Abstract:
1. A medical device positionable in a hole in a bone of a human body, the medical device comprising: a first tubular body possessing a size and configuration permitting the first tubular body to be positioned in the hole in the bone of the human body; a lumen extending through the first tubular body, the lumen possessing a first opening at one end of the lumen permitting a liquid to be introduced into the lumen and also possessing a second opening at an opposite end of the lumen permitting the liquid in the lumen to be discharged from the lumen and into the hole in the bone, the lumen possessing an inner circumference at the second opening; an expandable body fixed to the first tubular body and surrounding an interior space in fluid communication with the lumen in the first tubular body so that the liquid in the lumen of the first tubular body flows into the interior space of the expandable body and outwardly expands the expandable body to cause the expandable body to contact an inner surface of the bone surrounding the hole to fix the medical device in position in the hole in the bone; an inner diameter of the lumen possessing a size which gradually decreases from the expandable body toward the second opening at the opposite end of the lumen so that the liquid introduced into the lumen by way of the first opening at the one end of the lumen and flowing toward the second opening at the opposite end of the lumen enters the interior space of the expandable body and outwardly expands the expandable body into contact with the inner surface of the bone surrounding the hole; a second tubular body positioned in the lumen and possessing an outer circumference at a distal-most end of the second tubular body; and wherein the outer circumference of the second tubular body at the distal-most end of the second tubular body is smaller than the inner circumference of the lumen at the second opening so that the liquid in the lumen is dischargeable from the second opening and into the hole in the bone when the second tubular body is positioned at the second opening.
