Publication number: 20140324152Abstract: 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: ApplicationFiled: July 14, 2014Publication date: October 30, 2014Inventors: Andrew K. Hollett, Jacob A. Graham, Gary J. Leanna, John A. Griego, John Lane, Michael D. Amos

Patent number: 8845552Abstract: 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: GrantFiled: September 14, 2012Date of Patent: September 30, 2014Assignee: Boston Scientific Scimed, Inc.Inventors: John A. Griego, Patrice A. Weststrate

Patent number: 8771288Abstract: A medical instrument converts linear movement of a shaft at a proximal end of the instrument to a rotational movement of an end effector of the instrument. According to one embodiment, the medical instrument includes an end effector formed of a snare loop connected to a shaft that is located within a sleeve. Once the sleeve is located near a desired location within a patient, the snare loop may be rotationally positioned with linear movement of the shaft by the operator. The shaft is formed with a threaded portion that matches threads formed in a torque transmitter element fixed within the sleeve. Linear movement of the shaft through the torque transmitter element causes the shaft to rotate. The medical instrument may also include a pivot connector for reducing torque build-up of the shaft and/or a clutch assembly for restricting controlled rotation of the snare loop to only one direction.Type: GrantFiled: February 28, 2013Date of Patent: July 8, 2014Assignee: Boston Scientific Scimed, Inc.Inventors: John Griego, Yem Chin, Gary McAlister
