Publication number: 20240122615Abstract: A method for removing one or more objects or materials from a body lumen includes delivering a tube and an expandable device to the body lumen to a position proximal to the one or more objects or materials. The expandable device is positioned with a lumen of the tube, and the expandable device includes a lumen extending from a distal portion to a proximal portion. The method further includes proximally retracting the tube such that the expandable device remains in the position proximal to the one or more objects or materials, distally advancing the expandable device such that the distal portion of the expandable device at least partially surrounds the one or more objects or materials, at least partially closing a distal end of the expandable device, and moving the expandable device proximally to remove the expandable device and the one or more objects or materials from the lumen.Type: ApplicationFiled: October 16, 2023Publication date: April 18, 2024Applicant: Boston Scientific Scimed, Inc.Inventors: Enda CONNAUGHTON, Anthony O'BRIEN, Aiden FLANAGAN, Charlene DEANE, Michael HUGHES, Richard CRAWFORD, Martin Lawrence FAWDRY, Stephen McCOOEY
