Patent number: 10463509Abstract: 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 windings 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: December 14, 2016Date of Patent: November 5, 2019Assignee: C. R. Bard, Inc.Inventors: Thomas O. Bales, Jr., Peter K.

Patent number: 6969402Abstract: A helical stent having a central helically wound portion, and cylindrical ends is provided. A transition zone having struts of different lengths is provided between the helical portion and each cylindrical portion. A junction defining a strut trident is provided between the transition zone and the helical portion. This construction provides a highly flexible stent, permits connecting bridges that are in the same basic orientation, and enables the hoops of the helical, cylindrical, and transitions zones to remain “in phase” such that the stent can easily expand and collapse. According to another aspect of the invention, the kerf between adjacent struts does not go all the way to the end of those struts. The longer struts can have substantially the same flexibility and expansion force as the shorter struts of the transition by making all the kerfs approximately the same length.Type: GrantFiled: July 26, 2002Date of Patent: November 29, 2005Assignee: Syntheon, LLCInventors: Thomas O. Bales, Kenneth E. Perry

Patent number: 4582261Abstract: A pulper to convert bulky, solid wastes from food service establishments into a uniform, moist pulp. The material is pulverized in a first section and transferred as a slurry to a second section where the slurry is dewatered by an auger. To prevent clogging of the auger, a portion of the liquor extracted from the pulp is introduced as a jet stream into the upstream end of the auger to create turbulence. Additionally, a reverse flow of water through a drain chamber in excess of the amount of water required for make-up in the system is employed to prevent clogging of the screen covering the drain.Type: GrantFiled: May 18, 1984Date of Patent: April 15, 1986Assignee: AdamationInventor: Kenneth E.
