Patent number: 11576774Abstract: 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.Type: GrantFiled: June 29, 2020Date of Patent: February 14, 2023Assignee: Surmodics, Inc.Inventors: Bruce M. Jelle, Joram Slager, Joseph S. McGonigle, Rick Murphy, Andrew G. Bach, Teryl L. Woodwick Sides, Ambereen Angamuthu, Sean Lundquist, Gary Opperman, Nathan A. Lockwood
