US Classification:

623001110, 434262000, 606108000

Abstract:

Devices and methods for stent advancement, including methods for instructing another or others how to advance a stent into an anatomical structure or into a testing/demonstration synthetic structure, such as a polymer tube. The advancement may be achieved by at least two periods of stent engagement that drive a stent distally from a sheath separated by a period of non-engagement.

Assignee:

DTM Corporation - Austin TX

International Classification:

B22F 102
B22F 326

US Classification:

419 2

Abstract:

A method of fabricating articles, such as prototype parts and prototype tooling for injection molding, is disclosed. The method begins with the fabrication of the article in a "green" state by the selective laser sintering, or another additive thermal process, applied to a composite powder, preferably a powder of metal particles coated with a thermoplastic polymer. Both the green article and also an aqueous emulsion of a thermosetting material are then preheated to a temperature below the glass transition temperature of the thermoplastic polymer, and the green article is then infiltrated with the aqueous emulsion. The thermosetting material may be a thermosetting polymer with an appropriate cross-linking agent, or may be a cross-linking agent that will react with the thermoplastic binder polymer. After infiltration, the article is dried, and a rigid skeleton of a thermosetting material is now present within the structure of the article. Further processing may now be performed.

International Classification:

B27N 300
B32B 3100

US Classification:

1562728

Abstract:

A powder for use in selective laser sintering, from which prototype articles and masters for molds may be formed, is disclosed. The powder is formed by spray drying a polymer emulsion to yield a distribution of particles of substantially spherical shape. The powder is then air classified to remove excessively small particles from the distribution; the powder may also be screened to remove large particles therefrom, as well. The resulting distribution of particle sizes, by volume, preferably has a mean particle size of between about 20. mu. and about 50. mu. , with preferably less than about 5% (by volume) of its particles with a size of less than about 15. mu. and less than about 2% (by volume) of its particles with a size of greater than about 75. mu. The powder is subjected to selective laser sintering to produce an article of approximately 55% to 75% of theoretical density. The article may be used as a prototype article or part, or as a pattern or master for a mold.
