Abstract:
A method for attracting and removing unwanted material or cavity from a body vessel comprising the steps of:a. providing a device including a tubular member, said tubular member having a distal end and a proximal end, a first passage and a second passage, said first passage having a proximal end and a distal end at least one orifice in the distal end of said first passage, said at least one orifice being directed generally proximally, at least one fluid jet emanating from said at least one orifice, the second passage having a proximal end and a distal end, and wherein said at least one fluid jet emanating from said at least one orifice is generally directed toward the distal end of the second passage; b. introducing the distal end of the tubular member of the device into the body vessel or cavity and bringing said distal end of said tubular member to the location of the unwanted material; c. providing pressurized fluid to supply said at least one fluid jet emanating from said tubular member via said first passage therein; d. using said at least one fluid jet emanating from said tubular member to attract the unwanted material towards said distal end of said second passage of said tubular member; e. using said at least one fluid jet to drive a flow of unwanted material along said second passage without applying suction; and, f. removing at least some of the unwanted material from the body vessel or cavity by passage into the distal end of the second passage and along said second passage toward the proximal end of the second passage.
