Elongated medical apparatus with inflatable tip

An elongated medical apparatus suitable for insertion into a bodily passageway of a patient for carrying out a medical procedure, comprising:

• an elongated tubular body having an outer diameter, a proximal portion and a distal portion, said distal portion terminating at a distal end, said tubular body having a plurality of lumens extending therein, said plurality of lumens comprising a larger diameter lumen and a smaller diameter lumen, said larger diameter lumen closed at said tubular body distal end, and said smaller diameter lumen open at said distal end, said elongated tubular body including at least one side port along a length thereof, said side port positioned along said tubular body such that said larger diameter lumen communicates with an environment exterior of said apparatus through said side port;
• and an inflatable member mounted to said distal end of said tubular body and extending distally therefrom, an interior space of said inflatable member in communication with said smaller diameter lumen for receiving an inflation fluid through said smaller diameter lumen distal end, said inflatable member having an outer diameter upon inflation that does not exceed the outer diameter of the tubular body.
