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

Publication number: 20180185620Abstract: A medical instrument such as a guidewire that is designed to have controlled torque transmission along its length. Specially treated areas are placed in selected and equal areas along the entire length of the elongated shaft of the medical instrument, and are separated from one another by untreated areas. This process ensures that any torque is transmitted distally, in a smooth manner, regardless of the guidewire position, thus resulting in a substantial reduction in whipping. In one embodiment, a stainless steel guidewire is utilized, and is subjected to annealing heat treatment in selected areas. This annealing process creates a mandrel that has repeated temper properties along its length. Torque applied at one end of this mandrel is transmitted to the opposite end in an even and controlled manner, even when the mandrel is formed into a loop.Type: ApplicationFiled: August 14, 2017Publication date: July 5, 2018Applicant: BOSTON SCIENTIFIC SCIMED INC.Inventors: John A. Griego, Patrice A. Weststrate
