Abstract
The present invention provides a method for assembling a medical device using solvent bonding techniques. The method includes the steps of: (1) providing a first article of a polymer composition having (a) a first component of a homopolymer or copolymer obtained using monomers of cyclic olefin or a bridged polycyclic hydrocarbon, the first component being present in an amount from about 30% to about 100% by weight of the composition and (b) a second component from 0-70% by weight of the composition; (2) providing a second article of a material selected from the group of low crystallinity polymers; (3) applying a solvent to one of the first article or the second article to define an interface area; and (4) bonding the first article to the second article along the interface area.
