Appeal No. 1998-3366 Application No. 08/591,506 Considering first the § 103 rejection of claim 1, this claim calls for a catheter system that includes an expandable stent capable of permanent deformation when expanded releasably attached to the inflatable portion of a catheter by a bond having certain capabilities, including the capability “of separating from said stent member and remaining with said inflatable portion . . . upon inflation of said inflatable portion to permit deployment of said stent member” (claim 1, emphasis added). Lau, the examiner’s primary reference, pertains to a catheter system comprising a catheter member 11 having an inflatable portion 14 and an expandable stent 10, capable of permanent deformation when expanded, attached to the inflatable member. Lau describes the attachment of the stent to the inflatable portion of the catheter as follows: A variety of means for securing the stent to the expandable member on the catheter for delivery to the desired location are available. It is presently preferred to compress the stent onto the balloon. Other means to secure the stent to the balloon include providing ridges or collars on the inflatable member to restrain lateral movement, or using bioresorbable temporary adhesives.
