Abstract
A medical device in which a melt processed part has different crystallized properties at different locations. The part is formed of a polymer composition by inclusion a of polymer crystallization modifier in the composition making up at least a portion of such part, the amount of the polymer crystallization modifier is varied at different locations on the part in accordance with the desired difference in crystallization behavior.
Claims9
A catheter tube or medical balloon having a length and comprising at least one layer of a polymer material composition that varies along its length,
- in at least a first portion of said length, the polymer material composition in said at least one layer comprises a thermoplastic base polymer and a crystallization enhancer, and
- in at least a second portion along said length the polymer material composition comprises said thermoplastic base polymer and a crystallization inhibitor.
