Patent number: 9554927Abstract: A stent includes a central portion of helically wound undulations formed of struts, cylindrical end portions, and transition zones between the helical portion and the cylindrical portions. According to a first aspect of the invention, the torsional flexibility of the stent is maximized by having bridges connecting adjacent winding be interrupted by the maximum possible number of undulations. In one embodiment, each winding includes nineteen undulations around the circumference, bridges are provided every five undulations. According to a second aspect of the invention, uniform opening of the transition zone is achieved by altering the width, and thereby the flexibility, of a series of struts in accordance with their lengths. Specifically, the long transition zone struts are made wider.Type: GrantFiled: August 19, 2013Date of Patent: January 31, 2017Assignee: C.R. Bard, Inc.Inventors: Thomas O. Bales, Peter K.

Publication number: 20170000481Abstract: Surgical instruments and their methods of use are described. In one embodiment, a surgical instrument includes a power transmission including a trigger and a fastener driver operatively coupled to the trigger. Actuation of the trigger from a first configuration to a second configuration moves the fastener driver between at least a first position and a second position. Additionally, an actuation lockout system operatively associated with the power transmission is moveable between a locked configuration and an unlocked configuration. The actuation lockout system prevents movement of the fastener driver from the first position to the second position when the actuation lockout system is in the locked configuration. Actuation of the trigger from the first configuration towards the second configuration moves the actuation lockout system from the locked configuration to the unlocked configuration.Type: ApplicationFiled: June 30, 2015Publication date: January 5, 2017Applicant: C.R.
