Abstract:
1. A system for use with a source of fluid pressure, comprising: a guide member at least partially insertable into a proximal opening of a body lumen, said guide member is formed with a passageway connectable to the source of fluid pressure and operable to convey the fluid pressure into the lumen when the guide member is inserted into the body lumen, said guide member thereby allowing application of said fluid pressure upon the inner walls of the body lumen; an elongate carrier arranged for sliding movement through said guide member; and an inflatable piston head mounted on said carrier, a fluid lumen provided within said elongate carrier connected between said piston head and the source of fluid pressure for inflating said piston head, the piston head having a proximal side and a distal side and configured such that once the piston head is inflated it is configured to be advanced distally in the body lumen, due to a fluid pressure difference between the fluid pressure acting on the proximal end of the piston head and a fluid pressure acting on the distal side thereof, thereby propelling said piston head together with said carrier distally into the lumen.
