Abstract: A stent is made flexible along its length. The stent initially starts as a metal sheet. It is rolled in its central region to a specified wall thickness. Thereafter, the stent is photochemically etched to produce the desired cell pattern of the design of the stent. Then, the stent is folded and the metal is joined to give rise to a stent with multiple wall thickness. For instance, larger wall thicknesses at the end of the stent versus smaller wall thicknesses at its center. Various other possible manufacturing methods are useful with respect to this stent.

Abstract: A catheter is provided, adapted to be delivered to a situs in a body passageway by being contained within a sheath. The distal end of the catheter comprises an enlargement which precludes unintended distal motion of the sheath relative to the catheter.

Abstract: In a high-quality, high-speed magnetographic apparatus, an arrangement for developing the latent magnetic images of a readily-imagable magnetizable medium (in particular a relatively high-coercivity medium) with magnetically attractable toner particles. A rotatable toner developer is positioned proximate to the medium to define therebetween a toning zone, with the developer being structured to magnetically provide toner particles in contact with the medium at the toning zone and to impart to the toner particles at least at and approaching the toning zone a direction of movement relative to the medium which is in opposition to the latter. A concentration of substantially fluidized and magnetically confined toner particles is thus provided which is urged into contact with the medium for effectively developing the latent images even with the medium moving at high speed relative to the developer and without adversely affecting the latent magnetic images of the medium.

Abstract: An enclosure system includes a light-tight enclosure and a means for guiding the direction of movement of phototypesetting paper to and from the enclosure. The enclosure is capable of storing a roll of phototypesetting paper, of dispensing paper from said roll, and of returning paper onto said roll without folding or otherwise buckling the paper. The system obviates the need for a separate "take-up" enclosure and eliminates the problem of degraded print quality typically associated with characters printed at or near a fold. The enclosure comprises a container with a pivotally mounted spring-loaded lid with a gasket thereon, and a shaft disposed in the container for storing a roll of paper of selected width.
