Abstract:
A method of expanding an interstitial cavity of a body structure to promote tissue growth and volumetric augmentation of the body structure, comprising the steps of:providing a tissue dilation system comprising a source of fluid, a catheter element for carrying fluid to an interstitial cavity of the body structure, a valve element for restricting back flow of fluid and an attachment element for forming a pressure resistant seal that couples the catheter element and the interstitial cavity into fluid communication;coupling the tissue dilation system to the interstitial cavity; andintroducing fluid under pressure into the interstitial cavity such that at least some of the fluid contacts the body structure and dilates a tissue wall of the interstitial cavity for a period of time such that tissue growth and volumetric augmentation occur, and such that the body structure retains an increased volumetric capacity after removal of the fluid from the body.
