Patent number: 10350393Abstract: A device for winding a filament around a structure disposed concentrically around a distal end of a balloon catheter includes a rotatable holder for retaining a distal end of the balloon catheter, a translatable winding carriage for helically winding the tensioned filament around the balloon catheter distal end, a heater for applying a predetermined amount of heat to a section of the balloon catheter having the filament wound therearound, and a controller for controlling at least the rate of rotation of the holder, the tensioning force applied to the filament, the amount of heat applied by the heater, and the rate of travel of the translatable winding carriage along the longitudinal dimension of the balloon catheter. By use of the device, the balloon is heat set and a predetermined checkering pattern of surface indentations are provided in the structure exterior surface in a single pass.Type: GrantFiled: April 24, 2017Date of Patent: July 16, 2019Assignee: C.R.

Publication number: 20090062769Abstract: Designs and methods for devices that prevent accidental or inadvertent lateral removal of a guidewire from the guidewire entry tool of a rapid exchange catheter. A first device takes the form of a funnel sized and shaped to slide into the guidewire entry tool. Another illustrative device is shaped and adapted to slide into the guidewire exit slot of the guidewire entry tool, blocking the slot until the converter is removed. In further embodiments, guidewire entry tools include a guidewire exit slot allowing for selective movement of a guidewire laterally from within a catheter. The slot may be designed with structures adapted to prevent inadvertent lateral movement of a guidewire from within the slot. The slot may be formed in a zigzag shape or may include a number of protrusions. Alternatively, the guidewire entry tool may include a split ring that rotates from a first position to a second position, the first position allowing lateral removal of a guidewire and the second position preventing such removal.Type: ApplicationFiled: April 10, 2008Publication date: March 5, 2009Applicant: BOSTON SCIENTIFIC SCIMED, INC.Inventors: David M.
