US Patent:

6878162, Apr 12, 2005

Filed:

Aug 30, 2002

Appl. No.:

10/231666

Inventors:

Thomas O. Bales - Coral Gables FL, US
Peter K. Kratsch - Sunrise FL, US
Kenneth E. Perry - Bainbridge Island WA, US

Assignee:

Edwards Lifesciences AG - Horw

International Classification:

A61F002/06

US Classification:

623 115, 623 122

Abstract:

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 a preferred design, 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.

International Classification:

US Classification:

623 115

Abstract:

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.

Filed:

Mar 7, 1988

Appl. No.:

7/164681

Inventors:

Kenneth W. Perry - Miami FL

International Classification:

E04B 702

US Classification:

52 90

Abstract:

A system for the formation of a sloped roof surface on a pre-existing flat roof deck through the utilization of a mold assembly comprising a plurality of angularly configured beams spaced from one another and cooperatively interconnected with baffle plates and an overlying grill structure having a substantially open or pass-through construction to the extent that a confined space defined by the above set forth component is to be filled with a light-weight cementitious or other operable material preferably suitable for roofing, resulting in an inclined or sloped outer surface being formed contiguous with the grill structure such that the cured cementitious material and aforementioned components become a substantially integral, one-piece construction permanently secured to the pre-existing, original flat roof deck.
