Christopher H Porter: Self-expanding prosthesis having stable axial length. Schneider, Haugen and Nikolai, November 12, 1991: US05064435 (1084 worldwide citation)

A body implantable stent consists of two or more generally tubular, coaxial and slidably connected stent segments. Each of the stent segments is of open weave construction, formed of multiple braided, helically wound strands of resilient material. The stent is elastically deformed to a reduced radiu ...

Ni Ding: Method of applying drug-release coatings. Schneider, Pennie & Edmonds, November 9, 1999: US05980972 (527 worldwide citation)

The invention is directed to a method of applying drug-release coatings whereby a polymer can be dissolved in a first solvent (solvent A) to form a polymer system and a drug can be dissolved or suspended in a second solvent (solvent B) to form a drug system. The coating or layer of coating so formed ...
