Patent ID: 6860960

Claim:
A process for sealing at least one polymeric material to a Polymeric catheter tube, comprising the steps of: providing a catheter tube having a first predetermined bonding location and a second predetermined bonding location for bonding a polymeric material thereto, each bonding location separate from each other and having a polymeric material overlapping the catheter tube at the bonding location; simultaneously generating a first and a second annular bean of electromagnetic energy from two separate energy sources, the first beam being at least partially absorbable at a selected energy wavelength by at least one of the polymeric material at the first bond site location and the catheter tube and the second beam being at least partially absorbable at a selected energy wavelength by at lent one of the polymeric material at the second bond site location and the polymeric catheter tube; controllably directing the first annular beam of electromagnetic energy by redirecting the first beam with a parabolic mirror onto the polymeric material to concentrate the energy in the first bond site location so as to at least partially melt at least one material selected from the group consisting of the polymeric material and the polymeric catheter tube along the first bond site location and immediate regions thereof; and controllably directing the second annular beam of electromagnetic energy by redirecting the first beam with a parabolic mirror onto the polymeric material to concentrate the energy in the second bond site location so as to at least partially melt at least one material selected from the group consisting of the polymeric material and the polymeric catheter tube along the second bond site location and immediate region thereof; and allowing the at least two partially melted materials to cool and solidify to form a fusion bond between the polymeric catheter tube and the polymeric material.
