A catheter assembly and method for constructing same comprises the engagemen t of a substantially hollow proximal tubular member, which is at least partial ly coated with at least one polymeric material, to a substantially distal outer tubular member. The proximal tubular member and the distal outer tubular member define at least one continuous central lumen therethrough. At least a portion of the distal outer tubular member is disposed about at least a portion of an inner tubular member. A portion of the inner tubular member is engaged to a portion of the proximal tubular member. A portion of the inner tubular member is engaged to a portion of the end region of the distal outer member. An end region of the proximal tubular member extends distally into t he distal outer tubular member adjacent to the inner tubular member.
