Patent number: 10226371Abstract: A drainage stent delivery system including an elongate shaft of a medial device, a drainage catheter or stent, and an interference fit member for selectively coupling the drainage stent to the elongate shaft. The drainage stent is selectively coupled to a distal portion of the elongate shaft by an interference fit between the interference fit member and the drainage stent such that axial movement of the elongate shaft relative to the drainage stent moves the interference fit member from a first position in which the interference fit member is engaged with the drainage stent and forms an interference fit with the drainage stent to a second position in which the interference fit member is disengaged from the drainage stent.Type: GrantFiled: April 25, 2017Date of Patent: March 12, 2019Assignee: Boston Scientific Scimed, Inc.Inventors: Andrew K. Hollett, Jacob A. Graham, Gary J. Leanna, John A. Griego, John Lane, Michael D. Amos
