A balloon for use in compressing cancellous bone and marrow against the inner cortex of bones whether the bones are fractured or not. The wiping element includes at least one isolation pad formed thereon and wherein the isolation pad defines a portion of increased lateral width of the wiping element. According to the invention, the interior of the enclosure is disinfected with each washing procedure. A tuning current applied through a continuous strip of HTS material in the magnetic driver induces a repulsive magnetic force causing the movable substrate to move with respect to the fixed substrate. The guide provides a handle for holding the trochar, reducing effort. The first lead frame has an embedded portion embedded in the recess portion.
