1. A method of inserting an object into a body using an insertion apparatus having an elongated housing with a distal end and a proximal end, at least one fixed handle extending from the proximal end of the housing, and a guidewire sheath clip disposed on an upper surface of the housing adjacent the proximal end; a piercing structure with a lumen disposed adjacent the upper surface of the housing, wherein the piercing structure extends from the distal end of the housing; a vacuum chamber disposed with in the housing and that communicates with the lumen of the piercing structure; a plunger configured to fit within the vacuum chamber and having a handle external to the chamber and disposed adjacent the distal end of the housing when the plunger is fully disposed in the chamber;
and a guidewire extending from the guidewire sheath clip into the lumen; a protuberance disposed on the housing between the guidewire clip and the piercing structure, the method comprising:
gripping the insertion apparatus with a hand such that one or more of a third, fourth, and/or fifth digit engages the at least one fixed handle and a second finger engages the plunger handle;
piercing the skin of a patient with the piercing structure while holding the insertion apparatus in the hand;
creating a pressure differential in the vacuum chamber by moving the plunger in a proximal direction within the vacuum chamber using the second digit;
advancing the guidewire through the lumen of the piercing structure using a first digit.
