A surgical system for performing gastrointestinal procedures is disclosed. The system includes an elongated body defining an endoscope lumen. The body is adapted to be inserted into the esophagus with a proximal end extending from a body orifice. A working member includes at least one side disposed suction cavity and a cutting device configured to excise a surface layer from the tissue that is captured in the suction cavity. One or more needles are also provided in the working portion, which can be used to apply suture to the captured tissue and/or to inject fluid into the captured tissue prior to excision. Particular applications may be to treat Barrett's esophagus, to treat GERD, or for performing gastroplasty in the stomach.

Systems and techniques for minimally invasive gastrointestinal procedures

A surgical system for performing gastroplasty is disclosed. The system includes an elongated body adapted to be inserted into the esophagus with a proximal end extending from a body orifice. A working member includes a pair of elongated suction cavities that capture and excise portions of the anterior and posterior stomach walls and apply sutures to the captured tissue, which, when drawn tight, serve to create a modified lumen in the stomach.

An in-line motor and pump assembly is supported at the bottom of a fuel storage tank by a pipe and an internal concentric conduit for housing electrical conductors extending therewithin to the motor. An impeller, coaxial with the rotor of the motor, draws the fuel into an annular passageway surrounding the stator of the motor. Further passageways convey the fuel to an annular passageway defined between the pipe and the conduit for discharge external of the storage tank. A low pressure environment attendant the inflow of the fuel is used to channel fuel for lubrication and cooling purposes to a lower journal bearing and thrust bearing supporting a common shaft for the impeller and the motor. A high pressure environment attendant outflow of fuel is used to channel fuel for lubrication and cooling purposes to a journal bearing supporting the upper end of the shaft.
