Abstract

The disclosure provides insertion tools and articles that facilitate entry of a medical device, such as a balloon catheter, into the body. In embodiments the insertion tools have an elongate hollow body (50) that is able to protect a portion of a medical device, such as a balloon of a balloon catheter, during an insertion procedure. In one embodiment the insertion tool has an elongate hollow body (131), a tapered distal end (135), and a locking mechanism (133) at the proximal end which can secure a portion of a balloon catheter. An opening at the distal end can allow passage of the balloon in a folded uninflated state.
