Publication number: 20020123791Abstract: A stent with an increased vessel coverage includes a plurality of radially expandable cylindrical elements generally arranged on a common longitudinal stent axis and interconnected by one or more interconnecting members placed so that the stent remains flexible in a longitudinal direction. Each cylindrical element is formed in a generally serpentine wave pattern having alternating valley and peak portions which is capable of nesting when crimped or placed in a compressed condition. The valley portions and peak portions may be V-shaped and W-shaped elements which have different longitudinal lengths which permit the nesting of the cylindrical element. The stent can be made to be expandable by an external force, such as a balloon expandable dilatation catheter, or can be self-expanding when made from a material which is self-expanding.Type: ApplicationFiled: December 28, 2000Publication date: September 5, 2002Inventor: William J. Harrison

Patent number: 5391401Abstract: In curtain coating, uniform layer or layers are only obtained if the operational variables are held within precise limits. These limits define a "coating window". However, one of the boundaries of this "window" is governed by the occurrence of air-entrainment. Described herein is an improved coating process in which allows the "coating window" to be enlarged. This is achieved by using a material adjacent the support on to which the liquid material is to be coated which readily shear-thins.Type: GrantFiled: June 17, 1993Date of Patent: February 21, 1995Assignee: Eastman Kodak CompanyInventors: Terence D. Blake, Rosemary Dobson, Gregory N. Batts, William J. Harrison
