Method for solvent bonding polyolefins

A method for assembling a medical device using solvent bonding techniques comprising the steps of:

• providing a first article of a polymer composition comprising
• a first component of a homopolymer or copolymer obtained using monomers of cyclic olefin or a bridged polycyclic hydrocarbon by addition polymerization, the copolymer having at least about 20 mole percent of the cyclic olefin monomer or the bridged polycyclic hydrocarbon monomer, the first component being present in an amount from about 30% to about 99% by weight of the composition, and a second component in an amount from about 1% to about 70% by weight of the composition;
• providing a second polymeric article of a material selected from the group consisting of low crystallinity polymers;
• applying a solvent to one of the first article or the second article to define an interface area;
• and
• bonding the first article to the second article along the interface area.
