also, he's so little on the ball.
