Abstract:
A catheter system, comprising:a catheter having a cylindrical member which includes a proximal end and a distal end, the cylindrical member further having at least one passageway extending from the proximal end to a distal end portion; a stand-off structure having a stand-off balloon surrounding a portion of the distal end portion, the stand-off balloon being in fluid communication with a portion of at least one passageway; a luer hub connected to the proximal end of the cylindrical member, the luer hub having a first port in fluid communication with the at least one passageway for delivering a substance to an interior chamber of the stand-off structure for inflating the stand-off balloon, the luer hub further having a second port in alignment with a first bore extending from the proximal end to the distal end portion of the cylindrical member, wherein the first bore is sealed at a point proximate to the distal end portion of the cylindrical member; a stiffening mandrel configured for introduction through the second port, the stiffening mandrel extending through the first bore within the cylindrical member for maneuvering the cylindrical member through the circulatory system; and a distal mandrel extending distally from the stand-off structure for stiffening the distal end of the cylindrical member.
