    said outer, tubular layer being disposed over said inner, tubular layer and being physically connected to said inner layer at a plurality of locations;

    said inner tubular layer and said outer tubular layer both having substantially the same length within a range of 3-12 inches;

    said inner tubular layer being open at its distal end and a distal end of said outer tubular layer being closed to form a cone shape distally beyond said inner layer;
