The first, second, and third elongated rod mandrels may be fixed together at predetermined proximal and distal locations and at a ball tip. The first, second, and third rod mandrels may be disposed within a tubular coupling element and fixed to the tubular coupling element at the ball tip. The tubular coupling element may be placed into abutment with and fixed to the distal end of an elongated shaft. ## Claims ### Claim 1 An elongated member comprising: a first elongated rod; a second elongated rod; a third elongated rod mandrel; wherein the first, second, and third elongated rods each include a proximal end and a flattened distal portion; wherein the first, second, and third elongated rods are fixed together such that the flattened distal portions of the first, second, and third elongated rods are arranged perpendicular to radii extending out from a shared central axis of the first, second, and third elongated rods at 120-degree radial intervals; a coupling element having a lumen and a proximal end; wherein the first, second, and third elongated rods are disposed within the lumen and are fixedly attached to the coupling element; wherein the coupling element includes a proximal portion having a first outer diameter and distal portion having a second outer diameter greater than the first outer diameter; and an elongate shaft having a distal lumen wherein the proximal portion of the coupling element is inserted into the distal lumen of the elongate shaft such that the distal portion of the coupling element abuts the distal end of the elongate shaft and is fixedly attached thereto. ### Claim 2 (depends on 1) The elongated member of claim 1, wherein the distal portion of coupling element is welded to the distal end of the elongate shaft about an entire circumference of the coupling element. ### Claim 3 (depends on 1) The elongated member of claim 1, wherein the second outer diameter is substantially equivalent to an outer diameter of the distal end of the elongate shaft. ### Claim 4 (depends on 1) The elongated member of claim 1, wherein the first, second, and third elongated rods are welded together at their proximal ends to form a ball tip. ### Claim 5 (depends on 4) The elongated member of claim 4, wherein the first, second, and third elongated rods are disposed within the lumen of the coupling element such that the proximal end of the coupling element abuts the ball tip to form a seam, and the seam is welded about an entire circumference. ### Claim 6 (depends on 1) The elongated member of claim 1, wherein the first, second, and third elongated rods are mutually fixedly attached to each other at a first point located between their respective flattened distal portions and the coupling element. ### Claim 7 (depends on 6) The elongated member of claim 6, wherein the first, second, and third elongated rods are welded to each other at the first point. ### Claim 8 (depends on 6) The elongated member of claim 6, wherein the first, second, and third elongated rods are mutually fixedly attached to each other at a second point located between the first point and the coupling element. ### Claim 9 (depends on 8) The elongated member of claim 8, wherein the first, second, and third elongated rods are welded to each other at the second point. ### Claim 10 (depends on 1) The elongated member of claim 1, wherein the first, second, and third elongated rods are made of a first metallic material. ### Claim 11 (depends on 10) The elongated member of claim 10, wherein the first metallic material is selected from the group consisting of UNS: R30003, nickel-titanium alloy, and stainless steel. ### Claim 12 (depends on 1) The elongated member of claim 1, wherein the coupling element is made of a second metallic material. ### Claim 13 (depends on 12) The elongated member of claim 12, wherein the second metallic material is selected from the group consisting of UNS: R30003, nickel-titanium alloy, and stainless steel. ### Claim 14 (depends on 1) The elongated member of claim 1, wherein the elongate shaft is made of a third metallic material. ### Claim 15 (depends on 14) The elongated member of claim 14, wherein the third metallic material is selected from the group consisting of UNS: R30003, nickel-titanium alloy, and stainless steel.
