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

Patent number: 9597207Abstract: A drainage stent delivery system including an elongate shaft of a medial device, a drainage catheter or stent, and a locking mechanism for selectively coupling the drainage stent to the elongate shaft. The drainage stent is selectively coupled to a distal portion of the elongate shaft such that the proximal end of the stent is positioned proximal of the distal end of the elongate shaft. The locking mechanism includes an engaging feature of the elongate shaft which engages a portion of the stent such that the stent may be selectively coupled to the elongate shaft through rotational motion of the elongate shaft relative to the stent. In some instances, the engaging feature of the elongate shaft may be a tab which extends into an opening of the stent.Type: GrantFiled: May 5, 2014Date of Patent: March 21, 2017Assignee: BOSTON SCIENTIFIC SCIMED, INC.Inventors: Michal Weisman, Michael D.
