Abstract
The present invention provides a method for using a polymeric cement to assemble medical devices. The method includes the steps of: (1) providing a first article of a low crystallinity polymer; (2) providing a second article of a low crystallinity polymer; (3) providing a cement composition having a first component of a cyclic olefin containing polymer or a bridged polycyclic hydrocarbon containing polymer and a second component of an effective amount of a solvent having a solubility parameter of less than about 20 (MPa)1/2; applying the cement composition to one of the first and second articles to define a bonding area; and (4) attaching the first article to the second article along the bonding area to fixedly attach the first article to the second article.
