Abstract
A detachable balloon system includes an inflatable balloon with a self-sealing valve. The balloon has an elastomeric membrane and a proximal opening. The self-sealing valve is made up of a valve body for receiving an inflation instrument to inflate the balloon. The valve body is preferably formed of a biocompatible elastomeric material and includes a base portion and a sealing portion. The base portion is bonded to the elastomeric membrane so as to seal the proximal opening of the balloon. The sealing portion is located within the balloon and extends distally from the base into the balloon. The sealing portion is compressibly sealable in response to a pressure within the balloon following inflation of the balloon and removal of the inflation instrument. A balloon dispenser for housing a balloon prior to receipt of an inflation instrument is also described.
