1. A method for removing an object from a body lumen, comprising:
- dispensing fluid into the body lumen;
confining a predetermined quantity of the dispensed fluid within a portion of the body lumen that contains the object by impeding a flow of the fluid at a distal end and at a proximal end of the portion of the body lumen; and
releasing the predetermined quantity of fluid through the proximal end of the portion of the body lumen to propel the object past the proximal end of the portion of the body lumen.

32. A method of displacing an object within a body lumen, comprising:
-
providing a medical device comprising;
a fluid dispenser defining an aperture for dispensing a fluid into the body lumen;
a distal expansible member connected to the fluid dispenser and located distal of the aperture; and
a proximal expansible member located proximal of the aperture, both the distal and proximal expansible members configured for deployment between a collapsed state and an expanded state;
locating a portion of the medical device within the body lumen such that the distal expansible member is located distal of the object;
expanding the distal expansible member until it seals against a wall of the body lumen;
dispensing fluid through the aperture and into the body lumen; and
wherein the dispensed fluid causes displacement of the object such that a portion of the object and a portion of the fluid flows proximally past the proximal expansible member and in between the wall of the body lumen and an outer surface of the proximal expansible member. - View Dependent Claims (33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47)

48. A method of displacing an object within a ureter, comprising:
-
providing a medical device comprising;
a fluid dispenser defining an aperture for dispensing a fluid into the ureter;
a distal expansible member connected to the fluid dispenser and located distal of the aperture; and
a proximal expansible member located proximal of the aperture, both the distal and proximal expansible members configured for deployment between a collapsed state and an expanded state;
locating a portion of the medical device within the ureter such that the distal expansible member is located distal of the object;
expanding the distal expansible member until it seals against a wall of the ureter;
dispensing fluid through the aperture and into the ureter; and
wherein the dispensed fluid causes displacement of the object such that a portion of the object and a portion of the fluid flows proximally past the proximal expansible member. - View Dependent Claims (49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60)
