1. An apparatus for performing maxillary membrane elevation comprising:
- a fluid source;
a fluid delivery tube;
an electrically operated pump connected to said fluid source and pumping said fluid to said tube;
a baffling element arranged to absorb pressure variations in said tube resulting from the operation of the pump; and
a sleeve sized and shaped to be inserted in a patient to provide maxillary membrane elevation when receiving fluid through said tube.

Abstract
An apparatus for performing a maxillary sinus membrane elevation is described having a peristaltic or other electronic pump providing a fluid to a sleeve extending to the maxillary sinus through a handle. A pressure sensor monitors the fluid pressure and if the pressure reaches an excessive pressure level, the fluid flow is cut off to protect the membrane. Pressure variations in the fluid pressure due to the operation of the pump are reduced or eliminated using one or more baffles.

8. An apparatus for performing maxillary membrane elevation comprising:
-
a peristaltic pump generating a fluid output with pressure variations; a handle having a fluid connector, a fluid input and a fluid path connecting said fluid connector to said fluid input; a sleeve adapted for positioning to extend into the maxillary cavity for said membrane elevation, said sleeve being selectively coupled to said connector; a tube connecting said pump to said input to provide said fluid; a baffle positioned to absorb said pressure variations; a pressure sensor arranged to sense a fluid pressure at said sleeve; a controller coupled to said pressure sensor and adapted to automatically turn said pump off if said pressure reaches a limit. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19)
