According to an embodiment of the present disclosure, a guidewire for performing medical procedures may include a central core. The central core may include a first region having a first width and a distal surface. The central core may also include a second region distal to the first region. The second region may have a second width different than the first width. The second region may also have a proximal surface. At least a portion of the distal surface of the first region may be angled relative to a portion of the proximal surface of the second region. The guidewire may also include a first covering surrounding the first region. The first covering and the first region may form a first covered region having a third width. The guidewire may also include a second covering surrounding the second region. The second covering and the second region may form a second covered region having a fourth width. The third width and the fourth width may be substantially equal.
